    We recently had our first service visit from Hall Air. The technician Scott was thorough with a comprehensive inspection, gave us good advice and recommendations and answered all of our questions. He is very knowledgeable and straight forward and gave us an excellent assessment of our current systems and future options. Thank you.

    Jonathan was our sales person who clearly proposed what would be the best system for our home taking advantage of available promotions and tax rebates. The installation was completely seamless and we hardly knew the team was here. A 2 unit install was completed within the day. Afterward, they explained everything about the system and how to maximize the controls for comfort and efficiency. Great experience!

    I rarely write reviews but will make an exception when service is outstanding. That is the case with Hall Air. Hall provided exceptional service when I was without heat for a few days. I called on a Sunday afternoon and got their answering service. The person I spoke with was very helpful. Sunday evening, Lani with Hall reached out via text to say she could send a technician the next day (Monday). It started snowing Monday morning, but that didn't stop Hall from arriving. I got a text early afternoon letting me know the technician, Scott, was on his way. While I waited, I called the office to discuss payment. I spoke with Lani who did a great job explaining the benefits of their maintenance plan. Scott arrived shortly thereafter when it was cold, windy and snowing heavily. He was polite, professional, and positive. He got the heat back on immediately! We discussed the maintenance plan further, and I opted in. I highly recommend Hall Air for their responsiveness, expertise and commitment to the customer. Julia
