We had a new air conditioning system installed in our home 2 years ago. It has never really provided us with a comfortable air conditioned environment.
The ac system can produce allot of cold air very quickly, but shuts down within 10 minutes of starting, staying off for 15 minutes, then starting again. The result is a cold, clammy feeling house.
The HVAC company says they did a manual J and manual D before sizing the unit for our 3,200 sq. ft. ranch style home and came up with 2 - 3 Ton units. One cools the bedroom wing and the other takes care of the LR/DR/Kitchen/Den.
I'm starting to think that the system is over sized and is unable to dehumidify the air because it doesn't run for very long. The RH outside is about 85% with a daytime high of around 80F. The inside RH is about 65%.
Is there a guide to the correct RH in a house (summer)? Does it depend on outside RH and temperature?
