I’ve tried everything else except ask P-F, so….
A month or so ago, I walked upstairs at my house and found that the humidity was around 70%. The carpet and walls felt wet. Obviously, this is not normal. I figured something was wrong with the heat pump (I have two heat pumps, one for upstairs and one for downstairs— downstairs humidity is fine). I had a guy come out multiple times, and he could not find anything wrong. I thought maybe the coils were dirty in the indoor unit, but he said they looked fine. I bought a de-humidifier, and it’s working, but it has to run nearly all the time to keep the humidity at 50%. I thought maybe the thermostat was faulty, so I bought a new one, which did not help. I also had my roof inspected, even though there were no indications of a leak that I could see inside.
- The heat pump is the right size for my home.
- The refrigerant is not leaking.
- Windows are closed.
- Heat pump is not short-cycling.
Any ideas here? I keep hearing, “Well, it’s been really humid,” and that’s true, but it’s been really humid every summer for the last 8 years that I’ve lived here. Something had to have happened for this to be an issue so suddenly.
