Quick answer

PTAC and wall unit service covers packaged terminal air conditioners and heat pumps, plus through-wall AC units, in condos, hotels, apartments, efficiencies and offices. Common Miami problems are clogged coils and drains, failed fan motors, bad control boards, and salt corrosion on the outdoor side. Worn units are replaced like-for-like to fit the existing wall sleeve.

Written by Sylvia Denton, HVAC Guides Editor. Updated 2026-09-22.

A PTAC is a self-contained air conditioner, often with a heat pump or electric heat strip, that sits in a metal sleeve through an exterior wall. Everything is in one box: compressor, both coils, fans and controls. Through-wall units are similar but simpler. Both are common in older Miami Beach and Brickell condos, hotels along Collins Avenue, apartment buildings, garage efficiencies and small offices.

Because the whole system sits in one box that faces the weather on one side and the room on the other, these units take a beating in Miami. The outdoor coil gets salt and dust, the indoor coil and drain pan stay wet, and the fan motors run long hours. Most problems are maintenance problems: dirty coils, clogged drains, and filters that were never cleaned.

When a unit is past repair, the replacement has to fit the existing wall sleeve and electrical. PTACs come in a standard 42-inch sleeve size, which makes like-for-like swaps straightforward. Through-wall units vary more, and we measure the sleeve before ordering.

How PTAC service works

    Unit removed from the sleeve so both coils, the pan and fans can be reached.

    Coils, drain pan and fan wheels cleaned; drain path cleared.

  3. 3

    Test

    Compressor, fan motors, controls and heat checked.

  4. 4

    Repair or replace

    Failed parts replaced or a matched unit installed in the existing sleeve.

  5. 5

    Reinstall and seal

    Unit reset in the sleeve with a proper tilt for drainage and gaskets sealed.

Local context

PTACs in Miami buildings

Coastal buildings along Collins Avenue, Brickell Bay Drive and Key Biscayne expose the outdoor side of every PTAC to salt spray. Coils corrode and fins crumble years sooner than inland. Units with coated coils and regular fresh-water cleaning last noticeably longer.

Efficiencies and garage apartments across Little Havana, Hialeah and Westchester often run through-wall units that were installed without much thought for drainage. Water that should drip outside ends up on the floor inside. Setting the unit with the correct outward tilt fixes most of those leaks.

For hotels and condos, the value is in scheduled maintenance. Units that are cleaned twice a year break down far less often and use less power.

FAQ

PTAC questions

What is a PTAC unit?

A packaged terminal air conditioner: a self-contained unit that sits in a wall sleeve and cools, and often heats, a single room.

How often should a PTAC be cleaned in Miami?

At least twice a year, with filters rinsed monthly during summer.

Can a PTAC be replaced without changing the wall sleeve?

Usually yes. Most PTACs use a standard 42-inch sleeve, so new units slide into the existing opening.

Why is my wall AC leaking inside?

Usually a clogged drain or a unit tilted inward. Correcting the tilt and cleaning the pan stops most leaks.

Do you service PTACs for hotels and property managers?

Yes. We schedule multi-unit service in batches for hotels, condos and apartment buildings.
