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.
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.
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.
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.
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.
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.
We handle the whole job, from sizing to permit, so the system runs efficiently from the first day.
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.
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.
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.
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.
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.
Our Process
We come out, measure the home, and size the system. You get a written quote with the system options and the price.
We match the right size and efficiency to your home and budget. You see the equipment, the SEER2 rating, and the cost before anything is ordered.
The crew removes the old system, sets and connects the new equipment, and installs to code. A straightforward swap takes most of a day.
We charge it to spec, test airflow and temperature, and walk you through the new thermostat and the warranty before leaving.
AC installation is part of what Frostline does as an AC specialist. The technicians install and service residential AC and HVAC systems every day.
We install new high-efficiency systems that meet the new Florida SEER2 minimum, remove and dispose of the old unit, and pull the permit. Technicians are licensed, insured, and bonded, Frostline is BBB accredited, and the work is backed by a warranty.
Frostline installs and replaces AC systems across Delray Beach and coastal Palm Beach County, where systems run nine to ten months a year and salt air shortens their life. When repair stops making sense, we give you the numbers and the replacement options.

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