AC Installation in Boca Raton: Sized, Permitted and Started Up Right

A new AC installation in Boca Raton is judged on three things more than the brand on the cabinet: whether it was sized to the house, whether it was permitted and anchored to Florida code, and whether it was charged and started up to the manufacturer's numbers. This page covers all three, with the rules, the brands we install and the questions to ask any installer.

Replacing an Aging AC in a Boca Raton Home? What a Good Installation Includes

If your system is past ten years, the repair bills keep coming, and the quotes on your kitchen counter disagree on size, brand and price, you are not alone, and the disagreement is the useful part. ENERGY STAR suggests considering replacement when an air conditioner is more than 10 years old, needs frequent repairs, or leaves some rooms too hot or too humid. It also says ENERGY STAR certified equipment, installed correctly, can save up to 20 percent on heating and cooling costs. The words that matter there are installed correctly.

A good installation quote in Palm Beach or Broward County answers six things in writing: the capacity and how it was calculated, the indoor and outdoor model numbers as a matched system, the SEER2 rating, the refrigerant, what happens to the ductwork, drain and electrical, and who pulls the permit. If a quote cannot answer those, it is a price, not a plan.

Direct Cooling installs American Standard systems as a Customer Care Dealer and Rheem systems as a Pro Partner, under Florida certified air conditioning contractor license CAC1819111. Founder Frank Rey trains every technician to diagnose first and sell second, which on an installation means telling you when a repair still makes more sense. If you are still deciding, start with our repair or replace guide.

Sizing

Why AC Sizing Matters More in Florida Than the Brand

The short answer: an air conditioner has two jobs in South Florida, cooling the air and pulling water out of it, and an oversized unit does the first so fast that it skips the second. American Standard explains that an oversized system cools the home very quickly without properly lowering humidity and short cycles, and that the installer likely did not perform a Manual J load calculation. ENERGY STAR describes Manual J as the calculation of how much heating and cooling a home requires, and says your contractor should verify size with it.

The humidity load here is real. NOAA's 1991-2020 normals for West Palm Beach put the summer dew point at roughly 72 to 74°F from June through September. A system that runs in short bursts never gets the coil cold for long enough to drain that moisture, which is how a house ends up 74 degrees and clammy.

Florida's energy code is specific for new homes. Section R403.7.1 of the 2023 Florida Building Code, Energy Conservation, requires equipment to be selected with ACCA Manual S from loads calculated with ACCA Manual J or another approved method, bans designer safety factors, and caps cooling-only equipment at 1.15 times the calculated total load (or the closest available size), with latent capacity at least equal to the latent load. The code's section on alterations to existing homes (R503.1.2) points to other parts of Chapter 4 and does not list that sizing section, so never assume a replacement quote includes a load calculation. Ask for it.

Copying the old unit's tonnage is the shortcut to watch for. Homes change: windows get replaced, attics get insulated, rooms get enclosed. The tonnage that made sense in 1988 may not fit the house today.

The rules

SEER2 Minimums and Refrigerants for a New AC in Florida

Florida is in the Department of Energy's southeast region, where minimum efficiency is enforced by installation date. Refrigerant rules changed again in 2025 and 2026.

Minimum efficiency and refrigerant facts for residential split systems installed in Florida
ItemRequirement or valueWhat it means for your install
Split AC under 45,000 Btu/h (most homes)14.3 SEER2 minimum since January 1, 2023 (DOE)The legal floor. Higher SEER2 lowers summer bills.
Split AC 45,000 Btu/h and up13.8 SEER2 minimum (DOE)Applies to the largest residential systems.
Split heat pump14.3 SEER2 and 7.5 HSPF2 (DOE)Heating efficiency is rated separately; see our heat pump page.
Refrigerant GWP cap for new residential split systems700 (EPA Technology Transitions)R-410A, at a GWP of 2,088, cannot be used in newly manufactured systems.
R-454BGWP 465, A2L (EPA)Used by American Standard and Rheem in their current residential lines.
R-32GWP 675, A2L (EPA)Used in some ductless mini splits.
Leftover R-410A equipmentInstallable until supply runs out (EPA final rule, May 2026)EPA removed the January 1, 2026 installation deadline for pre-2025 R-410A split equipment.

A2L means lower toxicity and lower flammability under EPA's SNAP program. Existing R-410A systems can keep running and be repaired; EPA says the rules do not limit use or repair of installed equipment.

Brands

American Standard or Rheem: How the Two Lines We Install Compare

We are an authorized dealer for both brands, so the comparison starts from your house and budget.

