Our blower stopped working, Don responded to my call and came over next morning. Instead of replacing the blower, he just changed the failed part. Don really stands for his reputation and I highly recommend him.

Once again, thank you Don!!! You've always been honest and taken care of my heating and air issues. I sincerely appreciate you're around to help take care of my 20 plus years Heating and AC unit. I hope you're around when I need a replace the unit. Thank you!!

Prior to calling a HVAC company, I did a bit of research here on Yelp and read the reviews. Cobalt was local and had great reviews. Our furnace is probably 20+ years old and it has never worked properly. Our previous contractors installed new ducts in the attic and still performance was very weak. Our AC went out last summer and decided to get rid of the ac unit all together. During this winter, it just didn't seem that we were getting any warm airflow and the back rooms remained cold. Don and Chris arrived on time and troubleshooted our heater. Since we didn't have a ac unit, the removed the coil, cleaned the blower and replaced some parts. They did some before and after tests and our system has never worked this efficient in the 17+ years we have owned our house. It is 1000%+ better! I am so happy we found Cobalt!

Installed new ac instead of fixing. Worst of all, they managed to break our heater. Suggest you stay away from this company.
