David Weckar Heating & Air Conditioning

David Weckar runs his own heating and air conditioning company out of Denton, Texas. He handles work across North Texas and the wider DFW area, focusing on both residential and commercial HVAC jobs. After finishing HVAC school he moved up to service manager at another local outfit before earning his state licenses in 1996 and starting this business. With more than twenty years in the trade he takes on new installs, repairs, and service calls for every major brand on houses, apartments, and multi-unit buildings. The outfit stays ready for big or small projects and keeps pricing competitive while offering free estimates and second opinions.

Weckar and his crew handle full installations on new construction or retrofit jobs, along with repairs on air conditioners, heat pumps, gas and electric systems, and hydronic setups. They also work on vent-a-hoods and large Macro Air units up to twenty-four feet across. One customer needed a complete new AC unit and the team made the swap straightforward, then returned quickly to sort a small follow-up issue. Another called for a motor replacement and the technicians arrived ahead of schedule, finished the job in under half an hour, and left the space clean. Long-term clients report steady service visits that keep multiple units running right without any outsourcing.

Homeowners in Denton keep calling because the work holds up, response times stay fast, and the crew explains options clearly before starting. They show up on time, finish what they promise, and treat every property with care whether the job takes twenty minutes or several days. Quality scores stay at the top because they fix the actual problem instead of pushing unnecessary replacements, and they handle everything from single-family homes to larger commercial spaces without cutting corners.
