Commercial HVAC

Commercial AC Maintenance

Since 1964, Cortez has kept commercial air conditioning systems running across Florida through scheduled maintenance instead of surprise repairs. Hospitals, hotels, restaurants, retail centers, and manufacturing plants trust us with their commercial HVAC maintenance plans. Our technicians maintain rooftop units, package systems, and chillers from every major commercial brand.

Fixing it right the first time is also how we approach maintenance. We build commercial AC maintenance plans around your building, not a checklist. Regular rooftop unit maintenance and scheduled inspections keep your system running efficiently and your warranty intact. Don’t wait for a breakdown to call us.

Why Maintenance Matters

What a Commercial HVAC Maintenance Plan Should Cover

A commercial HVAC maintenance plan should cover more than a quick filter change. Coil cleaning, refrigerant checks, electrical connections, condensate drains, and airflow testing all affect how efficiently a system runs and how long it lasts. Skipping any of these on a commercial unit can let small problems turn into compressor failures, and most manufacturers’ warranties require documented maintenance to remain valid in the first place.

Why Commercial Clients Call Cortez

Six Decades of Commercial HVAC Maintenance in Florida

Cortez has kept commercial and industrial HVAC equipment running in Florida since 1964, on a maintenance schedule rather than a break-fix cycle. 

Our technicians know how Florida’s heat and salt air wear down equipment faster than in almost any other state, and we build maintenance plans around that reality. We’re licensed under Florida contractor license CAC1820470, and we maintain systems whether we installed them or not. 

Our Process

How Commercial AC Maintenance Works With Cortez

When you set up a commercial AC maintenance plan with Cortez, we start by walking your building and reviewing your equipment. Visit frequency depends on your equipment’s age, how the building is used, and any manufacturer requirements tied to your warranty.

At each visit, our technicians inspect coils, refrigerant levels, electrical connections, belts, and condensate drains, and clean or adjust whatever needs it. You’ll get a written report after every visit, including anything we think needs attention before it becomes a repair call.

If we find a problem during a maintenance visit, we’ll tell you honestly whether it’s worth fixing now or something to plan for. The goal of a maintenance plan is fewer surprises, not a sales pitch every time a technician is on site.

Put your HVAC on a maintenance schedule.

One call sets it up.

Who We work With
Frequently Asked Questions

Commercial AC Repair Questions We Hear Often

What does a commercial HVAC maintenance plan typically include?

A thorough plan covers coil cleaning, refrigerant level checks, electrical connection inspection, condensate drain clearing, belt and bearing checks, and airflow testing. What’s included depends on your equipment type and how the building is used, so we build the plan around your system. 

Most commercial equipment manufacturers require documented, regular maintenance to keep the warranty valid. We provide a written record of every visit, so you have the documentation if you ever need to file a warranty claim.

Most rooftop unit and package system visits take one to two hours per unit, depending on the equipment’s condition and how many units are on the property. We’ll give you a time estimate before scheduling.

Yes. We schedule maintenance visits around your operating hours whenever possible, including early mornings, evenings, and weekends for hospitals, hotels, and retail spaces that can’t have a technician on the roof during business hours.

A tune-up addresses your system once, at whatever condition it’s in that day. A maintenance contract sets a recurring schedule tied to your equipment’s needs, which catches problems consistently rather than only when something already feels off.
