Repair or Replace Your AC? A Wellington, FL Homeowner’s Guide

This is the question every homeowner eventually faces, usually at the worst possible moment: the system is down, a technician is standing in your garage, and you have to decide whether to spend money fixing something old or spend considerably more replacing it.

Here is how to think it through clearly — including the math, the things people forget to factor in, and the honest answer about when repair is still the right call.

The rule most contractors use

Multiply your AC’s age in years by the repair cost. If the result is over 5,000, replacement is usually the better value.

A 12-year-old system with a $600 repair: 12 × 600 = 7,200. Lean toward replacement. A 6-year-old system with a $450 repair: 6 × 450 = 2,700. Repair it.

It is a rough guide, not gospel. But it is a reasonable starting point and it stops the decision being purely emotional.

A simpler version: if the repair costs more than a third of a new system, and the unit is past ten years old, replacement usually wins.

Why Florida changes the math

National guidance on AC lifespan assumes a system running a few months a year. Wellington homeowners do not live in that world.

Here, systems run close to year-round. Add constant humidity, which forces the equipment to work hard on moisture removal as well as temperature, and the result is simple: a system rated for 15 to 20 years commonly delivers 10 to 12 in South Florida.

So when a Wellington homeowner asks whether a 13-year-old unit is “too old to fix,” the honest answer is usually yes, that unit has already had a full working life here.

Repair makes more sense when…

• The system is under 10 years old
• It is still under warranty — many manufacturers cover parts for 10 years if the unit was registered at install
• The failed part is inexpensive: capacitor, contactor, thermostat, drain line, fan motor
• This is the first real problem the system has had
• Cooling and energy bills have otherwise been normal

A well-maintained 8-year-old system that needs a capacitor should get a capacitor. Anyone telling you otherwise is selling, not diagnosing.

Replacement makes more sense when…

• The system is past 12 years old
• The compressor has failed — this is the expensive one, and on an older unit it rarely justifies the spend
• It uses R-22 refrigerant. Production ceased in 2020, and recharging now costs enough that a single significant leak repair can approach replacement territory
• You have had multiple repairs in two years
• Electricity bills keep climbing with no change in habits
• Some rooms never get comfortable no matter what the thermostat says
• The house feels damp or sticky even while the AC runs — an oversized or failing system cools the air without removing enough moisture

That last one matters more here than most places. Our guide on why a house feels sticky with the AC running covers the humidity side in more detail.

The costs people forget

Efficiency. A 12-year-old unit at SEER 10 against a modern SEER 16 is a meaningful difference on a Wellington electric bill, every month, for the life of the system. Over ten years that gap often covers a large share of the replacement cost on its own.

Repeat repairs. Spending $700 now and another $900 next summer on a system you replace anyway two years later is $1,600 you did not need to spend.

Timing. Replacing on your own schedule in a cooler month means you compare quotes properly and choose your equipment. Replacing in an emergency in August means taking whatever is available at whatever it costs.

Humidity damage. A system that cannot keep up lets indoor humidity climb, which over time means musty smells, warped wood, and mold risk. That is a house problem, not just a comfort problem.

What a replacement involves

A proper replacement is not just swapping the box outside:

1. Load calculation. Your contractor should measure your home — square footage, insulation, window area, orientation — and size the system to it. Oversized units short-cycle, which means they cool fast and shut off before removing humidity. That is how you end up with a cold, clammy house.
2. Matched components. The outdoor condenser and indoor air handler should be a matched set. Mixing mismatched components costs you the efficiency rating you paid for.
3. Ductwork check. Leaky ducts can waste a large share of your cooled air before it reaches a room. Worth inspecting while everything is open.
4. Permit and inspection. Required in Palm Beach County. A contractor who suggests skipping it is not one to hire.
5. Registration. Register the unit with the manufacturer within the window or you may lose the extended parts warranty.

Most full replacements, including the air handler, can be completed in a single day.

Our honest position

We would rather fix your system than sell you a new one, and we will tell you when a repair is the better buy — including when that means a smaller invoice for us.

But we will also tell you plainly when a unit is finished, because stringing along a dying system through a Florida summer costs you more than replacing it did.