  • American Standard Customer Care DealerAmerican Standard describes Customer Care Dealers as independent, hand-picked dealers, a program it has run since 1998.
  • American Standard tiersPlatinum 20 reaches up to 23.6 SEER2, Gold 17 up to 17.1 SEER2 and Silver 14 up to 14.3 SEER2, per American Standard's own comparison.
  • American Standard coveragePublished terms: a 10-year registered parts warranty against a 5-year base term, and up to 12 years on the compressor for select units.
  • Rheem Pro PartnerRheem's 2025 program requires at least 60 percent Rheem purchases, a 4-star rating from 30 or more reviews a year, 10 or more hours of training a year, and licensing, with re-evaluation every year.
  • Rheem Endeavor lineFour tiers (Prestige, Classic Plus, Classic and Select), with up to 10-year parts coverage and a 10-year conditional unit replacement.
  • Refrigerant on bothBoth brands' current residential systems use R-454B. American Standard pairs it with a factory refrigerant detection system on the coil.

Florida code

Permits, Wind and Flood Rules for a New AC in Palm Beach and Broward

A replacement AC is permitted work in every city we serve. The details differ by jurisdiction, and they are part of the job, not an extra.

A permit is required

Florida Statute 553.79 requires a permit to alter or repair a building system. Palm Beach County exempts repairs that do not alter the system listing, but a full change-out needs one.

Notice of Commencement

Palm Beach County requires a recorded Notice of Commencement for jobs valued at $15,000 or more.

Tie-downs for wind

Florida Mechanical Code 301.15 requires outdoor equipment to resist wind loads; Palm Beach County's building board says units on rated stands or slabs comply but must be adequately anchored.

Flood elevation

In flood zones, Florida Mechanical Code 301.16 requires equipment at or above the required flood elevation.

Broward is HVHZ, Palm Beach is not

The High-Velocity Hurricane Zone covers Broward and Miami-Dade. Coral Springs' 2026 change-out checklist asks for the AHRI certificate, tie-down details and electronic submission.

City rules vary

Delray Beach issues express A/C change-out permits within three days. Boynton Beach's change-out form bars increasing wire or equipment size and requires a disconnect within sight of the unit.

Installation day

AC Installation Day, Step by Step

What happens between the old unit coming out and the new one cooling the house.

Permit and protection

The permit is in the contractor's name and on site. Floors and paths to the air handler are covered.

Recover and remove

Refrigerant in the old system is recovered, not vented; EPA requires Section 608 certification to handle it. Old equipment leaves with us.

Set and anchor

The condenser goes on a level stand or pad and is anchored for wind load; the air handler or coil is set with a trapped drain and an overflow switch.

Connect and evacuate

Line set connected or replaced as the new refrigerant requires, then the system is pulled into a deep vacuum to remove air and moisture.

Charge to spec

Charged to the manufacturer's specification. ENERGY STAR notes too much or too little refrigerant lowers efficiency and shortens equipment life.

Start up and walk through

Temperatures, pressures and airflow measured at startup (ENERGY STAR: airflow problems can cut efficiency up to 15 percent), then thermostat, filter and warranty explained.

Ducts, drains and electrical

What We Check Before Quoting a New System

The short answer: the outdoor unit is the visible part, but the ductwork, condensate drain and electrical circuit decide how well it performs. Those get inspected before a price is given, so the quote does not change after the old unit is out.

Ductwork first. ENERGY STAR estimates that 20 to 30 percent of the air moving through a typical duct system is lost to leaks, holes and poor connections. In Florida attics it is worse: Florida Solar Energy Center research found that a 15 percent return leak drawing from a hot attic can cut cooling capacity and efficiency by roughly half. A new high-SEER2 condenser feeding leaky ducts cannot deliver its rating. If ducts need sealing or repair, it is quoted as its own line; see ductwork.

Drains next. In our humid climate the condensate system is where most water damage starts, so a new installation gets a properly trapped drain and an overflow switch; Trane notes these switches shut the system down before a clogged drain overflows. Then electrical: the disconnect, breaker and wire size have to match the new unit's requirements, and some cities treat a new disconnect or stand change as its own sub-permit.

Age matters here too. Census ACS figures put the median year built for homes in west Boca ZIP codes between 1983 (33434) and 1991 (33496, 33498). Many of those homes still have original duct runs and air handler closets that were sized around equipment from that era.

Before you sign

Questions to Ask Any AC Installer in Boca Raton

Use these with every quote, ours included.

