Pinnacle Piping and Service

Cooling that has stopped keeping up is the job Pinnacle Piping and Service keeps getting called for. A June 2026 customer had a clogged filter traced and cleaned out after the house wouldn't hold a temperature; that same month another had an old A/C system dismantled in a little over an hour; in April 2026 a new thermostat went in, with the technician walking the customer through how to use it. The company works out of 950 Dorchester Ave in Dorchester and says it has been family-owned and operated since 2003, doing HVAC design, fabrication, installation and service across Greater Boston. It also says its technicians are Local 537 certified. Ductwork comes up about as often as equipment. A May 2026 customer booked a duct and vent cleaning after noticing a decline in air quality and had it finished in two hours; an April 2026 review describes new ducts going in within an hour and the airflow improving. On Google the company sits at 4.6 stars across 10 ratings, and its BBB page carries an A+ grade with 23 years in business listed. Further back, a 2021 reviewer singled out service manager Dan for staying on top of their needs and concerns. One thing to settle before you call: the company's own site aims itself at commercial, educational, healthcare and pharmaceutical clients, while several of its Google reviewers describe work at their own homes. Ask whether your job — a seasonal tune-up, a thermostat swap, a residential duct run — is the kind they take on. If it is, this is a sensible call for straightforward cooling and duct work. Get the scope and the price in writing, and ask for licence and insurance paperwork before the crew starts.
