Dave is an air conditioning contractor. He specializes in the residential market, and tries to stay on top of the latest technologies and solutions available for the entire HVAC system. He prides himself on not being a parts swapper.
Lately he has been reading everything he can about IAQ in order to understand the impact it has on the HVAC system as a whole; he even went to a few seminars during the winter. Little did Dave suspect that he would be able to put the information into practice so soon.
