Today certified solar heating and air conditioning was in the concord area performing a attic insulation blow in. We ensured that electrical was covered with can light covers, installed insulation rulers to ensure that we installed 22” in all areas that was possible. After blow in was completed we ensured that the platform was cleared and the home was spotless. With the new installation of insulation the clients will be able to regulate the temps in their home a lot easier this summer season

In the concord area giving an estimate on re insulating an attic! Our customer home had just about nothing in his attic as far as insulation goes. This can cause multiple issues for you and your system! Most of all, in can cost you to spend more money that you could be saving! Give our company a call to see if you need more insulation in your attic! We will be happy to assist and help!
