Family Owned & Operated — Mesa, AZ

Built by Arizonans.
For Arizona
Workers.

Freez Bros Rentals was born from a simple observation — Arizona workers were suffering in the heat while contractors scrambled to meet compliance requirements with inadequate solutions. We built something better. A fully equipped, climate-controlled safety trailer that actually solves both problems at once.

Derek Umphres
Owner & Operator — Freez Bros Rentals LLC

Derek built Freez Bros Rentals after watching Arizona job site crews endure brutal summer conditions without real solutions. Being an Arizona native from a blue collar family gave him a clear picture of what was missing — and the drive to fill that gap with something built right. Every trailer in the fleet reflects his commitment to reliability, crew dignity, and doing the job properly.

The Problem We Saw

Every Arizona summer, outdoor workers face 110°F+ job site temperatures with nothing more than a shade canopy and a cooler. Meanwhile, Phoenix Ordinance G-7483 mandates formal heat illness prevention plans — and most contractors are scrambling to comply with solutions that don't actually work.

💡

The Solution We Built

We built a 16ft towable climate-controlled trailer with everything a job site crew actually needs — 18,000 BTU cooling, whiteboard walls, seating for 8+, first aid, eye wash, lockers, microwave, and 50-amp generator power. One trailer. Full G-7483 compliance. Delivered to your site.

🚛

How We Operate

We tow the trailer to your job site, level it, connect power, confirm the AC is running, and hand you the keys. When your rental period ends, we pick it up. No setup crew needed on your end. No logistics headaches. Just a cool, compliant space ready when your crew walks in.

📈

Where We're Headed

We're expanding our fleet and our service area across Arizona. Construction, solar, mining, highway infrastructure, wildfire response — anywhere crews work outdoors in Arizona heat, a Freez Bros trailer belongs. This is just the beginning.

What We Stand For

The Values Behind
Every Rental.

🛡️

Crew Safety First

We didn't build this business to check a compliance box. We built it because Arizona workers deserve a real place to cool down — not a folding chair under a sun shade. Every feature in our trailer reflects that commitment.

🤝

Reliability You Can Count On

When we say we'll be there before your crew arrives — we mean it. On-time delivery, proper setup, and equipment that actually works when it matters most. Your job site can't afford surprises. Neither can we.

Exceptional Service

Family-owned means you deal with the people who built this business — not a call center. Questions get answered. Problems get solved. We're invested in your crew's safety the same way you are.

📋

Full Compliance

Phoenix Ordinance G-7483 isn't optional and we don't treat it like it is. Every rental satisfies every requirement — shade, rest area, first aid, eye wash, training space, and documentation surface. One trailer, zero gaps.

💪

Built for the Real Job Site

Our trailers go where your crew goes — remote desert solar sites, mountain highway corridors, urban construction zones. Generator compatible, towable with any half-ton, and built for the conditions Arizona actually has.

🏠

Arizona Through & Through

We're not a national chain that doesn't understand Arizona summers. We live here. We built this here. We serve here. When you call Freez Bros, you're talking to someone who knows exactly what 110°F on a job site feels like.

Why This Matters in Arizona

The Heat Here Is
Not Like Anywhere Else.

Arizona doesn't have warm summers — it has lethal ones. The Phoenix metro regularly records the highest outdoor worker heat illness rates in the country. Heat illness is the #1 preventable cause of death in construction nationally, and Arizona's conditions push that risk further than almost any other state. Freez Bros exists because the existing solutions — shade canopies, coolers, and water jugs — simply are not enough. Our trailers drop interior temperatures by 40°F or more within minutes of powering up. That's not a comfort upgrade. That's a life safety system.
