Attic fans move heat around. Mini splits take it outside.
By mid-afternoon the upstairs in Killeen, Temple, and Waco is a different climate from the first floor. Homeowners hang a whole-house fan in the hall ceiling or a ventilator in the attic and hope the heat leaves. Those machines move air. They do not condition it.
A ductless mini split is a heat pump that pulls heat out of the room and dumps it outdoors. Old West Minisplits posts a flat price for new installs only, 1 zone $2,000, 2 zones $3,700, 3 zones $5,400, with four or more zones quoted individually. That figure includes equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and a Home Depot run for touch-up paint, with no trip fees. The price is posted up front, no standoffs. Start at /#quote.
What whole-house fans and attic fans actually do
A whole-house fan sits in the ceiling and yanks indoor air into the attic and out the vents. The bet is that cooler night air will replace it through open windows. An attic fan, gable or roof mount, tries to flush the attic so less heat soaks through the drywall into the rooms below.
Neither unit has a compressor or a coil. Neither one holds a thermostat temperature in the bedroom. On a still July night along I-35, outdoor air often stays warm and wet, so the fan is moving the same heat you already had, plus humidity.
How a mini split treats a hot upper floor
The indoor head mounts on the wall of the room that actually overheats, the bonus room, the upstairs landing, or the converted attic you now sleep in. Refrigerant in the line set carries that heat to the outdoor unit. Windows stay closed. The space dries as it cools, which matters as much as the number on the thermostat in Belton, Harker Heights, and Copperas Cove.
Licensed contractors run the install, and one miserable room is 1 zone at $2,000, two rooms $3,700, three $5,400. Honest exceptions sit in the open: a very long line set, a panel upgrade the house already needed, or unusually difficult mounting. This is new-install pricing, never a repair or service-call number.
Keep ventilating the attic. Stop expecting it to cool the bedroom.
A hot attic still deserves ventilation and insulation. That work belongs to a roofer or an insulation crew you arrange separately. Old West Minisplits does not pull attic fans, blow cellulose, or tear out ducts. A mini split can make the occupied room livable even if the rafters above it stay hot.
Other ductless jobs in Central Texas commonly run $3,000 to $6,000 per zone on a custom quote after an in-home visit. Old West Minisplits puts the number on the post before anyone drives to Jarrell, Salado, or Waco. Use the form at /#quote if the upstairs has stopped being usable in summer.
How we compare
| Factor | Old West Minisplits | Attic or whole-house fan |
|---|---|---|
| Upfront Cost | New install only: 1 zone $2,000, 2 zones $3,700, 3 zones $5,400, posted before the visit | Usually a lower hardware bill. You are buying air movement, not a cooling system. |
| What happens to the heat | Heat pump moves heat out of the room to the outdoor unit | Moves air through the house or attic. Heat stays in the air unless night air outdoors is cooler. |
| Closed house on a 100-degree afternoon | Windows stay shut. The upstairs gets a set temperature. | Whole-house fans want open windows. Afternoon outdoor air is often hotter than the house. |
| Humidity and mild winter | Dehumidifies as it cools. Reverses as a heat pump for mild winters without a furnace. | No dehumidification and no heat. Night and shoulder-season air mover at best. |
Straight answers
Is the $2,000 one-zone price for swapping a fan or for a new mini split?
It is for a new mini split install only. Old West Minisplits does not repair fans, service existing systems, or run service calls. The $2,000, $3,700, and $5,400 figures cover new 1, 2, and 3 zone installs, including equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and touch-up paint. Four or more zones are quoted individually at /#quote.
Will a whole-house fan make an upstairs bedroom sleepable in August?
It can help at night if outdoor air is cooler than the house and you are willing to open windows. On the I-35 north corridor that bet usually fails in summer. A mini split heat pump cools and dries the room with the house closed.
Can I leave my attic fan and add a mini split in the room below?
Yes. The fan handles attic air. The mini split handles the occupied room. You arrange any attic-fan, insulation, or roofing work separately. We mount the indoor head in the living space and the outdoor unit outside.
Do I still need a furnace if a mini split cools the upstairs?
Mini splits are heat pumps. They cool through brutal Central Texas summers and handle mild winters without a furnace. If a utility rebate or tax credit is on the table, verify current numbers with your provider, a licensed electrician, or the IRS. We do not quote those figures here.
