Commercial systems run 10–14 hours a day. That is roughly double residential duty, and it means wear arrives faster, failures cost trading hours, and a repair that treats a symptom will be back before the season ends.
The Straight Answer
When a commercial system fails, the repair bill is rarely the expensive part. Staff working in a hot building, customers leaving, tenants calling, stock or equipment at risk — that is where the money goes, and it goes quickly.
Which is why we diagnose the whole system rather than replacing individual parts. Commercial equipment operating ten to fourteen hours daily accumulates wear far faster than residential, and a component swapped without finding what stressed it tends to fail again during the same cooling season — usually at a worse moment. Structured diagnostics cost a little more attention on the first visit and considerably less disruption afterwards.
Who We Look After
Where comfort complaints become productivity complaints, and where a warm afternoon is noticed by everyone at once.
Customer-facing spaces where an uncomfortable environment shortens visits and shows up in the day's takings.
Where stable temperature and humidity are a clinical requirement rather than a comfort preference.
High heat loads from kitchens combined with a dining room that has to stay comfortable regardless.
Where a cooling failure generates calls from every tenant simultaneously and lands on the manager.
Large volumes, wide temperature swings, and equipment or stock that may not tolerate either.
RTUs needing crane access, permits, and coordination well beyond a swap at ground level.
Systems past their service life with repeat failures, where the sensible answer has shifted to replacement.
Repair Diagnostics
Pressure testing and leak detection, since low charge is a symptom with a cause behind it.
Performance assessed properly — overload from extended runtime is a genuine commercial failure mode.
Electrical components tested and replaced where they are the cause rather than assumed.
Load tested and breakers inspected, because commercial draw exposes weaknesses residential never would.
Airflow checked and duct restrictions corrected, so the system is not fighting its own distribution.
Drain lines cleared and condensate managed — a blocked drain closes a business as effectively as a dead compressor.
Thermostat and building control system testing completes the picture, since on commercial sites the controls are as often the fault as the equipment.
Repeated failures on aging equipment usually cost more across a season than replacement does across its life. We will give you the arithmetic for your building rather than a preference for ours.
Replacement Projects
Commercial replacement covers more than the unit itself:
Replacing aging equipment improves capacity, cuts energy consumption, and stabilises performance through a long Florida cooling season.
Rooftop work is a project rather than a visit:
Getting this sequence right is what makes a system pass inspection and hold balanced airflow under continuous demand.
Oversized commercial systems short cycle and raise indoor humidity; undersized ones cannot hold comfort at peak occupancy. Correct sizing weighs building cooling load, equipment tonnage, occupancy heat load, electrical compatibility, efficiency options, and long-term operating cost:

Request Commercial ServiceCommercial Questions
We operate 24/7 emergency response, because a commercial cooling failure does not wait for business hours and neither does its cost. Call us and we will tell you honestly when we can be there rather than giving an optimistic estimate. Clients on maintenance agreements get priority scheduling, which matters most during the weeks when everyone is calling at once.
It depends on age, failure history, and what the repairs are costing you across a season — including the downtime, which is usually the larger number. A sound system with a specific fault is worth repairing. Equipment failing repeatedly near the end of its service life is usually costing more in disruption than replacement would across its life. We will show you that arithmetic for your building.
More coordination than mechanical work. Crane access has to be arranged, municipal permits approved and inspections scheduled, electrical panel capacity verified, load calculations completed, ductwork reconnected and airflow rebalanced, then refrigerant charged and performance tested. Planning that sequence properly is what keeps the project moving rather than stalling between trades — and what determines your actual downtime.
Runtime, mostly. Commercial systems frequently operate ten to fourteen hours a day under heavy occupancy loads, which accelerates wear compared with residential equipment doing far less. Add Florida's cooling season and components accumulate hours quickly. It is why commercial maintenance intervals are shorter and why diagnostics matter more — small faults compound faster.
Where the work allows, yes — and it is worth raising early, because it shapes how a project is planned. Some tasks can be done outside opening hours; crane lifts and inspections are constrained by permits and third parties, so those need scheduling around rather than simply moving. We will be straight about which parts are flexible and which are not.
Yes, and it is a common and expensive mistake. An oversized system satisfies the thermostat quickly then shuts off, which means short cycling, component wear, and poor humidity removal — in Florida that leaves a building cool and clammy. Undersized equipment cannot hold comfort at peak occupancy. Correct sizing comes from a load calculation on your building, not from matching the tonnage of whatever was there before.
