Replace your window AC with a mini split in Central Texas.

Updated September 2026

If you are tired of wrestling a heavy window unit onto the sill every spring, a ductless mini split is a permanent solution. The indoor head mounts high on the wall, freeing your window view and eliminating the gap that lets hot air and bugs inside.

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 window AC units fall short in Central Texas summers.

Window air conditioners block natural light, reduce your window opening, and often let outside air leak around the frame no matter how much foam you stuff in. In a Central Texas summer, a standard window unit struggles to keep a room below 80 degrees when the heat index climbs past 105. The compressor sits right in the window, vibrating the frame and making a constant hum that carries through the house.

A ductless mini split solves those problems. The compressor lives outside, so the indoor unit is whisper quiet. The head mounts near the ceiling, leaving your window clear and your view open. Our flat price for a single zone is $1,500 materials and labor included, and most 1-3 zone installs finish in one day. We handle the standard electrical hookup and even a Home Depot run for touch-up paint if needed.

How a mini split changes your daily comfort and routine.

Unlike a window unit that you must remove and store every fall, a mini split is a permanent fixture. It is a heat pump, meaning it cools through brutal Central Texas summers and heats through mild winters without a separate furnace. You set the temperature once and forget it. No more lifting a 60-pound unit onto a second-story sill or worrying about a storm blowing it loose.

Our installations are performed by TDLR-licensed contractors who test every system before the crew leaves. We state honest exceptions like a very long line set or a panel upgrade the house already needed before work starts, never after. For homeowners switching from window units, the upgrade is straightforward: we mount the head, run the refrigerant line, and connect the outdoor condenser. Most single-zone jobs are done by early afternoon.

Questions

Can a mini split sit in the same window opening as a window AC?

No, a mini split indoor head mounts on a wall, not in a window. The outdoor unit sits on a pad or bracket on the ground or an exterior wall. The window is freed entirely for light and use.

Do I need to hire an electrician separately for a mini split installation?

No, our flat price includes the standard electrical hookup. We connect the mini split to an existing nearby circuit that meets code. If your home needs a panel upgrade that was already deficient, we tell you before work starts.

Will a mini split cool a room that a window unit could not cool?

Yes, mini splits are sized to the room's square footage and heat load. A properly sized unit handles Central Texas triple digits much better than most window units, which are often undersized. We test the system to ensure it reaches set temperature before leaving.
