About
At GrandAir Mechanical, I take pride in providing honest, reliable HVAC service and doing the job right the first time. I have hands-on experience diagnosing, repairing, maintaining, and installing a wide variety of heating and cooling systems.
I believe in explaining the problem clearly, giving customers straightforward options, and never recommending work that isn’t needed. Whether it’s a simple repair, maintenance, or a more complicated HVAC issue, I treat every home and system like it were my own.
My goal is simple: quality work, fair pricing, and making sure you’re comfortable with the service you receive.

Gonzalo came out to access my AC unit. He was very professional and thorough. He explained everything very well and put things in terms I could understand. He was very responsive. I didn't feel like I was getting duped. He was honest. I will use him in the future and also refer him to others!
