Collin Air Conditioning

Collin Air and Heat runs as a family-owned HVAC outfit right in Plano, Texas. The Bullock family got it going in 1980 when John and Brian Bullock set out to handle heating and cooling work for local homeowners with straightforward honesty. Over four decades later the business still centers on that same approach, taking care of everything from basic service calls to bigger system jobs across the area where summers run hot and winters can turn cold without much warning. They stick to practical solutions that fit Plano houses and keep systems working through the Texas weather patterns.

Technicians handle air conditioning replacements and furnace swaps, including jobs where both get done at once and last customers twenty years or more. They respond fast to schedule visits for diagnosing AC and furnace problems, show up on time, explain the fix in plain terms, and finish the work without extra delays. Semi-annual maintenance packages help catch issues early on cooling and heating units, while some jobs include insulation upgrades right along with a full HVAC replacement to improve performance in older homes. Customers note the crews work efficiently on these tasks and keep prices in line with what gets done.

Homeowners keep coming back because the crew shows up quick, charges fair rates, and delivers solid results that hold up over time, with some families using them for fifteen years across moves in the area. Reviews highlight clear communication during repairs, professional handling of everything from routine checks to major installs, and a focus on getting systems right the first time instead of pushing unnecessary work. That pattern of reliable speed, quality workmanship, and honest pricing builds steady trust with Plano residents. DIRT Score 5.0 from 433 reviews on Finds.

“I had a good experience with Collin Air Conditioning. They responded quickly, arrived on time, and diagnosed the issue without wasting time. The technician explained the repair clearly and completed the work efficiently. The pricing seemed reasonable, and the overall service felt professional. I'd definitely consider using them again for future HVAC needs.”

“They have taken care of us. They are always quick to schedule and come out to help diagnose and resolve our AC/furnace issues. Their semi annual package is very helpful and worth the money. They have a long term customer in me.”

“We have used Collin Air for at least 15 years. First with our home in Plano and now in Fairview. They respond quickly and are very professional. Their price is fair and work superb.”

“This is one of the most impressive companies that we have ever had the “pleasure” of doing business with. They are not just about selling but about “building” a relationship that is built on trust and quality. Collin recently replaced our HVAC unit and upgraded our insulation. Each and everyone of their employees was likeminded in courtesy, professionalism, and quality. They cleaned as they worked, they were responsive to questions/concerns, timely and quick to respond to phone calls, questions, etc. we are so very grateful we found them and HIGHLY recommend them for whatever your HVAC needs may be. They know what they’re doing and take great pride in their work and services and aren’t just trying to upsell products/services. We are in our 70’s/80’s and they made this process so “easy” for us!!! Thank you Collin Air!”

“Collin reached out same day to connect. He repaired our system to get it running until we came up with a permanent solution.”
