A Trusted St. Peters, MO Heating & Cooling Contractor Since 1904

For over 100 years, customers in St. Peters and throughout our region have trusted our team at Design Aire with air conditioning and heating services. Having your HVAC system stop working can interrupt your plans and cause a lot of stress, but we do our best to take the stress out of the situation using our knowledge and training to repair, maintain and replace your system.

An efficient, high-performing air conditioner is essential to our Midwestern summers. However, if you find yourself having to double-check that your system is working or notice other problems, it’s time to have a tune-up. Schedule an appointment with one of our experienced technicians. We work with all makes and models of air conditioners and are the top Trane dealer in the Midwest. Come experience the difference!

Although winters in our region can be unpredictable, you still want to have a dependable furnace available whenever the chilly temperatures are getting too intense to bear. If your furnace has been working well, only to suddenly stop, or you observe other problems, it’s time to schedule an appointment for a technician to repair the problem. You’ll be back to warmer temperatures and a system that runs in the background like it once did, rather than being something you worry about before you know it.

Although no one wants their air conditioner to quit, it will happen sooner or later. Thankfully, our technicians understand these service calls can be stressful and stop at nothing to provide you the high-quality service you come to expect from our team.

Just as no one wants to be too hot, being too cold can also pose a problem when you expect your home to have a consistent temperature—preferably one that doesn’t cause you to bundle up the minute the temperatures outside drop! When your furnace reaches the end of its shelf life, having a more efficient, newer furnace installed can be a quick and painless process. Design Aire is committed to your satisfaction!

We offer not only a service you can rely on at any time but HVAC products designed to meet your needs. Keep your home at a comfortable temperature year-round or, if you’re building a new home, ask us about helping with your new construction project—we’re happy to help! We have been recognized for a number of service awards from both our peers and customers, so take advantage of what we have to offer.
