Air Conditioner Turns Off Before Temperature Is Reached?
There is a short in your wiring causing the power to drop going to the thermostat. The flashing is what normally happens when power is restored to the thermostat and the thermostat goes into a 'delay' mode represented visually by the flashing 'cool' signal. The problem is in the wires

Should I get my central air conditioner serviced now, or wait until next spring?
If you are regularly checking and replacing air filter, and most importantly if it is working then there is no reason to call HVAC tech for maintenance, unless you know someone you can fully trust.

Are Tempstar central air units any good? My installer is recommending a R2A3 unit.
that unit is a good unit but there is one problem. It uses a refrigerant called R-22 and that refrigerant will not be available many more years.I would not let anyone install any new unit unless it used the newer freons such as r- 410a or other more environmentally friendly freons.
Are Portable Air Conditioners Susceptible to Mold?
It's possible if you don't regularly clean your portable ac or it's filters. Depending on how often you use it you may need to clean it at least once a month(at least your filters). This will not only help against mold, but will also help your portable air conditioner work more efficiently.
Can I run a central air conditioner when it rains?
Of course you can run your air conditioner when it rains. That is kind of stupid for someone to tell them that they can not do that especially when it is very hot outside. What is the reason for having an air conditioner anyway? We use ours all summer - rain or shine.
Should you run a dehumidifier while the central air on?
If your basement is exceptionally damp it is fine, plus you probably don't run the AC 24/7. I know I don't run it when the weather is cool for a few days. Having the dehumidifier in the basement is no problem. When the AC is not used it will keep the basement dry. I do the same thing
Can having a window open cause a house air conditioner to start burning?
No, but with a window open the air con will be less effective as it may not circulate around the home as it should
There will be another reason entirely that your motor is "burning". Best to have it looked at asap as it could be a fire hazard!
will a dehumidifier work like an airconditioner?
It will only remove moisture from the air and not heat. Less humid air may feel cooler. A thermostat will read the same temperature with or without the humidifier. Weather reporters give us a temperature and a humidex. The humidex (humidity index) is an estimate of how we perceive the combination of temperature along with the humidity in the air.
My central air conditioner unit is freezing up and then won't cool.is this caused by humidity?
It is likely that your air conditioning unit is low on freon. This causes what you refer to as 'freezing up'. I would stop running the unit and have it checked by a professional. You could do harm to the compressor if you allow it to run in this condition which would be very costly to repair
whats the average cost to replace the outside air conditioner unit?
To replace a condensing unit, depending greatly on the size, should run anywhere from around $1000 for a ton and a half unit, up to $2500 for a 5 ton unit, which represents the lower and upper size of residential equipment. Special circumstances requiring a difficult changeout will up the price. Hope this helps
can black mold grow on my central air conditioner vent?
Mold regardless of type can take up residents anywhere the conditions are moist. It can be removed with water soap and disinfect and the usual protective gears (respirator, gloves). Also remember to get lot of fresh air and seal of vent to prevent airborne mold spores from moving around the house.

What percentage of total kilowatt hours is consumed by a electric fan in a central air conditioner?
Not near enough information.
The condenser takes by far the most current, but it
cycles on & off, while the fan runs continuously.
(One would have to know the cooling load.)
The current used by the air handling fan is governed
by the ductwork it must move the air through, (varies widely from one installation to the next).
What is the average cost for replacing an air conditioner?
for a small house of 1500 sq.f its from $4000 and up to 9000 depending on the brand and installer. So if you decide to go for a new A/C put some efforts in finding a good reliable HVAC company. Here is how: http://www.joetheplumbernet.com/JTP_how_find1.html
How to refill Central air ?
thats a tuffie.you need a license to buy r-22,you need a set of guages,if the unit has never been serviced you may need a torch and silver solder to install a schrader valve,a vaccuum and recover unit and some leak detection equiptment.you be better off trying something simpler like kidney stone removal as it requires less equiptment
What pressures do the high and low side run at on central air conditioners?
HVAC Tech.: Your Pressures are those of a system in peak running condition. Temperature will effect them but not to much. As it warms up the head pressure will rise more rapidly than the suction side. A word of caution for what it is worth. It is ILLEGAL to access the refrigerant lines with out proper certification, BE CAREFUL!
Where can you buy a kit to charge your central air conditioner. Mine keeps freezing up so I am pretty sure I n
They don't sell kits unless you have a license. Freezing up could be caused by low refrigerant but it also could be a dirty filter or dirty coils. Check those first and fix if needed. If the filter is fine and the coils look good, you will need an HVAC tech for the refrigerant.

