Stop Sweating Over AC That Can’t Handle the Chicago Heat

Your Air Conditioner Is Telling You It’s Time for a Replacement

lineup of comfort zone service trucksChicago summers are demanding on your AC system. Years of heavy usage when temperatures climb results in serious wear and tear, frequent AC repairs, and lost efficiency. Your aging AC unit may be costing you more in repairs, maintenance, and high electric bills than it’s worth.

Here are the most common signs it’s time for your air conditioner to be replaced and upgraded:

  • Electric bills are rising. Older AC units have to work harder to keep you cool. You’ll notice it when your utility bills arrive – an older, inefficient AC system is a major energy hog.
  • Your air conditioner doesn’t cool the house. If your AC runs around the clock but the house never gets cool, your AC unit may no longer have the oomph to do the job.
  • Your home is humid. Your AC doesn’t just cool the home. It controls humidity, too. If the air in your home feels more humid than normal (even if it’s cool), your AC is struggling.
  • Your air conditioner needs frequent repairs. Minor AC repairs are a normal part of routine upkeep. But when repairs become more frequent or costly, AC replacement may be more economical.

Replacing an aging air conditioner with an ENERGY STAR®-certified model can save up to 20% on annual cooling costs and vastly improve comfort and air quality in your home.

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.
