Commercial HVAC
Florida’s heat and salt air wear down commercial HVAC equipment faster than in almost any other state. Coastal humidity gets into coils and framework, corrodes components, and leads to mold, mildew, and indoor air quality problems that show up long before the equipment fails outright. Cortez has worked as a commercial HVAC contractor in Florida since 1964, and we see this pattern in hospitals, hotels, retail centers, and manufacturing plants across the region.
When a system starts to break down, the owner pays twice: once for repairs and again for utility costs that climb as the equipment loses efficiency. We see this most often in new construction, where the equipment with the lowest up-front cost ends up costing the most once the building is occupied and the system runs full-time.
At Cortez, we understand how commercial building systems work and how to turn an inefficient, expensive air conditioning system into a dependable, cost-effective one. We’ve made our name as the commercial HVAC contractor Florida calls when the job is bigger than most contractors can handle, and for fixing it right the first time.

Commercial HVAC Questions We Hear Often
How often should a commercial HVAC system be serviced?
Most commercial systems need inspection and tune-up at least twice a year, once before cooling season and once before heating season. Facilities with heavy use, such as manufacturing plants or hospitals, often require quarterly service to keep warranties valid and avoid unplanned downtime.
What's the difference between repairing and replacing an aging rooftop unit?
Repair makes sense when a unit is under 10 years old, and the fix addresses an isolated problem. Once repair costs start approaching 30 to 50 percent of replacement cost, or a unit is nearing the end of its expected life, replacement usually saves more money over the following years through efficiency gains alone.
Do you work on buildings that are still occupied?
Yes. We schedule installation and major repair work around a facility’s operating hours whenever possible, including nights and weekends for hospitals, hotels, and retail spaces that can’t shut down.
How fast can you respond to an emergency HVAC failure?
We offer 24/7 emergency response for commercial accounts across southwest Florida. Response time depends on location and system type, and our team prioritizes calls where a shutdown affects patient care, guest comfort, or a production line.
Do you service equipment you didn't originally install?
Yes. We maintain, repair, and upgrade HVAC systems regardless of who installed them, including systems from other contractors and equipment left behind by a previous building owner.
