Reviews From Southern NH Homeowners
LeBlanc Heating installed a new system 2000 boiler; water heater and a new power vent in my house. They did an excellent job removing the old system and installing the new one. The service techs were professional and the workmanship was outstanding. I am extremely pleased with how efficient the new system operates and it is so quiet it is hard to tell it is running. I chose A.J. LeBlanc Heating because of their reputation and all the positive reviews I read. They were on time for the installation and completed the work on time and as promised. I would strongly recommend A.J. LeBlanc Heating to anyone looking for a reputable company to handle their plumbing and heating needs.
