The Hottest Questions About Air Conditioning

Do you want to know about Air Conditioning? Here are some frequently asked questions.

1. Air conditioning: Like it or hate it?

I love AC. I love being cold. I have the windows open in the dead of winter. I really do not know why- maybe it's my Scandinavian blood, maybe it's a hormonal imbalance

2. Ice Block in Air Conditioning?

First thing is to turn off the unit outside and leave the blower running inside as your coil is also a solid brick of ice, run the blower for a few hours and keep checking the air vents as you will notice an increase of air flow as the coils defrost. You could have a couple of problems, one could be that your coil is dirty which is preventing the proper air flow which will ice up the coil or you have low freon. Hope this helps Bill

3. does a dog need air conditioning?

ummmmmm i dont think they know what it is

4. Heat spell and no air conditioning?

Hi. You can buy good used window ac's in the want ads of the newspaper. Have a cool, cool summer. edit: Fans do not remove the heat, only move it around.

5. Air conditioning 12 entire stadiums?

Have you ever seen the Palm Islands? Better yet, have you ever been on them? When you have, rethink your question

6. Should we put in air conditioning?

You already have air conditioning. The basement walls and floor are much cooler than the air. Heat alwasy move toward cold. So the external heat from air is transferred to the walls and floor and continues into the soil beyond. The source of heat on hot days is mostly outside air coming down the stairway bringing humidity with it. The other heat source is the ceiling which is the floor of the house. As you are covering the walls you are slowing the heat transfer to the outer walls but eventually it gets there anyway. I do not recommend insulating the outside walls because any moisture should be allowed to escape into the basement. That prevents mold. You could insulate the basement ceiling which would reduce noise going up or down. You would appreciate that when one of your kids starts drum practice or gets a LOUD stereo with horrible music. By the time they are teenagers, you will hate all their music and wish you had double insulated when you had the chance. Forget the AC, but you probably will need a dehumidifier. Humidity once it enters the basement is trapped. It actually feels colder with high humidity than low. So a dehumidifier will make the air feel warmer. I do not know if it actually is but it feels that way. Or you can install a small low volume box fan in one of the windows. Turn it on as needed but it will draw air from other parts of the house or outside, even down your dryer vent. So just put in a matching vent on the opposite side of the basement to provide outside air when it's on. The important reason for this is to remove the humidity and provide some fresh air. Dehumidifiers eat electricity like it is free. The fan is a cheaper alternative. If you have a force air heating system, whole house AC is easy. It goes right on top the furnace with the condenser outside. You usually get a seperate electric meter for reduced rates if the power company can remotely shut it off for a couple hours a day during peak usage times. You do not need that now if ever. When the kids get too old to use the backyard pool then you can add it. A finished basement would not affect it at all. And the ducting will cool the basement while the cool air cools the rest of the house. You are a wise young couple the way you are paying for this. Do not be swayed. If nothing else, tell your dad this is your husbands decision and you can not change his mind. That should be enough to silence your dad. He never liked your husband anyway.

