Replacing an air conditioner in South Florida is not just a matter of matching the old unit's tonnage. The right system has to handle our heat and our humidity, meet current efficiency rules, pass a city or county permit inspection, and fit the space you actually have, whether that is an attic, a garage closet or a condo mechanical room.
Sunshine State HVAC installs and replaces central AC systems for homes and light commercial spaces across Broward, Palm Beach and Miami Dade counties. Every installation is performed by licensed HVAC technicians working under a Florida licensed contractor, and every quote is clear and complete before work begins.
We work with all major brands and help you compare system types and efficiency levels based on how you live, not on what is easiest to sell. Call (954) 800-2561 or use the Book an Appointment form to schedule an in home assessment.
When it is time to replace your AC
Age is one signal, but condition matters more. Systems in South Florida work hard all year, and by the time a unit is well into its second decade it often has corroded coils, worn motors and declining efficiency. If yours still runs on R22 refrigerant, any major repair becomes harder to justify.
Repeated breakdowns are another clear sign. If you have paid for several repairs in the past couple of years, or a technician has told you the compressor or evaporator coil is failing, putting that money toward a new system is often the better long term move.
Comfort problems count too. Rooms that never cool down, a house that feels clammy even when the thermostat is satisfied, and FPL bills that keep creeping up all suggest the system is no longer matched to your home or is no longer performing like it should.
Planning ahead also helps. Replacing a struggling system in the spring, before peak demand, gives you time to compare options, get association approval if you need it and schedule the install on your terms instead of in the middle of a July breakdown.
Sizing the system for your home
Bigger is not better with air conditioning. An oversized system cools the air quickly and shuts off before it has removed enough moisture, which leaves you with a cold but damp house. In South Florida that can lead to musty smells and mold.
Proper sizing looks at the home's square footage along with insulation, window size and direction, ceiling height, sun exposure and the condition of the ductwork. A west facing home in Weston with large sliding doors has a different load than a shaded Coral Springs house of the same size.
We also check whether the existing ducts can actually carry the airflow a new system needs. Pairing new equipment with undersized or leaking ducts wastes the upgrade. If ducts need work, our air duct cleaning and repair team can address it as part of the project.
SEER2, refrigerants and efficiency rules
Since 2023, new systems in the Southeast must meet minimum SEER2 efficiency ratings, a newer testing standard that better reflects real world conditions. Higher SEER2 systems cost more upfront but use less electricity, which adds up quickly given how many hours a South Florida AC runs each year.
Refrigerants have changed as well. R22 was phased out years ago, and R410A is now being replaced in new equipment by lower impact refrigerants such as R454B. A new system on a current refrigerant will be easier and less expensive to service for years to come.
We explain the efficiency tiers in plain terms, including where variable speed and two stage equipment helps with humidity control. You choose the level that fits your budget and how long you plan to stay in the home.
Choosing the right type of system
Most South Florida homes use a split system, with a condenser outside and an air handler inside. That is usually the most straightforward replacement when the existing layout works well.
A heat pump is a strong option here because it provides efficient cooling plus heat for the handful of cool nights we get each winter, without a separate heating system. You can read more on our heat pump services page.
Packaged units, which put everything in one cabinet outdoors or on a roof, are common in some older homes and light commercial buildings. For additions, garages or homes without ductwork, a ductless mini split may be the better fit. We will lay out which options make sense for your property.
Permits, inspections and code requirements
AC replacements in Florida require a mechanical permit from your city or county building department. We pull the permit, schedule the inspection, and make sure the installation meets current code.
Code items commonly checked include proper electrical disconnects, refrigerant line insulation, condensate drainage with a secondary safety switch or pan, and secure anchoring of the outdoor unit. Hurricane tie downs are required for condensers in South Florida, and they matter when storm season arrives.
Skipping the permit can create problems when you sell the home or file an insurance claim after a storm. A permitted, inspected installation gives you a clean record that the work was done right.
What drives the cost of a new AC system
The biggest factors are system size, efficiency level and type of equipment. A higher SEER2 variable speed system costs more than a single stage unit of the same tonnage, though it will typically cost less to operate.
Installation conditions matter as well. Replacing a straightforward garage closet system differs from an attic replacement with tight access, a rooftop condenser in a condo building, or a job that needs new ductwork, electrical upgrades or a relocated drain line.
Permit fees, crane access for rooftop units and any required duct or electrical modifications also factor in. We put all of it into a single clear quote before work begins, so you know exactly what you are approving.
It also helps to think about total cost over time rather than the install price alone. A system that runs fewer hours to hold the same temperature and controls humidity better can make a real difference on monthly FPL bills over the years you own it.
Condo and HOA approval for new systems
Most condominium associations require approval before an AC replacement, and many have specific rules about where the condenser can sit, what size it can be and what hours contractors can work. Some buildings also ask for a copy of the contractor license and the permit before work starts.
In single family HOA communities, replacing a condenser in the same location is often straightforward, but moving it, changing its size or adding a new pad may need architectural review. Checking early avoids delays on installation day.
We can provide the equipment details and documentation your association typically asks for so you can submit the request. Letting us know about building rules during the assessment keeps the project on schedule.
What installation day looks like
The crew starts by protecting floors and the work area, then recovers refrigerant from the old system before disconnecting and removing it. The old equipment is hauled away.
The new air handler and condenser are set, refrigerant lines and electrical are connected, and the condensate drain and safety switch are installed. The system is pressure tested and evacuated to remove moisture before it is charged and started.
Before leaving, the technician tests cooling performance, checks drainage and thermostat operation, and shows you how to change the filter and use any new controls. The permit inspection is scheduled afterward with the building department.
AC replacement FAQs
How long does a replacement take? Most standard residential replacements are completed in a single day. Rooftop condo units, duct modifications or electrical upgrades can extend that.
Can I keep my existing ductwork? Often yes, if it is in good condition and sized correctly. We inspect it during the assessment and tell you honestly if it needs work.
How do I get a quote? Book an appointment for an in home assessment. A licensed technician measures, inspects and gives you a clear written quote before anything is scheduled.
Start with an in home assessment
Replacement quotes are never done blind over the phone. A licensed technician visits, looks at your current equipment, ductwork, electrical and drainage, and asks how the house feels room by room. That visit is what lets us recommend a system that actually fits instead of simply matching the old label.
Side by Side options, one clear price each
You will usually see more than one option, such as a standard efficiency system and a higher efficiency variable speed system, each priced as a complete job. Every quote spells out the equipment, permit and installation work so you can compare apples to apples and choose without pressure.
Scheduling around your home
Once you approve, we coordinate the install date with you and, if needed, with your condo management or HOA. We handle the permit paperwork and keep you updated on the inspection so the only thing you have to do is enjoy a cooler, drier house.
