A July 2026 customer says Jeff at Bigfoot HVAC listened to their heating and cooling requirements, offered several solutions, and gave the most competitive of three quotes. They describe mini-split work that complemented two existing systems and fit the home’s interior and exterior. When their usual electrician could not arrange the associated work quickly, Jeff engaged an electrician to finish that part at a price consistent with their separate electrical quote. Bigfoot describes itself as a veteran-owned residential HVAC business in Belmont serving New Hampshire’s Lakes Region. Owner Jeff Miller says he started it in 2020 after twenty years as an HVAC technician and installer in New Hampshire and six years as a lead aircraft mechanic in the Air Force. He says he is the company’s only technician. The website advertises heating systems, boilers, water heaters, central air, ductless mini-splits and after-hours emergency service. Customers describe both replacements and repairs. In a February 2026 review, one says Jeff replaced a 35-year-old propane boiler and indirect-fired water heater with a wall-hung combination unit in a working space only four feet high. A January 2026 customer says another company had recommended replacing their furnace; Jeff explained several possible causes, said the furnace itself was fine, and solved the problem after two trial-and-error repairs. A February 2026 reviewer describes him diagnosing and fixing a boiler problem in below-zero temperatures after another service had struggled with the HVAC issue for months. On Reddit in May 2026, a Lakes Region commenter reported that Bigfoot had installed a gas furnace for them in January and charged less than other companies nearby. The commenter recommended Jeff as honest and dependable while explicitly expressing uncertainty about whether he would travel to Milford. Communication also draws praise. A July 2026 Google reviewer says Jeff replied promptly to texts, sent an arrival update on the service day, and answered their questions fully about mini-split cleaning and checks. In a July 2023 review, a customer describes ductless mini-splits installed in three rooms with a heat pump outside, clear costs, cleanup and explanations of operation and maintenance. Google lists a five-star average from 42 ratings; HomeAdvisor lists 4.9 stars from 25, and Thumbtack lists five stars from 10.
“Bigfoot HVAC just installed a new gas furnace for me in January. Jeff, the owner is honest and dependable and knows what he is doing.”
Joining the chorus of happy customers to praise the work and customer engagement by Jeff and Bigfoot HVAC. After a Google search of HVAC companies in our area, we sought out a free consultation with Bigfoot to address heating and cooling requirements in our new home. We solicited the obligatory three quotes. Unlike other companies who seemed to be selling their project/product and their (one) idea for a solution, Jeff had not only the most competitive quote, but he also actually listened to our requirements and gave us creative solutions based on his expertise and experience, finding the most efficient way to meet our needs. Jeff was easy to work with, with exceptional communication and professionalism throughout. The work looks as elegant and finished as mini-split ducking can be, complementing two existing systems and matching our home on the outside and integrating well into our interior spaces. When we could not quickly arrange for associated electrical work with our usual electrician, Jeff was able toengage an electrician to complete the work, and at a price that was consistent with the quote we had received for the electrical work separately. Going this extra mile was clearly just another part of working with Jeff and Bigfoot. Highly recommended; we will use Jeff for all our future HVAC/heating/cooling new requirements and maintenance.
I Saw bigfoot signs, so I looked them up. I Saw jeff worked on aircraft in the military, so it made me think he does not cut corners. Next he is working for himself, this made me think he is a technician who can diagnose problems vs a part replacing mechanic. Every time I texted him he responded promptly, also he texted me the day of service for when I should expect him. I needed someone to clean and check my mini splits. Price was fair, questions answered fully. Definitely the company I plan on using in the future.
Jeff has been my technician for several years. Every time I have an issue he always responds to my calls and quickly resolves the issue. Recently I had an issue with a house I was watching, of course on the weekend un single digit temperatures. Jeff came out and again quickly resolved the issue. I can't say enough about Jeff and his company. You will not be disappointed.
Jeff is amazing. We have had an on-going problem with our HVAC for months that was not being fixed by another repair service. We were referred to Jeff by a friend. Jeff came immediately when our boiler was not working in below zero temperature. He was able to diagnose and fix the problem quickly and it has been running great ever since. The pricing was very reasonable and the service was great! Thank you Jeff!
Reasonable prices. Fixed our boiler in time for our inspection. Defiantly recommend.
