Reviews of local pros in Willis, Texas

Randy is always responsive and professional and does great work. Certain Air installed my HVAC years ago. If I ever need to reach out for a service call Randy gets back to me quickly and gets out to the house quickly as well. A pleasure to do business with.

First class work. Randy stays with the job. Very experienced. I have used Randy
at another company. Found out he started his own HVAC company a few years ago. It is great when you see nice things happen to nice people. Randy is one of those people. Knowledgeable hard working guys in the company.

This is the 2nd time I’ve used them, and they are the most honest and helpful people I’ve used. They’ve gone out of their way to make sure I got the best price for a part for my AC- saving me several thousand dollars by having me get the necessary part from somewhere else. I never was pushed to replace the whole system like many of the bigger corporate owned companies. Definitely recommend!

This is probably the best AC company if you are in Houston area! They were very professional and also gave me a fair and good price to change my condenser and coil. They also signed me up for the product lifetime warranty so I wouldn’t forget to do it. Thank you Trent. We will definitely use them as long as we living here.

Last year 2022 we were paying in the month of August $673.00 for the house electricity and another $93.00 for the garage.

Now for 2023 since Certain Air changed out our air-conditioning, we paid $298.36 for the house and $30.48 for the garage.

They were very professional laying matting down the hallway and entry. They were cautious to remove and haul off the old unit and anything out of the attic. No boxes for us to haul off.

They also installed a new thermostat in the hallway,. Everything runs much cooler and faster, to where I am comfortable running the air on 74 degrees. They put a new breaker box outside connected to the house. My husband poured the slab underneath the air conditioner.

He explained how to hose it down to keep sand, leaves and debris out of the air conditioner to make it run more efficiently and smoothly.

We thank them for the fantastic experience and great warranties on his products and services. I hope our air-conditioning never goes out again, but if it does Certain Air is who we will be calling. Thank you, Randy, for the wonderful experience. As nice as you were, we hope not to see you again under these conditions. (ha-ha) But will use and highly recommend your company to anyone who asks.

Highly recommend Certian Air. Used them this summer to replace my AC unit and coils, based on reference. Excellent service. Showed up for service call and repair at the exact time they said. Fair price. Needed them again for intermitent furnace issues. Rodney troubleshooted and fixed unit without part swapping. Again fast call-out (next day), exactly on time, quality work, and a fair price!! Highly recommend Randy and Rodney!
