Penobscot Home Performance is a home energy and insulation business. On its BBB profile the company describes itself as offering energy evaluations, infrared scanning, air sealing, insulation and other energy-efficiency retrofits, plus consulting and testing on new construction. A greenmainehomes.com article has quoted Paul Shepherd, co-owner of Penobscot Home Performance, which it describes as assessing homes in Down East and Central Maine. Its BBB grade is A+. A 2023 customer said they used the Efficiency Maine rebate program to have PHP add attic blown-in insulation and basement panel insulation, and that the crew was considerate and clean with their traffic through the house. A 2022 customer said they hired PHP for an energy audit, new attic insulation and bathroom vents, all required for the Efficiency Maine rebate. That customer said Matt was responsive to email, which made the initial consult, scheduling and rebate paperwork easy.
“says Paul Shepherd, co-owner of Penobscot Home Performance , which assesses homes in Down East and Central Maine.”
We used the Efficiency Maine rebate program and had PHP add attic blown-in insulation and basement panel insulation. All the work was done efficiently. The crew was very considerate and clean with their necessary traffic through our house. We heartily recommend this business.
We contracted PHP to improve the efficiency of our home -- energy audit, new insulation in the attic, bathroom vents. All required for the Efficiency Maine rebate. Matt and his team were a delight to work with. Matt is really responsive to email, which made the initial consult, scheduling, and paperwork for the rebate really easy. I've recommended PHP to friends and family and we'll try to get back on their schedule to do some work on our basement next year. Thanks Matt!
