Home central air conditioner problem?

Question

For some reason within the last week my home AC is turning on less frequently. It'll come on at random times but when it does the air is not as cold as it used to be. Usually it's 70 in here but right now the thermostat is showing 80 and it rises during the day. This AC is 2 years old.

I've tried resetting the breakers and playing with the thermostat controls but that didn't work. I live in a condo complex but the AC isn't covered and it's quite expensive to have a AC repairman come out.

Any advice on anything else I can do or check myself?

Answer 1

have you changed the filters lately?

should be changed monthly.

if the filter is dirty the unit might be froze up and it can't cool.

Answer 2

Does your AC have an outside unit (compressor and fan).  If so check and make sure that dust, grass clippings, ect haven't clogged the fins on the coils in that unit.  Also, make sure it is running when the inside unit is.

If they are clogged or very dirty you can turn off the power to it and spray it with water hose but be careful not to bend the fins ie. don't use a pressure washer.

Answer 3

You might check the AC filter, if it's clogged the unit won't cool as well as it should.  If you can take the cover off the thermostat control, look for dust or if it's broken.  The breakers should not have anything to do with your problem.

Answer 4

She could be froze up but usually runs non stop when this happens.Check and change your filter as needed..Turn the fan to on and the "heat - cool" to off for 30 minutes.Then put it back to 73,cool,and fan to auto.If she was froze you will get some cooling now.There are many other reasons why it may not be working besides being froze up though.None of which you can realistically check yourself and will have to call for service.
