An Energy Savings Agreement with ETR can Save You Time and Money.


Chances are you didn’t wake up this morning and decide to buy a new ac and heating system. As a homeowner, it’s the one thing you don’t ever plan on. What you can plan on is your system breaking late at night or on a weekend and that the repair will be a huge, unplanned out of pocket expense.

ETR and Trane now have a solution for homeowners and are excited to announce the Trane Unstoppable Comfort program to East Texas. For a simple monthly payment as low as $125 you get a new Trane high-efficiency complete system, a 10-year parts and labor warranty, and 10 years of bi-annual maintenance from ETR.

For 10 years you have peace of mind that your system is operating at peak performance and you have no additional out of pocket expense whatsoever. In many cases, the utility savings alone will offset your low monthly payment! Call ETR today for more information and to schedule your free estimate.

Remember, it’s hard to stop a Trane and now your new Trane system is truly "unstoppable”.
