Gibson 2 1/2 ton not cooling well?
Ok, so some of you oldies know that I had a Gibson 2.5 ton heatpump installed in January of 2008. It has run well with a few times that when it was really really hot (90's) outside that it wouldnt cool the house below 75. Right now, even though we have had pretty decent weather... I am still rarely getting below 71 degrees. I realize that most people are happy with that... but while I am asleep, I am not happy with that... I dont sleep well if I am not good and cool and breathingn cool air... anyways..... It shouldnt have a leak although I will toy with the idea... it has new runoffs.
The thermostat I bought came from Lowes, and the guy that installed the unit didnt like the one I bought and said that I should buy one he wanted me to buy. It is a honeywell digital for heatpumps.
Could just the thermostat be the problem?
I should also add that I have 2 return air vents and I have cut air filters to fit on top of those vents... and they are cleaned off once a month or so.... there is no where else for a filter.
(and.... the guy that installed this did so on his own time and I have felt uneasy since then about his integrity, which Is why I am questioning things now....)
I just dont think it is too unrealistic to expect to be at 68 when it is less then 80 outside.... especially with the electric bill that I pay every month.
Feel free to give me your opinions as I really do want to do things right, I just have trust issues when it comes to cold hard cash
