The Heating Specialist installed my heating and air conditioning system a while back. They did a very good job of it. They were out on this visit to fix the furnace and in that process found an issue with the air conditioner and fixed that as well. They had to order a couple of parts but were able to get them the next day and fix those two issues. They are very reliable very friendly and they explained everything to me. I think they have the best technicians in the business! I have referred them to others and I will continue to do so. I honestly cannot say enough good about their technicians or the company as a whole!
