Maine listings come from the Efficiency Maine Residential Registered Vendor locator, filtered to the Heat Pumps service, distance “any,” ZIP 04101, on 3 November 2026. The locator requires a ZIP. That search returned vendors as far as a few hundred miles from Portland, including some with mailing addresses in neighboring states. Efficiency Maine says registered vendors are independent of the program and that it does not endorse a provider. Installer emails shown in the locator are not republished.
Questions
How many heat pump installers does ElectrifyRadar list in Maine?
590 records, checked 2026-11-03, from the Efficiency Maine Residential Registered Vendor locator (the Heat Pumps service, distance any, ZIP 04101). On this state page: 584 labeled Ownership: unverified, 5 independent, 0 PE or platform-owned, 1 franchise. These are label counts. Unverified means no documented parent was matched and no positive independent evidence was recorded.
How do I check that an installer is on the official Maine list?
Search the company on the Efficiency Maine vendor locator. ElectrifyRadar is a copy of that public file, checked 2026-11-03. The program page is the record that decides approval.
What does Manual J mean on these listings?
Manual J is the Air Conditioning Contractors of America procedure for estimating a home’s heating and cooling load. The Maine source file does not say whether an installer performed one, so every listing here says Manual J is not in the source. See the Manual J guide.
What is the difference between unverified, PE or platform-owned, and franchise?
PE or platform-owned and Franchise appear only when the business name matches a documented list, and the profile links that source. Everyone else is Ownership: unverified. Read how ownership labels are assigned.
How do I get a heat pump rebate in Maine?
Efficiency Maine’s residential heat pump rebates page, checked 2026-11-03, lists per outdoor-unit amounts of $3,000 (low income), $2,000 (moderate), and $1,000 (any income), with lifetime caps, and requires a Residential Registered Vendor.
