Have relied on CCS for many years to maintain and if needed repair our HVAC systems. As out of state owners of the home it is great to be able to call or have our tenant call, confirm with me as owner, and quickly receive service when needed. Latest example is we learned late yesterday from our tenant the furnace was not coming on. Big issue in Green Bay in February! After one call Jordan was out the next morning and checked and repaired the furnace. He also pointed out future considerations so we can plan. Highly recommend.

Tanner was very helpful. I unfortunately will need a new furnace but he helped diagnose this and helped set me up with space heaters in the meantime and even prioritized me to get an appointment for an estimate and hopefully a new furnace. I really appreciate the help and Id definitely recommend this company.

Woke up to -5 degrees outside and 50 degrees in my home, furnace wasn't working. I called Comfort Control Systems and they sent a technician out to me within 2 hours. Kevin was courteous and professional. He quickly diagnosed the problem and had my furnace up and running in no time. I've used Comfort Control Systems a couple of times now and I have had nothing but the best experiences. They are friendly, professional, and reasonably priced. They go out of their way to make sure you are taken care of. 10/10.

I had a furnace issue. Called them around 8:15 and they had a technician here by 10:45. He was done by noon with the problem solved. The service call with a part wasn't cheap but nothing is anymore. Still happy with the quick service.

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.
