Bob Sylvester
Knowledgeable and Efficient Technician
The technician, Alex and his partner, arrived during the given time window. He seemed very knowledgeable. I had a new Carrier HVAC system installed. He had a hard job as the HVAC system had to be installed in an unfinished basement with several very steep steps. He was efficient and quick. He took time after the installation to answer my questions about the HVAC and the new digital thermostat.
Ann Porter
Five stars for Bel-O
Jim was excellent and did a great job. He was a real pleasure. John came out a few days later to measure for a tankless water heater and came up with a very good offer. Thanks Bel-O.
New edit: 2/27/2025 Evan and Jim returned today to install a new tankless water heater. They did a great job installing and explaining how it works. They also cleaned up perfectly when they finished. Five stars for Bel-O.

Evan was wonderful with assistance for both plumbing inspection and fixing small issues as well as cleaning my duct work and replacing a few boots on my floor. Very polite, kind, and professional.
Angie Baron
Smooth Installation Experience
Everything, from the initial call for an estimate to the follow-up visit to adjust settings, went great. I interacted with a total of (maybe) five people, but they were all friendly and helpful. We had a water softener installed. They were reasonably priced for this service (I compared a few local companies). The installation went quickly and very smoothly. When we had questions after the install, I called and someone came by to check on things, explain things, and let us know everything was working (but how to adjust things if we wanted).
Jenn Mench
Solid Team
I’m impressed with Bel-O. Ryan was very cooperative on our initial phone call. Sabrina couldn’t have been more pleasant and prompt in getting me answers to my questions, and John is clearly a very skilled professional at his craft. They have a solid team, thanks for the service.
