I have been using Superior Comfort Heating and Cooling for a long time and they do high-quality work. They recently installed a humidifier in my home and they did such a good job that now my son is hiring them for the same work. My only complaint is that sometimes they are hard to get a hold of. One time I didn't have the time to see if they would call me back so I had to hire another company. I ended up regretting that since they weren't as good as Superior Comfort Heating and Cooling.
