Customer Reviews
5 Stars Across the Board
Don't take our word for it — here's what homeowners across southern Maine say.
"Our furnace quit on us during a January cold snap. Southern Maine Mechanical had someone here within two hours. Fast, professional, fair priced. They even followed up the next day to make sure everything was still running. Only HVAC company we'll ever call."
Sarah M.
Scarborough, ME
"Had a new mini-split installed last spring. The crew was on time, kept everything clean, and walked us through the whole system before they left. This summer was the first time in years our upstairs was actually comfortable. Couldn't be happier."
Tom & Lisa K.
Falmouth, ME
"I've used a couple of HVAC companies and always felt oversold. These guys diagnosed the problem, told me exactly what it would cost, and fixed it for exactly that price. Straight shooters. Highly recommend."
Derek P.

Amanda R.
