I have been doing business with Airsmiths Home Performance for about five years, and it has been a great experience working with them. They recently came out and gave me a new HVAC system thru the smog rebate program. That included an air conditioning installation, heating system, new ductwork throughout the entire house, and a new water heater. It all turned out really good, and I would definitely recommend them to anybody needing a new HVAC system or water heater installation.
