ADU Mini Split Installation Near UT Austin, Flat Price from $2,000
Updated September 2026
Austin has made it easier over the past several years to build and rent out accessory dwelling units, and backyard cottages, converted garages, and small standalone units have become a common way for owners near the University of Texas to add a second income stream, often to a grad student or young professional tenant looking for something smaller and quieter than a big student rental. An ADU is, almost by definition, a small footprint with no connection to the main house's ductwork, which makes central air impractical and a ductless system the obvious choice.
Old West Minisplits installs ADU mini splits at the same flat price as any other property: $2,000 for a single zone, which covers most ADUs outright, up to $3,700 or $5,400 for larger units with multiple rooms. That price includes equipment, labor, line set, standard electrical, refrigerant, testing, and cleanup. Get a quote through the form on our homepage, no phone call, no home visit required.
What the Flat Price Covers (and What It Doesn't)
The $2,000 per zone price is all-in for a standard installation, and it is the same price whether you own one rental or a dozen. It includes the mini split heat pump unit, indoor air handler, line set, wiring, breaker, refrigerant, a condensate pump if needed, testing, and cleanup. We also touch up paint where the line set runs so the unit does not look like an afterthought at the next showing or lease renewal. No trip fees, no hidden charges, and no sales visit required just to get a number.
Three honest exceptions apply, and we flag them before you commit, never after the crew is on site. A very long line set, over 50 feet, adds a materials charge. A panel upgrade the property already needed is not included. Unusually difficult mounting, such as brick or stone exteriors that need special anchors, may add a small fee. We do not offer repair or warranty service on existing systems, but if a unit is failing or was installed poorly by someone else, a flat-price new install is often the cheaper long-term call than another service ticket.
Typical ADU Jobs: Small Footprint, Single Zone, Independent Electrical
Most ADUs are compact by design, one or two rooms, so a single-zone mini split is usually enough to properly heat and cool the whole space, which puts most ADU installs at our lowest price point. Because there is no existing ductwork to fight, the install is typically a clean, single-day job.
Owners renting out an ADU near campus often want the unit's electrical usage kept separate from the main house, similar to a duplex, and a dedicated circuit for the mini split supports that. We plan and wire that circuit as part of the standard flat-price install rather than treating it as an upgrade.
Why Flat Pricing Works Better for Owners
A custom quote means scheduling a salesperson around a tenant's calendar, waiting on a bid, and hoping the number that comes back fits what you budgeted for the unit. Old West Minisplits skips the walkthrough. The price is posted, so you can pencil it into a renovation budget or a turnover schedule before you talk to anyone, and you never have to call anyone, because we do not publish a phone number. The quote form on our homepage is the only step between you and a scheduled install.
The price per zone holds whether the property sits blocks from campus or anywhere else along the I-35 corridor from Waco to San Antonio. One zone is $2,000, two zones is $3,700, three zones is $5,400, the same number for every unit in a portfolio, which makes budgeting across several properties simple.

Straight answers
How much does a mini split cost per unit?
Our flat installed price is $2,000 for one zone, $3,700 for two zones, and $5,400 for three zones, the same price whether it is your only property or one of several. That covers a standard installation from start to finish, no per-project sales visit required to get the number.
Do you require a home visit to give me a quote?
No. Fill out the form on our homepage with the property details and zone count, and we send back the price. That makes it easy to budget across a rental, a turnover schedule, or a small portfolio without coordinating a visit for every property.
How do I get in touch or schedule a job?
Through the quote form on our homepage. We do not list a phone number for the business, so there is no call to make, just the form and a confirmation once details are set.
What is not included in the flat price?
Three things: a very long line set over 50 feet, a panel upgrade the property already needed regardless of the mini split, and unusually difficult mounting like brick or stone that needs special anchors. We flag any of these before you agree, never after the job starts.
Is a mini split really the only practical cooling option for an ADU?
For most ADUs, yes. Since these units are standalone with no connection to a main house's ductwork, running new duct systems into a small backyard structure is rarely practical or cost effective compared to a ductless mini split.
Can the ADU's electrical be kept separate from the main house?
In many cases, yes. We can wire the mini split's dedicated circuit to keep the ADU's usage separate, which is a common setup for owners who want independent billing between the ADU and the main house.
