• Big D Mechanical exceeded our expectations! They fixed the problem, gave us all options, and didn’t break the bank! It is assuring to know that there are trustworthy companies out there and Big D is on the top of the list. Will definitely be using them in the future and highly recommend them!

• 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!

  Jessica P.★★★★★

• 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!

• Great company! Spoke with Jen and she was amazing, would highly recommend!

  John K.★★★★★

• 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.

• I would like to give a shoutout to Jennifer Stone for making what is usually a difficult process very easy. Change of seasons is coming soon so get your systems checked!

• 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!

  James R.★★★★★

• 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.

• Came out promptly, very professional and fair. Gave me all my options and gave a thorough explanation of each. Definitely my new go to HVAC company.

  Damien R.★★★★★

• 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!!!!

• 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!
