Signs It's Time to Replace Your AC

Replacing an AC is a big decision, and a few signs make it the smarter one. These are the most common reasons Florida homeowners replace a system instead of repairing it again.

An older outdoor AC condenser nearing the end of its service life

Your AC is 15 years or older

Most AC systems last 15 to 20 years in Florida, less if they've been neglected. Past the 15-year mark, parts get harder to find and efficiency drops, and a new system starts paying you back in lower bills.

It still runs on R-22 refrigerant

R-22 hasn't been made since 2020, and a recharge can run over $1,500. If an older R-22 system springs a leak, an emergency AC repair rarely pays off, and replacing it costs less than feeding it refrigerant year after year.

Repairs are adding up

One repair is normal. Two or three in a couple of seasons on an aging system is a pattern. When the repair bills start to rival the cost of a new unit, replacement is the better money, and Frostline shows you the numbers instead of pushing.

Energy bills keep climbing

An aging or undersized system runs longer for less cooling. Newer high-efficiency units meet the new Florida SEER2 minimum and cut the runtime, which shows up on the power bill month after month.

Some rooms never cool evenly

Hot bedrooms and a cold living room often mean the system was never sized right for the home. A Manual J load calculation and a properly sized new system fix the imbalance.

What's Included in a Frostline AC Installation

We handle the whole job, from sizing to permit, so the system runs efficiently from the first day.

Right-Sizing with a Manual J Load Calculation

An oversized AC short-cycles and never runs long enough to pull humidity, leaving the house cold and damp. We run a Manual J load calculation, based on your home's size, insulation, windows, and ductwork, so the new system is sized right.

Equipment & Refrigerant Selection

We install new high-efficiency systems that meet the new Florida SEER2 minimum, and we service all the major AC brands. New units run on the current R-454B refrigerant, since R-410A systems are no longer manufactured. We go over the options and the cost with you before you decide.

Old-Unit Removal & Disposal

We remove and haul away the old air handler and condenser, and recover the old refrigerant the way the EPA requires. The work area is left clean, with the new equipment on a level pad.

Installation & Commissioning

We set the equipment, connect the line set and electrical, pull a vacuum on the lines, charge it to spec, and test airflow and temperature before we leave. Keep up with regular AC maintenance and the warranty and efficiency both hold up.

Permit & Inspection

AC replacement in Florida needs a permit and an inspection. We pull the permit, install to code, and handle the inspection, so you have the paperwork and the warranty stays good.

Common AC Installation Questions

Answers to the questions homeowners ask most before installing or replacing an AC.

How much does a new AC unit cost in Florida?

Most full AC replacements in Florida run $3,500 to $12,000, and most jobs land around $7,000 to $10,000. The price depends on system size, efficiency rating, any ductwork or electrical work, and removing the old unit. Frostline gives you a written quote before any work starts.

How long does an AC installation take?

A straightforward swap takes most of a day, four to eight hours. Adding ductwork, electrical upgrades, or a new pad can stretch it to a full day or more. Frostline gives you a realistic timeline with the quote.

What size AC do I need?

The right size comes from a Manual J load calculation, not a rule of thumb. An oversized unit in Florida is actually worse: it short-cycles and never runs long enough to pull humidity, so the house feels cold and damp. Frostline measures the home and sizes the system to it.

Should I get an R-410A or R-454B system?

New systems use R-454B or R-32, since R-410A units stopped being manufactured at the start of 2025. The newer refrigerant cools just as well and is much easier on the environment. We install the current refrigerant, so your system stays easy to service for years.

Should I repair or replace my AC?

It depends on the age and the cost. A newer system with one failed part is usually a repair. An older system, an R-22 unit, or one stacking up repair bills is usually a replacement. Frostline's AC repair team gives you the repair-versus-replace numbers first.

Can I install my own AC in Florida?

Not really. AC installation needs a permit, an electrical hookup, and refrigerant handling — and under EPA rules that means a licensed tech. A DIY or unpermitted install also voids most manufacturer warranties. We handle the permit, the install, and the inspection, so it's all covered.
