Lester HVAC LLC

On 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 the heat running again within the hour. That is the story customers of Lester HVAC keep telling — the call that gets picked up when it is freezing, boiling, or a holiday. Dave runs the company and is the name in nearly every account. In June 2026 an air conditioner quit right before a heat wave; a text brought him out the same day, and the fault turned out to be mice that had chewed through wiring in some awkward spots. In June 2025 a customer had already called three companies before Dave came out the next day, found the problem in minutes and fixed it that same day for a price they thought fair. In July 2025, across some of the hottest days Boston had seen, he came out twice in three days. Installations get the same attention. A multi-room mini-split went in during October 2024 after a good quote; another was added to a second floor in April 2025; in June 2026 a couple had one installed by a crew carrying both HVAC and electrical trades. A July 2026 customer whose heating and cooling system the crew had replaced ran into trouble with the old ductwork afterwards, and Dave came back to resolve it. Another that month pointed out that the company understands how the rebate programmes work. Commercial calls come through as well: a shop with no air conditioning in October 2024 had someone there within a couple of hours. The written record is short and recent — 23 accounts since 2024, all five stars — and a 2025 customer described Dave as very busy even as he made time for them. For a no-heat or no-cool emergency, a mini-split installation, or a system swap where rebates are in play, this is a small outfit that picks up the phone. Ask how his schedule looks when you call, and settle the rebate paperwork before the installation date is set.
