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. Replacing an air conditioner is not urgent until it is. Most homeowners plan the installation around a season rather than a breakdown, and that is the cheaper way to do it.
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. Air conditioning equipment ages faster on the coast than the brochure suggests. Fifteen years of salt air is closer to twenty inland, and installation costs have not risen as fast as repair bills. Heating barely factors into equipment life here.
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. An older air conditioner running R-22 is worth replacing rather than feeding. New air conditioning equipment uses current refrigerant and stays serviceable.
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. Age matters as much as the bill. A fifteen-year-old unit rarely earns a fourth repair, and the air conditioning installation figure sits on the same page so you can weigh it.
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. A modern air conditioner holds temperature with far less runtime. Heat pumps do the same job and cover heating too, which matters on the handful of cold nights we get.
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. Uneven rooms usually trace back to sizing rather than the air conditioner itself. A correct installation fixes the balance without extra equipment.
We handle the whole job, from sizing to permit, so the system runs efficiently from the first day. That covers the whole air conditioning installation, from the first measurement to the final inspection. Nothing gets subcontracted out.
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. Right-sizing is what separates a good air conditioning installation from a cheap one. An oversized unit costs more to run and cools worse.
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 fit air conditioning equipment from the main manufacturers rather than one house brand, so the installation suits the home instead of the stock list. Heat pump options cover heating for the few weeks it matters.
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. The old air conditioner leaves with us the same day. Nothing sits in the yard waiting on a second trip.
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. Commissioning is where a good air conditioning installation is proven. We measure the air coming off the coil rather than assuming the equipment left the factory correct.
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. The permit is part of the installation price, not an extra. Heat pump work follows the same route.
Our Process
We come out, measure the home, and size the system. You get a written quote with the system options and the price. The visit takes about an hour. You get the air conditioning options in writing, with the installation cost broken out.
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. Efficiency ratings matter more here than most places, because the air conditioner runs most of the year and heating hours are few enough to be an afterthought.
The crew removes the old system, sets and connects the new equipment, and installs to code. A straightforward swap takes most of a day. Larger jobs with new ductwork get scheduled across two days so nobody sleeps without cooling, and the air conditioning installation is tested before the crew leaves.
We charge it to spec, test airflow and temperature, and walk you through the new thermostat and the warranty before leaving. The walkthrough covers the thermostat, the filter schedule, and what to expect from the new air conditioner in its first week.
AC installation is part of what Frostline does as an AC specialist. The technicians install and service residential AC and HVAC systems every day. Air conditioning is the whole trade here, not a sideline to plumbing or roofing. That focus is why an installation gets finished in a 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, and the work is backed by a warranty. Heat pumps are available where a homeowner wants heating and cooling from one unit, and the installation takes no longer.
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. Coastal air is hard on equipment. An air conditioner here works nine months solid, so installation quality shows up sooner than it would up north.

Answers to the questions homeowners ask most before installing or replacing an AC. These come up on most air conditioning installation calls.
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. Those ranges cover the air conditioner, the installation labor, and the permit. Ductwork is the item that moves the number most.
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. A heat pump installation runs about the same. Anything involving ductwork adds a day.
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. Sizing is measured, never estimated. An air conditioning unit chosen from square footage alone is usually wrong for a coastal home.
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. Refrigerant choice is settled at installation and rarely revisited, so it is worth getting right on the air conditioner you keep for fifteen years. Heating performance is unchanged either way.
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. Age decides most of it. An air conditioner past fifteen is usually an installation conversation rather than a fix.
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. Air conditioning installation is licensed work for good reason. Refrigerant handling alone puts it out of reach for most homeowners.
