0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.

Trane Equipment We Sell and Install
We work with a full range of Trane residential HVAC products. Trane offers multiple product lines at different price and efficiency points — from dependable entry-level equipment to premium variable-speed systems that deliver exceptional comfort and energy savings. Popular Trane lines we install in St. Louis homes include:
Trane XV and XL Series — high-efficiency, variable-speed air conditioners and heat pumps. See our AC installation and heat pump pages.
Trane XR Series — reliable single-stage and two-stage systems that balance performance and value
Trane XC and S9X2 Furnaces — high-efficiency gas furnaces for consistent, even heating through St. Louis winters. See our furnace installation page.
Trane S8X1 and XB Furnaces — dependable entry-level and mid-range heating options for budget-conscious homeowners
Why Trane?
Trane is one of the most recognized names in HVAC for a reason. Their equipment is engineered for durability and tested under extreme conditions. In a climate like St. Louis — where air conditioners run hard from May through September and furnaces carry a heavy load from November through March — equipment quality and reliability matter.
Trane also offers some of the most advanced variable-speed technology available, which translates to quieter operation, better humidity control, and lower monthly energy costs for homeowners who choose premium models.
We Also Service What We Sell
One of the advantages of working with Thomas Hoffmann Air Conditioning & Heating is that we are not just a sales and installation company. We are a full-service HVAC company that handles Trane AC repair, Trane furnace repair, and maintenance on the same equipment we install. When your system needs service in year three or year ten, you can call the same company that installed it — and we will know your system.
We service all Trane models, including systems we did not install, and we carry common Trane parts to reduce wait times on repairs.
Locally Owned — Not a National Chain
There are national HVAC companies that operate in St. Louis under local-sounding names. Thomas Hoffmann Air Conditioning & Heating is not one of them. We are a real local company — locally owned, locally operated, with technicians who live and work in the communities we serve. When you call us, you are talking to the company directly.
