Current Trane Financing Offer
TCS SELECT Exclusive
12-Year Parts Warranty, 2 Years Longer Than Standard Trane Dealers
As a Trane TCS SELECT Comfort Specialist, I register every qualifying system for a 12-year parts warranty at no extra cost to you. Standard Trane dealers only get you 10 years. That two-year difference can be worth several hundred dollars if a compressor or coil goes out in year 11 or 12, it’s one of the real, concrete reasons the TCS SELECT tier matters for you as a customer.
As a Trane TCS SELECT Comfort Specialist, I offer 0% APR promotional financing through Synchrony on qualifying Trane HVAC systems, subject to credit approval. It makes a high-efficiency system a lot easier to budget without the big upfront cost. Call 405-375-4822 and ask me for current terms.


Subject to credit approval through Synchrony. Equal monthly payments required. Promotional financing on qualifying Trane equipment only. Ask for current terms when you call.
