Question : If it’s not dirty coils that’s causing my central AC to cool poorly, what is it?
I have a new condenser unit outside. And I was told the coils in the unit in my attic are very clean. Matter of fact, last AC guys out to my house (who I didn’t like from day 1 but came through home warranty co) insist the unit(s) are all operating as they should be. But my house is cooling poorly. Last night, I got it down to 79 but if I try to do that during the day … it’s a no go. I’m in Houston, where it’s been 91-95 but my house has never cooled this poorly and it’s been this hot before! Matter of fact, during the day, even if I set it to 77, I can’t get it below 80-81. It used to wok better than this, for sure. Oh … and it takes about 2 hours to go from 83 to 81; at least it did the other day.

What could be the prob?

The condenser unit, btw, is a 12 seer. The old one was 10. But the new one is about 5/8 the size of the old one. Could that be part of the prob?

Oh, and I’ve been getting an INTERMITTENT drip into the pan under my attic unit.

There’s definitely something wrong. Have them check it again and again until you are satisfied. If it’s a new unit there should also be a warranty. Make them come and check it out. Maybe there’s a freon leak…they can test it to see. Also, if it’s really hot out your unit will try and try to get it cooler but it’ll still have to work a bit. Have them check it again for a leak, especially it should not be dripping water
