Heat Relief Heating & Cooling has worked on my HVAC unit several times. Everything is working fine. They always take the time to let me see what they are repairing and to let me know any problems they see that I may acquire in the future. The last time they came out, the young man showed me how worn a motor had gotten before he replaced it. Since an HVAC system is such a large investment, I appreciate the time they take to keep my older model up and running. They have spoken with me about a replacement, but they are never pushy. I highly recommend them because I respect the job they do and the good workmanship.
