Commercial AC Replacement
Cortez has installed and replaced commercial air conditioning equipment throughout Florida since 1964.
Our crews handle everything from rooftop units to industrial chillers. When a system is past the point of reliable repair, we walk you through your commercial AC replacement options. Chiller replacement, package unit swaps, and full rooftop changeouts all get the same approach.
We size new equipment to how your building operates today, not just to match what’s coming out. Then we install it the same way we handle every call: getting it right the first time.
Signs It's Time for Commercial AC Replacement
Most commercial rooftop units and package systems have a useful life of 15 to 20 years, and chillers often run longer with good maintenance. Equipment nearing that age is usually cheaper to replace than to keep patching. The same goes for units running on a phased-out refrigerant, or ones that need more than one or two repair calls in a season. A commercial AC replacement done on your schedule almost always costs less than an emergency swap after a full breakdown.
Rooftop Unit (RTU) Replacement
Full changeouts for RTUs that have reached the end of their service life, sized to your building’s real load.
Package System Replacement
New packaged units for retail, restaurant, and small commercial spaces, installed with minimal disruption.
Chiller Replacement
Chiller replacement for air-cooled and water-cooled systems, including the piping and controls work that comes with it.
Retrofit & Change-Out Planning
Phased replacement plans for multi-unit properties that can’t take every system offline at once.
Six Decades of Commercial HVAC Replacement in Florida
Cortez has sized and installed commercial HVAC equipment across Florida since 1964, and that work is covered under Florida contractor license CAC1820470. We don’t push replacement before it makes sense, and we don’t let you keep paying to repair something that’s already lost the argument on cost.
How Commercial AC Replacement Works With Cortez
A commercial AC replacement starts with a site visit, not a phone quote. We measure your space, check ductwork and electrical capacity, and confirm what your building actually needs before we recommend equipment.
From there, we give you a written quote that breaks down commercial HVAC replacement cost by equipment, labor, and any electrical or structural work the swap requires. You’ll know what you’re paying for before anything gets ordered.
Installation is scheduled to minimize downtime, including nights, weekends, or a phased approach across multiple units when a building can’t go without cooling. Once the new system is running, we test it under load and walk you through what has changed.

Commercial AC Repair Questions We Hear Often
How much does commercial AC replacement cost?
Cost depends on equipment type, size, and any electrical or structural work the installation requires. Chiller replacement costs more than a single-package unit swap, and multi-unit rooftop projects scale with the number of units that need to come out. We give you a written quote after a site visit, not a number pulled from a price list.
How long does a commercial AC replacement take to install?
A single rooftop unit or package system swap often takes one to two days. Chiller replacement and multi-unit projects take longer, depending on crane access, ductwork changes, and the number of systems involved.
Can you replace one unit while keeping the rest of the building cooled?
Yes, in most multi-zone buildings. We plan replacements zone by zone or unit by unit whenever the property layout allows it, so the rest of the building stays comfortable during the swap.
What happens to the refrigerant in my old chiller or unit during replacement?
We recover and dispose of old refrigerant according to EPA requirements, which matters most for older equipment running refrigerants that have since been phased out.
Is it better to replace with the same size unit or upgrade capacity?
It depends on how your building’s use has changed since the original system was sized. We run a load calculation before recommending anything, since matching old capacity assumes nothing has changed, and that’s not always true.
