777 HVAC

777 HVAC is a heating and cooling business with a 5-star Google rating from 41 ratings. Its website lists HVAC installation, maintenance and tune-ups, repairs, ductwork and thermostat work, and names a service area that runs from Manchester, Augusta and Waterville to Lewiston, Auburn, Brunswick and Portland. A recent customer said the company installed a heat pump in a new studio space and that it heats well. When heat pumps went out over a weekend, a customer said Travis came out immediately, found a broken coil and left every unit running. A customer whose heat pump problem a different company had not fixed said 777 HVAC sent someone a few days after the first call who laid out a few options. A customer who bought a couple of historic buildings said the company got there within the hour and worked through the weekend to fix multiple emergencies. During a heat wave, a customer said Travis got their central air running and called the pricing very fair. A customer said Travis and his crew came within an hour when a garage was at risk of falling down, then spent a day and a half fixing it; in an update, that customer said Travis came the next day when the hot water heater went out. In a 2025 review, a customer said Travis found a heat pump layout that worked with limited wall space, and the company also installed surge protectors. In a 2025 review, a customer with an energy efficient house said Travis did not try to sell oversized units and had the job done in a couple days.
