Lester HVAC LLC

Christmas Eve, 2024: a landlord's tenants had no heat and nobody else was answering the phone. Dave Lester and his crew came out and had it running again within the hour. That call sets the tone for Lester HVAC, a Boston-area heating and cooling outfit people reach for when something has already broken. The written history is short but consistent: 23 Google reviews between September 2024 and August 2026, 5 stars across 24 ratings, with no dissenting comment among them. Two jobs come up more than any other. The first is mini-splits, single units, multi-room systems, a second-floor install, and customers mention the quote about as often as the workmanship. The second is emergencies. One homeowner texted Dave when their AC quit ahead of a heat wave this June and got a visit the same day; the fault turned out to be mice that had chewed through wiring in tight spots. In a 2025 review, another customer wrote that three companies had already looked at their AC before Dave found the problem in minutes and fixed it that day. They also replace whole heating and cooling systems and stay for the follow-on work. One customer whose system was swapped said Dave came back later to sort out trouble with the old ductwork. Condenser replacements and relocations turn up too, and a reviewer this July noted the company knew its way around rebate programs, which is worth raising if you are pricing new equipment. The operation reads as small and owner-led. Dave Lester is named in most of the reviews, usually alongside a crew customers describe as punctual, tidy, and willing to explain what they are doing. The work is not strictly residential either: a shop owner had cooling back within a couple of hours, and a landlord uses them across tenant properties. Two things to weigh before you call. Everything known about this company sits on one platform, since every star and every written comment comes from Google, so nothing independent corroborates the picture. And the written history only begins in September 2024, a thin paper trail for judging consistency over time however steady the last two years look. If you want someone who turns up when the heat or the AC quits, and especially if you are pricing a mini-split, Lester HVAC is a sensible call. Ask about rebate eligibility on any new system, and pin down the quote up front, which is the part reviewers who mentioned it were happiest about.