Why won't my Air Conditioner cool my house?
Get a thermometer and check the temperature going into the AC intake, then check the temperature at its closest exhaust vent. If the temperature is 17 to 20 degrees, the unit is doing all it can and you need to focus on insulation, drapes, windows and temperature load.
You may have to upgrade?
Do you have air conditioner in your house?
Only window units, but it's a small house, so they work pretty well. I'm in WV at the moment but grew up in SC. This is the first time I've had a house without central A/C. It's pretty common not to have A/C around here, which I find extremely strange
my air conditioner for my home blows out a strong electrical smell.
Is this a wall/window unit. I am thinking so since you said air conditioner and not central air.
The wires to your compressor may have shorted and burned up. You can buy replacement wires and replace but its hard to tell what could have cause it without looking at it.
central air conditioner?
The only time the compressor should stop running is when the thermostat's temperature is reached.
The compressor compresses the refigerant and it is sent to txv valve or orifice that greatly reduces the refigerant temperature. This how the refigerant gets so cold.
As the residence gets warmer the a/c kicks inagain and starts the whole process over again.
New central air conditioner stopped blowing cold air, help?
If the system is under a year old-then this is a warrenty issue. You can check the circuit breakers to ensure they did not trip, and make sure your thermostat batteries, (if it has them) are not low or dead. Other then that, anything you do could void your warrenty-call the installing contractor or the seller and let them fix it under warrenty.
Question about Central Air Conditioners? See details?
If you turned the breaker on, maybe the installers put a disconnect on the outside of the house by the unit. Make sure it is turned on. Turn the t-stat to cool and fan auto and turn it down. I would think they ran the unit to try it out after they finished the installation. Hope this helps! Good luck!.
do portable air conditioners work?
they are rather weak. most of them are not strong enough to cool off an entire apartment. likely you will have to close the bathroom door, bedroom doors etc, biggest thing to make sure of is that there are no leaks (no open windows, no open door cracks, no where for hot air to enter and cool air to escape
about central air conditioner size?
You want it to cycle that way.The minutes you stated are very good and normal.If it were running continuously and not shutting off,that would be a sign of trouble.
If you are going to replace it,look into a 3 ton 14 SEER Goodman.
They have excellent warranties and are extremely competitively priced compared to other brands.
What size central air conditioner needed for a 1400 sqft house?
Hi Robert, Properly sizing an air-conditioner is very important. In most of the country there is a rule of thumb that you would need one ton for every 500 to 700 square feet. There are other variables such as insulation, ductwork, and windows. Ultimately the decision should be made by a qualified contractor. If you have any other related questions please let me know
Air conditioner does not recycle during the night.
get a fancy thermostat that has a humidity setting.
I got a new carrier ac/heat pump this year, it came with a carrier tp-prh-a thermostat. it has a humidity setting. If the temp is satisfied but the humidity rises it will run the ac and set the inside fan to a low speed to take the humidity out of the air.
What will save more money with the air conditioner.
in case you keep your temperature above 75 and use a fan to entice the air by potential of the domicile with the appropriate, that can assist keep the bill down. keep the sunlight and and the doorways closed. if you're cooling one room, the same window unit is more desirable ideal.

A/C can run all year if it's set up to run in cold weather. If the compressor has a heater inside it or heat tape around the bottom of the compressor. The oil needs to be warm or it might hurt the compressor.
The oil is inside the compressor. Hope this helps you.
My home central air conditioner turns it self on while the montier is on a off mode.
Is it the a/c or just the fan?
As you may know that the fan for heat comes on by a thermostat built into the unit.
So if your attic is very hot, the heat may trigger that fan to come on thinking that the heater is on and the plenum is hot enough and the fan runs.
Â Why does it take my air conditioner many hours to cool off again, after I turn it up, and turn it back down again?
Yes yes your are unless you know how to use a multimeter to check voltages an capacitor an amp draw of compressor.Â An gauges to check refrigerant.
From what you say sounds like possible your compressor isn't kicking in all the time hence the hot air probably cause because you air handler is in the attic.
Should my attic fan still come on when my central air is on ?
Yes it should come on if the thermostat tells it to come on. Most attic fans these days have a built in thermostat that controls only the attic fan it is attached to. It would have nothing to do with your central air conditioner. Remember that heat rises and it may get hotter quicker in your attic than in your main living areas
how the i fix the fan on my central Air conditioner?
Those motors go bad and they are not the easiest thing to replace due to the way it is mounted inside the handler. I sold quite a few of those motors to customers when I worked at WW Grainger. Im sorry to say, you probably be best off to call the maintenance guy
