Our story

A small shop in Washington, built one job at a time.

M&M Mechanical Inc. opened its doors in 1992. Washington was a much smaller town then—Telegraph Street had stoplights you could count on one hand, and the population of the entire valley was a fraction of what it is now.

The early years defined the company. Between my father, who started in the trade back in 1973 at the age of 20, and myself, starting at 18, we have well over half a century of combined hands-on experience right here in Southern Utah. By 1996, the business had grown enough that our family put up the current shop on Rio Virgin Drive. We've been operating out of it ever since. Same family. Same address. Same phone number that's been answered for over three decades.

Over the last thirty-plus years, we've worked on essentially every era of HVAC equipment in the region. We know the older R-22 split systems inside and out, just as comfortably as the modern variable-speed inverter units and ductless mini-splits going into custom homes across the valley this week. That deep well of experience is our actual product. When a technician walks into your mechanical room, they've likely seen your exact configuration before and know exactly how to handle it.

Most of our calls today come from repeat customers, their kids, and the neighbors they sent our way. That's not an accident. It's the result of decades of decisions about how to do honest work. We don't run salespeople on commission, we don't push memberships you don't need, and when a simple, inexpensive part will fix your system, that's exactly what we install.

Furthermore, we monitor our lines around the clock to ensure critical system breakdowns get priority attention when the summer heat peaks.

Plenty of HVAC companies have made a different choice. We'll keep making this one.

What we do

Commercial. Residential. Industrial.

Since 1992, our shop has been built on versatility. Over the last three decades, we've made sure our crew has the training and hands-on experience to handle a wide range of demands across the valley—whether that's a quick residential service call, a tenant improvement build-out for a local restaurant, or a heavy commercial rooftop replacement.

That diverse workload keeps our skills sharp. Working on commercial systems forces our team to stay current on complex rooftops and control systems, while our residential work keeps us connected to the local homeowners who built our business from day one. We handle each job with the same straightforward, practical approach.

Our standards

How we run the company.

The trade has changed a lot in three decades. A few of our principles haven't.

Licensed & insured in Utah

We're a Utah-licensed HVAC contractor, fully bonded and insured. Our installs pass inspection the first time because we follow code and we don't cut corners on rough-ins.

Manufacturer-trained technicians

Our techs hold current EPA 608 universal refrigerant certifications and ongoing factory training across Carrier, Trane, Mitsubishi, and the other major brands we install. The trade evolves; so does our team.

No commission salespeople

Nobody on our team earns a commission on selling you a system. Quotes come from the technician who looked at your equipment, not a closer in a polo shirt who was driven over after the diagnosis.

Plain-English explanations

If we recommend a part or a system, we'll explain why in language a non-HVAC person can follow. You should never feel rushed into a decision you don't understand.

Meet the team

A small crew that's been doing this a long time.

M&M is a small, tight-knit team: owners, lead technicians, install crew, and the office staff who route the trucks and answer the phones. We keep the company small on purpose. It's how we keep quality consistent across every job and how we keep institutional knowledge in the building instead of in a CRM.

Full bios for the owners and lead techs are coming soon. In the meantime, the best way to meet us is to call the shop and ask. Whoever answers will probably be the same person who picks up next time.
