Commercial AC installation for Miami businesses
Commercial installs are planned around the building and the business: crane days, permits, opening hours and equipment that has to carry a kitchen or a full sales floor in August. We survey first and schedule the work so the business keeps running.

Updated October 2026
Commercial AC installation in Miami covers rooftop unit replacement, cooling for restaurants and kitchens, and new systems for tenant build-outs. Our Medley head office and SW 117th Ave service office survey the space, size the equipment from a load calculation that includes people, lighting and kitchen equipment, pull the Miami-Dade mechanical permit, and schedule the lift and install around business hours.
The job
What makes a commercial install different
A commercial load isn't just the building. Kitchens add enormous heat from cooking equipment and exhaust hoods pulling conditioned air out of the room; retail floors add lighting and customers; offices add computers and people. Sizing has to account for all of it, or the system will run flat out every afternoon.
The logistics matter as much as the equipment: roof structure and curbs, crane permits, tenant and landlord approvals, and a schedule that keeps the doors open.

Your options
Rooftop package unit or split system for a tenant space
| Rooftop package unit | Split system | |
|---|---|---|
| Where it goes | One unit on the roof curb | Indoor air handler plus outdoor condenser |
| Best for | Single-story retail and restaurants | Offices with a mechanical closet or ceiling space |
| Install logistics | Crane or lift, curb fit | Line set and drain routing indoors |
The existing building usually decides; we explain when changing types is worth the extra work.

What we see on this job
Rooftop unit replacement
Replacing a rooftop unit starts with the curb and the roof: whether the new unit fits the existing curb or needs an adapter, whether the roof around it is sound, and how the crane will reach it. We size the new unit from a current load calculation rather than the old nameplate, because tenants and uses change. The swap is scheduled for a morning when the business is closed or quiet, with a crane or lift booked, and the unit is anchored to Miami-Dade's wind requirements before start-up.

Restaurant and kitchen cooling
Restaurant kitchens are among the hardest spaces to cool: cooking equipment dumps heat, and exhaust hoods pull large volumes of air out of the building that has to be replaced. Without enough make-up air, the building goes negative, doors are hard to open and hot, humid outdoor air leaks in everywhere. We size the cooling for the dining room and kitchen loads, coordinate with the hood's make-up air, and keep the dining room comfortable while the line is running at full heat.
Tenant build-outs
A new tenant in a shell space or a renovated unit often needs new equipment, new duct or a redesign of what's there. We work from the landlord's requirements and the tenant's layout, coordinate with the general contractor on rough-in timing, and pull the mechanical permit so inspections don't hold up the opening date. Where existing rooftop units serve the space, we inspect them and tell the tenant honestly whether they're worth keeping or should be replaced before the lease starts.

Local conditions
Permits and warehouses on the northwest side
Our head office on NW 72nd Ave in Medley sits in the warehouse and distribution corridor northwest of Miami International Airport, which is where much of our commercial installation work is. Every replacement in Miami-Dade needs a mechanical permit with the equipment's AHRI numbers, and inspectors check that what's installed matches the permit, so the equipment is chosen and submitted before the crane is booked.
