Take It From Our Customers

Aeroseal Installation in Hudson, MA 01749

“A big thank you to Jake and Tyler who Aerosealed ductwork in my home today. I am anxious about having contractors in my home, but there was no need with these guys. It was a stellar experience in every way and I would recommend your company without hesitation. Kudos, Jake and Tyler!”
- Rhonda P.

Boiler Repair in Hudson, MA 01749

“I would like to acknowledge the extraordinary service I received on Sept 30th from Basnett technician Leo. The original request was to service the boiler & ensure it was in proper working order for the winter which he did. Upon inspection, Leo identified an issue that would require a replacement part. He obtained the part & installed it within a day. Because of Leo’s expertise, dedication & commitment, I was only out of heat/hot water for a few hours. Thanks to Leo for his professionalism & excellent customer service”

Heating Installation in Harvard, MA 01451

“A shout out to Paul Lizotte and the Basnet Crew on an outstanding design and installation of a complicated whole house heat and hot water system. The new 3 zone system with Viessmann Boiler, Vitocell Indirect Water Heater, Purmo Eurostyle wall mounted radiators and Runtal baseboard radiators is really efficient, and quiet. Workmanship was excellent, and we appreciated the care taken in our old house. Thank you very much.”
