I recently bought a home and would like to put in ac for the first floor and basement as well as some type of air filtration system (which I'm learning more about in the air quality forum). I'm just wondering if anyone has any good recommendations for me as far as someone to put the system in? I am going to get an estimate from House of Heat in Oak Park as well as Unique in Elmhurst but when I talked to them on the phone I didn't feel like they knew very much about the air filtration systems out there. I live in Oak Park which is on the West side of Chicago.
thank you very much
