A 94-year-old with no air conditioning in a heat wave got a visit the next day: a recent customer said they went out and worked in the heat to fix her outdoor unit. Integrity Comfort Heating And Cooling describes itself on its website as a small family owned company in South Berwick, ME that installs, services and maintains heating and cooling units, with a focus on heat pump installation. It holds a 5-star Google rating from 612 ratings. A recent customer had a new mini split system installed and said Andrew Landry explained the process, the remote control buttons and how to fill out the product registration. A recent customer said the team installed a Fujitsu heat pump, showed up on time and cleaned up after, and that Jeffrey answered questions before and after the install. A recent customer said Jeff came the very day they called about an old oil furnace their oil company could not fix, and that the once very noisy furnace is now so quiet they barely know it is on. A recent customer said Cole found a refrigerant leak, charged the system and tightened the connections at the outdoor unit, and plans to pressure test the three circuits next spring. A recent customer said Andrew noticed a cracked heat shield during a cleaning, showed them a picture and said he would order the part, which is covered under the warranty. A 2025 customer said Andrew replaced a fuse and refilled the refrigerant in a heat pump after another company had said it all had to be replaced. A 2023 customer said the company installed a heat pump with an oil backup system, and when the supply house supplied the wrong furnace, the company corrected it at its own loss; that customer also mentioned an occasional miscommunication. A 2025 customer said the company would not quote a moderately priced replacement boiler and was told it installs only high-end units. A 2024 customer said the install team was on time and left the premises clean, but that the office could have been clearer about what it expected of the electrician providing power to the units, who ran out of time to finish in his window.
Exceptional care and workmanship. Great customer service. Highly recommended.
Excellent and right on time to do the heat pump cleaning and checkup...Also appreciated not having to wait a week or two for service. Great all around
