Keep Your Pool House Dry and Cool with a Mini Split.

Updated September 2026

A pool house collects moisture from wet towels, swimsuits, and splashes all day. A ductless mini split removes humidity while cooling the space, so it’s ready for the next gathering without musty odors or sticky air.

Flat pricing, same everywhere we work

Every install is wired to code by our TDLR-licensed contractor. Long line-set runs, panel upgrades or unusual mounting can add cost, and we tell you up front, before any work starts. For market context, see our Austin mini split cost guide: typical Central Texas quotes run $3,000 to $5,000 for a single zone.

Why Pool Houses Need More Than Just Cooling

Pool houses see constant humidity from wet surfaces and evaporation. A traditional window unit may cool the air but won’t remove enough moisture to prevent mold or mildew. Mini splits dehumidify as they cool, cycling air through a refrigerant coil that condenses water vapor before it settles on walls or furniture. This keeps the space dry between uses, even when the door stays closed for days.

Most pool houses in Central Texas are small, detached structures with limited electrical capacity. A single-zone mini split at $1,500 fits the space and budget, while a two-zone system at $2,500 can handle separate areas like a changing room and storage. The flat pricing covers the unit, line set, electrical hookup, and testing, no surprises for standard installations.

Installation Considerations for Pool Houses

Pool houses often lack existing ductwork, making mini splits an ideal solution. The outdoor condenser can be mounted on a concrete pad or wall bracket, while the indoor unit goes on an interior wall or ceiling. Line sets typically run through an exterior wall, avoiding the need for visible conduit. If the structure has a finished interior, the crew will patch and paint the exit point to match the wall.

Most pool house installs finish in a single day. TDLR-licensed contractors handle the work, including the standard electrical hookup to an existing circuit or subpanel. If the house needs a panel upgrade or a longer line set, those exceptions are discussed upfront. The crew tests the system before leaving to ensure it cools and dehumidifies effectively, even in high-humidity conditions.

Questions

How many BTUs should a pool house mini split have?

A 12,000 to 18,000 BTU unit usually suffices for a typical 200 to 400 square foot pool house. The exact size depends on insulation, window exposure, and how often the door is opened. A single-zone system at $1,500 typically includes a unit in this range.

Will a mini split run all day to keep the pool house dry?

Mini splits cycle on and off like any AC, but they run longer in humid conditions to remove moisture. The system’s dehumidification mode can be set to maintain a target humidity level, usually between 50% and 60%, without overcooling the space.

Can the mini split be installed on the ceiling instead of the wall?

Yes, ceiling-mounted cassettes or ducted units are options if wall space is limited. These require a slightly larger opening for installation but provide even airflow across the room. The $1,500 flat rate applies to standard wall-mounted units; ceiling installations may involve additional labor.
