I have asthma and it had been so severe I was out of work for a month. My doctor suggested we have our ductwork checked. I called Contra Costa Climate Control and found out that our air ducts were filthy and our old system was inefficient. They replaced and relocated our system to the attic, installed new ductwork and added the Clean Effects filter. It?s been amazing?I?ve had a 360-degree turnaround in my health!
