Gold Star Heating and Cooling

Pulling a 1990s heat pump out and putting a modern system in turned into a hunt through the woodwork — line-sets rerun, tubing adapted — and the 2024 homeowner who lived through it came out happy. Gold Star Heating and Cooling does that kind of work on the South Shore and, by its own account, across Massachusetts: installs, repairs and maintenance, ductless and heat pump systems, indoor air quality equipment and water heaters. Its site lists Mass Save certification and free estimates. Frank and Anthony are the two names that recur through the reviews. They replaced a furnace for one homeowner in May 2026, and a February 2026 review says the pair service the heat and AC at a restaurant and explain both the problem and the fix each time. An August 2026 customer had an entire HVAC system swapped out and noticed how carefully the equipment was moved through the house, with everything left clean and working. A central AC unit went in for a May 2026 customer at what they called a reasonable price; a May 2026 reviewer credited Richy with communicating clearly and delivering exactly what was asked for; a September 2026 customer watched the crew walk the area several times at the end to check the work. Older accounts run the same way. In a 2025 review, a homeowner recalled an A/C failure during the hottest week of the previous summer that ended with two new condensers and air handlers after Frank went through the options, and a 2024 reviewer described the crew steering her 90-year-old mother through the Mass Save preauthorization paperwork before the work went in. The complaints to ask about are older and both sit on HomeAdvisor. A 2024 reviewer said the job on a brand-new house in Hull was dropped — two units installed, one in the attic and one in the basement — and wrote that the contact he reached told him he was no longer with the company, leaving him unsure who to ask for. A 2025 reviewer wrote that calls went unreturned while $700 of materials already paid for sat undelivered. Those two land on a 4.4-star average across 15 HomeAdvisor ratings, against 5 stars from 60 ratings on Google. For a straightforward replacement — a furnace, a central AC unit, a heat pump, or a whole system — this is a South Shore shop with a long run of homeowners describing on-time, tidy work. Get the estimate in writing, settle who your point of contact is after the crew leaves, and if you pay for materials up front, pin down the delivery date.
