Mini Split Installer in Killeen, Texas, Flat $2,000 Per Zone
Updated September 2026
If you live in Killeen or anywhere in Bell County, you know what a Central Texas summer feels like. The heat sits on you. Your AC runs from May through October, and if your house doesn’t have ductwork, a garage conversion, an addition, a casita, or an older home, you’ve been stuck with window units or portable ACs that work hard, drip condensate, and block your view.
Old West Minisplits is a flat-price ductless mini split installer serving the entire I-35 corridor from Austin north to Waco and south to San Antonio. We post our prices online and stick to them. In Killeen, that means one zone for $2,000, two zones for $3,700, or three zones for $5,400. No trip fees, no in-home sales pitch, no surprise add-ons. We do the job, clean up, and even make a Home Depot run for touch-up paint if needed.
What the Flat Price Actually Covers
The $2,000 per zone price includes the equipment, labor, line set, standard electrical, refrigerant, testing, and a full cleanup. It also includes a Home Depot trip to grab touch-up paint for the wall around the line-set cover, because we know Killeen homes aren’t showrooms, and a little spackle and paint go a long way. We don’t add trip fees, mileage charges, or quoting costs. The only honest exceptions we tell you about upfront are a very long line set (rare in most homes), a panel upgrade your house already needed, or an unusually difficult mounting surface like solid stone. We never tack on charges after the fact.
Typical Killeen Installations We Do
Most of our Killeen jobs are in homes without existing ductwork, ranchers built in the 60s, garage workshops, finished attics, and backyard casitas. We also install in rental properties where landlords want efficient cooling without cutting into walls. The mini splits are heat pumps: they cool through brutal Central Texas summers and handle our mild winters without a furnace. A single head unit can cool a 500–600 square foot room, and a three-zone setup can cover the main living areas of a typical Killeen 1,200–1,500 square foot home. No duct modifications. No hole in the wall for a window unit. Just quiet, efficient temperature control.
Why We Don’t Quote Per Job Like Most Contractors
Most local HVAC contractors operate on a custom-quote model. In Central Texas, ductless mini split installations commonly run $3,000 to $6,000 per zone on a quote basis. That usually requires an in-home sales visit, a lot of waiting, and a final number that can shift. We don’t do that. We price per zone because installation cost doesn’t vary much across the I-35 corridor. Whether we’re working in Killeen or San Antonio, the labor and materials are the same. So we publish a price and stick with it. You know exactly what you’ll pay before you call.

Straight answers
How much does a mini split cost in Killeen?
Old West Minisplits installs a single zone for $2,000, two zones for $3,700, and three zones for $5,400. That includes equipment, labor, line set, electrical, refrigerant, testing, and cleanup. No hidden fees.
Do I need ductwork for a mini split?
No. Mini splits are ductless. They connect an outdoor compressor to one or more indoor air handlers through a small line set. This makes them ideal for Killeen homes without existing ductwork, additions, garages, and casitas.
Can a mini split handle a Central Texas winter?
Yes. Mini splits are heat pumps, meaning they reverse cycle to provide heat. They work well down to about 20°F, which covers the vast majority of Bell County winter days. You won’t need a separate furnace.
