Rooftop unit repair and replacement, system upgrades, and preventative contracts for offices, retail, restaurants, medical facilities, schools, municipalities, and multi-tenant buildings. Coordinated to keep your doors open while the work happens.
The Straight Answer
Commercial HVAC systems in Florida commonly run ten to fourteen hours a day under heavy occupancy load. That runtime accelerates wear on compressors, electrical components, and rooftop units far beyond anything a residential system experiences. The equipment is different, and so is the cost of getting it wrong.
The other difference is that the repair is only half the project. Rooftop work means crane scheduling, municipal permits and inspections, electrical panel capacity, and Florida wind-load anchoring requirements. A contractor who can diagnose but cannot coordinate leaves your building waiting — and for a restaurant, clinic, or retail floor, downtime is the actual expense, not the part.
What Extended Runtime Does
Compressor overload caused by extended operating hours is the most consequential commercial failure, and usually the end of a chain that began with a smaller fault left running.
Capacitors and contactors cycling all day, every day, wear far faster than residential equivalents. They are cheap parts whose failure stops a whole building.
Long line runs and rooftop exposure make commercial systems more prone to leaks. Refrigerant is never consumed in normal operation, so low charge always means a leak to find.
Heavy occupancy load and neglected filtration restrict airflow, which raises static pressure and forces the equipment to work harder for less cooling.
The Total Comfort Way
RTU assessment on site, covering cabinet condition, anchoring, and access — because what the repair needs is partly determined by how the equipment can be reached.
Compressor and condenser diagnostics with performance measurement, so the most expensive component in the system is condemned on evidence rather than assumption.
Refrigerant leak detection and repair rather than a recharge that buys a few weeks. On long commercial line runs, locating the leak is the work.
Electrical load testing, breaker panel inspection, and capacitor and contactor evaluation under operating conditions.
Airflow verification and duct system correction, because commercial cooling capacity is lost to distribution as readily as to equipment.
Thermostat and building control diagnostics, including how zones and schedules are actually configured versus how the building is used.
Two Paths
Where the equipment has service life left, targeted repair restores performance without a capital project:
Where breakdowns are frequent or equipment has reached end of service life, replacement is the more reliable long-term answer:
Upgrading aging equipment improves cooling capacity and reduces energy consumption across a long Florida cooling season.
The Half Nobody Quotes
An RTU replacement is a logistics project as much as a mechanical one. Proper planning is what keeps it from becoming three days of closure.
Projects finish with ductwork reconnection, airflow balancing, and system commissioning with performance verification — not just a unit set in place and switched on.
Commercial work is judged on predictability as much as capability. Five things belong in any commercial HVAC engagement:

Request A Site AssessmentCommercial Questions
Where the site and the scope allow it, yes — scheduling around operating hours is a core part of how we plan commercial projects, because downtime usually costs a business more than the repair does. Rooftop work involving crane placement has its own constraints, which is exactly why the logistics get planned before the date is set rather than after.
More than swapping equipment. It typically involves crane scheduling for placement, municipal permit approval and inspection coordination, electrical panel evaluation and any capacity upgrade the new unit requires, load calculations for correct sizing, ductwork reconnection and airflow balancing, and commissioning with performance verification before handover.
Runtime. Commercial systems in Florida commonly operate ten to fourteen hours a day under heavy occupancy load, which accelerates wear on compressors, capacitors, contactors, and rooftop cabinets. The same components that last years in a home are consumed far faster, which is why scheduled preventative maintenance pays back more clearly on commercial equipment.
Yes. Commercial rooftop work requires municipal permit approval and inspection coordination, and installations must satisfy Florida building codes including wind-load anchoring requirements. We prepare work to be inspection-ready rather than treating the inspection as a later problem.
Yes. Preventative maintenance contracts can be structured around multiple units or a portfolio of properties, which is how most property management companies and multi-site operators prefer to work. It also produces a service history per unit, which is what makes replacement planning a budget decision rather than an emergency.
