Condo AC replacement in Casselberry, Florida
Casselberry's three largest condominium developments hold 786 units, all built between 1972 and 1986, with median living areas of 781 to 1,126 sq ft. A condo changeout needs the same mechanical permit as a house, but ownership of the pad, chase and condenser location is set by the declaration.
Casselberry's condominium stock, by the numbers
| Development | Units | Median year | Median sq ft |
|---|---|---|---|
| Carrington Park A Condominium | 369 | 1973 | 1,051 |
| Oxford Square Condominium | 283 | 1986 | 1,126 |
| Marbeya Club Condo | 134 | 1972 | 781 |
786 units across three developments, every one of them built between 1972 and 1986, and all three are 100% built in the 1970–89 band. They are the two largest and the ninth-largest residential developments in the entire city. A condominium changeout is not an edge case in Casselberry — it is a substantial share of the work.

Condominium changeouts in practice
Four things that make a condo changeout a different job from a single-family one:
- Who owns what. In most Florida condominiums the air handler and the condenser serving a single unit are the unit owner’s property, but the pad, the lineset chase, the roof penetration and sometimes the condenser location are common element. Read the declaration before anyone quotes, not after.
- Small equipment, tight tolerances. Median living areas of 781 to 1,126 sq ft mean genuinely small loads. These are the units most often oversized by a rule-of-thumb swap, and a small unit that short-cycles is a mould complaint waiting to happen. Why sizing matters more here.
- Association approval. Florida law limits what an association may demand — and since HB 803 (2026), s. 720.3035 has been amended so that a homeowners’ association architectural review may not require a building permit as a prerequisite to its own approval. What an association can and cannot require.
- The permit is still yours. A condominium changeout is mechanical work. It needs a mechanical permit exactly as a house does, at the flat $200 city fee if the building is inside city limits.
