Outfitting a Duplex with Mini Splits in Austin: Per-Door Economics
Updated September 2026
Outfitting a duplex in Austin with ductless mini splits is a per-door decision. Mini Split Reef posts a flat rate of $2,000 per mini split installed, however many units. That means a duplex owner can price one unit per side at $2,000, two per side at $4,000 per side, and know the number before work begins.
Service is available across Austin and the I-35 corridor, north to Waco and Killeen and south to San Antonio, with the same flat rate corridor wide. Property managers, landlords and multi unit owners receive a volume discount off the $2,000 per unit rate.
Per-door economics for a duplex
A one zone install in each unit costs $2,000 per mini split, or $4,000 for the two sides. A two zone install in each unit costs $8,000 total. The per-door rate stays the same whether you outfit one side or the whole building. Most local HVAC contractors quote ductless installs at $3,000 to $6,000 per zone on a custom quote, which makes per-door budgeting harder before a site visit. With Mini Split Reef, the flat rate removes that variable for duplex owners and property managers.
What the flat rate covers and the honest exceptions
The $2,000 per mini split installed rate includes equipment, labor, line set, standard electrical, refrigerant, testing and cleanup. It also includes a Home Depot run for touch up paint. There are no trip fees and no surprise add ons after work starts.
The exceptions are stated up front: a very long line set, a panel upgrade the house already needed, or unusually difficult mounting. These are the only honest exceptions. Everything else falls under the flat rate.
Ductless performance for Central Texas duplexes
Mini splits are heat pumps. They cool through brutal Central Texas summers and handle mild winters without a furnace. For a duplex, this means each side can have independent heating and cooling without adding ductwork or a furnace to the building.
Mini Split Reef installs across the Austin area and the I-35 corridor, from Waco and Killeen in the north to San Antonio in the south, at the same flat rate corridor wide.
