Horizon Homes sells home energy upgrades, and its BBB profile describes weatherization and heat pump installation, including insulation, air sealing and the installation of heat pumps, windows and doors. On its website, the company describes itself as family-owned and says that since 2006 it has helped over 2,500 Maine families cut their energy bills. The service area it lists runs from Westbrook and Portland out to Brunswick, Freeport, Standish and Cape Elizabeth. Google shows 4.8 stars from 71 ratings. A Google customer says the workers arrived on time, cleaned up completely and finished in half the time shown in their estimate, then billed only for actual time rather than the estimated cost. A Google customer says they sent the right guys to represent the company. A Google customer says the tech was over 20 minutes late, spent about 15 minutes on a quick visual inspection, and sent what they called a massively overinflated quote a few days later. That customer says Horizon will only do energy tests once a customer has engaged with them for the full cost of the project, and advises working with an energy auditor who will do tests and give a baseline first.
Tech was over 20 minutes late and then spent about 15 minutes taking a quick visual inspection of our property. Sent a massively overinflated quote a few days later. It would take us over 35 years worth of 100% savings on our energy bills to recoup their proposed costs of improvement. Do yourself a huge favor and work with an actual energy auditor who will do some tests and give you a baseline for where and how much you can improve your home's energy usage. Horizon will only do that once you've engaged with them for the full cost of the project, others will do it as a baseline and go from there.
Very happy with my experiance with Horizon, from start to finish.
Great crew great experience. They sent the right guys to represent the company
These folks exceeded my expectations. They arrived on time, did a very thorough and professional job, cleaned up completely and finished in half the time shown in their estimate. The most surprising part to is that they only billed for actual time, not the estimated cost. That is more than rare in today's world.
