Commercial AC Installation

A commercial cooling system is one of the most significant investments any business will make. The quality of the installation can affect the system’s efficiency, lifespan, and reliability for the next two decades. That’s why you need a commercial AC installation company that understands the physics of high-tonnage cooling.

At Allied Air Conditioning & Heating Corp., we’ve provided expert commercial AC installation services throughout the North Shore and Northwest suburbs since 1969. Reasons businesses enjoy working with us include technical expertise, transparent pricing, and family-owned values.

Call us today or reach out online to schedule your commercial AC installation.

Technical Expertise for High-Capacity Projects

Commercial cooling requires a level of expertise many HVAC contractors don’t have. A 25-ton rooftop unit (RTU) has vastly different airflow, electrical, and structural requirements than a residential unit. At Allied, our NATE-certified team has the experience and the “mechanical horsepower” to manage every aspect of your commercial AC install, including:

  • Comprehensive Load Calculations: We perform rigorous Manual N and Manual Q calculations to ensure your system is perfectly sized for your building’s occupancy, window surface area, and internal heat loads (like server racks or industrial machinery).
  • RTU & Split System Integration: From crane-assisted rooftop placements to integrating complex multi-zone split systems, we handle the logistics of the installation from start to finish.
  • Building Automation (BAS) Connectivity: We ensure your new equipment communicates flawlessly with your existing building controls for maximum efficiency and remote monitoring.
  • Ductwork & Air Balancing: We verify that your ductwork can handle the static pressure required for optimal performance.

By focusing on these technical details during the commercial AC installation process, we ensure that your system operates at peak performance from day one, reducing the likelihood of premature wear and expensive emergency repairs.

Why Choose Allied for Commercial AC Installation

At Allied, our recommendations are based on mechanical logic and your building’s needs. Other reasons Northwest Chicagoland area businesses choose to work with us include:

  • No Sales Quotas: Our technicians are paid for their mechanical expertise, not their sales volume. If your unit can be logically repaired, that is exactly what we will recommend.
  • Transparent ROI: We don’t use high-pressure pitches. Instead, we show you the math on energy savings and maintenance costs so you can see exactly when a new installation will pay for itself.
  • A 30-Year Perspective: We aren’t looking for a one-time transaction. We want to be the team you trust to maintain your facility for the next three decades.
  • PE-Free Service: Because we aren’t owned by an investment group, we have the freedom to give you honest advice all the time.

Protecting Your Investment Post-Install

Even the most perfectly executed commercial AC install requires ongoing care to maintain its efficiency. High-tonnage equipment operates under significant stress, especially during Illinois heatwaves. To ensure you get the maximum ROI out of your new system, we offer tailored commercial ac maintenance plans that catch minor issues before they lead to business interruption.

If you are currently managing a system that is struggling to keep up, or if you are planning a major facility upgrade, let Allied provide the straightforward assessment you need. We’ll help you choose the right technology for your specific square footage and budget.

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.
