Who permits an AC changeout at a Casselberry address

Q: Do I Need a Permit to Replace My AC Unit in Florida?

Yes, and in Casselberry the more useful question is who issues it . If your address is inside Casselberry city limits, the City of Casselberry Building Division at 95 Triplet Lake Drive issues it, at a published flat HVAC fee of $200.00. If your address is in one of the unincorporated pockets that carries a Casselberry mailing address — Deer Run, Fern Park and ZIP 32730 among them — the Seminole County Building Division in Sanford issues it instead. The permit is the contractor's job to pull, not yours, but the fee appears on your quote and a permit filed at the wrong desk stalls the job.

An air conditioning changeout in Casselberry needs a mechanical permit. If your address is inside the city limits, the City of Casselberry Building Division issues it at a published flat fee of $200.00. If your address is in one of the unincorporated pockets that carries a Casselberry mailing address — Deer Run and Fern Park among them — Seminole County issues it instead. This page tells you which one is yours.

Step one

Work out your jurisdiction before anything else

Casselberry is 7.51 square miles containing more than 30 lakes and ponds, and the boundary weaves around them. That is the real reason jurisdiction changes street by street here — the city grew around water, and it annexed and de-annexed land along the way.

The most reliable non-technical check is your utility bill:

City of Casselberry water and sewer bill — you are almost certainly inside the city, and the city permits your changeout.
Seminole County water and sewer bill — you are in unincorporated county, and the county permits it.

That is a strong indicator, not a legal determination. Before we apply, we confirm jurisdiction from the parcel record. As one Florida permitting guide puts it: your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply.

Step two

What the city actually needs, and how long it takes

Casselberry does not require contractors to register with the city in advance. It does require that every permit application carry, uploaded with it:

A current Florida state licence
Workers’ compensation coverage naming the City of Casselberry as certificate holder, or an exemption certificate
General liability insurance naming the City of Casselberry as certificate holder
A business tax receipt

The city’s own FAQ says to allow a minimum of five to seven business days for a residential permit, and the Building Division is closed on Fridays. For a planned changeout, that is the real calendar: a week of permit time on a four-day counter week.

What that means for an emergency. A house with no cooling in August is not going to wait a week. Ask any contractor how they handle it and listen for a straight answer about the sequence — the permit is still required either way, and a contractor who tells you the job does not need one is telling you something useful about how they work.

In effect since 1 July 2026

HB 803 does not exempt your air conditioner.

Florida HB 803 (2026) — chapter 2026-63, effective 1 July 2026 — requires local governments to exempt single-family work valued under $7,500 from permitting. Read the next sentence before you get any ideas. The exemption “does not apply to… any electrical, plumbing, structural, mechanical, or gas work performed on property containing a single-family dwelling” (s. 553.79(1)(g)2.b.). An AC changeout is mechanical work. It is excluded, at every price.

The same bill did add a faster permit clock: a local government must act within five business days on a mechanical permit for an existing single-family home — but only where the value of the work is under $15,000 and the applicant uses the local government’s own plans reviewer (s. 553.792(1)(a)1.). Plenty of full changeouts now exceed $15,000, and those fall under a longer tier. Read more on our permits and inspections page.

A myth worth killing

Seminole County is not in the High-Velocity Hurricane Zone.

The HVHZ is Broward and Miami-Dade counties only, defined that way in the 2023 Florida Building Code — Residential, R202. Condenser tie-downs and wind-load requirements absolutely apply in Seminole County under the regular code, and they matter in a county whose hurricane season peaks around 10 September. But if a quote cites HVHZ requirements for a Casselberry address, the person who wrote it has copied it from a South Florida template.

Step three

The portals

The city publishes two different permit systems in two different places: its Building Division page points to a CitizenServe portal, and the city FAQ points applicants to a Click2Gov building permit portal for scheduling and cancelling inspections and checking permit status. Both appear to be live, likely for different functions.

Seminole County runs its own Click2Gov building permit portal.

Why we care this much

The permit is not paperwork theatre

A permitted changeout gets inspected. An inspection is a second set of eyes on the work you just paid four or five figures for, and it is the only part of the transaction that is not sold to you by the person doing the work.

It also protects the sale of your house. An unpermitted mechanical change shows up at closing, and resolving it after the fact — with the installing contractor gone — is materially worse than paying the $200 at the time.

And it is a licensing matter. Florida requires the contractor’s certification number to appear in every advertisement, in any medium, under s. 489.119(6)(b) — website included. You can check any Florida contractor’s licence yourself at the DBPR licensee search before you let them pull a permit in your name.

FAQ

Permit questions

Are Permits Needed To Replace AC In Florida?

Yes. Replacing a condenser, an air handler, both, or a package unit is mechanical work requiring a permit from the building department with jurisdiction over the address. There is no dollar-amount exemption in Florida for this work. The permit exemption for single-family work under $7,500 created by HB 803 (2026) does not help, because it expressly excludes ‘any electrical, plumbing, structural, mechanical, or gas work’ — s. 553.79(1)(g)2.b., Fla. Stat. A changeout is mechanical work, and the disconnect makes it electrical work too, so it is excluded twice over at any price.

Do I Need a Permit to Replace My AC Unit in Florida?

Yes, and in Casselberry the more useful question is who issues it. If your address is inside Casselberry city limits, the City of Casselberry Building Division at 95 Triplet Lake Drive issues it, at a published flat HVAC fee of $200.00. If your address is in one of the unincorporated pockets that carries a Casselberry mailing address — Deer Run, Fern Park and ZIP 32730 among them — the Seminole County Building Division in Sanford issues it instead. The permit is the contractor's job to pull, not yours, but the fee appears on your quote and a permit filed at the wrong desk stalls the job.
