Commercial RTU Repair and Service in Utah
Packaged rooftop units, or RTUs, do the heavy lifting for most commercial buildings in Utah. A single rooftop unit combines cooling, heating, ventilation, and controls into one weatherproof package, which makes it efficient but also means a single failure can affect comfort across an entire zone. Flo Mechanical Solutions specializes in RTU repair and service, with the equipment knowledge and field experience to keep these complex units performing through Utah's demanding seasonal extremes.
RTUs combine multiple subsystems, and effective service requires fluency in all of them. On the cooling side, we diagnose compressors, refrigerant circuits, condenser coils, and condenser fan motors. On the heating side, we service gas heat sections, including ignition systems, gas valves, and heat exchangers, with careful attention to combustion safety. We also service the air side, addressing belts, bearings, blower motors, and airflow, and the economizer, where dampers and actuators control free cooling and ventilation. When economizers fail unnoticed, they quietly waste energy or compromise indoor air quality, so we verify their operation as part of comprehensive service.
Because RTUs operate exposed to the elements on the roof, they accumulate wear that regular maintenance can stay ahead of. Our preventive maintenance program cleans coils, verifies refrigerant charge, inspects electrical components and contactors, checks belts and bearings, tests economizer operation, and confirms safe combustion on gas units. This proactive approach extends equipment life, lowers operating costs, and dramatically reduces the emergency calls that disrupt your operations. When replacement becomes the better investment, we handle the crane, curb, and rigging logistics and install a properly sized unit.
As a locally owned mechanical contractor, our owner and technicians work directly on the rooftops alongside our customers' interests, providing honest assessments, written estimates, and responsive 24/7 service across Salt Lake City, West Valley City, Park City, Sandy, Provo, Ogden, Lehi, Draper, and surrounding markets. Whatever your rooftop units need, we are the RTU repair team Utah businesses rely on.

FAQ
FREQUENTLY ASKED QUESTIONS
Common questions from facility managers about commercial rooftop unit service in Utah.
With proper maintenance, most commercial RTUs last 15 to 20 years. Neglected units often fail much sooner. Regular service significantly extends equipment life and protects your investment.
We recommend at least two preventive maintenance visits per year, before the cooling and heating seasons. High-use or critical facilities often benefit from quarterly rooftop service.
An economizer uses outdoor air for free cooling when conditions allow, lowering energy costs and improving ventilation. Failed economizers often go unnoticed, wasting energy, so we test them during every service.
Yes. We coordinate crane, curb adapter, and rigging logistics and schedule changeouts to minimize impact on your operations, often completing replacements with little downtime.
Yes. Our technicians work on all major brands and tonnages, from small single-zone units to large packaged systems on commercial and industrial buildings.
Yes, especially on gas units. A cracked heat exchanger or combustion problem can pose serious safety risks, so we inspect for these hazards and address them promptly.
Yes. We provide 24/7 emergency RTU response across the Salt Lake City metro and statewide Utah, with priority for facilities where downtime is critical.
We serve the Salt Lake City metro and commercial markets across Utah, including West Valley City, Park City, Sandy, Provo, Ogden, Lehi, and Draper.
