Struggling A/C advice
Let me give you then rundown of my situation and advice given to me and then tell me what you all think
House has a 12 year old a/c unit. ive only lived in the house a month so I don't know its history.
The unit is a 2 ton Goodman central heat a/c
The house is a single level 1050 sq foot house with a large crawl space, no whirly's or electric vent fans
When I leave in the morning I put the thermostat up to around 78 and when I get home I turn it down to 72. When I go to bed I like it around 69.
But it is struggling I can tell to keep me cool. When I get home its always around 80. In the evening it keeps around 74-76 degrees and when i go to bed it takes around 3-4 hours to get the temp to 69 degrees.
I had a service guy come out and check the unit. He added 1 pound of freon and said the coils were clean.
He made a big to do over me not having any attic whirlys or electric fans up there
He also said this is as good as it's going to get and that replacing my compressor would do me no good. The only way my house is going to get cooler is by addding attic ventiliation, keeping the thermostat at 72 all day so that the unit doesnt have to work so hard when I get home, and eventually, get a new unit.
But this is my problem:
I just moved from a 1500 sq foot house that a smaller crawlspace and no whirly's or electric fan either.
It had a much smaller a/c unit, it was a carrier, and the house was 500 sq ft bigger than the only I have now.
This unit had no problem keeping my house as cool as I wanted it and kept up with the temp change from when I got home and turned the a/c down.
And surely the unit did not work this bad for the past 12 years or they would have complained.
So, what should I do? It is under warranty with my home for a year but the company servicing the warranty told me the same thing. Putting a new compressor will do no good. Only adding vents will help. I just don't buy that this is as good as this unit has ever performed. And if the performance has decreased, what could it be the result of ? Short of draft leaks from windows and doors. The duct work is in good shape too
