AC Replacement
AC Replacement — How to Know You Actually Need One
The repair-or-replace decision, made with numbers instead of pressure. If the system is worth fixing we will tell you so.
This page is about the decision, not just the equipment. Most homeowners do not want a new air conditioner — they want to stop paying for the old one. So the first thing we do on a replacement call is establish whether replacement is genuinely the right answer, and the honest answer is often no. A fourteen-year-old system with a failed capacitor is a repair. A nine-year-old system with a leaking evaporator coil is a real decision. A system on R-22 with a dead compressor is not a decision at all.
The numbers we work from are the age of the equipment, the cost of the repair in front of us, the refrigerant it runs on, how many times it has already been repaired, and what it is costing to run compared with what a current system would cost. When those point at replacement we say so and show the working. When they do not, we fix it and leave. Our first quote is our last quote either way, so there is no commercial reason for us to steer you.
If replacement is the right call, sizing is where the job is won or lost. Florida is the worst place in the country to oversize a system: a unit with more capacity than the house needs satisfies the thermostat quickly, shuts off before it has removed any moisture, and leaves you with a house that is cold and clammy. We calculate the load rather than matching the tonnage of whatever was there before, because what was there before was frequently wrong too.
When replacement is usually the right answer
- The compressor has failed and the system is out of warranty
- The system still runs on R-22, which is no longer produced and is expensive to top up
- A leaking evaporator coil on a system past ten years old
- Repairs in three consecutive seasons on the same unit
- Electricity bills climbing year on year with no change in how you use the house
- The house cools but never dries out — a classic sign the existing unit was oversized
What a replacement job includes
- A load calculation for the actual house, not a tonnage match to the old unit
- A written quote covering equipment, labour, permit and disposal — no line items appearing later
- Matched indoor and outdoor equipment so the rated efficiency is the efficiency you get
- Line-set evaluation, flush or replacement — a new condenser fed by a contaminated line set fails early
- New filter drier, correct refrigerant weight, and a verified charge rather than a topped-up guess
- Commissioning readings — temperature split, static pressure and superheat/subcooling — recorded on completion

How do I know you are not just selling me a system?
Because we quote the repair first. If the repair is the sensible answer we do it — that is a smaller invoice and we still do it. When we do recommend replacement, ask us to show you the numbers behind it: age, refrigerant, repair cost and running cost. If those do not justify it, do not buy it.
Is a bigger unit better in Florida?
No, and it is the most common mistake in Florida installations. An oversized system reaches the thermostat setting fast and then stops, which means short run times and very little moisture removed. The result is a house that feels cold and damp at the same time. Correct sizing runs longer, cheaper and drier.
Do you handle the permit?
Yes. Air conditioning changeouts require a permit and inspection in Florida jurisdictions, and the permit is part of our quote rather than a surprise afterwards.
How long does a changeout take?
A straightforward residential changeout is usually a single day. Jobs that also involve duct modifications, an electrical change or difficult access — high-rise units in particular — can run into a second day, and we will tell you that before we start rather than at 5 PM.
