DT Air Conditioning & Heating

DT Air Conditioning & Heating Inc runs a family-owned HVAC shop based in Plano, Texas since 2002. They cover heating and cooling jobs across the DFW area including Allen and nearby spots where Texas heat and sudden cold snaps wear out systems fast. Homeowners turn to them for straight fixes on units that quit during peak summer or for new setups when old furnaces and air handlers no longer cut it. The crew sticks to practical work that keeps indoor temps steady without extra layers of hassle.

They handle AC repairs, full system replacements, furnace maintenance, and duct sealing along with mini split installs and indoor air quality checks. Tech Dana has shown up for repeat customers over nearly a decade, arriving ready and sorting issues with clear attention to the details on each visit. Zee has stepped in on multiple calls where other outfits pushed full replacements or wall drilling for wiring, instead spotting a bad part or simple fix that got the unit running right again. One Plano job beat three other quotes, landed on the schedule quick, and included an airflow upgrade that evened out a room that stayed ten degrees hotter than the rest of the house.

Customers stick with the company because the techs show up on time, explain options without pressure, and deliver work that holds up under local weather. Reviews highlight honest second opinions that cut unnecessary costs, solid installs that fix uneven cooling or wiring problems fast, and follow-through that keeps systems reliable long after the truck leaves. Speed and quality come through every time along with fair pricing and direct talks on what actually needs fixing. DIRT Score 5.0 from 387 reviews on Finds.

“I have been working with Dana and his team at DT Air Conditioning for nearly a decade, and they have consistently delivered exceptional service. From the beginning, their professionalism and attention to detail have set them apart. They are always prompt, arriving on time and ready to work, which I greatly appreciate. One thing that stands out is the respect they show for your home. Every visit, they wear protective shoe coverings, demonstrating a level of courtesy that is often overlooked but highly valued. It’s clear they take pride not only in their work but also in how they treat their customers. DT Air Conditioning has handled several major projects for me over the years. They installed my furnace in 2016 and replaced my AC compressor and blower in 2020. Both experiences were seamless, and the quality of their work has proven outstanding—everything continues to run perfectly today. They always take time to explain the process and ensure I am comfortable with the work being done. I also rely on them for maintenance twice a year, which has helped keep my system performing efficiently and avoid unexpected issues. Their pricing is fair and transparent, offering excellent value for the level of service provided. Overall, I could not be happier with DT Air Conditioning. Their reliability, expertise, and customer-focused approach make them a company I highly recommend to anyone in need of HVAC services.”

“Exceptional Service and Unbelievable Honesty! I cannot recommend Zee from DT Air and Heat highly enough. I was recently told by a technician from a different company that my entire AC unit was dead and needed to be completely replaced. Facing a massive bill, I decided to get a second opinion from Zee—and thank goodness I did! Instead of pushing an expensive replacement, Zee took the time to properly diagnose the unit. He found the actual issue, repaired it efficiently, and saved me thousands of dollars. On top of the incredible repair job, Zee went completely above and beyond. He took the time to educate me on proper maintenance and care, giving me invaluable tips on optimal thermostat settings and explaining exactly when to keep the fan on "Auto" versus "On." He even filled an open gap around the duct going into the house and walked me through best practices for air filter maintenance. If that wasn't enough, he also got up into the attic to look at my second unit and fixed an overflow issue it was having. Zee is knowledgeable, thorough, honest, and professional. It is rare to find someone with this level of integrity in the industry. DT Air and Heat has earned a customer for life!”

“Got 3 quotes for a new HVAC unit and DT came out on top. They got me on the schedule quickly, came and installed the system, upgraded the air flow to my office which has been like 10 degrees hotter than the rest of the house since I've moved in, and everything is working great so far. Plano inspector even said the work was done well. It's pretty hard to find a reliable and fairly priced company these days as everyone marks their stuff up through the roof, but I feel DT treated me fairly, gave me a good price, and I'm satisfied with the experience. I'll be going to them again from now on.”

“Outstanding service! After two other companies insisted I needed to drill through my walls to run new wiring, DT Air Conditioning & Heating saved the day. Zee was courteous and quickly found the real issue: a simple part replacement. The AC has been running perfectly ever since. Highly recommend their honesty and expertise!”

“Had a great experiencing purchasing our replacement HVAC system with DT. Alan and Dana were great to work with - timely, knowledgeable, thorough. Their pricing was fair and in-line with expectations, and they helped us to obtain a helpful Oncor rebate that other companies did not seem to offer. The install process was smooth and we are enjoying our new American Standard system. Thank you!!”
