Independent Climate Control for Finished Basements
Updated September 2026
Basements are rare in Central Texas clay and limestone, but walkout basements and hillside foundations exist from Salado to Waco. Turning that below-grade space into a bedroom, media room, or guest suite requires dedicated climate control. Central HVAC systems rarely have the extra capacity or duct routing to handle a subterranean floor.
A ductless mini split heat pump solves the problem without tearing open ceilings for ductwork. Old West Minisplits installs them with plain pricing posted up front: 1 zone for $2,000, 2 zones for $3,700, and 3 zones for $5,400. Submit your room details at /#quote to lock in your project.
Why Central Ducts Fail Below Ground Level
Basements carry different thermal demands than the rest of the house. Earth-sheltered walls retain cool ground temperatures in summer, while upper levels take the brunt of the Texas sun. Tying a basement into your main central system leads to uneven temperatures, leaving the lower floor damp and cold while the main floor struggles.
A dedicated mini split operates on its own thermostat. It pulls humidity out of below-grade air during muggy seasons and delivers steady heating during winter cold snaps. You get comfortable living space without stressing your primary air conditioner.
Straightforward Installation on Masonry and Walkout Walls
Installing ductless equipment against stone, concrete, or framed walkout walls requires clear planning. Our licensed contractors run line sets directly to the outdoor condenser, keeping penetrations clean and sealed. Every standard installation includes the equipment, labor, standard electrical, line set, refrigerant charge, and cleanup.
These flat rates apply strictly to new installations, not repairs or maintenance visits. Honest exceptions are stated up front: an unusually long line set, difficult exterior mounting, or a panel upgrade your home already needed. We focus entirely on heating and cooling, leaving framing, drywall, and insulation to the other trades you hire.
Upfront Pricing Without Contractor Standoffs
Traditional HVAC companies treat finished basements as custom engineering jobs, charging $3,000 to $6,000 per zone. They usually require an in-home sales visit before naming a price. That approach wastes time and leaves homeowners guessing.

Straight answers
What is the flat price to install a mini split in my finished basement?
Our flat pricing for new installations is 1 zone for $2,000, 2 zones for $3,700, and 3 zones for $5,400. Projects needing four or more zones are quoted individually. The price includes the heat pump, labor, standard electrical, line set, refrigerant, testing, cleanup, and basic touch-up paint.
Can a mini split handle moisture in a below-ground room?
Yes. Mini splits are heat pumps that dehumidify while cooling. Because basement walls stay cooler than outdoor air, an independent mini split maintains comfort without overcooling the space to satisfy an upstairs thermostat.
Do these flat prices cover repairs on an existing basement AC unit?
No. Our flat rates apply strictly to brand new system installations. We do not provide repair work, component replacements, or general service calls on existing equipment.
Do you handle framing, insulation, or electrical panel upgrades for the basement?
No. Old West Minisplits handles the mini split installation and standard equipment electrical connections. Any framing, drywall, insulation, masonry structural modifications, or main service panel upgrades must be handled separately by licensed specialists.
