Hannon Heating & Air Conditioning describes itself as an owner-operated HVAC company in Bellingham, MA since 2014 that repairs, replaces and tunes up gas and oil furnaces, boilers, central AC and ductless systems across MetroWest, with a quote before any work begins. Its site lists a service area that includes Bellingham, Franklin, Framingham, Milford, Natick and Upton, and it holds an MA HVAC license that is active on the state registry. A recent customer says the team at Hannon came right out to inspect their central AC, diagnosed the problem, ordered the parts and had it up and running again before the first company they called even called back. Another recent customer says Hannon replaced their furnace and cleaned their air conditioner, and that Paul and Dorian were on time and very professional. A third recent review says Paul is 100% trustworthy and describes fantastic communication. In a 2026 review, a customer said that when their furnace stopped working, the company came out very quickly and spent the day making sure they could get their heat back. A 2025 review said Paul has done mini-splits, a water heater and the customer's annual furnace cleanout for multiple years. In another 2025 review, a customer said the company took out their old AC system and put in a new one, and that when a controller had an issue, he replaced it and said it would not cost them anything. A 2025 reviewer said Paul serviced their furnace in December, as he had for the previous condo owners for 6 years, and later called back in 3 minutes with the information they needed instead of a chargeable service call.
Honest, reliable and masters of their trade. I found myself in a very unpleasant situation with a very well-known local HVAC company and was desperately calling other companies for help and advice. Not only did the team at Hannon answer my call, they came right out to inspect my central AC, diagnosed the problem, the cause of it, ordered the parts and had it up and running again before the first company EVEN CALLED ME BACK. The communication was fantastic and the customer service was second to none. They are, by far, the best HVAC company in the surrounding area. I highly recommend them for all of your HVAC issues and repairs.
Hannon Heating and Air Conditioning does fantastic work! I just had them replace my furnace and clean my air conditioner. Paul and Dorian were on time and very professional. In this day and age, it’s so nice to work with a company that is honest, thorough and has fair pricing. Hannon Heating and Air is my go-to for anything related to my HVAC system. I highly recommend them!
Paul at Hannon Heating and Cooling is as good as it gets. Fantastic communication, extremely friendly, and 100% trustworthy. It’s rare to find technicians this reliable and honest. Wouldn’t hesitate to call him again or recommend him to neighbors!
We had a huge issue with our furnace and it stopped working. Came out very quickly and spent the day making sure we could get our heat back. Very important with a baby in the house! Thank you!
Paul is simply the best to work with! He’s now done mini-splits, water heater, and our annual furnace cleanout for multiple years. Incredibly responsive, very fair pricing, and gets work done quickly and efficiently. Highly, highly recommended!
