Commercial Air Conditioning Repair & Maintenance

When those high summer temperatures hit Missouri, one of the worst things that can happen to your commercial building is a broken AC. If this happens, Design Aire has got you covered!

Insufficient airflow
Loud noises or humming
Irregular cycling

Bad odors
And everything else in between!

In addition to diagnosing and repairing air conditioners, our knowledgeable team can also help prevent smaller issues from becoming larger problems with regular commercial HVAC maintenance services.

Commercial Furnace Repair & Maintenance

Missouri winters are no joke, and if issues arise with your business’ furnace, you can count on our team of experienced HVAC technicians to take care of them in a timely manner with a commercial HVAC service. We can perform every aspect of commercial HVAC repair, from inspecting broken furnaces to preventative furnace maintenance to avoid furnace problems that might pop up.

Issues that may indicate your furnace needs repair include:

Pilot light does not stay lit
Blower runs continuously
Reduced airflow
Heater blowing cold air
System cycling frequently from on to off
Moldy or unpleasant smell coming from vents

Commercial HVAC Installation

If your business’ heating or cooling system is old or not maintaining the building as it should anymore, it may be time to replace the unit. Design Aire specializes in the installation and replacement of all types of air conditioners and furnaces, and our technicians can get your business set up with a new unit in no time with a quality commercial HVAC system.

What if you don’t know whether your system needs replacing? No problem! Our knowledgeable technicians are familiar with and work with all brands and can help determine if it makes more sense to replace your equipment rather than repair it with an ac installation service. We take many factors into consideration when recommending a solution for your commercial HVAC systems, including the age of the unit, the size of the space it needs to cool or heat, and your budget, all to find the right upgraded system for your business.

We provide high-quality heating and cooling systems for major commercial builders in the St. Louis area.

“One of the best companies to work with. My own profession is in a service industry and so I very much appreciate all the positive things about Design Aire.
The install crew arrived right on time and took exactly how much time they said they would to complete the job. The work was done well, the crew cleaned up after themselves, and were very pleasant. Seth in the office was extremely in-tune to our needs and very responsive.
I would highly recommend Design Aire.”

“I was very impressed with Design Aire. They were timely and did an outstanding job with the installation of my new furnace. They had great communication and went above and beyond. I would highly recommend them to friends and family. Thank you so much Seth and Design Aire for making this an effortless transaction. VERY PLEASED!”
Jonny M.

“Design Aire sent a salesman to plan the system, and just a couple of days later sent the installers to remove the old system and install the new one. Everything happened when they said it would and the system performs as they said it would. All of the Design Aire staff were courteous, the work was performed efficiently and neatly, and they left the area cleaner than they found it. This is the second unit Design Aire has installed for us, and I have no need to look elsewhere.”
