Hannon HVAC LLC describes itself on Thumbtack as providing sales, service, and installation for boilers, furnaces, central air conditioners, heat pumps, mini splits, on demand water heaters, tank water heaters, and oil tanks, and says it works on oil, propane, and natural gas systems. A 2024 review places the company in Hooksett, NH. In that 2024 review, a customer who had used the company twice said it did a routine furnace clean and a repair on their central air system, with service during a heatwave that came more quickly than expected and at a reasonable price. In a 2023 Thumbtack review, a customer said he took the time to explain the age of their 30-year-old a/c unit, and when a new unit was needed he had them set up and running in a week. In a 2022 review, a first-time customer whose heating system started leaking said Brad returned the call quickly, helped troubleshoot, and shuffled his team's schedule to get the system, which needed a large repair, back up and running. A 2022 Thumbtack reviewer said Brad came to see their heating system the same day as the request, had the job complete within a week, and left the basement clean of old debris. A 2022 Google reviewer who got quotes from three other companies for mini split heat pumps said Hannon HVAC worked within their budget and fit the install in before the 90 degree weather arrived. In another 2022 review, a customer said he was at the house within the hour of being contacted and fixed the issue with their AC. The company's New Hampshire HVAC licence, MBE2001246, held by Hannon HVAC LLC, is expired on the state registry, which lists it as lapsed.

Shout out to Hannon HVAC LLC in Hooksett, NH! I have now used this company twice. Once for a routine furnace clean and today for a repair on my central air system. In this heatwave, I did not expect service so quickly and am very grateful! Professional service at a reasonable price! I highly recommend!
Hannon HVAC came to my rescue this summer, twice. The first time it was an easy fix but he spent the time to educate me on the age of my a/c unit (30 years) and how I would most likely need a new unit within a year. Well, the time ended up being sooner rather than later. Do to the age of my unit I needed a new one. He had me set up and running in a week. Thank you!
My heating system started leaking 3 days before my scheduled cleaning appointment with Hannon HVAC. Even though I was a first-time customer, Brad reached returned my call quickly and helped me troubleshoot this issue. In the end, the system needed a large repair. Brad shuffled his team's schedule and got everything back up and running smoothly. Hannon HVAC (Brad and Team) are both professional and responsive. I highly recommend them for all your HVAC needs.
Brad was great! Came to see my heating system same day as my request. Had the job complete within a week. Left my basement clean of any old debris. My new system is amazing!
