Watch Francisco tell the story · 0:33
Why “Constant”? It starts with a C.
When Francisco was choosing a name for his company, he kept coming back to one letter: C — the first letter of his late father Carlos’ name. That letter became Constant Heating & Air.
It’s still a family business. When you call, you talk to people who treat your home like their own — weekdays, weekends and the hottest days of a Texas summer.

Francisco came out and he was on time and honest. He showed me the problem and gave me pricing before making repairs. As a single woman it’s hard to find people to trust.
One of my rooms wasn’t cooling properly. Francisco made all the necessary adjustments and now I am so happy with my air flow. He came back for the 2nd time as he promised… No extra charge. Fair prices.
Very responsive, fair pricing & honest team. Got my compressor replaced. Had a capacitor failure immediately right after and the team came and fixed it. Very happy with the service.
Fransisco and Daniel did an amazing job installing my unit, both are really nice and informational. I’ll be using them for my future HVAC needs again!
Very helpful, professional, knowledgeable and easy to communicate with throughout the entire process. The work was completed efficiently and with great attention to detail. Highly recommend!
Did an outstanding job replacing my house units! He was not only punctual but also incredibly professional throughout the entire process. Highly recommend!
Great work, responsive and reasonably priced! Francisco got the job done quick and correctly! I will be using them again in the future.
Very fast and reliable, communicated the whole process and I didn’t need to stand over his shoulder… Fair pricing, quick response, and amazing knowledge. Definitely the first guy I call when needing any and all HVAC work.
Highly recommend this AC company! If you need honest, quality work, this is the place to call.
