Why Trane?
Trane is one of the most recognized HVAC names in the country — engineered for durability and tested in extreme conditions. In St. Louis, where AC runs hard May through September and furnaces work November through March, equipment quality and reliability matter more than they do in milder climates. Trane also makes some of the most advanced variable-speed technology on the market, which translates to quieter operation, better humidity control, and significantly lower energy bills on premium models.
Full-Service Trane
We Service What We Sell
One advantage of working with us: we’re not just sales and install. We’re 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’ll know your system. We service all Trane models including systems we didn’t install, and we carry common Trane parts to keep wait times short.

A Real Local Trane Dealer.
Several national HVAC companies operate in St. Louis under local-sounding names. We are not one of them. Thomas Hoffmann Air Conditioning & Heating is locally owned, locally operated, with technicians who live and work in the communities we serve. When you call us, you’re talking to the company directly — not a franchise call center, not an out-of-state owner.

Common Questions
Trane Dealer Questions, Answered.
Do you offer financing on Trane equipment?
Yes. We offer financing through Trane manufacturer programs and third-party lenders with multiple term lengths available. Call (314) 471-7625 and we’ll walk you through current programs and what you qualify for.
Do you service Trane systems you didn’t install?
Absolutely. We provide Trane AC repair and Trane furnace repair regardless of who installed the system. If your Trane needs service, call us — we know the equipment and we carry common parts to reduce wait times.
Can I get a Trane system quote without a sales visit?
For a basic range estimate, yes — call us with your home details and we can give you a ballpark. For an accurate installed price, we’ll need to see your home in person to run a proper Manual J load calculation and check your ductwork. Most estimates are completed quickly, with no obligation.
What warranty comes with a new Trane system?
Trane offers a limited manufacturer’s warranty on all residential equipment. Many systems include a 10-year parts warranty when registered within 60 days of installation. Premium variable-speed models often include longer warranties on the compressor and heat exchanger. We register every install for you.
Is Trane worth the price compared to other brands?
Trane is consistently ranked among the most reliable HVAC brands and holds up well in demanding climates like St. Louis. Whether Trane is right for your budget depends on your priorities. We’re happy to discuss it honestly — we install other brands too, and we’ll never push Trane on you if a different system fits better.
How long do Trane systems last?
A properly installed and maintained Trane AC typically lasts 15–20 years, a Trane gas furnace 18–25 years, and a Trane heat pump 12–15 years. Annual maintenance is the single biggest factor in actual system life — well-maintained Trane systems regularly outlast their warranty period.
Are Trane systems eligible for tax credits or rebates?
Many high-efficiency Trane systems qualify for federal tax credits under the Inflation Reduction Act, and Ameren Missouri occasionally offers utility rebates. Trane heat pumps generally have the largest available credits. We’ll show you exactly what your specific configuration qualifies for before you commit.
What’s the difference between Trane’s XV, XL, XR, XC, and XB lines?
Generally: XV is the premium variable-speed line (highest efficiency, quietest, best humidity control). XL and XC are high-efficiency two-stage. XR is reliable mid-tier single- or two-stage. S8X1 and XB are dependable entry-level. We’ll walk you through which line fits your home’s size, your comfort priorities, and your budget.
