A 2024 HomeAdvisor customer said the company's technicians installed a new furnace and explained how the cost could be minimized without compromising the quality of the work. A 2025 Google customer said the company replaced their water heater with a new model and called the service responsive and fairly priced. A 2024 HomeAdvisor customer said they would recommend Ian and his crew in a heartbeat. Its Maine hvac license, number PNT6524, is active on the state registry, with IAN S.

Replaced water heater with new model, very responsive service and fairly priced.
I canâ t say enough about Ian and his crew.They were in all honesty the best Iâ ve had working on my house.Ian went above and beyond anyone Iâ ve encountered working on my house.I would recommend them in a heart beat.
I couldn't be happier with my experience with Great Bay! We had a heat pump that wasn't blowing cold air. I called Ian and not only was he polite answered all my questions but he came out the next day and my unit was fixed and cleaned the following morning! Ian and his team were such a pleasure to work with. I can't reiterate that enough. If you need your unit serviced or if you need a new system. Be sure to give them a call. I promise you will be as pleased as I am.
Amazing people, their punctulity, professionalism, and their quality work is so amazing. This company technicians installed a new furnace for me in March 2024.These technicians are so knowledgeabl and humble to explain to me how my cost could be minimized without compromising the quality work. They deserve appreciation.
