My husband and I built our house about 4 years ago. We had a geothermal unit installed and we haven't really had any issues with it until summer. In the summer our house has a very damp feeling- the air feels damp, our furniture feels damp, our beds feel damp, clothes, pretty much everything in the house. Mold has been growing on our walls, doors, toys(kids toys) clothes, well you get the point. Anyways, I contacted the business who installed it and they said geothermal units do that because they aren't running long enough in the summer and to either turn up my heat extremely high for a few hours while we are out of the house or to buy dehumidifiers.. I'm a little erked by this because we spent a pretty penny on this unit. I feel like this shouldn't be an issue. Anyways, I was wondering if anyone had any suggestions or related issues with this that could give me some advice. Thanks in advance!
