AC Repair

Air conditioning systems are strong and durable, but they are not indestructible. As components wear out and need replacing, our team of certified air conditioning experts will apply the most appropriate solution for your needs.

Common causes of air conditioning failure include:

  • Frozen compressor coils
  • Leaking refrigerant lines
  • Defective motors
  • Faulty thermostats
  • Clogged drains
  • Blown breakers or fuses
  • Worn contactors

AC Installation & Replacement

We specialize in the installation of Carrier brand ductless and conventional air conditioning systems. These highly reliable systems are well-suited to the regional climate and will deliver a steady stream of cool air that will keep you comfortable all summer long. As with furnaces and boilers, our certified HVAC technicians will help you identify the best system for your desired comfort.

Furnace Repair

Your furnace will provide reliable, energy-efficient comfort for 15 to 20 years with regular maintenance and prompt repairs. When clients in the Chicago region reach out to our team, it’s usually because the following furnace problems are occurring:

  • The furnace is blowing cold air.
  • The pilot light keeps blowing out.
  • The thermostat is malfunctioning.
  • The furnace is frequently cycling.
  • The furnace is operating loudly.
  • The filters are clogged.

Our teams work quickly to identify the cause of the problem and apply the appropriate repair. Whether it’s a damaged heat exchanger, a clogged pilot light, or a loose wire, we thoroughly inspect the system to determine the best way to resolve the issue.

Furnace Installation & Replacement

We highly recommend Carrier furnaces and Weil-McLain boilers to our clients in Chicago. We will help you identify the best solution and most appropriately sized system for your needs. Our installation teams will remove and dispose of your current system and thoroughly test your new heating system when the installation is complete.

Furnace & AC Tune-Ups

Tuning your furnace and air conditioner once a year is an effective method of prolonging their operational life span. It will also help preserve energy-efficient operations and minimize your long-term repair costs. At Comfort Zone Service, our certified HVAC technicians are happy to tune up your furnace, air conditioner, and other systems.

Very quick response time! I noticed the failure of my hot water heater at 7 pm one evening and had a new hot water heater installed and ready to go by 11 am the next morning. Great communication, clear recommendations, and took the time to explain details about the equipment that was ultimately installed.

Ryan H.

We have worked with Comfort Zone for about 4 years and are completely satisfied with the quality of service they provide. They recommended and installed a new AC unit, and provide us an annual furnace and AC cleaning and inspection service. We highly recommend this company for residential heating and cooling needs.
