Allied Air Conditioning & Heating

Commercial HVAC Services

Your business relies on its heating and cooling system to keep running smoothly. At Allied Air Conditioning & Heating, we've been helping Chicago businesses keep their buildings comfortable and energy-efficient for over 55 years. Whether you run a retail store or manage an office building, we have the commercial HVAC services you need.

Complete Commercial HVAC Solutions

Different businesses need different types of heating and cooling services. Our team offers a full range of services to keep your building comfortable all year long.

Commercial AC Services

Every business has its own cooling needs. A restaurant’s commercial AC unit works differently from an office building’s system. We offer services that cover all types of commercial cooling needs:

These services help make sure your cooling system works reliably during Chicago’s hot summers. Our team knows the latest cooling technology, so we can offer you the best solutions for your business.

Commercial Heating Services

Chicago winters can be tough on heating systems. Our heating services keep your business warm even during the coldest weather:

Taking care of these heating needs helps prevent unexpected breakdowns while reducing your energy bills. We spot and fix small problems before they become big ones that could shut your business down.

Understanding What Your Business Needs

Every business faces different challenges with heating and cooling. A small shop needs different things than a big warehouse or a modern office building. We know how to create solutions that work for your specific situation.

We look at everything that affects your heating and cooling needs:

  • How big your building is
  • When your business operates
  • How many people use the space
  • What kind of equipment you use
  • How much you want to save on energy
  • What fits your budget

Understanding these details helps us design systems that work better and cost less to run. We balance keeping people comfortable now with saving money in the long run.

Expert Installation of Commercial Systems

Installing a commercial HVAC system takes careful planning and skilled work. We follow a step-by-step process that we’ve perfected over decades:

  1. Checking your building thoroughly
  2. Designing your system
  3. Professional installation
  4. Testing everything works right
  5. Training your staff
  6. Ongoing help when you need it

This careful approach ensures your new system works exactly as it should while keeping disruption to your business minimal. We coordinate everything to keep your project on schedule and within budget.

Commercial HVAC Maintenance

Regular maintenance keeps your HVAC system running reliably. A well-maintained system works better, costs less to run, and lasts longer. Our maintenance programs protect your investment.

During each maintenance visit, we:

  • Inspect your entire system
  • Replace filters
  • Clean all components
  • Test how well everything works
  • Check all safety features
  • Give you detailed reports

This thorough maintenance helps us catch problems early, before they cost you a lot of money to fix. Our detailed records help you track how your system is doing and plan for the future.

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.
