MarkECIN, your posts are helpful and I didn't mean to imply that your installer was not reputable. Many of us are following these Geo Thermal threads because we are considering using them in the future. I'm interested in the cost savings and payback period, and good and bad stories. I believe these posts help all of us.
Thank you for your input as well Ted.
As for me, I do not aerate and have no plans to at this point. When we eventually build our house I plan on using a geo thermal system as air conditioning in the summer. It gets quite hot at our place in northern California during the summer months. I don't know whether an aeration system would cause issues with a geo thermal system at our place or not. Ted is one of our top experts when it comes to aeration systems so I'd be inclined to believe any input that he has on the subject.