7. Dog gets weak around air conditioning?

Get it a heating pad to sit on when the air is on. They need warmth

When Using Just the Fan of an Air Conditioning System, Is It the Outside Air That Is Flowing Or It I
It depends on the system type and the functionality provided.Residential air conditioning systems are usually 100% recirculating, and if you want outdoor air in the space you open a window or windows.Commercial systems, systems serving commercial or public buildings, may have an economizer, which is capable of drawing in 100% outside air when outdoor conditions permit (i. e. cool enough), and they draw in 15-20% outdoor air all the time as ventilation air to the space.The fan-only option can be useful in 100% recirculating residential systems if there are temperature differences throughout the house, hot rooms and cold rooms for example; running the fan will 'stir-up' the space and even out the temperatures without running the condensing unit (outdoor air conditioner) or furnace. If the temperature difference is due to an air balance problem, better to balance the system with the modulating dampers at each diffuser, but if it's a problem in the afternoon in a west-facing room with lots of windows, for example, the fan alone can be helpful. When using just the fan of an air conditioning system, is it the outside air that is flowing or it is just the inside air that is just turning round?1. Do you know anyone who uses a geothermal heat pump for their home heating and air conditioning?A/C that can run backwards is as good of a short description as any. Uses 'free' heat, you just have to pay to move it. Sound technology, but not for every locale or application. Cost: Hard to say, but I would not be suprised by a bid of $15,000 to $20,000. Supplement: Part of the system is 'emergency heat'. Essentially electric coils (a.k.a. electric furnace). It is used to cover heat needs when the capacity is reached. Expensive when its called. Most residential electric service has two-phase electric service (208vac). The largest compressor normally available for 208vac is 5-ton. 1-ton equals 12,000 BTUs... so 5-tons equals 60,000 BTUs. 60,000 BTUs an hour is the capacity of the refrigerant system to move heat. If your home ever exceeds 60,000 BTUs of heat loss, then the emergency heat will kick on... and the meter will spin. You could install multiple heat pumps, but the installation cost multiplies also. Try a search here on heat pumps. No, I am not being cheeky, there is just a lot of good info here and it is too much to regurgitate it all. Bottom line, it can mean some very low utility bills if sized and installed properly, but a very expensive mistake if not.2. How can I cool a room without fans or air conditioning?keep it clean, turn the lights out, shut off all electricity not in use (computers& tv's inclusive) and open the windows3. How do I stop my household Central Air Conditioning from tripping my circuit breaker?I definitely would be concerned. It has been very hot this summer. Your AC unit is probably dirty and drawing excessive current. It might work fine (or seem to) when it's 90, but the dirt on the outside coil will prevernt good heat transfer when it's 102. Clean it. Clean it. Clean it. Clean it. You would be very surprised the difference a good cleaning can make on an air conditioning system.4. What alternative tent materials can you use for a very large tent the size of a school hall to lower the cost of air conditioning?Tents are tents, normally constructed of the same canvas everywhere, but suppliers in the north and deep south have padded/insulated materials. Check the internet and your local party equipment supplier/rental. Note that number of occupants can be the largest factor in cooling. Use the 'rule-of-thumb' of 75 Watts of heat radiated by each person.What alternative tent materials can you use for a very large tent the size of a school hall to lower the cost of air conditioning?5. How Did People Survive Without Air Conditioning In the Past?Sat on the front porch fanning themselves and drinking iced tea during the hot part of the day. I do not think I could've stood it6. How Big Should Obama's Carbon Tax be to Get Elderly to Cut Back on Heat & Air Conditioning?As big as it takes

Questions That Show Insufficient Effort by the OP
If you hover your mouse over the downvote button, you get this tip: "This question does not show any research effort; it is unclear or not useful." The help section "What types of questions should I avoid asking?" does not say anything about insufficient research effort. This suggests to me that ofeeshul policy is to downvote these, not close.I normally leave a comment explaining my downvote, quoting or paraphrasing the text in the downvote button's tip. If I don't do this, the OP will probably have no idea that I downvoted and will not learn that (IMO) there was a problem with the question.IMO there is nothing wrong with having questions and answers that cover exactly the same information that's available somewhere else like Wikipedia. WP is not perfect, and WP is a different type of collaborative environment than SE, with different strengths and weaknesses. Many seemingly obvious, trivial questions are FAQs, and one of the strengths of SE is that we have mechanisms for collecting correct answers to FAQs in a single place and then avoiding wasting our time by answering those FAQs againI see regular questions that could be answered by some basic Googling. Examples would be In a large city how much hotter on average is it outside due to the air conditioning of all the buildings? and Quantum annealing computing.To be charitable, newcomers to physics may not know where to start and what terms to search for, and a suitable answer might be to point them at a few introductory articles. However in many cases it looks as if the OP simply can't be bothered to put any effort in. Do we have a policy for closing (or not closing) such questions. For homework we have the "off topic/need to show some effort" reason, but most of the questions of this sort aren't obviously homework.Or am I just being excessively grumpy? :-)

