SOURCE: AC unit runs inside but not outside! help

check your thermostat is it set on cooling, check your pressure switch it might be triped due to blocked condenser.

SOURCE: my central air also makes squeaky noise

All new blowers are sealed units you really can not oil them. By the time they start howling it is to late. Now some evap motros inside have two small plastic plugs on the motor. The outside one is easy to oil the inside one is blocked by the fan. Very hard to get to without pulling the fan. My suggestion calla service tech and ask for free estimate on motor service or replacement.Russ

Ac unit runs, inside blower shuts off after 2 mins, compressor continues to run, t-stat still calling for cool


My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem.

Cant keep cool


You need to check that tour filters are new. Then check that air is coming from the vents and is at least 15 degrees cooler than room temp. If no air coil is frozen, or blower motor and run cap are not working. If frozen than turn system to off and fan switch is on until you feel air through vents.
You'll need to make sure the outside unit is runing and the larger copper line is cold like a can soda. If it's cold but is freezing up, it needs to have a charge added. If its running but not cold and the fan is not running or the compressor isn't running it could have a blown capacitor. If its not running at all check. the circuit breakers and reset them. And a good idea to keep the outside unit washed with water,and that it is clear of weeds and stuff.

It is freezing inside, and it is not cooling properly


Welcome to FixYa,
Check the Following
Is your filter clean? Look and the evaporator in the inside unit. Is it frosted up? Do you have condensation water in the pan? Go to the outside unit and feel the air coming out of the fan. Is it warm? Now feel the 2 copper pipes coming out of the unit. Is the small one warm or hot? Is the larger one cool ? Is there moisture on it?
Air conditioner runs but doesn't cool at all
If the airflow is good and the air coming out is not cold, your home air conditioning problem may be a temporary problem - your coils may have frozen. Turn the unit off for an hour to let them thaw, then try again. If cold air is now present, freezing coils were the problem; if the problem recurs soon after turning on, you may need to replace the coils. Again, call a pro. If you have ceiling vents in upstairs rooms and the air flowing from them is consistently warm, you probably have leaky or poorly insulated ductwork in your attic. See my Attic ceiling insulation page for more information on insulating ductwork that runs through attics.
Another likely home air conditioning problem if you have good airflow but no cooling is that thebreaker to the outside unit is shut off, which, depending on the installation, can either cause the air conditioning system to not run at all, or to appear to be running but not provide any cooling. If you can hear the compressor fan running outside, the breaker is on, but if the outside unit is silent the outside breaker may be off. If switching it on does not solve the problem, look for the high pressure cut outon the condenser and try resetting that.

The fan is running and blowing cool air out of the unit but there is no air coming through the vents, what are the possible problems? (Lennox Elite series)


The unit could possibly have a frozen indoor coil. Turn ac to off...and fan switch to on...wait 45 minutes and see if air flow improves. Check for dirty filter which can lead to freeze up. Low on freon is also a possibility.

Is your condensing unit located in a well ventilated area and have an ample space, atleast a foot, from the rooftop flooring? Just make a check that free flowing outside air properly ventilates the condensing unit specially on high ambient temperatures. Hope this would solve your problem
