Heatmizer

A 2025 customer said Bob and the Heatmizer team insulated their attics and knee walls, getting inside the walls from outside without creating any mess or sheetrock work in the house, and installed heat pumps. Heatmizer says it has been in business 15 years, and its own site lists service towns including Acton, Biddeford, Kennebunk and Saco. In 2025, a customer said they hired Heatmizer to install mini splits and insulate a large home they described as 18 hundred years old. A 2025 customer said Bob Frechette's staff walked them through the Efficiency Maine rebates program and that the technicians were prompt and very neat. A 2025 customer said Heatmizer knew the Maine Efficiency rebates and that the price was right. In 2021, a HomeAdvisor customer said the company did a large amount of work over 3 days, covering 1000+ square feet of their home renovation with closed-cell and HD cellulose products. In 2019, a customer said Bob Frechette did an energy audit on their 1970 mobile home before a remodel; they had Heatmizer spray foam and insulate after gutting it, and he installed a Mitsubishi heat pump. In 2017, a customer who bought a 3 season camp said Bob personally completed or oversaw the insulation project, from the energy audit to the rebate forms. A 2022 Reddit commenter on r/Maine wrote, "He did my house and cut everything more than half." In 2019, a customer who hired Heat Mizer for an energy assessment audit said they did not bring the thermal camera, and that the final report included pictures of an attic access taken with a thermal camera even though, the customer wrote, no camera was used. That customer did not feel they received an adequate energy audit.
