What excellent service! John came out and fixed out AC during one of the hottest days this year. My unit went out twice, and the first time out they were able to get is back up and running with a minor fix, but I do not think we caught it in time. The damage to the unit was a bit more than we thought and the motor went out two weeks after the we replaced the start capacitor. It was not an issue for Big D and his Crew! John was right back out here the day that it went out and replaced the motor and a few other components to get us back up and running. I think we have a year left before it just will need to be replaced When it is time for a new AC unit, we are only going to Big D Mechanical for our HVAC needs!

A1 quality, experience & service

Awesome guys! Very knowledgeable and efficient! Took the time to explain the issues to me instead of blowing off my questions! Thank you!!! Highly recommend this company !!!

We had a time sensitive issue that was very complicated. We had another company out the day before and after hours of trying to get the new smart thermostat installed, they eventually gave up. We needed to switch out to a smart thermostat to get a lower kilowatt rate through our electric company. Then we reached out to Big D Mechanical and they were able to arrive within hours of calling them. The current wiring on our thermostat system made this more difficult. Cliff at Big D did an AMAZING job and never gave up! He is a true problem solver and we are thrilled to have our smart thermostat installed and working to be able to get the lower kilowatt rate through our electric company. SO GRATEFUL!!!⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ THANK YOU BIG D!!!!

All new unit replaced, quickly and professionally! Great service! Thanks again so much.
