Repair or Replace Your Air Conditioner
Repair a young system with a single failed part. Replace when the compressor goes, when the refrigerant is R-22, when repairs are stacking up, or when the unit is past its expected life in Florida heat.

Repair a young system with one failed part and a sound rest. Replace when the compressor fails, when the system still runs R-22, when repairs are stacking up, or when the unit is past its expected service life in Florida heat.
Almost every homeowner is asked this question at the worst possible moment: it is August, the house is 84 degrees, and someone is standing in the yard with a number. That pressure produces bad decisions in both directions.
The useful frame is not the cost of this one repair. It is whether you are buying years or buying weeks, and whether the money is going into a system with a future.
01
Repair or replace
Repair usually makes sense when
- The system is comfortably inside its expected life
- One identifiable part failed, such as a capacitor, contactor or blower motor
- The refrigerant is current, not R-22
- The coils and the ductwork are in good condition
- This is the first real repair on the system
- The repair costs a small fraction of a replacement
Replacement usually makes sense when
- The compressor has failed
- There is a refrigerant leak in the evaporator or condenser coil
- The system runs R-22, which is no longer produced
- This is the third service call in two seasons
- The system never controlled humidity properly to begin with
- The repair approaches a meaningful share of a new system
02
The repairs that change the answer
Compressor failure
The single most expensive component in the system. On an older unit, replacing it is usually putting the most costly part into a machine whose other parts are the same age.
Coil leaks
A leaking evaporator or condenser coil is a major repair, and on an aging system it often signals that the rest of the sealed system is nearing the same point.
R-22 systems
R-22 has not been produced or imported in the United States since 2020. Recovered and reclaimed supply still exists, but it is limited and it is expensive, and every recharge on a leaking R-22 system is money spent on a dead end.
Repeated capacitor failures
A capacitor is a cheap part. Replacing it three times in two years usually means something else, often the compressor drawing hard, is killing it.
Frozen coils that keep returning
Usually airflow or refrigerant charge. If it has been diagnosed twice and it is still happening, the diagnosis was not the whole story.
Water where it should not be
A rusted-through drain pan or a corroded air handler base is a condition problem, not a part problem, and it is a sign of how the unit has been living.
03
Questions to ask before you agree to anything
- What exactly failed, and what caused it to fail
- What refrigerant does this system use
- How old is the system, from the data plate, not from an estimate
- If I do this repair, what is the next most likely failure
- What is the warranty on the repair itself
- If I replaced instead, what would the system look like and what would it cost
- Can I have both options in writing before I decide
Any technician who will not put both options in writing, or who needs an answer today, is selling rather than diagnosing.
04
If it is 95 degrees and you have to decide now
A temporary repair to get the house cool is a legitimate move, and it does not commit you to anything. Getting a system running for the week so you can make the bigger decision calmly is usually cheaper than making the bigger decision badly.
What is worth avoiding is a large repair signed under heat pressure. If the number is significant, it is worth the hours it takes to get a second opinion, even in August.
Questions we get on this
- Should I repair or replace my air conditioner?
- Repair a young system with one failed part and sound coils and ductwork. Replace when the compressor fails, when a coil leaks, when the system uses R-22, or when repairs have become a pattern rather than an event.
- My AC uses R-22. Does that mean I have to replace it?
- Not immediately, but it changes the math. R-22 has not been produced or imported in the United States since 2020, so supply comes from recovered and reclaimed stock, which is limited and expensive. Repeated recharges on a leaking R-22 system are money with no future in it.
- How much should an AC repair cost before I stop repairing?
- There is no universal number, and the common rules of thumb are crude. The better question is what you are buying: a repair that gives a sound system several more years is different from a repair that gives a worn system one more summer.
- Is it worth replacing a compressor?
- On a system still under parts warranty and otherwise in good condition, often yes. On an older system out of warranty, you are installing the most expensive component into a machine whose remaining parts are the same age as the one that just failed.
- My AC runs constantly. Is that bad?
- Not necessarily. In Florida a properly sized system running long cycles is what removes humidity. Constant running paired with a house that will not reach setpoint is the problem, and that usually points to charge, airflow, or a system that is undersized for the load.
- Can I get a second opinion without paying twice?
- Most companies charge a diagnostic fee, and on a large repair it is generally worth paying it. The cost of one extra diagnostic is small next to the cost of replacing a system that did not need replacing, or repairing one that did.
