When It’s Time to Replace Your AC
- System is 12+ years old
- Repairs are starting to stack up
- Energy bills have climbed year over year
- Rooms have hot/cold spots that never go away
- Your unit still uses R-22 refrigerant
- Outdoor unit is rusty, loud, or leaking oil
If any two of these apply, it’s time for a free replacement estimate.
Proper Sizing: The Single Biggest Factor
An oversized AC short-cycles, never dehumidifies properly, and leaves your home clammy even though it’s cold. An undersized unit runs nonstop and still can’t keep up on a 95°F day. We perform a Manual J load calculation — accounting for your square footage, ceiling height, insulation, window orientation, and South Florida’s design temperature of 91°F — before we ever quote a tonnage.
SEER2 Ratings Explained (14–26)
SEER2 is the federal energy-efficiency rating. As of 2023, the Florida minimum is 15 SEER2.
- 15 SEER2 — Entry-level, single-stage, meets code. Best for budget replacements.
- 16–17 SEER2 — Two-stage; smoother operation, better humidity control.
- 18–20 SEER2 — Variable-speed inverter systems; 30%+ lower utility bills vs. 13 SEER.
- 21–26 SEER2 — Premium inverter heat pumps (Carrier Infinity, Trane XV, Daikin Fit). Quietest, most efficient, longest-lasting.
In South Florida, the payback on upgrading from 15 to 18 SEER2 is usually 4–6 years.

Coastal & Humidity Considerations
Homes east of US-1 — Jupiter, Juno, Palm Beach, Deerfield, Fort Lauderdale Beach, Aventura, Sunny Isles — deal with salt air that corrodes standard condenser coils in 5–7 years. We recommend and install coastal-grade units with e-coated coils (Carrier CoastalArmor, Rheem Sea Coast, Trane WeatherGuard) to triple outdoor unit life.
Frequently Asked Questions
How much does a new AC cost in South Florida?
Most 3-ton 15 SEER2 replacements run $7,500–$10,500 installed. Variable-speed 18–20 SEER2 heat pumps run $11,000–$16,000. Exact price depends on tonnage, ductwork, and brand. We give free in-home estimates.
How long does installation take?
Standard residential replacements finish in one day. Complex installs with ductwork modifications take two days.
What size AC do I need?
A general rule is 1 ton per 500–600 sq ft in Florida, but we never guess — we do a proper Manual J calc.
Do you handle the permit?
Yes. We pull the mechanical permit and coordinate inspection in every Palm Beach, Broward, and Miami-Dade municipality.

Our AC Installation Process — 6 Steps, Zero Surprises
- Free in-home consultation. We measure your home, inspect ductwork, review your utility bills, and identify hot spots. You get a written load calculation (Manual J) — not a guess.
- Three quote options. Good / better / best — with the tradeoffs explained. We show you projected utility savings vs. your current unit.
- Financing approval (optional). 0% APR up to $25,000 available with instant approval for qualified buyers.
- Professional installation (typically 1 day). Two licensed techs remove the old system, install new equipment, replace line set, reseal plenum, pull permit, and test airflow at every register.
- Commissioning report. We document refrigerant charge, superheat/subcool, airflow, and static pressure. You keep a copy for the warranty.
- 12-year parts + 2-year labor warranty. We register every system with the manufacturer and hand you the confirmation email before we leave.
When Should You Replace vs. Repair?
The honest math: if your AC is 10+ years old, uses R-22 refrigerant (phased out), or a single repair quote exceeds half the cost of a new system — replacement usually makes financial sense. Here’s the rule of thumb we share with every customer:
- Age × repair cost ≥ $5,000 — strongly consider replacement. Example: a 12-yr-old unit with a $500 repair = $6,000 “age-adjusted cost.”
- Using R-22 refrigerant — parts are increasingly expensive and scarce. Almost always worth replacing.
- Utility bill doubled in last 3 summers — efficiency has degraded. A 20 SEER2 unit can cut your cooling bill by 30-45%.
- Repeated compressor or coil failures — these are the most expensive parts. Two failures = time to replace.