  • Is your license active? Look it up at myfloridalicense.com. Ours is CAC1819111, a Florida certified air conditioning contractor license active through August 31, 2028.
  • Did you run a Manual J load calculation for this house, and can I see the result?
  • What are the exact indoor and outdoor model numbers, and are they rated as a matched system?
  • What SEER2 rating and refrigerant does each option use?
  • Will the permit be pulled in your company's name, and who schedules the final inspection?
  • What did you find in the ductwork, drain and electrical, and is any of that priced separately?
  • Does this system qualify for FPL's AC rebate? FPL requires a qualifying high-efficiency system installed by a participating contractor, so ask whether your installer participates.
  • Do not plan around a federal tax credit: ENERGY STAR lists the residential credit as available only through December 31, 2025.
Warranty

How Florida Law Protects Your New AC Warranty

The short answer: in Florida, when a licensed contractor installs your equipment, the manufacturer's warranty runs its full term from the installation date, and it is not conditioned on registering the product. That comes from Florida Statute 559.957, which applies to HVAC equipment installed by a contractor licensed under Chapter 489.

This matters because manufacturers' national terms often tie the longer coverage to online registration within a set window. Florida law overrides that condition for licensed installations. We still register the equipment with the manufacturer, because it puts the serial number and install date on record and speeds up any future claim.

Selling the house? Florida Statute 559.956 provides that the warranty transfers automatically to the new owner when the home is sold, without a transfer fee, for sales on or after July 1, 2024. Keep the installation paperwork and the permit number with your home records; a buyer's inspector will ask for both.

Local record

Our Installations on the Palm Beach County Permit Record

Anyone can say they install in Boca Raton. Permit records show it. Palm Beach County's permit system lists 24 permits under license CAC1819111 in unincorporated Palm Beach County from 2018 through 2026, including seven exact like-for-like residential A/C change-outs, ten general mechanical permits and a new ductless mini split in 2026.

Seventeen of those permits are in unincorporated west Boca, the area around our Boca Commerce Park office, across ZIP codes 33428, 33433, 33434, 33496 and 33498. Change-outs on that record include homes in Boca Chase, Mission Bay, Mizner Pointe of Boca, Boca Landings North and a Charter Cay condominium in Boca West. The mini split went into a new home in Johns West. The City of West Palm Beach's records add a 2022 change-out to a Rheem 2.5-ton system.

City permits inside Boca Raton, Delray Beach and Boynton Beach are filed in each city's own system, so they are not part of the county count. If you want to see how we work in your neighborhood, our west Boca Raton page maps the communities, and the full list of cities is on the service area page.

Building or remodeling?

New construction and remodel installations follow the full Florida energy code sizing requirements (Manual J and Manual S). Builders and general contractors can schedule directly with our team around the build timeline. For homes where ducts are impractical, ask about ductless mini splits.

FAQ

AC Installation Questions

Direct CoolingFL Certified AC Contractor CAC1819111 Dispatch 24/7

Hi, this is Direct Cooling. Tap a question below for a straight answer.

Tap a question to ask

How long does AC installation take?
It depends on scope more than on the equipment. A straight swap of a matched outdoor unit and air handler in the same locations is the shortest job. Adding a new stand, replacing the line set, moving the air handler, sealing or replacing ducts, or upgrading the electrical all add time, and some need extra inspections. We confirm the schedule in writing with the estimate.
Can I install an air conditioner myself in Florida?
Palm Beach County does allow owner-builder permits, limited to a residence or building for your own use. Handling refrigerant requires EPA Section 608 certification, so connecting and charging a split system is not a homeowner task. Florida's warranty protection in Statute 559.957 also applies specifically to equipment installed by a licensed Chapter 489 contractor.
Is a bigger AC better for Florida humidity?
No. An oversized system cools the air quickly and shuts off before it removes moisture, which leaves the house cool but clammy and causes short cycling, as American Standard and Carrier both explain. Florida's energy code for new homes caps cooling-only equipment at 1.15 times the calculated load for that reason. The right size comes from a Manual J calculation, not from the old unit's label.
Can I still get an R-410A system installed?
Possibly, while stock lasts. EPA's May 2026 final rule removed the January 1, 2026 installation deadline for R-410A split equipment manufactured before 2025, so remaining inventory can be installed until supply runs out. New production uses A2L refrigerants such as R-454B. We will show you both options and how refrigerant supply might affect future service.
Do I have to register my AC warranty in Florida?
Under Florida Statute 559.957, when a licensed contractor installs the equipment, the manufacturer warranty runs its full term from installation and is not conditioned on registration. We still register it for you, because a registered serial number makes any future claim faster.
Which AC brands do you install?
Direct Cooling is an American Standard Customer Care Dealer and a Rheem Pro Partner, so we install both and quote them side by side with SEER2 ratings and refrigerant type. If you are leaning toward one brand, our American Standard and Rheem pages cover each line in more depth.
