AfterAC Replacement in Fort Lauderdale, FL
AC replacement in Fort Lauderdale typically runs between $5,800 and $12,400 for a complete system, depending on the size of your home and the efficiency rating you choose. A trained technician can usually swap out an old system in a single day, and at Cold Harbour Heating and Air Fort Lauderdale we put the full price in writing before any work begins. If your current unit is limping through another sweltering summer and you’re tired of paying for repairs that don’t stick, explore our AC repair installation services or call us at (754) 354-7289 for a free estimate.
We’re an independently owned and operated member of the Kingswell network, which means we answer to a written standard, not a corporate slogan. We’ve been replacing and repairing AC systems for Fort Lauderdale homeowners since 2003, and we work on all the major brands, including AC Repair & Installation in Fort Lauderdale jobs involving York, Daikin, and Bryant equipment. When a replacement is the right call, we’ll tell you plainly. When a repair makes more sense, we’ll tell you that too.
The name Cold Harbour comes from the old roadside shelters where travelers waited out rough weather. That’s the job here: making sure your home is the place you wait out a Fort Lauderdale August in comfort, not in front of a box fan.
When You Need AC Replacement
Not every failing AC needs to be replaced. But there’s a point where continued repairs stop making financial sense, and knowing that point in Fort Lauderdale’s climate matters. Here’s what pushes most homeowners toward replacement:
- Your system is over 12 years old and the compressor is failing. A compressor replacement on an aging unit often costs 40 – 60% of a full system. In neighborhoods like Victoria Park and Rio Vista, where many homes still run original mid-2000s units, we frequently recommend replacement over a compressor swap because the remaining parts simply don’t justify the spend.
- You’ve had two or more major repairs in the last 18 months. Once a system starts needing capacitor replacements, fan motor work, and refrigerant recharges (topping off the cooling fluid your AC needs to run) in quick succession, it’s telling you something. The Kingswell Way says be honest with homeowners about that.
- Your energy bills have climbed without a change in usage. Fort Lauderdale’s humidity forces older, low-SEER systems to run longer and harder. A jump from a 10 SEER to a 16 SEER unit can meaningfully reduce monthly cooling costs, especially in older homes without updated insulation.
- Your system uses R-22 refrigerant. R-22 (Freon) production was phased out years ago, and the remaining supply is expensive. If your system leaks R-22, the recharge cost alone might be $200 – $400 per pound, and some units hold 6 – 10 pounds. Replacement with a modern R-410A or R-32 system often pays for itself within a few summers.
- The indoor coil or evaporator has failed and the unit is outside its warranty. A failed evaporator coil in an older system, especially in coastal-adjacent areas like Lauderdale Harbours or Coral Ridge, often signals corrosion throughout. Salt air accelerates metal fatigue, and patching one failed part frequently reveals another within months.
- Your home never cools evenly, no matter how many times the system is serviced. Undersized ductwork or an undersized condenser can’t be fixed by tuning up what’s there. In homes along Las Olas or in Sailboat Bend where additions have been built over the years, replacement with a properly sized system is often the only real fix.
Our AC Replacement Process
Replacing an AC system is a significant decision, so we don’t rush it. Here’s exactly how the job goes when you work with Cold Harbour Heating and Air Fort Lauderdale:
- Call and talk to a live person. When you dial (754) 354-7289, a real human answers, any hour of the day or night, every day of the year. No phone trees, no “leave a message and we’ll get back to you.” We schedule a firm arrival window and our technician shows up inside it.
- Load calculation and system assessment. Our technician measures your home’s square footage, checks window count and orientation, inspects the existing ductwork, and reviews insulation levels. We don’t guess at sizing. A system that’s too big short-cycles and leaves the air clammy in Fort Lauderdale’s humidity. A system that’s too small never catches up in August.
- Written proposal with a written price. Before any tool comes out of the truck, you get a written estimate covering the full scope: equipment, labor, refrigerant, electrical work if needed, and the removal of your old system. That price does not change at the door. This isn’t a policy we apply case by case. It’s one of the five values of The Kingswell Way: say the price before the work.