Curtains for a Non-air-conditioned Apartment in the Tropics
I grew up in the 1940s and 1950s in hot, humid south Louisiana and hot, less humid Dallas, Texas. We had no a/c in Louisiana and starting in about 1954 in Dallas we had window units in some rooms, but not in the bedroom I shared with my brother. In 1960 we moved to a new house in Dallas, Texas with central a/c. The improvement in comfort was astounding.After leaving home I sometimes lived in downscale student digs without a/c and it was sub-optimal, but obviously tolerable. One place was cooled with an "evaporative cooler" or water fan. Mumbai is presumably too humid for those to be effective. For two years in my mid twenties I lived comfortably without a/c in Fiji near Suva, but Fiji's summer high temperatures are low compared to Dallas or Mumbai. If you can afford it, I do not think you should deny yourself a/c in Mumbai on the grounds of damage to the environment.But as far as other interventions on your existing house, outside louvers over the windows would be better than curtains inside. Louvers would reduce solar gain while still allowing airflow into the room. The sun will heat the louvers but much of the heat will stay outside.We live in Mumbai - West coast of India, tropics. Summers are from March to July with temperatures reaching early 40 degree Celsius and a lot of humidity. It rains from July to September with temperatures in mid to late 30 degree Celsius. Octobers are hot like summers. November to March the temperatures dip to late 20 degree Celsius.We live on the sixth floor of an apartment building in an non-air-conditioned house. Ceiling fans provide ventilation. We do not want to have air-conditioning as we believe it's harmful for the environment.Our bedroom and living room have a 10ft X 4ft East facing window each. Two other rooms have same sized windows facing North and 5ft X 4ft windows facing East.In the summers, things heat up quite a lot. What type of curtains should we use to make the house as comfortable as possible? Will it help if we plant vines in pots and let them crawl up the window grills? Also, should we use the same curtains during winters?·OTHER ANSWER:We live in Mumbai - West coast of India, tropics.

How Can I Determine Why My Lights Flicker When the a/C Is Running?
What, if any work was done to the electrical system when you renovated and the problem started? In addition, what, if any work was done on the house in the immediate vicinity of the electrical service entrance?Do you happen to own a non-contact thermometer (or know someone you could borrow one from?)If this is a bad connection (and that's my guess), it will be heating itself (more or less depending on how much current loads in the house are drawing) - ie, if your microwave draws 10 amps, it's heating itself with 20 watts (10A X 2V) when you run that - if your AC draws 30 amps it will be heating with roughly 270 Watts (30A x 9V)Lacking a non-contact themometer you can sometimes find these by touching the grounded exterior of electrical enclosures and feeling for heat. Having one means you can also look at specific parts inside the panel (but the problem may not be there - it may be in the meter box, which you generally can't open yourself anyway.)Ideally you'd start at some point when nothing much has been using electricity in the house, or you've actually shut off the main for several hours, go around and feel/measure temperatures, then turn on the power and turn on as many loads as possible and feel/look for an area that is getting much warmer than the rest of the wiring/enclosures.Since you are evidently comfortable in the open service panel, you can also check for voltage differences between the incoming wire and the terminal it connects to, and/or see if the voltage you measure is very different (under load) if measured from terminal to terminal or from incoming wire to incoming wire. That checks that end of the meter-to-service cables - the other end you generally need an electrician or the power company to check.It is important to find and solve this issue before it gets worse; you're in the early stages of "how electrical fires get started" IMHO.My lights considerably flicker whenever a large load comes on in the house and it has been this way since we renovated five years ago. I am attempting to troubleshoot this now and have already probably waited longer than I should have. I did some reading and ultimately removed the cover of the main panel and tested across the two hot wires at the main panel. All circuits were active. The reading I received was 245 /- 2V, meaning average of 245V but fluctuated between 243V and 247V. I then had my wife turn our whole-house air conditioning unit on and voltage dropped to 237 /- 1V while AC was running. Is this a normal voltage drop when a large appliance is turned on or is this indicative of an issue?·OTHER ANSWER:My lights considerably flicker whenever a large load comes on in the house and it has been this way since we renovated five years ago.

