In 1904 our founder, Frank Fischer, started our family’s company with the motto, “Do a good job at a fair price and treat people right.” Those are simple words, but we try to live up to that every day. At Design Aire, we realize that you are the most important aspect of our service business. In every facet of our company, we illustrate that We Care about Our Customers. Whether you need an emergency repair, would like to take advantage of the benefits of our planned maintenance agreements, want a new high efficiency furnace or air conditioner installation, you will get the same great service from Design Aire. That is our commitment to you. If you are ever not 100% satisfied with the customer service we have provided, please contact us.
You are the key to the growth of our heating and air conditioning company, and we treat you as such. We believe that if you are perfectly pleased with your service or installation from us, you will tell your family and friends about Design Aire when they need a recommendation. That simple concept has worked for four generations and has earned us the title of “Best Heating and Cooling Company” from readers of the St. Louis Post-Dispatch, an A+ rating from the Better Business Bureau and multiple Angie’s List Super Service Awards.
