I have had no problems with Comfort First Heating & Cooling. I had them come out about a month ago to check our heating and air conditioning units. It was part of our service contract with them. They replaced some parts in the air conditioner, and cleaned our heater. Everything was great. They called us ahead of time to let us know they were on their way, and the worker was on time and professional. I may not continue with my service contract, but I would still use them in the future.