Fighting Air Conditioning/'s Peak Demand with Thermal
As we head into the hottest part of summer in the Northern Hemisphere, in what could be the hottest year on record, we barely give a thought to what using air conditioning does to our electricity grid. And what it will do to a hotter world in the future.According to a recent Department of Energy report, the world is gearing up to install 1.6 billion new air conditioners by 2050. While air conditioning is a common luxury in the United States, in most other countries it is not that common. As these countries become wealthier and grow in population, they will install large amounts of air conditioning. Air conditioner sales are rising in India, Brazil and Indonesia by about 15% per year.Of course this is a good thing. Air conditioning cansave lives during extreme weather. However, air conditioning is the main contributor to peak electricity demand in the summer. During extremely hot days or heat waves, this jump in energy demand leads to blackouts and brownouts, keenly felt in the most populated parts of the country. Energy prices also jump during these times where supply and demand combine to as much as quadruple the costs.Although energy use is dependent on a region's climate, a central air conditioner will generally run 3 to 7 months of the year, using between 3 and 5 kW of power every hour for around 9 hours a day during the hotter months. This averages to about 3,000 kWhs per year. So 1.6 billion new air conditioners will require an additional 4.8 trillion kWhs of electricity every year - the output of 400 new GenIII nuclear plants, 1000 new coal plants or a million wind turbines.Unfortunately, much of this electricity will be concentrated during peak hours, necessitating the use of peaker plants. Peaker plants operate only to make up the difference between base load and peak load. Our current energy grid makes these plants necessary, but they come at a steep price. Peaker plants are usually natural gas or coal, but can also use jet fuel, oil and diesel.Peakers usually run for short periods of time and so are less efficient and dirtier than conventional base load fossil fuel plants. Though natural gas is certainly cleaner than coal, natural gas does have some environmental issues from fracking, to pipelines, to fugitive emissions of methane. And lots of CO2 emissions, if you care about that.The commercial sector accounts for about a third of the total energy consumption in America and, according to data from the EIA, air conditioning use makes up 10 to 15 percent of that total consumption. In some southern regions, cooling can make up 25 percent of energy use in a large building.To combat this hot strain on the grid, commercial buildings can take advantage of thermal energy storage. In fact, they must take advantage of this strategy or we will have some major problems in the coming decades.Thermal energy storage allows cooling to be created at night, when there is excess capacity from the utility, and stored for use the next day during peak times. During off-peak hours, cold water, or even ice, is made using this energy and stored inside some type of energy storage tank. The stored ice is then used to cool the building's occupants the next day. Alternatively, the facility may run on energy storage or just the chiller depending on cooling demands or the availability of onsite renewable resources such as solar and local tariffs. This provides greater flexibility to smarter and zero energy buildings. Thermal storage systems have the ability to store renewable energy like wind, which mainly blows at night.As Mark MacCracken of CALMAC noted, "Air conditioning had its roots in stored cooling. Some of the earliest air-conditioned public spaces were movie theaters in New York City that made ice in the basements before the shows. But ice was eventually abandoned as a way to air-condition because soon electricity became so cheap that instantaneous creation of cooling became the norm."But now we have a problem supplying that much energy instantaneously, and environmental consequences that we have to address.The promise of thermal energy storage is similar to having a big party. You're not likely to start making ice the moment people arrive. You'd buy or make ice ahead of time, store it in your freezer, and use it as needed. In this case, you still make the ice ahead of time, but at night when the electricity you use is much less expensive.There are many types of thermal storage systems, but one that is particularly suited to commercial buildings is CALMAC's IceBank. It is presently being used in over 4000 commercial buildings in more than 35 countries, including notable installations in Rockefeller Center and JCPenney's headquarters which has had this technology for 25 years.There are no moving parts within the tanks, so they can last over 40 years. This strategy saves on energy costs since night time energy is roughly 50% cheaper than daytime energy, once demand charges are added.On-peak CO2 emissions in summer months are nearly double off-peak emissions, with almost 1 ton of CO2 per MWh as opposed to ½ ton of CO2 per MWh during off-peak times. Replacing natural gas or coal peaker plants with thermal energy storage would greatly improve air quality and reduce all those emissions. In PGE territory, thermal energy storage would provide CO2 savings of about 55% overall, and up to 96% CO2 savings per MWh of on-peak electricity.Fighting global warming with thermal energy storage is so ice!

