Conditioning a Casita, ADU, or Guest House in Austin
Mini Split Reef installs ductless mini splits in casitas, ADUs, and guest houses across Austin and the I-35 corridor. The posted flat rate is $2,000 per mini split installed, however many units. That includes equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and a Home Depot run for touch up paint. There are no trip fees and no surprise add-ons for standard installs.
Ductless installs in Central Texas commonly run $3,000 to $6,000 per zone on a custom quote, and most local HVAC contractors are quote based and require an in-home sales visit. Mini Split Reef keeps the same flat rate corridor wide, from Waco and Killeen in the north to San Antonio in the south. Property managers, landlords, and multi-unit owners get a volume discount off the $2,000 per unit rate.
Why a ductless heat pump fits a casita or ADU
A mini split is a heat pump, so it cools through brutal Central Texas summers and handles mild winters without a furnace. That matters for a casita, ADU, or guest house where adding ductwork can be expensive and space is limited. A single indoor unit can condition an open studio or one-bedroom layout, and multiple units can serve separate rooms without sharing ducts.
What the flat rate covers
The $2,000 per mini split installed 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 and no surprise add-ons. The same flat rate applies across the service area, from Austin north to Waco and Killeen and south to San Antonio. Property managers, landlords, and multi-unit owners get a volume discount off the $2,000 per unit rate.
Honest exceptions, stated before the work
Some jobs genuinely cost more. Mini Split Reef states exceptions up front, never after the fact. A very long line set, a panel upgrade the house already needed, or unusually difficult mounting can change the price. If any of those apply to your casita or guest house, you will know before work starts.

Straight answers
Can one mini split handle a casita or guest house?
Yes. Mini splits are heat pumps, so one system can cool through brutal Central Texas summers and handle mild winters without a furnace. A standard casita or ADU often needs one indoor unit, while larger or divided spaces may need more.
Is the $2,000 flat rate real for Austin and the I-35 corridor?
Yes. The flat rate is $2,000 per mini split installed across the service area, from Austin north to Waco and Killeen and south to San Antonio.
What could change the price?
The only honest exceptions are a very long line set, a panel upgrade the house already needed, or unusually difficult mounting. Those are stated up front, never after the work begins.
Do you offer a discount for multiple units or rental properties?
Yes. Property managers, landlords, and multi-unit owners get a volume discount off the $2,000 per unit rate. Mention the project size when you reach out.
