Commercial Air Conditioning Services in Cook & Lake County, IL

Heating, cooling, and indoor air quality are just as important to your business operations as having well-trained employees and a solid roof over your head to keep the elements out. Assurance Heating & Air Conditioning, Inc. technicians have decades of experience working in the commercial HVAC industry, installing, maintaining, and repairing heating and cooling systems for companies of all sizes.

Designing from the Ground Up

There is never a one-size-fits-all HVAC solution for any building. Every system we install goes through a comprehensive design process that takes into account dozens of variables including floor area, window area, level of insulation, and building orientation. By taking the time to carefully complete load calculations, we can minimize the installed cost of your system, maximize its efficiency, increase its lifespan, and save you money in the long run. We’ll also work closely with your team to finalize all of the details including everything from vent placement to system access.

Our 24/7 Repair Team

Emergencies wait for nobody, and when disaster strikes, we’ll be there to get your HVAC equipment back up and fully operational. Whether it’s a cold snap or heat wave, employee and customer comfort is key to keeping your business running smoothly. Our experienced air conditioning repair technicians will work to identify any system malfunction and either repair it the same day or, if needed, replace it as quickly as possible.

The Assurance Maintenance Plan

As your Buffalo Grove and Northwest Chicago HVAC contractor, our goal is to ensure you have a heating and cooling system that works efficiently and saves you money. To that end, we offer a preventive maintenance plan that offers a number of benefits including:

  • Replacing air filters
  • Measuring refrigerant pressure
  • Inspecting fans, motors, and other components
  • Inspecting wiring for wear
  • Priority service

These flexible plans are the single best way to maximize system performance and comfort while adding years to your HVAC system’s life. In the event that you require additional air conditioning service, you’ll receive discounts on parts and labor and avoid any overtime fees.

Because commercial systems are significantly larger and more complex than residential units, purchasing a maintenance plan allows us to provide better service over time in the same way that a mechanic can get to know a family car over the years. With a working knowledge of your system, our technicians will be able to more quickly and accurately troubleshoot issues to minimize any disruption to your business. For more information on commercial maintenance, please give us a call.
