Welch Air Conditioning Company

Welch Air Conditioning Company handles HVAC work across Plano, Texas and the wider North Texas area. The outfit got started in 2017 when Tim Welch, Nick Laughner, and Brandi Stefanski teamed up to focus on mechanical contracting for homes and buildings in the DFW metroplex. Their crew carries experience from big projects like school renovations and government buildings, but they apply the same approach to residential jobs. The goal stays simple: deliver solid performance at a fair price while building steady ties with owners and other contractors in the region.

The company installs complete new HVAC units and handles service calls on existing systems. Nick often shows up the same day for quotes and keeps costs several thousand dollars below what other outfits charge. One homeowner needed a full replacement and the crew arrived on time, walked through every step, and finished the job without issues. Another called for AC service on an intermittent unit and after the visit the system ran stronger than before. Technicians respond fast, even outside regular hours, and they throw in extras like free maintenance checks to keep things running right through the Texas heat.

Customers keep coming back because the work stays reliable and the pricing beats the competition without any runaround. Reviews highlight how the team shows up when promised, explains repairs in plain terms, and gets units fixed or replaced the next day. Homeowners note the friendly attitude from the whole crew and the way prices stay thousands lower while quality holds up on both new installs and routine service. That consistent record on speed, clear talk, and value adds up. DIRT Score 5.0 from 141 reviews on Finds.

“Welch’s Heating & Air did an incredible job! We just had a whole new unit installed, and I couldn’t be happier with the entire experience. The team from Welch’s was professional, friendly, and extremely knowledgeable. They showed up on time, explained everything clearly, and handled the installation with real care and pride in their work. They were respectful of our home, worked efficiently, and even worked wonderfully around our animals—which I really appreciated. They made sure the system was running perfectly before they left, and the difference in comfort is amazing already. If you’re looking for trustworthy, honest, high-quality HVAC service, Welch’s is absolutely the place to call. Highly recommend them for any heating or cooling needs!”

“After getting a quote that seemed much too high from another company, Nick came out same day to look. His quote was several thousand less than the other one! He took the time to listen and make sure I felt comfortable without pressuring me into anything. They were out the next day to complete the work and did a wonderful job. I'm definitely switching to Welch for all future HVAC work!”

“Best find for Heating/AC service !!!! Welch serviced my AC on 6/2/26. It now works better than it ever has !!!! I rate them A+, you won't be disappointed !!!! My ac was working intermittently and needed serviced. I wanted to select a small local company, not a large corporate company. Luckily I selected Welch heating and air. The appointment was at 1pm Tuesday, they arrived exactly at 1pm. The technicians Rob and Chris, started working on it immediately. They diagnosed, then fixed the ac and were testing it in about 27 minutes. The ac works better now than it has in the last 5 years. Welch Heating and Air was prompt, talented, efficient, friendly. Wish I had Welch service it sooner.!!! Thanks Welch !!! Impressed with your work, and will call next time too.”

“Nick and his company were recommended to us by a friend and now we see why. 1) Services are $10-15k cheaper for high quality appliances. 2) His entire team is extremely professional and friendly, often responding in less than 5 minutes and sometimes during off hours. 3) They even offered complimentary service checks every 6 mo as part of warranty. Would rely on them time and time again in the future!”

“Rob and Robbie came to my house on time and were very professional and friendly. They were able to answer all my questions and spent time going over the information for the thermostat they installed. I would strongly recommend Welch Heating and Air Conditioning to anyone.”
