Cool the bonus room central air cannot reach in Waco
A finished bonus room over a garage or at the far end of a Waco ranch house is the first space to lose the fight in July. The longest duct, the closed door, and the unconditioned garage below steal the cool air before it ever settles. Central Texas heat does not negotiate with a single thermostat downstairs.
Old West Minisplits posts a flat price for a new ductless mini split in that room, no standoffs and no in-home visit required to hear a number. One zone is $2,000, two zones are $3,700, and three zones are $5,400, with four or more quoted individually. These figures are for new installs only, never repairs or service calls.

Why the last room on the duct never cools
A smaller Central Texas city on the I-35 corridor still cooks through the same long summers as the rest of the state. The typical house was built around one outdoor unit sized for the original floor plan, then a bonus room, converted attic, or garage apartment was added later. Supply registers in that room are often the farthest from the air handler, so the run is long and the leftover airflow is weak.
Closing the door to keep noise in also cuts the return path. The downstairs thermostat is already satisfied, so the system shuts off while that room stays warm. A mini split is a heat pump that treats the bonus room as its own zone.
The price is posted before anyone rolls a truck
Ductless installs in Central Texas commonly run $3,000 to $6,000 per zone on a custom quote from other contractors, most of whom require an in-home visit before quoting. Old West Minisplits flat prices for new installs are $2,000 for one zone, $3,700 for two, and $5,400 for three. That covers equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and even a Home Depot run for touch-up paint.
There are no trip fees and no upcharges on the ordinary job. Honest exceptions, stated up front never buried, are a very long line set, a panel upgrade the house already needed, or unusually difficult mounting. Licensed contractors perform the work. Any panel work beyond what is included is a separate electrician job the homeowner arranges if the house already required it.
Leave the existing ducts. Condition the room you use.
Cutting new duct through a Waco garage ceiling or a tight attic chase is messy, belongs to another trade, and still leaves one thermostat in charge of two climates. A ductless head mounts on the wall, the condenser sits on a pad outside, and the line set is a small penetration. You keep the existing central system for the rest of the house.
Old West Minisplits does not tear out ducts, add insulation, or replace electrical panels as a package. If those trades are needed, the homeowner arranges them separately. What you get here is a new heat pump zone for the bonus room at a posted price. Use the form at /#quote.
How we compare
| Factor | Old West Minisplits | Extending the ducts |
|---|---|---|
| Upfront Cost | $2,000 for one new zone, posted before any visit | Other ductless quotes commonly $3,000-$6,000 per zone after an in-home visit, and duct extensions are custom bids |
| Who controls the room | Dedicated thermostat on the mini split, door can stay shut | Downstairs thermostat still calls the shots for the farthest register |
| Disruption | Wall head, outdoor pad, small line-set hole, cleanup and touch-up paint included | Open ceilings or garage soffits to pull new supply runs |
| Heat and cool | Heat pump for brutal summers and mild winters in that room | A system that already fails to cool the bonus room will not magically condition it in either season |
Straight answers
Is $2,000 the price to cool one bonus room?
Yes, for a new one-zone install. Two zones are $3,700 and three zones are $5,400. The price includes equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and a Home Depot run for touch-up paint. This is not a repair or service-call price.
Will it heat that room in a Waco winter?
A mini split is a heat pump. It cools through brutal Central Texas summers and handles the mild winters along the I-35 corridor without a furnace in that room. The existing central system still serves the rest of the house.
What if the condenser has to sit far from the bonus room?
A very long line set is an honest exception, stated up front, and would be quoted instead of the flat figure. Unusually difficult mounting is the same. Ordinary runs on a typical house stay inside the posted price.
Do I have to replace the central air to fix one hot room?
No. The mini split serves the bonus room as its own zone. The central system stays in place for the main living areas. Old West Minisplits does not demolish ducts or resize the old system.
