Commercial HVAC Plano

I have had many experiences with this company from work to home and they are like no other out there. The A/C in my house went out and Andy was here within 30 minutes to rescue me. Everyone I have worked with is professional, knowledgeable, and just overall amazing. I will never use another company again. Keep up the great work!”

We called Collin Air Conditioning when we felt it was time for a new Carrier A/C + A/H 3.5 Ton Complete Unit. We love Collin Air because whether it’s been years or a shorter time since calling we are remembered and they know what was said at the last visit. There was not one problem or change in price or system and we feel they are so reliable, trustworthy, price competitive, professional and they cleaned up after the installation. We could not be happier with our new Air and Heat and know there will be no worries if it is a hot summer. We have used Collin Air since we moved to Plano in 1990 and have always been happy with their work. Great company to use!”

I called Collin Air with a mysterious furnace related issue. Our technician that arrived, Andy, was extremely timely, pleasant, and professional. He walked through a step-by-step diagnosis and after ONLY hearing the behavior of the furnace was able to quickly identify and solve our heating issue”

The Professionalism and Knowledge that Jimmy showed when he came by to Service our new unit is why I’m Grateful that we decided to go with Collin Air Conditioning! We would highly recommend this A/C company over the competition for its Professionalism, Knowledge and Customer service to my friends and family for sure!”

"Steve at Hesse AC and Heat was referred to me by a good friend. I was being given a run around by my Home warranty and AC repair contractor. Steve spent time with me on the phone, free of charge for some initial diagnosis. He was very patient and asked me the right questions to understand symptoms.  His diagnosis was spot on. When I signed him up, he did come in for an diagnosis and confirmed the issue. Peak of the summer, he was able to get his crew in to have my AC coil replaced within a couple of days. His and his crew’s work is very clean and of good quality, at a reasonable price.  I would recommend Steve / Hesse for your HVAC work anytime!!"

My property management company called Air Mechanix at 4:50 and they were at my house within two hours. Sadly it wasn’t an easy fix and a new compressor needed… MORE
