Testimonials
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!
Candice DraisWe 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!!!!
Will continue to use these guys for any needs that arrives. Jared is a great communicator and makes every effort to take care of the customer with absolute professionalism.

Great service! I highly recommend them as an HVAC contractor in North Dallas! Extremely professional and easy to contact.
I highly recommend B D Mechanical for all your commercial needs. The owner/partners have a combined 40+ years of experience. I manage over 150k sq ft and over the years they have proven to be responsive, honest and knowledgeable with their craft. Performing everything from basic maintenance to complex install jobs.
Jared with Big D Mechanical is extremely knowledgeable and a master at what he does. He came and took care of an issue 2 companies before were unable to fix. Jared dropped what he was doing on a Friday night and got my Ice Cream shop’s freezer back running before any product was lost. He was friendly, fair, and it was a pleasure working with him. I can’t recommend him enough.
