An air conditioner that works on a daily basis is essential in the Midwest due to the extremely hot and humid summer days we experience regularly. If your formerly reliable A/C unit suddenly develops new problems, or if old problems continue to plague you, our technicians can perform a diagnostic and make the necessary repairs to your air conditioner. You’ll be back to cooler temperatures before you know it!

Just as having a working A/C unit is essential during hot summer days, a reliable furnace is also a necessity when winter suddenly sets into our area. No matter if you have a furnace that has worked for a long time that, out of nowhere, quits or you notice something “off” about your system, our technicians are here to help. They have the necessary know-how to improve your furnace and get everything back in working order before you know it.

Did your old A/C unit stop working without warning? Does the HVAC technician say it’s completely out of commission? We can help! Our technicians can provide the right equipment and experience to install a new unit that’s not only more reliable, but more efficient, too!

Our most valuable asset is our team, for it is their pride and dedication to get the job done efficiently. As a small, family-owned business, we are able to give you the personal attention you deserve.

Since 1904, thousands of people in Chesterfield have recognized Design Aire for our quality furnace repairs and HVAC products. Don’t believe us? Take a look at our many awards, including an accolade for being the #1 Trane Dealer in the Midwest for over 10 years.

Customer Testimonials

Seth was our salesperson. He listened to our needs and provided the right product at the right price. The installation team arrived on time and went right to work.They worked with confidence and professionalism.We appreciated the care in protecting our floors and even the choice of how they went up on the roof indicated that they really did care. This company did what they said they would and certainly has our vote of appreciation and gratitude. We will happily recommend Design Aire to anyone.

Ken L.

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.

Heather H.

Our new HVAC system was installed yesterday and we could not be happier. From quote to completion the process was great! 100% would recommend!

We have used Design Aire for both a new furnace two years ago and a new AC unit this summer. Everything was done very professionally and quickly. I would not hesitate to recommend them to anyone needing any type of HVAC work done.

We've used them for our old house and our new house. They are honest, friendly, professional and affordable. We felt lucky to find them.

Maddy R.

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.
