So our AC went out this evening and everyone we called could not come out tonight. I suddenly remembered a friend posted about Big D Mechanical LLC where she works and gave it a shot. Within an hour of calling Josh was out and got us up and running quickly. I cannot recommend this company enough!

I can't say enough how good Big D Mechanical is! We had another company come out that said we need a new A/C after installing a control board. We wanted to get a second opinion and chose Big D Mechanical. Josh, came out on time, He was very honest and good at communicating the details. Our coils needed cleaning and a couple of cheap parts. He showed us the diagnostic and the A/C was operating and healthy again! Thank you Big D Mechanical and Josh for saving our old A/C! This is the only HVAC company I will use for now on!

Our upstairs has always felt humid and sticky. Jared knew exactly what the problem was. The AC unit our builder installed was too large for our space, and it was making the humidity level too high. Jared and his team did a great job installing a new unit. They were quick and professional and took care to put down tarps, protecting my carpet. It feels great upstairs now, and my daughter reported that her sleep is so much better. Plus, we ended up with a cute, energy-efficient AC unit.

Selling our home. Inspector dinged us for a couple issues. Called Jared and he fit us into their schedule quickly. Brian came out and talked me through the issues and completed his own inspection and repairs. VERY professional and will recommend Big D to anyone needing a competent and courteous HVAC company!

We recently had Big D Mechanical out for two separate HVAC services and were extremely pleased with the results. The first job involved customized ductwork and problem solving, which they completed efficiently and even faster than expected. The second service was even more impressive with the replacement of a difficult-to-source compressor. They were able to locate the part quickly and had it installed the very next day, which was a huge relief. Throughout both projects, the team was professional, knowledgeable, and very responsive. They took the time to clearly explain the issues and were happy to answer all of my questions—both before the work started and while it was in progress. Highly recommend them for anyone looking for honest and reliable HVAC service.

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!!!!
