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.

Our approach


Why is my AC running but not cooling?

The air conditioner may have a problem with the condenser coil When properly working, the condenser coil releases heat outdoors by capturing air into its chamber. If it is not working properly it may be running but not exchanging cool air for hot air.

Is it worth it to repair an air conditioner?

It may be not worth fixing air conditioners that are over ten years old. While some systems can last 15-20 years, the harsh summer climate of Green Bay can cause a lot of strain that builds up over time.

What are common AC issues?

Evaporation coils freeze when the AC does not get adequate air for its operation. If the coil has frozen it might freeze up and stop working. It’s a common occurrence for houses in and around Green Bay WI. Here are some signs you may need to call for air conditioner repair services.

  • Surging energy bills in the summer.
  • Strange noises from the AC unit.
  • Air conditioner continuously runs.
  • Short cycling of AC unit.
  • Ice buildup in the air conditioner

Do you fill air conditioning refrigerant?

As your local Green Bay heating and air conditioning company, Comfort Control can come out and measure the refrigerant level of your air conditioning unit. Whenever a new unit is installed, refrigerant is calibrated in the beginning of the system use. Over time, the refrigerant levels may get too low, causing a series of AC system failures.

Do you work on a geothermal heat pump?

We specialize in forced air system and mini splits. If you have a broken geothermal heating cooling system, we can offer a more cost-effective HVAC system.

How soon can you start my air conditioner repair?

We are located in De Pere WI and can service the entire Green Bay area, including Brown County and the Fox Valley region.
