Testimonials
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.

Great service! I highly recommend them as an HVAC contractor in North Dallas! Extremely professional and easy to contact.
The Partners of Big D Mechanical have provided services in several buildings I’ve occupied (commercial and residential). Every point of communication, service rendered, and commitment given has been nothing short of exemplary. The Partners exhibit the highest level of professionalism and I appreciate the honesty and unparalleled work ethic. The Big D Mechanical team delivers on every metric I expect as a client, with a strong emphasis on quality, urgency, value, and care. I would recommend Big D Mechanical without question.
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.
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.
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.
Excellent customer service! The team was very professional and the system was installed as promised. They arrived on time and cleaned up before they left. The thermostat was set up and they made sure we knew how to use it. Highly recommend!!
