Reviews From Southern NH Homeowners
A.J. LeBlanc Heating was not only professional, but the installers were neat, clean and concerned with protecting my carpets and floors. They did a great job of installing my mini-split system and took the time to explain everything to me.
Darlene ParentDuctless Mini Split customerTechnicians for servicing our oil burner and installing the mini splits were very knowledgeable and courteous.
Paula MorinDuctless Mini Split customerWe had a new whole house a/c installed. The technicians were very competent and had the unit working for that evening of the first day of the two-day installation process. That made my wife extremely happy so that made me very happy as well. We are very pleased with the service and the installation.