The Hottest Questions About Air Conditioning
Do you want to know about Air Conditioning? Here are some frequently asked questions.1. What to do if your air conditioning (A/C) is broken?A landlord must supply reasonable air conditioning and cooling in units that have an air conditioning unit installed, or where air conditioning is offered. Arizona law provides remedies that tenants may use when the air conditioning fails in the tenant's rented home. However, these remedies are not available if the tenant, tenant's family, or guest caused the air conditioning to stop working by a deliberate or careless act, or failing to act. If the landlord fails to supply air conditioning, the tenant must give written notice to the landlord and wait for the landlord to make the needed repair. Notices may be hand-delivered to the landlord (or to the landlord's authorized agent) or sent to the landlord by certified mail. It is strongly recommended that notices be hand-delivered, as notices sent by certified mail are deemed to be received on the date the landlord actually receives the notice or 5 days after the notice is mailed, whichever occurs first. The tenant should make sure to keep copies of any notices given to the landlord so that they can show them to the court. If the landlord fails to make the repair within a specific timeframe, the tenant may do ONE of the following 5 options. Give written notice (Form A: "Notice of Failure to Provide Adequate Air Conditioning and Notice of Tenant's Remedy") that the landlord has 5 calendar days to make the repair. If the landlord does not timely make the repair, the tenant can then decide whether to terminate the lease and leave. If the tenant decides to terminate the lease, they will need to provide an additional notice (Form B: "Notice of Intent to Vacate and Request for Inspection") that states the intended move-out date. The tenant will be responsible for any rent during this time. See A.R.S. 33-1361(A). Give written notice (Form A: "Notice of Failure to Provide Adequate Air Conditioning and Notice of Tenant's Remedy") that the landlord has 5 calendar days to make the repair. If the landlord does not timely make the repair, the tenant may bring a lawsuit for an injunction (to force the landlord to make the repairs) and for money damages. See A.R.S. 33-1361(B). Give written notice (Form A: "Notice of Failure to Provide Adequate Air Conditioning and Notice of Tenant's Remedy") that the landlord has a reasonable time to repair. If the repair is not timely made, the tenant can choose to procure reasonable amounts of air conditioning or cooling themselves. What does this mean? Examples include purchasing fans or a window-mounted air conditioning unit. If the tenant takes these steps, the tenant will be able to deduct the "actual reasonable cost" from the rent. The tenant must keep all receipts from these purchases and be able to prove that they purchased the items after the deadline stated on the notice that the tenant gave the landlord for fixing the air conditioning unit. See A.R.S. 33-1364(A)(1). Give written notice (Form A: "Notice of Failure to Provide Adequate Air Conditioning and Notice of Tenant's Remedy") that the landlord has a reasonable time to repair. If the repair is not timely made, the tenant can choose to pay for reasonable, temporary substitute housing (such as renting a hotel room) until the landlord repairs the air conditioning in the home. Just like with the other remedies, the tenant will need to keep all receipts, so the tenant can prove that substitute housing was only used for the time period from the deadline stated on the notice until when the air conditioning was restored to the home. Warning: The tenant may deduct a maximum of 125% of the monthly rent amount for the substitute housing. For example, if the air conditioning is out for a month and the rent is $800 per month, the tenant will be excused from the full $800 and can be reimbursed for up to $200. If the air conditioning is out for a week and the rent is $800 per month, the tenant can be excused for up to $250. See The tenant may deduct a maximum of 125% of the monthly rent amount for the substitute housing. For example, if the air conditioning is out for a month and the rent is $800 per month, the tenant will be excused from the full $800 and can be reimbursed for up to $200. If the air conditioning is out for a week and the rent is $800 per month, the tenant can be excused for up to $250. See A.R.S. 33-1364(A)(3)2. heating/air conditioning?The air conditioning and the heater are two separate things in a car. A car heater is really simple : it uses the heat an engine produces and just vents it inside the car. That's why you do not get heat before the engine gets hot. It's free energy that would be lost anyways.

