Hello I am new to the site but have done some geothermal research so not totally clueless.
I have an 1800sf home, about 750sf has a 17ft vaulted ceiling. It is built on a slab and is R3000 construction. I have a 3.5 ton Climate master with a down flow forced air duct supply. I have owned the house for 3 years. Which leads to the problems part of the question. First I will say I have no confidence in the two technicians I have had come to the house already for other reasons(long story for different post).
My present problem is yesterday the heat was 90 degrees with high humidity. The system was able to keep the temp at 73 during the day but come evening it ran for basically 4 hours and could not get below 75 degrees, finally I turned it off and opened the windows. . Also lately it doesn't seem to be lowering the humidity very much. Cooling is where the Geo is supposed to shine. Anybody have any similar experiences, thoughts or recommendations?
Btw in the winter it might easily run for 1.5 hours straight when it' s minus 30 out, but it's never run like that for cooling.
