I have been using the service of Assured Comfort Heating, Air & Plumbing for about two or three years. They always return my calls and they are always on time to repair the equipment I have called them about. They're just all around a good company to work with. Most recently they changed the filter in a furnace for me. This is an annual job and overall it's been a good experience with them. They are professional and competent. They are communicative and explain everything.
