Thermostat Replacement in Concord, MA, 01742

“Showed up quickly. Professional and courteous. Diagnosed that I needed a new thermostat and advised to get the same model online and install it myself since the new thermostats are incompatible with the 10 year old wireless interface on the furnace. This would be the cheapest fix.”

Indoor Air Quality Installation in Clinton, MA 01510

“Sales manager Andre Chaves checked all areas of concern in our home. Both my wife Joan and I were more than satisfied with hearing of a cure to our problem using an ERV ventilating system or dehumidifier system. Although I have some concerns about the installation and venting over the garage door are coming up, I believe this can be accomplished with no problem. Both Mr. Chaves and their HVAC Tech were very professional.”
