Bigfoot HVAC LLC

The story that keeps repeating in Bigfoot HVAC's reviews is the one where somebody else already got it wrong. In January 2026 a homeowner wrote that another company had taken over $1,000 to clean their furnace and then told them to replace it, and that two more shops quoted three to four weeks just for a diagnosis; Jeff Miller came out quickly, didn't try to upsell, said the furnace itself was fine, and after two rounds of trial and error had the real problem solved. A week earlier, a customer whose boiler had been serviced badly by another outfit in November called Bigfoot and was fitted in the same day. In the field he is the whole company. A 2023 reviewer called him 'a one man show', and the reviews read that way — the same first name on every job, from the estimate to the walkthrough of how the thing works, with a 2023 customer noting Erin in the office keeping schedules straight. He is also, by his customers' account, a veteran: a July 2026 reviewer picked him partly because 'jeff worked on aircraft in the military, so it made me think he does not cut corners', and a 2024 reviewer summed the business up as 'Reliable, honest, local, veteran-owned.' The work covers the residential heating and cooling spread. In February 2026 a customer described a 35-year-old propane boiler and indirect-fired water heater coming out and a modern wall-hung combi unit going in, designed and installed inside a four-foot-high working space. A July 2023 review covers ductless mini-splits in three rooms plus a heat pump out back — clear about costs, no upsell, mess cleaned up. Water heater swaps and furnace service fill in the rest. Availability is the other thread. One customer's heat failed at 8:30 at night in single-digit cold and most shops were closed for the evening; Bigfoot came out. Another had a weekend failure, also in single digits, at a house they were minding. A third got a fix the day before Christmas. Google puts him at 5.0 across 42 ratings, HomeAdvisor at 4.9 across 25 and Thumbtack at 5.0 across 10 — the platforms agree with each other and with what people actually wrote, 59 reviews since 2020 with nothing negative among them. Price comes up often and favourably: 'incredibly fair', 'very reasonable', 'a good price'. A Lakes Region commenter on r/newhampshire said in May 2026 that a January gas furnace install cost less than other companies in the area. Two practical notes. He is one technician, so capacity is one person's day. And that same commenter wondered aloud whether he would travel as far as Milford — if you are outside the Lakes Region, ask before you plan around him. For a heating failure near his Belmont base, or for a second opinion after someone else has told you to replace the whole system, this is a straightforward call.
