Our two AC units had gone out during a very hot week and with three kids under eight we were suffering. Jose came out from DT mechanical, and was very professional and kind.

The technician shows up on time. He was fast and kept me informed of all his steps and even went out of his way to explain certain functions of my A/C. Highly recommend DT Mechcanical for your HVAC needs.

Jose arrived on time, was very polite and very knowledgeable. He explained how the AC works, performed a tune up and checked the registers to make sure the AC was working properly. Jose even changed our very high air filters. I will call DT again if I need help.

Great company, very friendly from the scheduling people to the HVAC Engineer. He came in, diagnosed the problem in about 15 minutes, ordered the part, and the next business day he was back with the correct part and had the heater up and running in about another 20 minutes. Thank you very much!
