Mason and Chantz were the installers for our new Trane equipment. They were both very cordial and professional. A bit young, but they knew what they were doing. They worked very hard and were here from 8:30am to 6:00pm. They took their time and did a great job, explaining all my questions. The system is working super cool so far. We have only used Glenn Aire as heating and ac service since being in Granbury for 8 years now and have been very satisfied with their service.
