"I'd been wanting to get of our old electric baseboard heaters for a long time, and replace it with something more efficient, and Mark helped my understand the differences between a ductless mini-split system and a ducted heatpump system. Even in our small house, the ducted system was the way to go. Mark and his installers were professional and efficient, and answered all my questions. When the thermostat was acting a little odd, he sent a technician over to calibrate it, free of charge. There was a small issue where I initially got the wrong specs for the electrical, and as a result I had the electrician install unnecessary circuits, but Marc reimbursed me for the cost."

"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"Cory and Joe were fantastic. The installations went without a hitch. The overall cost was lower than three other quotes I had received for the job. At the beginning of the A/C install I noticed the water heater was leaking, and they were able to replace it the next day. I will definitely use them again."

"Review for Bassett Home Heating, Inc.: In early February of 2022, John Bassett of Bassett Home Heating, Inc., the representative of the family-owned and operated heating and cooling company, responded when I asked for an estimate to remove an old gas furnace and install a new gas furnace and an air-conditioner in its place. John showed up on time and discussed the project in detail. In addition to the fact that Bassett featured American Standard products, I was impressed by the 3-year maintenance agreement (A/C and furnace) I could purchase wherein a company representative would stop by each winter and each summer to maintain our new furnace and air-conditioner. I requested that the furnace and A/C be installed before June and they were installed on May 23 by John’s son, David Bassett. David showed up with a 3-man crew and the installation was completed in less than a day. I was impressed by the competence and professionalism of the installation. Bassett was able to use my existing programmable thermostat (which was fairly new), and David took the time to explain how to operate it for the furnace (heat) and the air-conditioner (cool). The air-conditioner and the furnace have both operated exceptionally well throughout the summer, fall, and upcoming winter. I would rate the total experience as 4 out of 5 stars. Although the products and installation were top notch, communication with the office was inconsistent. I paid the revised balance of my bill shortly after installation (which was less because a new thermostat was not needed). I was told that there were computer problems when I called, emailed or left voicemails requesting a copy of the revised invoice as proof of payment that I could supply to Puget Sound Energy for an energy rebate. Five weeks after installation, I received a revised second invoice and updated paperwork in the mail."
