We received notification in Dec., 2023, that maintenance was due on our furnace, heat pump and all other parts. Due to the holidays and sickness, I put this off. On Jan., 2024,when the ice and snow storm came, the heat pump was really working hard and making a loud sound. When I called to inquire about it, the gal on the phone was very helpful in explaining about the noise. At that time, I ordered a maintenance visit which was scheduled in a couple of days. Technician Justin came out and did the job. All was working well. He was kind, friendly, informative and encouraging. We have used Best Heating and Cooling for a few years now, and highly recommend them. Barb M.
