Excellent Techs!! We had two out here on the same day, Jordan for the furnace and Terry for the plumbing, and they were both great. 5* for both! The thought that went through my mind was, "Where do they get these guys?" ... meaning that they were both great, as was the tech that checked our system last year. Whoever does the hiring does a good job. Thanks!

Except for having to purchase a new furnace, the technician was professional and courteous. Jordan explained everything on my 20 year old furnace and gave me many options to choose from. Excellent people to work with!

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.

Kevin was on time & very courteous. He discovered a leak in the furnace & suggested having it replaced. He also noticed that the filters I had were not the correct size. He replaced them. Kevin is an asset to the company

Kevin was a great technician! I learned so much from him. He was willing to take the time to explain the workings of the furnace so I understand the importance of getting it checked more often.

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.
