Commercial AC Services

Allied Air Conditioning & Heating Corp. has provided professional commercial air conditioning services across Northern Illinois since 1971. We service commercial cooling systems in:

  • Retail spaces
  • Office complexes
  • Industrial facilities
  • Hospitals
  • … and more.

No matter the type of building you manage, you need a commercial ac company that responds quickly and provides long-term solutions. That’s why we’re available 24/7 to address commercial AC problems as they arise. Call us now to schedule your commercial AC repair, maintenance, or installation appointment.

Commercial AC Repair

We understand that for many businesses, air conditioning is “mission-critical” equipment, and we treat every repair call with the urgency it deserves. Call us now to speak with an on-call technician.

Our team specializes in diagnosing and fixing issues that are unique to large-scale equipment, from failing economizers to complex refrigerant leaks. Rather than relying on quick, low-quality patch jobs, we always strive to address the root causes of commercial AC problems to prevent recurring downtime.

Commercial AC Maintenance

While we’re always available for commercial AC emergency services, it’s preferable to avoid those emergency calls altogether. The most effective way to protect your bottom line and ensure tenant comfort is by scheduling proactive commercial ac maintenance. During a standard commercial service visit, our NATE-certified technicians complete the following tasks:

  • Condenser & Evaporator Coil Cleaning:

We remove the dirt and debris that force your system to work harder, which immediately improves heat transfer and lowers energy draw.

  • Filter & Belt Replacement:

We replace worn belts and high-efficiency filters to ensure proper static pressure and prevent unnecessary strain on your blower motor.

  • Electrical & Control Diagnostics:

Our team tightens all electrical connections and tests sensors, thermostats, and contactors to prevent “nuisance trips” and electrical failures.

  • Refrigerant Level & Leak Checks:

We verify that your system is operating at the precise charge levels required for peak cooling performance and check for any signs of vibration-related leaks.

By partnering with Allied for your seasonal tune-ups, you aren’t just checking a box; you are optimizing your facility’s energy consumption and significantly lowering your monthly utility costs. Consistent, professional care is the single best way to protect your investment and ensure your equipment reaches its full projected lifespan.

Commercial AC Installation

When the time comes to upgrade your facility’s climate control, you need a partner that handles the entire process, from load calculations to the final crane lift. Our commercial ac installation services are focused on minimal disruption to your daily operations.

Our commercial AC installation process includes:

  1. Helping you select high-efficiency units that meet the specific demands of your building’s square footage and occupancy.
  2. Handling every aspect of the installation, including removal and disposal of your old system.
  3. Ensuring every new component is integrated into your existing ductwork or building management system.

Commercial AC FAQ

How often should I schedule commercial HVAC maintenance?

For most businesses, we recommend two professional maintenance visits per year. High-demand facilities sometimes need quarterly service.

Do you offer 24/7 commercial ac emergency repair?

Yes. We always have a technician on-call for emergency commercial ac repair.

How do I know if I need a repair or a full replacement?

Our technicians will assess your needs and space to determine the best option for you. In general, if your repair costs are exceeding 50% of the value of a new system, or if your unit is over 15 years old and requires frequent service, replacement will be the responsible option.

What Our Customers
Say About Us

We moved into a new house recently and Allied was recommended to us by my best friend.

We had them install a new humidifier and zone the system. On moving day (Friday) at 3 pm when we showed up we found the AC wouldn't shut off. I texted my tech with hopes of getting on the schedule for the following week since it was late Friday. He said someone would be there in 30 min. They stayed for 2 hours and fixed a faulty wire and it was all covered under warranty. Can't argue with customer service like that. Highly recommend if you want dependable folks that are very responsive.

We were extremely pleased by the service that Allied provided us.

Our A/C went out over the 4th of July we knew we needed a new system installed asap (we knew it was on its last leg). We contacted them and two other companies for comparison quotes. Allied was out here first thing July 5th to assess and provide a quote. In the end we decided to go with them. They were professional, thorough and very detailed in options and quotes.

Moved into the neighborhood and Allied HVAC had been recommended from my brother to replace both our furnace and ac unit.

Very professional from the start with a quote from Chris B. in sales which lead to an install date of my choice. On the day of the installation Jeff and Jackson arrived right on time as requested. The installation was prompt and done in a timely matter, and it they explained exactly what needed to be done from start to finish.
