AC Installation Process Step-by-Step

- AC Installation
Thinking about getting a new AC? Here’s the truth: installing one in Boca Raton isn’t as simple as swapping out a box. Between the humidity, salty air, and local building rules, there’s more to the job than most people realize.
We’ve been through hundreds of these installs here at PRIME AIR, and every one has a few quirks. Let’s walk through what really happens — step by step — so you know what to expect when the crew rolls up to your driveway.
Why Doing It Right the First Time Matters
We’ve seen it too often — someone rushes an install, skips a seal, forgets a drain angle, or doesn’t size the system right. It might cool okay for a few months, but the energy bills climb, the humidity creeps in, and the compressor starts complaining.
Boca’s weather is unforgiving. Salt eats metal, and humidity tests every gasket. That’s why the process matters. A precise installation gives you steady cooling, lower bills, and a system that lasts.
Step 1: The Home Visit
The first visit isn’t about paperwork — it’s about learning your home.
We walk through every room, look at how the air moves, note your insulation, attic space, and even how the sunlight hits in the afternoon. All of that feeds into what we call a load calculation — basically, figuring out how much cooling power your house actually needs.
Too big a system? It cools too fast and leaves the air sticky. Too small? It runs forever and never quite gets there. We find the sweet spot. Then we talk equipment — brands, efficiency ratings, corrosion-resistant options for the coast — and make sure it’ll fit your lifestyle (and your HOA’s rules).
Once you’re happy, we handle the permits. No guessing, no city hall headaches.
Step 2: Out With the Old, Prep for the New
This part gets a little messy, but it’s handled carefully. We recover refrigerant (legally — the EPA’s strict about that), disconnect the old system, and clear the space. The condenser pad gets leveled and checked for drainage, and sometimes, we raise it a few inches if your area tends to flood.
Before a single new part goes in, we check your ducts. A shiny new system won’t mean much if air is leaking into your attic. We seal, insulate, or reroute as needed, and prep wiring for what’s coming next.
Step 3: Installing the System
Here’s where the magic happens.
The outdoor unit gets set first — balanced, bolted, and secured for wind resistance (Boca storms aren’t shy). Inside, the air handler or evaporator goes in place, tied into ductwork and drainage.
Then we run refrigerant lines between the two. These copper lines are brazed together under nitrogen — that little step keeps the inside of the pipe clean so your system runs more efficiently. We also wrap and insulate them to keep condensation away from your drywall.
Electrical lines, disconnects, and thermostats — it all gets connected neatly, labeled, and tested.
Step 4: The First Breath — Testing and Charging
Before we ever add refrigerant, we pull a deep vacuum to remove air and moisture. Then we pressure test the system with nitrogen — if it holds, we charge it precisely according to specs.
The first startup is always a bit exciting. We check pressures, amperage, air temperature splits, and airflow in every main room. When it hums quietly and holds the right temps, we know it’s dialed in.
Step 5: Fine-Tuning and Handoff
Now comes the polish. We balance airflow so no room feels muggy or freezing. Dampers get adjusted, thermostats programmed, and smart controls synced if you have them.
Then we do a final walk-through together. You’ll see how to change filters, check your drain line, and manage settings. We register your warranty, clean the workspace, and make sure you’ve got all the paperwork handy.
Boca Raton Has Its Own Rules
Here, the air is salty, humid, and heavy — which means corrosion and moisture management are a big deal. We use coated coils, stainless fasteners, and rust-resistant supports.
We also make sure outdoor units are anchored against tropical winds and raised when needed. And yes, every job gets permitted, inspected, and documented. You’d be surprised how many DIY jobs get flagged later for not doing that.

Common Questions We Hear
How long does it take?
Usually, a day or two. Permits and inspections can add a little time.
Can I do it myself?
You could — but between refrigerant laws, electrical work, and warranty conditions, it’s not worth the risk.
What size AC do I need?
That’s what the load calculation is for. Bigger isn’t better here; balance is.
What should I do after it’s installed?
Change filters often, keep the outdoor unit clear of plants or debris, and get a yearly tune-up before summer.
