What Maine Homeowners Say

Real reviews from real customers across Southern Maine.

"The process was pleasant from start to finish. When cleanup was complete, it was like no one had ever been there. Working through the rebate paperwork was some of the easiest interactions I've had. I cannot recommend Horizon Homes enough."

"An Efficiency Maine inspector said 'Oh yeah, Horizon, their work is always great.' I'm a first-time homeowner who relies heavily on online reviews, let me add to the five-star pile. Horizon Homes was the right decision for us."

Common Questions

Frequently Asked Questions

Everything you need to know about our free home energy assessment.

Yes, 100% free with no strings attached. We don't charge for the assessment and there's absolutely no obligation to move forward with any work. Our goal is to give you the information you need to make smart decisions about your home's energy performance. Learn more: The True Cost of Doing Nothing About Home Energy.
A traditional home energy audit uses a blower door, thermal camera, and combustion analyzer to produce a written diagnostic report. Our free energy assessment is a visual walkthrough by a certified advisor focused on giving you a prioritized plan with real pricing and Efficiency Maine rebates deducted upfront. We still use blower door testing and thermal imaging, but as part of the actual work: a baseline test at the start of the job, thermal imaging to target specific leaks while we seal them, and a verification test at the end to prove the improvement. You get the benefit of the testing where it counts.
Energy audit is the term most people search for, but Horizon Homes does not sell energy audits. Our first step is a free energy assessment, a visual walkthrough with no diagnostic equipment and no obligation. Diagnostic audits are offered separately by registered Energy Advisors, who set their own prices. You get a thorough walkthrough and a clear plan, and if you move forward we handle the rebate paperwork and deduct the rebate from your invoice upfront.
A typical assessment takes about an hour. We walk through your entire home, look at your insulation, air sealing, heating system, and comfort issues, and take the time to answer your questions. No equipment, no disruption. We ask that you or another adult be home during the walkthrough. Learn more: The Physics of Heat Loss in Maine Homes.
Rebates vary based on the type of work and your household income. Heat pump rebates can reach up to $9,000, and insulation/air sealing rebates up to $8,000. Many homeowners offset 40–60% of total project costs through Efficiency Maine rebates. We'll identify every rebate you qualify for during your assessment. Learn more: Phasing Your Home Energy Upgrade Over Time.
No special preparation is needed. We just ask that you're home during the assessment and that we have access to your attic, basement, and mechanical systems. If you have recent energy bills handy, that's helpful but not required.
We typically schedule assessments within 1–2 weeks of your request. During peak season (fall and early winter), wait times may be slightly longer. Submit your request today and we'll confirm your appointment within one business day.
