Dilmak Services, Llc

Dilmak Services operates as a family-owned business based in Wilson County, Texas, with more than thirty years handling HVAC jobs around the San Antonio region. They concentrate on residential and commercial cooling and heating needs, including central AC systems, ductless mini splits, and full heater services. The outfit also covers plumbing tasks tied to HVAC like water heaters and softeners. Homeowners in Wilson County deal with tough Texas weather that demands reliable equipment, and this crew steps in for installs, repairs, and maintenance using solid brands such as Ruud and YORK.

Dilmak sends techs like Mike who shows up and gets systems running right, even after bad prior work from other companies that left units in rough shape. For a hair salon in the area, they got the AC back online quick with fair bids that beat out competitors while delivering strong results. Office staff like Sandie and Ashley keep things smooth on the phone and in person, treating customers like family from the first call. Another job involved fixing a botched install, sorting out the problems on site without dragging things out or adding extra costs.

Customers keep coming back because the work holds up strong, with responses that get techs on site fast for urgent fixes, prices that line up with the results, and clear talks from start to finish. Quality stands out highest in feedback, followed by how well they communicate and charge fairly. Speed comes in solid too for getting HVAC units back in action across Wilson County homes and shops.

“Excellent experience overall, easily one of the best service experiences I’ve ever had. From the very beginning, Mike and Sandie made me feel like family. Sandie has an incredible phone presence, and it’s even better in person. Mike was just as impressive, within five minutes of talking with him, I felt like I had known him for years. What really stood out is how genuine this team is. They’re down-to-earth, highly knowledgeable, and clearly focused on building real relationships rather than just completing a job. Every interaction felt personal, meaningful, and professional. The installation crew was exceptional, hardworking, humble, efficient, and respectful. Derek, in particular, stood out. He was straightforward, focused, and always took the time to answer any question without hesitation or judgment. The quality of workmanship was truly top-tier. I’ve never seen this level of care from any installer or service provider. The cleanliness during the removal of my old HVAC system was impressive, and the installation itself was almost artistic, every detail handled with precision and pride. It’s clear this team stands behind their work and takes ownership of everything they do. I not only purchased equipment through them, but I’ll absolutely be trusting them with all future maintenance and service needs. Without any reservation, I highly recommend Derek and Dilmak Heating and Air Conditioning to anyone looking to improve the comfort and quality of their home.”

“Our technician was great! Prompt, knowledgeable, and courteous. Found and issue and fixed it promptly. I also can’t say enough about Dilmak’s office as well. Ashley has been great!”

“Dilmak has been great helping get my unit running after a poor installation job from another company. It's so hard to fix others mistakes. I would never have a unit repaired or installed by anyone else in the future. Thanks Dilmak.”

“James did a great job checking out our AC system, doing a thorough inspection, making sure it was prepared for the hot summer. He let he know about a couple of things I needed to do to keep my system working great all summer.”
