Commercial HVAC Repair

A reliable HVAC system is essential for any business. It doesn’t matter if you operate an office, restaurant, retail store, or industrial facility. Maintaining the right indoor temperature keeps employees comfortable, customers happy, and equipment running smoothly.

When your heating or cooling system malfunctions, it can disrupt your business and lead to costly downtime. That’s why prompt, professional commercial HVAC services are critical.

At Allied, we provide expert commercial HVAC services for businesses throughout Chicago’s north and northwest suburbs. Our team has years of experience diagnosing and fixing all types of commercial heating and cooling systems. Work with us to ensure your business stays comfortable year-round.

Our Commercial HVAC Repair Services

A malfunctioning HVAC system can disrupt your business, leading to discomfort, increased energy costs, and potential equipment damage. Whether you’re dealing with heating or cooling issues, our expert technicians provide fast, reliable commercial HVAC repair to restore comfort and efficiency.

We specialize in diagnosing and repairing all types of commercial HVAC systems, ensuring minimal downtime and long-term performance.

Commercial Furnace Repair

Reliable heating is essential for businesses, especially during Chicago’s harsh winters. If your furnace isn’t producing enough heat, cycles on and off too frequently, or makes unusual noises, it may be time for repairs. Common furnace issues we fix include:

  • Ignition failures that prevent the system from starting
  • Weak airflow due to clogged filters or blower motor problems
  • Thermostat malfunctions causing temperature inconsistencies
  • Strange noises indicating loose or failing components

Timely furnace repairs not only restore warmth but also improve energy efficiency and prevent more costly breakdowns. If your heating system isn’t keeping up, our skilled technicians are ready to help.

Commercial AC Repair

A failing air conditioning system can make your business unbearably hot, affecting both employee productivity and customer experience. If your AC is blowing warm air, struggling with airflow, or running inefficiently, professional AC repairs can restore cooling performance. We commonly fix:

  • Refrigerant leaks that cause inefficient cooling
  • Compressor failures leading to system shutdowns
  • Frozen evaporator coils restrict airflow
  • Electrical malfunctions preventing proper operation

By addressing AC issues early, you can reduce energy costs, extend equipment life, and maintain a consistently cool environment. Our team works quickly to diagnose and repair your system, minimizing disruption to your business.

Signs Your Commercial HVAC System Needs Repair

Your HVAC system is one of the hardest-working components of your building. Over time, wear and tear can lead to problems that affect performance and efficiency. Recognizing the warning signs early can help prevent costly breakdowns.

Common indicators that you may need commercial HVAC repair include:

  • Inconsistent Temperatures: If some areas of your building are too hot while others are too cold, your system may have airflow or thermostat issues.
  • Unusual Noises: Banging, rattling, or squealing sounds can signal mechanical problems that need immediate attention.
  • Increased Energy Bills: A sudden spike in utility costs often means your HVAC system is working harder than it should.
  • Poor Airflow: Weak airflow from vents could indicate a clogged filter, blocked ductwork, or a failing blower motor.
  • Frequent Cycling: If your system turns on and off frequently, it may be struggling to maintain temperature due to an issue with the thermostat or compressor.

Addressing these issues quickly can prevent further damage and keep your system running efficiently. Regular maintenance also plays a crucial role in preventing issues that require commercial air conditioner repair before they start.

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.
