Why homeowners choose us

We Treat Your Home Like It's Ours

There are plenty of HVAC companies out there. Here's why our customers keep coming back — and sending their friends.

Real People, Not a Call Center

When you call Mendoza's, you're talking to the people who'll actually do the work. Martin Sr. or Jr. will answer, listen, and show up. No middlemen, no games.

Straight-Up Pricing

We'll tell you what it costs before we start. No hidden fees, no "well, while we're here..." upsells. If we wouldn't pay for it in our own home, we won't recommend it for yours.

40+ Years of Know-How

Between father and son, we've fixed just about every HVAC problem the Gulf Coast can throw at you. Heat waves, humidity, coastal wear — we've seen it all.

Fast When It Matters

AC dies at 2 AM in July? That's what our 24/7 emergency line is for. We know you can't wait — and we won't make you.

American Standard Quality

We're an authorized American Standard dealer because we only install equipment we'd put in our own homes. Top-tier reliability, backed by real warranties.

Residential & Commercial

From single-family homes to local businesses, we handle it all. Same honest service, same fair prices — just scaled to fit your space.

Our story

A Father, a Son, and a Whole Lot of HVAC

Mendoza's Air Conditioning & Heating isn't a franchise. We're not backed by investors or run by a board. It's just us — Martin Sr. and Martin Jr. — a father and son who genuinely care about doing good work for our neighbors.

Martin Sr. has been in the HVAC trade for decades. Martin Jr. grew up learning the business from the ground up — literally riding along on service calls before he could drive. Together, they bring 40+ years of hands-on experience to every job.

Proud partner

Authorized American Standard Dealer

We chose American Standard because they build HVAC equipment the way we do business — reliable, efficient, and built to last. It's the brand we'd put in our own homes, and it's what we recommend for yours.
