Commercial HVAC Maintenance

Your commercial HVAC system affects every part of your business. It keeps your employees and customers comfortable, impacts your monthly bills, and helps maintain healthy air quality. At Allied Air Conditioning & Heating, we know that regular HVAC maintenance isn't just about preventing breakdowns—it's also about helping your business run better.

Why Your Business Needs Regular HVAC Maintenance

Running a business is expensive enough without wasting money on high energy bills. A well-maintained HVAC system uses less energy while keeping everyone comfortable. Regular maintenance also helps prevent costly emergency repairs and helps your system last longer, protecting your investment.

Timing is key for HVAC maintenance. We recommend servicing your system twice a year: once before summer and once before winter. This schedule makes sure your system is ready for Chicago’s extreme temperatures. If your business runs around the clock, we’ll create a maintenance schedule that works with your hours.

Commercial AC Maintenance Services

Chicago summers put heavy demands on your cooling system. Our thorough AC maintenance service keeps your system running reliably when you need it most. Here’s how we help.

System Performance

Your AC system has many parts that need to work together perfectly. Our certified technicians start each maintenance visit by checking how your entire system is working. After arriving for commercial AC maintenance, we will: 

  • Test overall system performance
  • Test system pressure
  • Calibrate controls

These detailed checks help us spot problems early before they lead to expensive repairs or system failures.

Key Component Service

Your AC system’s life depends on keeping its main parts in good shape. Our technicians carefully inspect and maintain these crucial parts during every visit:

  • Cooling coils
  • Refrigerant levels
  • Electrical systems
  • Belts and other moving parts 

Taking good care of these essential parts prevents unexpected breakdowns and helps your system run better. Regular maintenance of these components helps your equipment last much longer.

Commercial Heating & Furnace Maintenance

Chicago winters demand reliable heating systems. Commercial heating maintenance focuses on keeping your system both safe and efficient, helping prevent winter breakdowns while keeping your energy bills in check. 

Safety Checks

A malfunctioning heating system affects everyone in your building. Our thorough safety inspections protect your employees, customers, and property. The inspections include:

  • Checking heat exchangers
  • Testing for carbon monoxide
  • Verifying safety controls
  • Inspecting the combustion system
  • Checking ventilation

These important safety checks give you peace of mind and ensure your heating system runs safely all winter.

Better Performance

A well-maintained heating system keeps everyone warm without running up your energy bills. Our technicians carefully adjust and test your system to help it run efficiently. Potential maintenance tasks include:

  • Cleaning and adjusting burners
  • Maintaining filters
  • Ensuring even heating

These adjustments help lower your operating costs while keeping your building more comfortable.

Protecting Your Investment

Your HVAC system is a major investment in your business. Our maintenance program protects this investment through careful record-keeping and preventive care. We keep detailed service records that help maintain your warranty and guide future maintenance.

Regular maintenance helps your system last longer by catching problems early. This approach helps you avoid sudden breakdowns that could disrupt your business and cost you money.

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.
