Testimonials

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.

These guys are the best, hands-down. There is no one I’d give my business to after working with Big D. Outstanding work, great price and excellent service. They pay attention to the details and make the process smooth and seamless.

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!!!!

Wonderful service, prices, and honest service that is a rarity nowadays! So very happy with Big D Mechanical. I highly suggest them, they gave me a peace of mind during a stressful time.

Couldn’t be happier with the service we received! They showed up on time and were honest and direct. It’s hard to find workers like this these days!!

Great service! I highly recommend them as an HVAC contractor in North Dallas! Extremely professional and easy to contact.

Thank you Jared and your team!! Quick response to our needs, friendly and amazing service, also took time to explain new thermostat! Highly recommended!!

These guys are the best! Super friendly, honest, fair and responsible prices. Where they really excel is the service. Two times now they have rescued me, coming out the same day I called and getting the job done!

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!

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.
