Mini Splits for Converted Attics and Bonus Rooms
Updated September 2026
Converted attics and bonus rooms around Austin typically lack ductwork and become too hot in summer. Mini Split Reef installs a ductless mini split heat pump to condition just that space at a flat $2,000 per unit.
That price includes equipment, labor, line set, standard electrical, refrigerant, testing, cleanup and a Home Depot run for touch up paint. There are no trip fees or surprise add ons. The only exceptions, stated up front, are a very long line set, a panel upgrade the house already needed, or unusually difficult mounting. The same flat rate applies across the I-35 corridor from Waco and Killeen south to San Antonio. Property managers, landlords and multi unit owners receive a volume discount.
Why a mini split for an attic or bonus room
Finished attics and bonus rooms rarely have supply ducts. Running new ductwork would require opening walls or ceilings that are already complete. A mini split needs only a small penetration for the line set. These units are heat pumps, so they cool during brutal Central Texas summers and provide heat in mild winters without a furnace.