Find Answers to the Hottest Questions About Air Conditioning
Considering that Air Conditioning may still be new to many people, we provide ten common questions and answers about Air Conditioning for you to get started.1. Does an open window upstairs affect air conditioning?Let it go. It's not worth being the evil step mother. Pick your battles2. Why did air conditioning suddenly stop on 2000 Ford Taurus?unlike some of the other answers I love my 97 Taurus. It has over 212,000 miles and runs great. You need to specify more about the ac problem to get an answer though.3. does using the air conditioning in your car waste gas?In some ways, both are right. Your dad's grasp of physics is correct- there is no "free energy." The heat in the car is excess heat from the motor and the air that blows from the heater comes from the battery. That's true. How much *extra* gas you use by blowing air across the heater core is really minimal. You use "extra" electricity when you play the radio or use your lights or power windows. While this is technically "extra," the amount is negligible. So blowing hot air does use extra gasoline, but the amount is so minimal that no one worries about it. The air conditioner is another matter. When you turn on the A/C, you do two things- you get air from a blower (like the heater) and you engage a clutch that the motor drives, powering the freon pump. How much "extra" gas you use depends on your car and other mileage factors. I would say if you use the A/C over 100 miles, you could expect a 1-2 mpg drop. Is it a "waste?" That depends on your subjective judgment. Staying comfortable has a value. So using more fuel is correct, but it depends on your personal decision to use that extra bit of gas to stay comfortable. Everything has a value. Let's say it takes you two hours to drive that 100 miles. And your car gets 25 mpg. So instead of using 4.0 gallons, you use 4.1 gallons. At today's prices, that's an extra $0.40 you are using (I do not ' like "waste.") Is it worth $0.20/hour to be comfortable? You can do a few simple things to make sure you do not "waste" gas. Air up your tires to the recommended max. Do not do unnecessarily fast acceleration. Reduce your cruising speed. Plan your driving so you do not make unneeded trips. And while not a fuel-saving activity, shopping for cheap gas is a money-saving benefit. If you are a sensible driver, burning a bit of extra gas may not be "wasting" gas. Take care!!!4. Toyota Camry 2007 where to refill air conditioning?I strongly recommend you take it to an A/C professional. It is very unlikely your 4 year old car needs recharging, and if it does the large leak must be repaired first. It is far easier to damage the compressor by overcharging than to properly charge it at home. I see so many questions in Cars and Transportation asking what to do when they charged the system a week ago and it is blowing warm air again - they either have an unrepaired leak or the compressor needs replacement. A normal A/C service is about $100; a compressor replacement in your 2007 Camry is between $1500 and $1900 (first source). It is your choice5. What is the most probable issue with the air conditioning in a car?well the recharge means a leak. have to use freon which is expensive now, and also find the leak. could also be the compressor switch (not so bad) or the compressor itself ( way bad.) 150 up to 10006. What is wrong with the air conditioning in my 1996 Cadillac Eldorado?The need to replace the entire compressor not just the casing7. What in the world is wrong with my cars air conditioning?Go ahead and turn it back on and run it for about 5 minutes. I suspect that you will get no cooling. I think they may have over charged your system and as a result either an o-ring blew out or the evaporator (the part inside the dash that actually transfers the cold to the air) sprung a leak. The coolant is not toxic to people in the amount you might have breathed. If you do get cooling, post an update and describe the noise as best you can and try to identify if it is coming from in the dash or under the hood it may be a compressor or fan issue and that information will be helpful in getting you on the right track

Find Answers to the Hottest Questions About Air Conditioning
Here are top 10 questions about Air Conditioning asked by people online.1. Is it possible to put air conditioning in a 65' mustang??It was a dealer option that was hung under the dash and you could put a original system on it, but your better off to get one of the aftermarket systems2. Does Air Conditioning in car works on CNG?you opt for to discover the compressor less than the hood. turn on the A/C and look on the middle of the pully on the compressor. If it keeps taking off and preventing, this is low on refrigerant. someone with a pair of gauges can allow you to recognize what is incorrect in 2 minutes. If the compressor is operating, and the lines coming from it are warm and chilly the air mixture door on your vents is undesirable3. Central Air Conditioning in Michigan?listen to calli, get a lot of local bids, every home is specific when it comes to sizing the unit, what is existing, how many windows, doors, insulation, returns (if there is only heat now, guessing there is no hi-lo returns) you are gonna need an a coil, condenser, pad, whip, and stat wire (minor), get your bids, it might be more beneficial to get another window unit to get you through this heat and humidity that we are having right now, that and do not be in a hurry to buy, you may, and im not gonna say its will happen, but with this heat, it will be a market in favor of the person/company installing it, if you wait a little you may see prices lower a little. best bet i would say is to get another window unit, get your bids and plan for next year4. Air conditioning bang noise?If the main trunk line is made of metal as opposed to flex board, it might just be moving when the fan stops blowing causing the sound5. Is $9500 too much for a new heating and air conditioning system?get more bids and see... just do not take the cheapest one6. Air conditioning in basement apartment?they have air conditioners on wheels at home depot and lowes that you vent a small tube outta a window which work quite well7. Are air conditioning costs affected by the heat index?The heat index is a way of relating temperature and humidity to human perception. That is to say, the combination of 91 deg F dry-bulb temp and high humidity makes it feel like 109 deg dry-bulb and 25% humidity. What this means is that you have high humidity, and high humidity can make it more expensive to run your AC, This is because your AC is working to remove the moisture from the air (Latent load) instead of cooling it down (sensible load), so instead of getting 55 deg air off the coil you may only get 59 deg. If you are just recirculating your air there is not much extra load. If you are bringing in ventilation from the outside, then your AC is wokring harder.8. Who replaces air conditioning and coolant hoses?any mechanic should be able to easily9. Looking for Air Conditioning Solutions for a VW Caravelle 1986?Adding a/c to a non a/c car is a major PITA. There were plenty of companies back in the 60's that made retro-fit kits to bring a/c in to cars that did not have it "factory Installed". There are other companies that may still make those style of kits, but the viability of that is questionable. You can try finding the same car in a wrecking yard and take out the controllers, wiring harness, refrigerant lines, (both hi-and-low), then you would need the compressor, mount brackets, condenser, evaporator, housing, and usually a 4 speed fan. If you have a water cooled engine, then you would need a new thermostat, and a larger core radiator, as well as a 2 speed electric radiator fan. This is about all that I can think of for a "factory" unit. There is also the possibility that you can get a self-contained unit that would mount on the top of the car as many RV's do, that is run by a 12Vdc or a 120 vac motor, but I would think that you would need to upgrade your alternator for that, if you have a "standard 65 amp Alt. as that is a good place to start.

