Mini Split Installation in Brentwood, Austin, Flat Price from $2,000
Updated September 2026
Brentwood, in north-central Austin, is full of small mid-century bungalows built in the 1950s, the kind of compact, efficient houses that attract young professionals and grad students looking for something affordable within bus range of the University of Texas. Those homes were built long before modern central air was standard, and a lot of them still lean on window units, especially in back bedrooms and detached garages that were never part of the original footprint.
A ductless mini split solves that without a major renovation. Old West Minisplits prices installs flat, the same in Brentwood as anywhere along our service area: $2,000 for one zone, $3,700 for two zones, $5,400 for three zones, covering equipment, labor, line set, standard electrical, refrigerant, testing, and cleanup. Get that number through the quote form on our homepage. No home visit, and no phone number to call.
What the Flat Price Covers (and What It Doesn't)
The $2,000 per zone price is all-in for a standard installation. 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 make a trip to the hardware store for paint to match the wall after we run the line set. There are no trip fees or hidden charges.
We tell you three honest exceptions before you commit, never after. A very long line set, over 50 feet, adds a materials charge. A panel upgrade that the house already needed is not included. Unusually difficult mounting, like brick or stone that requires special anchors, may add a small fee. We tell you upfront so you can decide. If your system breaks down later, we do not offer repair or warranty service. But if you are chasing repairs on a failing or poorly installed unit, getting a flat-price new install quote is often the smarter move.
Typical Brentwood Jobs: Mid-Century Bungalows and Detached Garage Workshops
Brentwood's small mid-century homes commonly need a single zone for a primary bedroom or living area that a central system, if one exists at all, struggles to keep comfortable. Because these houses are compact, a one-zone or two-zone install is often enough to cover the whole living space without needing a larger, more expensive multi-zone system.
Detached garages are common on Brentwood's older lots, and a lot of owners use them as workshops, home gyms, or extra living space for a tenant. Since these structures were never wired for cooling, a mini split with its own dedicated circuit is typically the fastest and least invasive way to make a detached garage usable through a Texas summer.
Why Flat Pricing Matters Near Campus
Most local HVAC contractors work off a custom quote. Someone visits, measures, and eventually emails a number, and that number can land anywhere from $3,000 to $6,000 per zone depending on who shows up and how the conversation goes. Old West Minisplits skips that. The price is posted on the site, you can request a quote without waiting for a home visit, and you can schedule an install date without ever picking up the phone, because we do not list one. The form on our homepage is the way in.
Whether the address is in Brentwood or anywhere else along the I-35 corridor between Waco and San Antonio, the price per zone does not change. One zone is $2,000, two zones is $3,700, three zones is $5,400. No travel surcharge for being close to campus, no discount for being farther away, just one flat number.

Straight answers
How much does a mini split cost in Brentwood?
Our flat installed price is $2,000 for one zone, $3,700 for two zones, and $5,400 for three zones. That covers a standard installation from start to finish. Most quote-based contractors serving Brentwood charge $3,000 to $6,000 per zone for a custom install.
Do I need ductwork for a mini split?
No. Mini splits are ductless. They connect an outdoor condenser to one or more indoor units with a small refrigerant line, which is why they work so well in Brentwood, where a lot of the housing stock was never built with central ducts.
How do I schedule an installation?
Go to our website and fill out the quote form. We review the details and send a confirmation. No phone calls needed, we do not list a phone number, so the form is the way to get started.
What if the property needs electrical work?
Standard electrical work is included in the flat price: a dedicated circuit, breaker, and wiring to the unit. If the property needs a panel upgrade it already needed for other reasons, for example an old fuse box, that is not included. We tell you before you agree so there are no surprises.
Is a single zone enough for a small Brentwood bungalow?
Often, yes. Many of Brentwood's mid-century homes are compact enough that one or two properly sized zones cover the whole living space, which keeps the project at the lower end of our flat pricing.
Can you install a mini split in a detached garage workshop?
Yes. A detached garage with no existing electrical or cooling connection is a standard job for us, and the dedicated circuit needed for the mini split is included in the flat price.
