Ductless Mini-Split Installation

The cost of mini split installation depends on how many interior units you need, the length of line sets, and any electrical or prep work. A single-zone ductless system is often more affordable, while multi-zone mini split installs designed for whole house comfort require more labor and equipment. At Austin Air Conditioning, we provide free in-home consultations with all the details so you understand the price before work begins.

Yes. A ductless mini split can be designed for a single inside unit to cool or heat one room, or multiple indoor units connected to one outdoor unit for zoning across your home. This flexibility makes ductless systems ideal for additions, upstairs spaces, or areas your current HVAC struggles to reach. We design your new unit based on your home’s layout and your comfort needs.

A ductless mini split heat pump works by moving refrigerant between the inside unit and the outdoor unit. In summer, it extracts heat from the indoor air and transfers it outside to keep your space cool. In winter, the system reverses, pulling heat from outdoor air and delivering warm air inside. This process makes ductless systems efficient and dependable all year long.

Central HVAC uses ductwork to distribute conditioned air, which can lead to energy loss through leaks or poor insulation. A mini split delivers air directly into the room through an interior unit mounted on the wall. This direct approach improves efficiency, allows independent fan speed control, and avoids the expense of reworking ducts in older homes.

Yes. Because they deliver air directly to each space, ductless systems avoid energy losses common in ductwork. Many mini splits use variable-speed compressors that adjust fan speed and refrigerant flow to match demand, saving energy compared to older AC units or gas furnaces. In our region, where cooling demands are high for much of the year, this efficiency can reduce monthly costs significantly.

A ductless mini split is a type of heat pump. Both systems transfer heat instead of generating it, which makes them efficient. The key difference is how they distribute air: traditional heat pumps connect to a duct system, while a mini split uses indoor air handlers to condition spaces without ducts.

Mini split installation is straightforward when handled by an experienced HVAC company. We begin with prep work, drilling a small hole through the wall for the line set, wiring, and refrigerant lines. Indoor evaporator units are mounted securely, and the outdoor unit is set on a composite pad. Our technicians use a vacuum pump and micron gauge to pull a deep vacuum, test for leaks, and pressure test all flare connections. Once everything is correct, we complete wiring and startup, then walk you through all the details of your new system.

Most jobs take about one day. A single-zone system may be done in over an hour or two, while multi-zone systems with longer refrigerant lines can take longer. We’ll explain the plan, show you all the details upfront, and keep you updated throughout the job.

Ductless systems are flexible. They’re ideal for upstairs bedrooms, converted garages, offices, or homes without existing ductwork. We can install inside units on walls, run insulated lines through discreet holes, and connect everything to one outside unit. Our team will design a system that fits your layout and avoids mistakes that can come with diy install attempts.

Yes. Like any HVAC system, ductless mini splits need annual maintenance. We clean the inside units, check wiring, inspect refrigerant lines, and use special tools to confirm correct operation. Regular service helps prevent leaks, protects your warranty, and keeps your new unit efficient.
