How Long Does It Take to Install a New AC Unit in Palm Beach County?

Date & Time
Ask three contractors how long a new AC takes and you will hear the same answer: one day. They are right about the day the crew shows up. They skip the weeks around it.
Here is the straight answer. Installation day runs about 4 to 8 hours for a standard replacement, according to Trane's installation timeline guide. The full project, from the first call to the final inspection, runs a few days up to two weeks. In Palm Beach County, permits, inspections, and HOA approvals set that calendar more than the crew does.
The Short Answer: Install Day Versus the Whole Project
Two clocks run on every AC replacement. The first is the install day. The second is everything that has to happen before the crew can start and after they finish.
Trane breaks the full process into research, quotes, choosing an installer, scheduling, and then the 4 to 8 hour install itself. It also notes that quotes take longer to get in midsummer. In South Florida, midsummer is also when most systems fail, so the whole county competes for the same crews.
The table below shows how our projects typically run in Palm Beach County.
Stage | Typical time | What drives it |
|---|---|---|
Home assessment and written quote | One visit, often same day | Your schedule and access to the attic and outdoor unit |
Permit and HOA or condo approval | Several days up to a few weeks | Your city, your board, and how fast paperwork returns |
Equipment ordering | Same day to several days | Brand, size, and what is on the shelf |
Installation day, equipment only | 4 to 8 hours | Access, electrical, and condition of the old system |
Installation with ductwork changes | One to two days | Amount of duct replaced and attic conditions |
Final inspection | Scheduled with your city | Local inspector availability |
What Happens During Those 4 to 8 Hours
A standard changeout follows the same order every time. Knowing it helps you judge a crew that rushes or drags.
The crew protects your floors and walls, then shuts off power to the system.
Technicians recover the old refrigerant into a tank and remove the outdoor condenser and the indoor air handler or furnace.
They set the new condenser on a level pad and mount the new indoor unit.
They connect the refrigerant line set, the electrical supply, and the condensate drain.
They pull a vacuum on the lines, release the refrigerant charge, and check pressures and airflow.
They run the system through a full cooling cycle, review it with you, and haul the old equipment away.
You lose cooling for the whole visit. In July, that matters. Ask the crew for a start time and a narrow arrival window, and plan to spend the afternoon out of the house or near a fan.
What Adds Days to an Installation
Four things stretch a one-day job.
Ductwork. Trane notes that leaky ducts should be sealed or replaced to protect efficiency, and that adds time. Replacing a section of attic duct often adds a second day.
Electrical mismatches. Palm Beach County's AC change-out form asks for the minimum circuit ampacity, the breaker or fuse size, and the wire size for both the old and new systems. If the new system needs a different breaker or wire, an electrician work step enters the schedule.
Access. A tight attic, a second-story air handler, or a condo unit that needs a crane or a roof lift slows every step.
Mismatched parts. The same form asks for the evaporator coil model number when an air handler accepts more than one coil. A new condenser paired with an old coil is a common source of day-of surprises. Replace the matched set and the job stays predictable.
The Part Nobody Quotes: Permits and Inspections
An AC replacement in Palm Beach County needs a permit. The paperwork asks for details of both systems: manufacturer, model numbers, tonnage, voltage, SEER2 or EER2 rating, and circuit and breaker sizes. The installing contractor signs a certification that the information matches what the crew installs.
Each city runs its own process. West Palm Beach publishes an A/C change-out compliance form that the field inspector must see at the time of inspection. The Town of Jupiter's residential air conditioning checklist sets up an equipment-only change-out permit and requires a Manual J load calculation only when the contractor resizes the system. Change the ductwork and you work through the building department for additional requirements.
Your contractor pulls the permit and schedules the inspection. You should still ask three questions before you sign: Who pulls the permit, when does it go in, and who meets the inspector?
HOA and Condo Approval Add Their Own Clock
If your home sits in an HOA or condo community, your board often wants to approve the equipment and the condenser location before work starts. Boards meet on their own schedules, so start that request the day you sign. We cover what boards can and cannot control in our guide to HOA rules for AC replacement in Palm Beach County.
Why a Faster Install Is Not a Better Install
A crew that finishes in three hours sounds efficient. It also sounds like a crew that skipped steps.
The ENERGY STAR quality installation fact sheet lists four installation requirements: proper sizing and component matching, sealed ducts, the correct refrigerant charge, and adequate airflow. It shows that a typical air conditioner delivers about 73 percent of its rated energy, with the rest lost to duct leakage (about 15 percent), improper sizing (about 5 percent), improper refrigerant level (about 4 percent), and improper airflow (about 3 percent). The same fact sheet estimates that improved installations save 18 to 36 percent on air conditioners and heat pumps.
Every one of those losses happens on install day. Sizing happens before it, which is why we point homeowners to our Florida AC sizing guide. A system that is too big short cycles and leaves the house humid. A system that is too small runs all afternoon.
Salt air adds another reason to go slowly. Coastal homes within a mile or two of the water wear out coils faster, as we explain in our post on how long AC units last in coastal Florida. Coastal-grade equipment and a careful coil match belong in the plan, not in a rushed afternoon.
How to Cut Your Wait Without Cutting Corners
Decide before the system dies. A planned replacement gives you time to compare quotes and clear permits. An emergency replacement compresses all of it into a hot weekend.
Verify the license first. Florida's MyFloridaLicense public records lets you look up a contractor by name or license number in minutes.
Send HOA paperwork early. Ask your contractor for the equipment specs on day one.
Clear access. Move storage away from the air handler and the outdoor pad the night before.
Get the price in writing. A written, upfront price removes day-of surprises. Our guide to AC scams in Palm Beach County shows what bait-and-switch quotes look like.

Frequently Asked Questions
How long does it take to install a new AC unit?
Installation day takes about 4 to 8 hours for a standard replacement. The full project takes a few days to two weeks once you count quotes, permits, and approvals.
How long does it take to replace an AC unit with new ductwork?
Plan on one to two days. Ductwork changes add crew time and extra requirements from your building department.
Do I need a permit to replace my AC in Palm Beach County?
Yes. Your contractor files a change-out permit with the details of the old and new systems, and the inspector reviews the paperwork at inspection.
Will I have no AC during the installation?
Yes. The system stays off for the whole install visit. Ask your installer for a start time and a target finish time so you can plan the day.
How do I prepare for installation day?
Clear a path to the air handler and the outdoor pad, secure pets, move vehicles from the driveway, and confirm HOA or condo approval in writing.
