Active Heating, Inc. really did a very good job, and I was satisfied with their service. I was having issues with my heating and air conditioning system, and other companies were having difficulty in identifying the problem. I found Active Heating, Inc. through an internet search, and had a short service call because they were quickly able to find the problem. Their workers were very professional and knew what they were doing. Their front office was also very courteous when setting up my appointment. This was my first time using their services, and I would do so again.
