"I could not be more happy with the new Trane system. The sales person was very knowledgeable and helpful. He took lots of time explaining all the various options and did not try to talk me into something I did not want. The installers did a super job of installing the system in my older house. This new system, unlike my older one, is very even on temperature. Before, I was constantly adjusting the temp. Now it seems I never move the thermostat. Happy customer."
