Three Decades of HVAC in Southern Utah

M&M Mechanical Inc. opened 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 St. George metro was a fraction of what it is now. The HVAC trade in Southern Utah was mostly a handful of family-run shops, and we were one of the smaller ones.

The early years were the kind of work that defined the company. Residential AC swaps in older neighborhoods, gas furnace installs in homes that had been heating with oil or wood, and the occasional commercial rooftop on a downtown St. George storefront. By 1996, we'd outgrown the original shop and built the current building on Rio Virgin Drive, the address still on every truck. The same family that put up that building still answers the phone.

Three decades later, we've worked on essentially every era of HVAC equipment that's ever been installed in Southern Utah. The 1970s gravity furnaces in old Washington Fields. The R-22 split systems we put in during the 90s and replaced with R-410A units in the 2010s. The modern variable-speed inverter units and ductless mini-splits going into custom homes in Kayenta and Desert Color this year. That long tail of experience is the actual product. When a tech walks into your mechanical room, they've probably seen the exact configuration before, because they probably installed it.

Most of our calls today come from repeat customers, their kids, and the people they sent our way. That's not an accident. It's the result of thirty years of decisions about how to do the work: decisions about not selling people what they don't need, about not running on commission, about answering the phone after hours when an AC fails in July.
