Replace Your Portable AC with a Quiet Mini Split in One Day.
Updated September 2026
Portable AC units drip condensate, block windows with hoses, and struggle when outdoor temperatures climb past 95 degrees. A ductless mini split runs quietly, cools efficiently, and installs in a single day without tearing up walls or requiring ductwork.
Flat pricing, same everywhere we work
| System | Flat price, installed | Included |
|---|---|---|
| One split (single room) | $1,500 | Indoor head, outdoor condenser, line set, standard electrical, all labor |

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 Portable AC Units Fall Short in Central Texas Heat
A portable AC unit vents hot air through a hose out a window, but that same window gap lets heat back in. Condensate pans overflow, leaving puddles on hardwood floors. Once outdoor temperatures hit the mid-90s, the unit runs constantly, driving up electricity bills while barely keeping indoor temperatures below 80 degrees. The noise from the compressor and fan makes it hard to sleep or focus on work.
Mini splits solve these problems without ductwork. The indoor unit mounts on a wall or ceiling, connected to an outdoor compressor by a small refrigerant line. Installation includes materials, labor, and a Home Depot run for touch-up paint if needed. Flat pricing starts at $1,500 for one zone, $2,500 for two, and $3,500 for three, with no surprises after the work begins.
What to Expect During a Mini Split Installation
Most installations finish in a single day. The crew drills a 2.5-inch hole through the wall for the refrigerant line, mounts the indoor unit, and secures the outdoor compressor on a pad or bracket. Electrical work is limited to a standard hookup, though a panel upgrade may be needed if the existing circuit can’t handle the load. The system is tested before the crew leaves to ensure it cools and heats properly.
TDLR-licensed contractors handle every installation. Honest exceptions, like a long line set or difficult mounting, are discussed upfront. Mini splits function as heat pumps, providing cooling in summer and heat in winter without a separate furnace. The flat pricing covers all labor, materials, and any necessary touch-up paint, so there’s no need for an in-home quote or follow-up charges.
Questions
How much does it cost to install a mini split if I only need one zone?
A single-zone mini split installation costs $1,500, including materials, labor, and a Home Depot run for touch-up paint if needed. This flat rate applies to new installs only, with no hidden fees or additional charges after the work begins.
Will a mini split work during a Central Texas winter?
Yes. Mini splits are heat pumps, which means they provide both cooling and heating. They handle mild Central Texas winters efficiently without requiring a separate furnace, though performance may drop in extreme cold below freezing.
Do I need to be home during the installation?
Most installations finish in a single day, and the crew will need access to the home to drill the line set hole, mount the indoor unit, and test the system. If you can’t be present, you’ll need to arrange for someone to let the crew in and provide access to the work areas.
