I have been a customer of American Comfort Heating & Cooling for several years. They recently did some work for me on two of my rental properties. On one property they replaced an HVAC unit, and they did some troubleshooting at another property. The units are working great at both locations. I can always trust them to do a good job. They arrive on time and give me an honest estimate of what will be involved in doing a repair. I recommend them because they are trustworthy and equally skilled at repair work and new installations. I have no reason to use anyone else.
