Our air conditioning vents blow out cold air, but the air conditioner keeps running and the temperature in the house goes up. For example, we will set the thermostat at 78 and the temperature will read 80. We have a Trane unit that is four years old and, until a couple of weeks ago, worked fine. We had the coil replaced this week and that did not resolve the problem. Any idea what the problem could be?

There's a good chance that the unit is just too small for your house. Or that the vents and filters are clogged. Or a combination of both. Check your filters, and get the ducts cleaned. See if that helps.

Do you have a regular service contract with the dealer? If not it might be a good idea to get one. Ours gives us two inspections per year, one for the A/C and the other for heating.

We have a service contract and just had the A/C serviced in May. I do not think the tech checked the ducts when he was here so I will ask about that when I call him back next week. Could a faulty thermostat be the problem?

As Padgett pointed out, it is important to change the filters often.

A good rule of thumb told to me by the AC guy was to change your filter every time you get your utility bill (once a month).

Also, unless you're certain your unit can handle it, don't use those super allergen-type filters....some are too dense and tax the system too much.

Did they check your thermostat when the coil was replaced? I had one go in a car once and the AC went bonkers.

Are all of the coils clean? You said you had coils replaced. Inside? Outside? Both?

yes, it could be that the thermostat is faulty. Get him to check it out too.
Good luck!!

How hot is it outside? Humid?

It has been in the low 90's and humid (we live in FL).

Could your unit be freezing up?
