I have been using Assured Comfort Heating, Air & Plumbing for around 2 years now, they come every spring to do a check-up on my air conditioning unit and every fall to do a check up on the furnace. As a repeat customer, I wish things were a bit cheaper or they had some sort of rewards system. In general, I am happy with the work they do. They don't have 5 stars based on my most recent experience with them. I had an appointment at noon and the technician showed up at 8 am, which didn't work for me. He told me I had to reschedule since I wasn't available, I called the main office to get this sorted out and a technician showed up later that day at the original time. I would use Assured again as long as this doesn't happen again, it was frustrating for someone with a tight schedule.
