"Incredibly professional, always happy to answer questions. Unlike other places that install and you never hear from again, Cam, David, and crew make sure your heat pump stays in tip top shape with yearly cleanings. They even offered to clean a unit that another contractor put in a year prior who refused to come clean it. I got quotes from over 8 different companies for my second heat pump, and Heat Pumps of Maine were a clear step above the rest."

"Techs were very nice. Took time to put mats down on my carpets to keep them clean. Explained how to operate the heat pump and gave suggestions on how to make it function most efficiently. Everything was cleaned up before they left, they even vacuumed! So glad I went with LaPlante for my heat pump! Bev"

"Matthew and his crew were extremely professional and efficient. The work was completed on the day scheduled and they cleaned up after themselves. Heat pump works great and they were able to direct me to an Effeciency Maine site where I received a substantial discount on the installation, equipment and cleaning plan!! Great company to do business with and will recommend them to family and friends. I will definitely not hesitate to use this company again if the need should arise!!"

"Brady from Maine Way Heating & Cooling. The gentleman came when expected, very pleasant and knowledgeable. His quoted price was very reasonable and less expensive then the company we used last year. He did find that we needed another part to complete the job he was not pushy about selling it and stated we could schedule an appointment. After talking with him we asked him to go ahead and fix it. This gentleman is very professional and very upfront with his price ...We will for sure call him again next year for service and with any emergencies we may have. Thank You Brady!!"
