HVAC Service in Tinley Park

Technical insight and the proper application of engineering are crucial to effective HVAC installations and service. Imprecise load calculations make your system ineffective and inefficient, which is why our technicians never guess. We’ll leverage the science and modern technology to help you choose the best system for your needs and housing specs and keep it running in top condition for years to come. We’re always available, so you can get the service you need even on holidays.

Air Conditioning Installation and Repair in Tinley Park

A well-cared-for air conditioner can operate for over a decade with only minor repairs and annual tuning, but eventually you’ll need a new unit. Our team can help you determine the best new unit for your needs and install it so it performs perfectly. We can also tackle the necessary maintenance tasks of duct cleaning, filter exchanging, and general troubleshooting. Trust our inspection pros to identify whatever may be ailing your unit.

Furnace Installation and Repair in Tinley Park

Tinley Park can have brutal winters. When the temperature dives below freezing, you need to know you can rely on your furnace. It’s also important to consider the value of a humidifier to keep your home comfortable as well as warm when the harsh, dry air of your furnace starts blowing. Let Comfort Zone help you meet Illinois’ minimum efficiency standards and clearance so that you can finally achieve affordable heating. Good installation means safe, effective, high-performance results. Our team always keeps in mind our one-trip, fixed-right guarantee.  

If you’re unsure of whether your furnace needs repair, look for these symptoms:

  • Your furnace has an unusual scent.
  • Your pilot light is discolored.
  • Your furnace isn’t generating enough heat.
  • You’re hearing odd noises.

Furnace Inspections and Tune-Ups in Tinley Park

Yearly furnace inspections and tune-ups can mean the difference between a furnace that lasts its full life span without incident and one which requires near-annual repairs, runs inefficiently, and dies early. More importantly, combustion-based furnaces behind on inspection can become dangerous, with risks such as carbon monoxide poisoning.

Call us at 708-403-3434 before the cold season starts, to make sure sitting idle hasn’t caused problems. Let our A+ BBB rated professionals show you why we’re rated so highly and display our dedication to service excellence.    

Indoor Air Quality Services in Tinley Park

Poor indoor air quality can have a catastrophic effect on your health, with problems ranging from allergies to an increased risk of cancer and other serious illnesses. Working with HVAC means an intimate understanding of how air moves and what moves with it. Our team will test for volatile organic compounds, carbon monoxide, particulate matter, and more, according to strict EPA standards. Once we understand your problems, we’ll help you choose solutions such as whole-home air purifiers, whole-home air filtration systems, UV light treatment systems, and humidifiers/dehumidifiers.

Trust the pros at Comfort Zone to service your heating, cooling, and IAQ systems. Call us at 708-403-3434 to arrange service.

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.
