We're glad you found us. There are hundreds of heating and air conditioning companies in the Greater St. Louis area, and they can all start to look pretty similar.

Even if you maintain your A/C unit for years, there will come a time you need to replace your system with a new one. Having a skilled technician manage both the installation and replacement of your air conditioner means you can depend on one professional to get the job done right the first time. At Design Aire, we pride ourselves on good work for a good price, and we stand by our values. We know you have many options throughout St. Louis and St. Charles for HVAC assistance, and we hope you'll choose us to replace and install your new A/C unit.

A heater is an investment that should last for 15 to 20 years. The key to prolonging the life of your HVAC system is performing annual preventative maintenance, which helps protect this valuable investment - Design Aire can help! You expect your heating system to deliver consistent indoor comfort year after year. However, you need to take active steps to keep it healthy - especially during those summer months when your furnace or heater remains relatively untouched. After all, you and your family don't want to be surprised when you finally kick it back on and nothing happens.

A dependable heater is a staple of any modern home in the winter. Once it reaches the end of its shelf life, however, your furnace will need to be replaced. This inevitable expense means you need a dependable furnace installer you can trust to put in a more up to date unit when the time comes, so why not rely on a company with proven success? For over 100 years, Design Aire has provided furnace repair, furnace maintenance, and furnace install and replacement throughout the St. Charles and St. Louis area.

Design Aire is not only the largest residential Trane dealer in St. Louis and St. Charles - we are the largest in the entire state of Missouri. What does that mean to you? Design Aire has more training and experience with Trane systems than any dealer in the area. We also receive quantity discounts on Trane equipment, so you receive the best equipment and installation at a reasonable price. Composed of three main components-an indoor unit consisting of a coil and a fan, an outdoor compressor unit and a remote control-most ductless split systems are connected by refrigerant lines and require no ductwork.

When cold weather sets in, you rely on your furnace to keep you warm throughout the season. However, if your furnace breaks and you are left without heat, your home can be uncomfortable in no time at all. If you have children, pets, or elderly occupying the space, it becomes even more critical to have your furnace repaired right away!
