What some of our customers have to say

  • W. Franks

    First of all I can't thank you enough for working with me on our new install. Having chosen Trane units I feel as if I have high quality units in my new home. Your installers were top notch, and were out to seek my highest satisfaction. I also want to thank you for providing the option of using WiFi controlled thermostats. In today's time it is difficult to program exactly when we would be home having 3 kids. Using the WiFi app I can fully control any unit in my home at just a click from my smart phone, with only about a 2 sec delay. This in itself will save me $$. Again, I thank you for your service, and look forward to having you maintain my new investment."

    W. Franks, Home Owner at Midlothian
