The room the thermostat never sees
A lot of Harker Heights houses have a bonus room over the garage, a game room at the end of the hall, or an addition the original ducts were never sized for. Central air does its job in the living room. That leftover space still sits under a hot roof along the I-35 corridor, and it stays several degrees off from the rest of the house.
Old West Minisplits posts a flat price for a new mini split install, no standoffs and no in-home visit required to hear a number. One zone is $2,000, two zones are $3,700, three zones are $5,400. Four or more zones are quoted individually. Submit the quote form at /#quote when you are ready.
Why that room stays hot
Central Texas summers load a bonus room from every side. Heat comes through the roof, through the garage below, and through any west-facing glass. The last run of duct in a smaller Bell County house often cannot push enough air that far, so the thermostat in the hall never sees how hot that room actually is.
Closing the door makes it worse. A window unit is a stopgap that fights the same heat and still leaves a noisy box in the wall. A ductless heat pump is a dedicated zone for that one room, cooling hard in summer and covering the mild Harker Heights winter without a furnace.
The posted price for a new install
The one-zone price of $2,000 is a new install, not a repair or a service call. It includes the indoor head, the outdoor heat pump, the line set, standard electrical, refrigerant, testing, cleanup, and a Home Depot run for touch-up paint. Licensed contractors do the work. There are no trip fees and no surprise upcharges after the fact.
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 puts the number on the page first. Honest exceptions are stated up front. Those are a very long line set, a panel upgrade the house already needed, or unusually difficult mounting.
One head for one stubborn room
Most Harker Heights bonus rooms need a single indoor head. If the space is large or split into two sitting areas, two zones at $3,700 may be the cleaner answer. You decide after looking at the posted prices, not after a sales walkthrough.
Old West Minisplits does not open walls to add ducts, does not replace your main furnace, and does not do panel work beyond the standard electrical already in the flat price. If the house already needed a panel upgrade, that is a licensed electrician you arrange separately. Use the form at /#quote to start. These prices apply to new installs only.
How we compare
| Factor | Old West Minisplits | Extending the ducts |
|---|---|---|
| Upfront cost | $2,000 for one new zone, $3,700 for two, $5,400 for three | Custom quotes commonly $3,000-$6,000 per zone, or a duct add-on priced after an in-home visit |
| How you get a number | Posted on the page, then the form at /#quote | Most contractors will not quote until they walk the house |
| Comfort in that room | A dedicated heat pump head that only serves the bonus room | A longer duct run still sharing one thermostat with the rest of the house |
| Work inside the house | Line set, standard electrical, testing, cleanup, and touch-up paint in the flat price | Cutting sheetrock for new ducts, a bigger crew, and often a separate electrical bill |
Straight answers
Is the $2,000 one-zone price a repair call for a bonus room that already has a unit?
No. These flat prices are for new installs only. They are not repair or service-call prices. If you need a repair, this page does not apply.
Will one indoor head cool a bonus room over the garage?
Usually yes. Heat stacks in that over-garage space, and one dedicated zone is what most of those rooms need. If the room is a long rectangle with two living areas, two zones at $3,700 may fit better. Tell us the layout on the form at /#quote.
What can raise the posted price?
A very long line set, a panel upgrade the house already needed, or unusually difficult mounting. Standard electrical is already in the flat price. A panel upgrade is work a licensed electrician handles separately.
Does that room still need the furnace in winter?
The mini split is a heat pump. It cools through a brutal Central Texas summer and handles a mild winter without a furnace in that zone. Your existing central system can keep serving the rest of the house.
