Commercial Air Conditioning Repair and Installation Services in Southwest Chicago, IL

Commercial air conditioners are the workhorses of the HVAC world. They must achieve a level of performance that residential units couldn’t hope to achieve. Their superpowers generally come from their large rooftop terminal units, which can control temperatures one room at a time. Since water-cooled chillers can sustain low temperatures for longer, they’re usually the technology of choice. Comfort Zone specializes in commercial cooling services so that we can bring you the finest technologies in the industry.

Got an Emergency?

We Can Help!

Commercial AC Replacement

The humble residential air conditioner doesn’t pack enough punch for large businesses, so your replacement will probably require technology that you’re unfamiliar with. We’ll help you choose the perfect replacement for your budget and building design. We install:

  • Multi-split units: This technology has a few things in common with single-split residential units, but it connects to several indoor ACs. These units are popular among larger businesses like malls and sprawling office complexes.
  • Variable refrigerant flow systems: These powerful units can heat and cool the biggest commercial spaces. They allow your tenants to set their thermostats without overburdening your technology.
  • High-capacity units: Your commercial system should have enough cooling capacity for your square footage. We’ll help you do the calculations required to choose the perfect option.

The quality of your installation is crucial to the lifetime performance of your unit. Mistakes can hamper your AC’s efficiency permanently. Comfort Zone has been installing commercial HVAC equipment since 1988, so our exceptional skill is tough to beat. Call us to schedule an installation at (708) 403-3434.

Commercial AC Repair

Commercial units are hard workers that frequently need repair. Their specialized components aren’t always easy to source, so choosing a repair team that regularly works with commercial HVAC units is best. Our certified technicians can offer lasting, on-point repairs for specialized brands like Trane, McQuay, and Daikin. We repair both multi-split and variable refrigerant flow systems. You need a repair if:

  • Your AC noise is disrupting your staff.
  • Your team is uncomfortable with your humidity levels or inconsistent temperatures.
  • Your power bills have risen without explanation.
  • You see condensation on your unit.
  • You detect the scent of R-22, mold, or mildew.

An ailing commercial air conditioner can quickly generate weak profits. If your workers and clients are laboring under intense heat or humidity, lost productivity and sales will follow. That’s why Comfort Zone offers instant radio dispatch. Our rapid response and fast repair times assure you of quick results. Our technicians are trained to work with this unique technology, and they work according to your schedule rather than their own.

Commercial AC Maintenance

According to Gartner, downtime costs businesses an average of $5,600 a minute, so performing regular preventative maintenance is crucial. Our commercial tune-ups will keep your unit clean, cool, and efficient. Regular maintenance minimizes the odds of unexpected breakage, but it has as much effect on your efficacy. Our inspectors will ensure that your unit can cool your business without producing humidity and patchy cooling effects. A well-maintained AC provides clean, dry air, so it even affects your clients’ health. Schedule a service with our NATE-certified crew at 708-403-3434.

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.
