Installation, Repair & Maintenance — Broward & Palm Beach Counties
A rooftop unit (RTU) is a self-contained HVAC system mounted on top of a commercial building. The entire system — including the compressor, condenser, evaporator, and air handler — is housed in a single weatherproof cabinet on the roof. Conditioned air is then distributed through ductwork to the building below.
RTUs are the dominant choice for commercial buildings for good reason. They keep mechanical equipment off the floor, freeing up interior space, and simplify installation by eliminating the need for separate indoor and outdoor components. Maintenance and service is also more straightforward since technicians access everything from the roof.
Outside air enters the unit through the intake section. The refrigerant cycle removes heat from the air and pushes conditioned air through ductwork into the occupied space.
Rooftop units typically handle both cooling and heating in one package. Gas/electric models use a gas furnace for heat and electric cooling. Heat pump versions handle both modes with refrigerant, which makes them efficient in South Florida's mild winters.

RTUs are sized in tons of cooling capacity. Selecting the right size depends on square footage, building use, occupancy load, insulation, and local climate — not just the footprint of the space.
Ideal for single-tenant suites and smaller retail spaces. Fast installation and lower operating costs.
The most frequently specified range for South Florida commercial buildings. Handles heavy occupancy and kitchen loads.
Suitable for high-ceiling big-box retail and open office environments requiring strong airflow distribution.
High-capacity units for large open spaces with significant heat loads and demanding ventilation requirements.
Undersized units struggle to maintain temperature, run continuously, and fail prematurely. Oversized units short-cycle, leaving humidity problems behind. Proper load calculations before installation protect your investment.
Installing a commercial rooftop HVAC unit requires structural assessment, crane or lift coordination, refrigerant line connections, ductwork tie-ins, and electrical work. Our team handles the full scope — from equipment selection and permitting through to rigging, startup, and commissioning.
We work directly with general contractors on new commercial builds. Our team coordinates rooftop curb placement, ductwork layout, and electrical requirements early in the project, preventing costly change orders later.
If your existing RTU has reached the end of its service life, we can remove the old unit and install a modern, energy-efficient replacement on the same curb in most cases. We handle permitting, crane coordination, and startup testing.
Proper sizing requires a load calculation that accounts for square footage, ceiling height, insulation, occupancy, local climate, and equipment heat loads. We perform these calculations before recommending any equipment.
Commercial RTU work in South Florida requires permits. We handle the paperwork, coordinate with inspectors, and ensure everything is signed off before we close out a job.
After installation, we verify refrigerant charge, test airflow, check electrical connections, and confirm all controls and thermostats are working correctly before we leave the site.
Every project starts with a detailed written estimate covering equipment, labor, crane rental, and permit fees. You know the full cost before any work begins. Contact us to schedule a site assessment.
A failing RTU during business hours is a business problem. Employees can't work, customers leave, and perishables or equipment may be at risk. We respond quickly to commercial RTU service calls throughout South Florida.
Common issues we repair:
For compressor failures — often the most expensive repair — we'll walk you through your options and give you an honest recommendation on whether repair or replacement makes more financial sense.
Most RTU repairs are completed in a single visit. We stock commonly needed parts and can source others quickly for less common makes and models.
Older RTUs don't always need to be replaced when they have problems. But at some point, repair costs outpace the value of keeping the unit running. Hover each card to see what typically makes sense.
Our technicians will inspect your system and give you an honest assessment — repair costs explained and weighed against the benefits of a new unit.
Our technicians are trained on all major commercial rooftop unit manufacturers. We stock common replacement parts and can source components for most makes and models.
Rooftop units in South Florida run hard. Heat, humidity, salt air, and year-round operation put more wear on equipment than most parts of the country. Skipping maintenance is one of the fastest ways to shorten an RTU's service life.
Our HVAC maintenance plans include everything your RTU needs to stay efficient and reliable:
Regular maintenance catches small problems before they become emergency repairs and keeps your unit running efficiently — which directly reduces energy costs.
We size, install, and service rooftop units for all commercial applications throughout Broward and Palm Beach counties.
Most commercial RTUs last between 15 and 20 years with regular maintenance. Units in coastal South Florida environments may see shorter lifespans due to salt air corrosion, particularly on condenser coils.
Proper sizing requires a load calculation that accounts for your building's square footage, ceiling height, insulation, occupancy, local climate, and equipment heat loads. We perform these calculations before recommending any equipment.
Twice per year is the minimum — once before the heavy cooling season in spring and once in fall. High-use applications or coastal locations may benefit from quarterly visits.
Yes. We offer emergency commercial HVAC service for urgent situations. Contact our team to schedule an urgent service call.
In most cases, yes. We evaluate the existing curb during the site assessment and use a curb adapter if needed to match the new unit's dimensions to the existing opening.
Yes. Modern RTUs are available with high EER and SEER2 ratings. Variable speed compressors and economizers can significantly reduce energy costs in South Florida's climate. We can walk you through the options and help you evaluate the payback period.
