The Installer Wants Full Payment Today — Is That Even Legal in Florida?
The new system is running, the house is finally cooling down, and the installer wants the entire balance before the truck leaves your driveway. Every instinct says something's off. But paying in full on install day is the normal version — the payment Florida law actually worries about is the deposit you'd hand over weeks earlier. There's a state statute about that one, and almost nobody who signs an AC contract has heard of it.
Why the guy who wants it all today might be the safer one
Go read what installers say to each other on trade forums when payment terms come up. Over and over you'll find the same policy: nothing due until the system is in and running, then the whole amount before the crew packs up. One contractor put it flatly — payment is due at time of service, all of it.
That sounds aggressive until you think about what already happened by that point. The equipment is bolted to your house. The company already paid its supplier for the unit and is about to pay the people who spent the day sweating in your attic. You're being asked to pay for a machine that's already cooling your bedroom.
Now flip it. A big deposit means your money leaves weeks before any of that. What you own at that moment is a signature on a proposal. Every AC horror story that ends with lawyers starts in that gap — money gone, work not started, phone going to voicemail.
The ten percent tripwire nobody mentions at the kitchen table
Florida actually wrote a law about that gap. It lives in the construction statutes — section 489.126 — and it works like a tripwire. If a contractor takes more than ten percent of the contract price up front on a residential job, the state starts a clock most homeowners never hear about: thirty days from your payment to apply for the permit.
And a permit always applies here. Swapping out a central AC in Florida takes a mechanical permit even when the new unit is the same size sitting in the same spot as the old one. So there's no version of a full-system changeout where the clock doesn't run.
Which quietly hands you something useful. The permit application is a public record — your county building department has a search page, and you can type in your own address and watch for the filing. If a company took half down and a month later there's nothing under your address, you're allowed to notice.
When the deposit goes quiet
Somebody is always on the other side of this statute. Picture the homeowner who signed in May, wrote a check for half of a five-figure job, and is now watching hurricane season roll in with the old unit still wheezing on the slab. The law gives that person a specific move, and it's quieter than you'd expect: a written demand, sent certified mail with a return receipt, telling the contractor to pull the permit and start the work — or send the money back.
From the day that letter lands, the contractor has thirty days. After that, the statute stops assuming there was a good reason for the delay, and at that point Florida law calls it theft. The charge scales with the amount of money involved, so a deposit large enough can turn a no-show contractor into a felony case.
Certified mail, return receipt requested — five words that turn a shrug into a countdown.
The boring way to never need any of this
Every mess above grew in the same place: the space between the price and the work. Money moved early, work moved late, and the statute exists to police that gap.
So close the gap. Before you sign anything, ask two plain questions — who pulls the permit, and when is the money actually due? A company with nothing to hide answers both without blinking. Terms where the money travels with the work are the terms a healthy company can afford to offer.
And you can shrink the gap before anyone's standing in your kitchen. COLD AC GUY puts the price up front — use the price tool, see your number, and decide at your own speed. Then install day is just the day you pay for a working system you already knew the cost of. The certified-mail letter stays in the drawer.
Common questions
Is it normal for an AC company to want full payment on the day of installation?
Yes — very. Many residential HVAC companies collect nothing up front and the full balance the day the system is installed and running, because by then they've already paid for the equipment and the labor. Others split it, taking roughly a third at signing and the rest at completion. The day-of payment itself is standard practice; the setup that deserves scrutiny is a large payment made weeks before any work happens.
Is there a legal limit on deposits in Florida?
There's no cap — a contractor can ask for any deposit, even the whole amount. But under Florida Statute 489.126, once an initial payment goes over 10% of the contract price on a residential job, the contractor must apply for the required permits within 30 days of receiving your money and start the work within 90 days after those permits are issued.
Do I need a permit to replace my air conditioner in Florida?
Yes. A full system changeout requires a mechanical permit anywhere in Florida, even when the new unit is the same size and type as the old one. Your contractor pulls it, and the application becomes part of your county building department's public records — which means you can verify it was filed yourself.
What can I do if I paid a deposit and the contractor never started the work?
Send a written demand by certified mail, return receipt requested, telling the contractor to apply for the permit, begin the work, or refund your payment. If 30 days pass without action, the law presumes the contractor had no just cause — and a violation of statute 489.126 is prosecuted as theft under Florida Statute 812.014, with penalties that climb from a misdemeanor to a felony depending on the amount of money involved.
How do I check whether my contractor actually pulled the permit?
Most Florida building departments run a public permit search online. Look up your county or city name plus "permit search," enter your address, and any application will be listed along with its status and inspections. If your deposit was more than 10% of the contract price and 30 days have passed with nothing on file, that's your cue to send the written demand.
