My air conditioner just stopped working in 100+ weather. Alex was at my house within an hour of my calling! He diligently worked on the system, but it was very old and unfortunately needed replacing. Alex and Collin were at my house just before 8am the next morning with my new unit and had it cooling before noon!

Collin, Andy and crew did a great job replacing a broken coil in my house. Taylor had been like a nail on Lennox's bed to get my warranty approved. The delay on the coil from Lennox is something they cannot avoid or do something about. And at the end when the coil arrived, Andy showed up bright and early at my house and start working. Five hours later my house is cool and clean like they were never here (Andy always brings a big vacuum in his truck to clean up after the job is done). Was using their service before and will continue to do so in the future. Very professional and highly recommended.

Andy combed the fins on the outside unit and they turned out fantastic! Several other companies I talked to refused to do it. He was extremely polite and very fast. Service: A/C system repair

Since my last review 2 weeks ago, my 24 year old HVAC system was ready for retirement. Of course I called Collin Air Conditioning & Heating. The proposal was completed and accepted within one day. The installation was stellar, as they brought many members of the team and completed it in one day. Everything from proposal to complete installation went without a hitch. Collin Air Conditioning & Heating has been my HVAC company for many years.
Never once has there ever been an area of concern. Their team members are always on time, professional, very knowledgeable about the work to be performed. I'm glad I took my own advice and called Collin Air--I wouldn't call anybody else!

Awesome customer service! Our requests are always turned around quickly so that business may continue as usual. Not every technician cares about that, but Collin AC does! Services: Thermostat repair, A/C system repair