Some Questions About Air Conditioning Answered
Do you want to know about Air Conditioning? Here are some frequently asked questions.1. Help required with air-conditioning!?It's like torque&horsepower in that it has a time factor. The complete term is Day Ton, meaning the amount of heat absorbed by one ton of ice within 24 hours. And, do not forget to consider moisture removal from the air when sizing a system. Removing moisture is the most important job of an air conditioner. Do not just "let the thermostat do it's job"2. Window air conditioning unit question?unless things have changed, the screen is approx. 3 to 4 inches from window sash ( the glass) the unit is about 14-16 inches deep. they r designed to sit flush to the sash with the upper arm( brace) touching the bottom of the sash u raised to put the unit in.and the slides on the side of the unit slide over to cover the gaps. i think u would be wise to read the instructions and follow them.3. How do you fix poor home air conditioning circulation?I would change your HVAC filter in your unit if you have not in a while. Next I would install ceiling fans in the upstairs if you have not already. Check all windows and exterior doors for drafts, a cheap way to fix that is weatherstripping. Finally, its not the cheapest route upfront, but will save you money in the long run would be to access your attic space and apply insulation on the ceiling of your third floor. .4. How common is air conditioning in Ireland?That is odd, I suppose it's mainly for enclosed malls or places such as museums that would need climate control maybe?5. is air conditioning suppose to blow out really cold air?Brand new units should drop the temperature of air it pulls through the coil by 20'F or close to that low. Meaning the 77'F room air should be somewhere between 60' and 55' supply air off of the AC. You would see a substantial drop in the air temp on a functioning AC. However make sure you installed it properly allowing for sufficient clearances for the outdoor section to vent and reject heat. It should have the proper clearances listed in the owners manual, the general clearance would likely be about 1 foot clearance from the ground so that it is not short cycling rejected heat back into the condenser section. The only other thing I can think of that I would hope you would not do is possibly turn and install the AC sideways so that the face of the AC runs vertically rather than horizontally. That would be a no go and would cause issues as well. I am assuming you do know better but in today's world people never cease to amaze me sometimes and maybe you did install it this way. All in all make sure you have proper clearances and then if you are not getting close to if not more than a 20' drop in temp I would take it back and exchange it.6. best cheapest air conditioning filters?I have used filtrete for many years. Very satisfied, but now Home Depot has changed to Honeywell and no longer carry filtrete. How does Honeywell rate compared to filtrate?7. Does running a vehicle with air conditioning on use more gas?ac runs off the engine force belt no longer the battery/besides the fact that its been interior the 90s and humid so the residing house windows might desire to be down and that will boost the drag that has effects on gasoline mileage additionally/the fee in negligible to the convenience degree/interior the outdated days the air pickups the place interior the headlight area / the airpickups now are below the hood and at windshield/those are warm spots/so which you are going to be able to desire to keep gasoline /run with the residing house windows close and the air off------in case you are able to8. What is a reasonable temperature for air conditioning?I would say it is fair to keep it between 72 and 78. Get a programmable thermostat and let it take care of the rest9. Heat pumps air conditioning?Replacing the lines may not be "required" but why leave a weak link in the chain? A clean sweep of all the old components including the lines is always a better idea.
