I had an unfortunate leak in my ceiling that was near a chandelier. I called Basnett and they were extremely responsive in the very early hours of the morning. They were able to send a technician (Leo) promptly and he was incredible! He explained the situation, the possible outcomes, and what his professional recommendation was. He could not have been more efficient. I would use Basnett again for Leo's services alone. Quality representative!

Basnett installed our new high efficiency boiler and SuperStor tank a little over a week ago and the quality of work surpassed my expectations. I had 4 other companies quote the job and was not impressed with any of them. Tony always took my calls prior to the install and amazing to work with. I have recommended Basnett to several of our friends who are looking to get a new boiler system or split air system.

Wayne and Joe were outstanding! Please take to talk with and made sure EVERYTHING was right, complete and clean!! The process of scheduling and staying informed about travel and arrival status was outstanding (including the text message with bio and picture of the technician). We found our new service provider for HVAC and plumbing.
