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 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.

Schedule Before the Heat

Your Cooling System Should Make Cool Air

The last time you want to find out there could be a problem with your air conditioner is during a heat wave. Get an air conditioner tune up in the spring rather than during the cooling season. You will know when it only blows hot air.

Your AC unit requires a tune up for proper operation and air flow. We can help protect your air conditioner, increase efficiency and avoid costly repair to your HVAC system.

$100 Off

Air Conditioner Tune Up Special

Comfort Control is offering $100 off the current price of our air conditioner tune ups. The regular price is $225 but for a limited time, we are offering a complete ac tune with a 21-point inspection, cleaning of the outdoor unit and with a NO BREAKDOWN GUARANTEE for one year.

This is a fantastic deal on regular maintenance for your air conditioning system. Book before peak cooling season and save. Contact our main office or schedule online.

Air Conditioner tech outside

Regular maintenance is important in order for air conditioners to operate correctly. Efficiency is key to help save on utility bills, and it is always better to maintain rather than replace.
