AC Installationin Coral Gables, FL
New central air systems sized by load calculation, installed with a permit and commissioned properly.
AC Installation for Coral Gables buildings
Older Gables homes often have shallow attics, thick masonry walls and no obvious route for ductwork, so equipment choice matters more here than anywhere else we work. High-velocity small-duct systems and ductless mini splits let us cool original rooms without lowering ceilings. Larger estates usually run two to four separate systems, and we size each one to the part of the house it serves.
How an air conditioner is installed decides how it performs for the next fifteen years. Equipment that is too large cools quickly, shuts off and leaves the house clammy. Equipment that is too small never catches up in August. We size every system with a Manual J load calculation based on your home, and we never copy the tonnage printed on the old unit.
Every installation is permitted and inspected, the outdoor unit is anchored to meet South Florida's high-wind requirements, and the refrigerant charge is set by measurement.
Included in every installation
- Room-by-room load calculation
- New pad, hurricane tie-downs, disconnect and electrical whip
- New drain line with a float safety switch
- Line set flushed or replaced, pressure-tested and evacuated to 500 microns
- Mechanical permit and final inspection
- Manufacturer warranty registered in your name

AC Installation in Coral Gables: questions
What size air conditioner does my house need?
It depends on floor area, insulation, window area and orientation, ceiling height and duct condition. The rule of one ton per 500 square feet is often wrong for Florida homes. A load calculation gives the correct answer.
What efficiency rating is required in Florida?
New split-system air conditioners installed in Florida must meet the federal minimum for the Southeast region, which is 14.3 SEER2 for most residential sizes. Higher ratings cost more up front and use less electricity, which matters in a climate where the system runs most of the year.
Which refrigerant do new systems use?
Equipment manufactured from 2025 onward uses the newer refrigerants R-454B or R-32 in place of R-410A. They cannot be mixed with older refrigerants, which is one reason indoor and outdoor units are replaced together.
Is a permit required for HVAC work in Coral Gables?
Installing or replacing air conditioning equipment in Coral Gables requires a mechanical permit and a final inspection. Permits here are issued by the City of Coral Gables Development Services Department. Repairs, maintenance and cleaning do not need one. We file the paperwork and attend the inspection.
Can you install central air in a historic Coral Gables home?
Yes. Depending on the house we use a high-velocity small-duct system, ductless mini splits, or a conventional system routed through closets and soffits. If the home is a designated landmark or sits in a historic district, visible exterior equipment may need review by the city's Historic Preservation office, and we prepare the drawings for that.
Does Coral Gables have rules about where the outdoor unit goes?
The city's zoning code regulates the placement and screening of mechanical equipment, and it is stricter than most of Miami-Dade. We confirm setbacks and screening requirements before the permit is filed, so the installation passes inspection the first time.
