Frank's Heating Service

Frank's Heating Service works out of 555 Woburn St in Tewksbury and describes itself as a residential and light-commercial heating and cooling contractor, handling furnaces, boilers, heat pumps, air conditioners and ductless mini-splits across eastern Massachusetts and southern New Hampshire. The Better Business Bureau records the business as having started on 1 January 1981. Massachusetts's state licence registry lists an active HVAC licence, 69-SM-B, held by Hillis Corp doing business as Franks Heating Service. The deepest praise is about installation work and about individual technicians by name. A homeowner replacing a whole AC and furnace system wrote in August 2025 that of four quotes, only Frank's took the time to measure the house and size the unit to it rather than swapping in the same oversized equipment, and that the electric bill dropped afterwards. Another described an unusual-shaped house with a maze of baseboards where the company mixed traditional heating with ducted and ductless heat pumps, finished within a week using several crews, and left no mess. A June 2026 customer described a next-business-day visit for a central AC failure where a junior technician's notes were reviewed by a senior technician who came back out to verify the diagnosis before any parts were ordered. Names recur across years — Chang, Craig, Greg, Justin, Tim, Ivan — which is the pattern of a stable crew rather than a rotating one. The complaints cluster around price and around installs that had to be revisited. A February 2026 reviewer says they were quoted $1,900 for a gas valve they priced at $500, declined, and found the diagnosis itself was wrong. A January 2025 reviewer whose community had all its HVAC installed by the company described the exhaust flue sagging and collecting water, blocking the pipe in a finished basement ceiling. A July 2024 customer said a replaced condenser was never tested, and the fan unit turned out to have seized. Two more reviewers, in 2024 and 2025, flagged high pricing specifically — one on a $589 thermostat swap, one warning to get everything in writing after the initial quote. The honest read is a competent installer with an experienced crew whose pricing and follow-through are the recurring sore points. If you are getting a system replaced, this is the kind of shop worth getting a quote from — and worth getting that quote itemised in writing, along with a written commitment on post-install testing and callbacks.