- Professional installation by a background-checked, uniformed technician. The person who walks through your door has been background-checked and wears a Cold Harbour uniform. You’ll know exactly who is in your home. Installation usually takes one day, sometimes two for complex ductwork modifications or multi-zone systems.
- Job site cleaned and system walked through. We leave the space cleaner than we found it. Then we walk you through the new thermostat, show you how to change the filter, and explain what regular maintenance looks like going forward.
- Written guarantee before we leave. Your replacement comes with a written warranty on the equipment and a written guarantee on the installation workmanship. The Kingswell Way requires it in writing, not verbal, not conditional, on paper. If something isn’t right inside the coverage period, we come back and make it right at no charge.
AC Replacement Pricing in Fort Lauderdale
What you pay for an AC replacement in Fort Lauderdale depends on three things: the size of your home, the efficiency rating you select, and whether your existing ductwork needs modification. Here are realistic ranges based on what we typically quote in the Fort Lauderdale market:
| System Type | Typical Installed Cost Range |
|---|---|
| 3-ton, 14 SEER single-stage, smaller condo or townhome | $5,800 – $7,200 |
| 4-ton, 16 SEER single-stage, 3 – 4 bedroom single-family home | $7,500 – $9,400 |
| 5-ton, 17 – 18 SEER two-stage, larger single-family home | $9,800 – $12,400 |
| Variable-speed inverter system, 18 – 20+ SEER, premium comfort | $11,500 – $15,000+ |
These ranges include equipment, labor, Refrigerant Recharge, basic electrical disconnect work, and removal of the old system. Ductwork modifications, new line sets through finished walls, or upgraded filtration systems add to the total. We’ll give you a written price before any work starts, so there are no surprises when the invoice arrives.
One note about Fort Lauderdale specifically: homes within a few miles of the ocean, particularly in areas like Harbor Beach or Idlewyld, experience accelerated corrosion on outdoor condenser coils. If you’re within salt-spray range, we may recommend a coastal-coated condenser, which typically adds $300 – $600 to the equipment cost. It’s not an upsell. It’s the difference between a condenser that lasts 8 – 12 years and one that rusts through in 5.
FAQs – AC Replacement
How much does it cost to replace an AC unit in Fort Lauderdale?
A full AC replacement in Fort Lauderdale typically costs between $5,800 and $12,400 installed, with most mid-size single-family homes landing in the $7,500 – $9,400 range for a 4-ton, 16 SEER system. Coastal homes may need a corrosion-resistant condenser, which adds a few hundred dollars. Call (754) 354-7289 for a free written estimate specific to your home.
How long does AC replacement take?
Most standard AC replacements in Fort Lauderdale are completed in one day, usually 6 – 8 hours from arrival to final walkthrough. Jobs requiring ductwork modifications, new line sets through finished walls, or multi-zone configurations can take two days, and we’ll tell you the expected timeline in your written proposal before work begins.
Is it cheaper to repair or replace my AC?
As a rule of thumb, if the repair cost multiplied by the age of the unit exceeds the cost of a new system, replacement is the better financial decision. In Fort Lauderdale, where systems run nearly year-round, a 12-year-old system that needs Compressor Repair costing $2,500 is usually better off retired than patched. We’ll give you an honest recommendation either way, with the numbers in writing.
Can you replace my AC the same day I call?
We keep common system sizes in stock and can often schedule installation within 24 – 48 hours. Same-day replacement isn’t always possible when a home needs a specific size or efficiency rating, but we’ll give you a firm installation date when you schedule. If your AC is completely down and you’re in a Fort Lauderdale heat wave, call (754) 354-7289 and we’ll get a technician out to at least assess the situation the same day.
Do you service my existing brand of AC?
Yes. Our technicians are trained to service and replace York, Daikin, Bryant, American Standard, Carrier, Trane, Lennox, Goodman, Rheem, and more. We don’t push one brand over another. We’ll recommend the system that fits your home’s size, your budget, and how long you plan to stay in the house.
If you’re tired of sweating through another Fort Lauderdale summer or throwing money at a system that’s already told you it’s done, call Cold Harbour Heating and Air Fort Lauderdale at (754) 354-7289. You’ll get a live person, a firm arrival window, and a written price before any work begins. The Kingswell Way in writing: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails.
