Central Air not keeping up. Questions.
We have two American Standard units which are 5 years old, the larger is for upstairs. I don't recall either having an issue keeping the house at the designated temperature before. I realize the system is not designed to handle to hottest days, but it should be able to handle the normal hot days, right?
I've noticed that if I set it at 73 when I leave the house it will be 76 downstairs when I get home at 7:00 pm. DH tells me it is running constantly. It seems like we have to turn the AC way up upstairs to get the downstairs cool. I don't think the air coming out downstairs feels that cold. I guess I could use a cooking thermometer to see if there is a difference in temp between the upstairs air and downstairs air at the register.
So, do you think the AC should be able to keep the house in the low 70s when it is 80-85 out? How often do these systems need to be charged? Pretty much the only thing we've done in 5 years was cover the units and turn them off every winter. Thanks.
