Kevin and Jeremiah did an excellent job of informing me of what my furnace needed and how much it would cost. They took the time to explain the repairs and why it was a good thing to get those items completed. Thank you.

We had our furnace stop working in december during the middle of the night. I called them when they opened and they had someone at my house in a few hours. They even explained to me exactly what was wrong. How i can fix it if it happens again on my own. They were professional informative and a joy to worke with. I will 100% be using them for any future hvac needs.

Installed furnace and ac system last year and it has worked great. Install crews were professional and courteous. I went to replace my filter after one year and a part was bad. I called them and they hooked me up with filter upgrade for free. I recommend.

After our basement flooded with a foot of water during the recent storm, our technician made sure the furnace wasn't damaged and that it was ready and safe for winter. He also got the water heater going again after water got into a gas filter and it wouldn't light.

Save Money with Annual Inspections

Minor issues with a heating system can lead to a major furnace repair or furnace replacement down the road.

Also, regular tune ups will help improve efficiency and save money on your gas utility bills. During peak natural gas prices of the winter months, energy efficiency of your heating system is critical.

Stay Safe with a Furnace Safety Check

Older natural gas furnaces have the potential to leak carbon monoxide into the air. Your furnace air filter cannot capture the leaking gas, which can be dangerous. Schedule a Comfort Control HVAC technician to inspect your furnace.
