Garage Mini Split Installation, the Off Duty Way.
The conditioned garage is Central Texas’s favorite home upgrade, the gym that works in August, the shop that works in January, the hangout that works period, and the mini split is how it happens: one wall unit, one clean install day, and the hottest room on the property becomes the one everybody migrates to.
Mini Splits · Burnet & Central Texas
The Best Room You Have Not Conditioned Yet
Texas garages are thermal punishment: sun-loaded doors, uninsulated walls, black driveway radiation, and ceiling heat that turns the space into a kiln from May through September, then a cold cave through the freeze weeks. Meanwhile the square footage sits there, the biggest unconditioned room on the property, wanted for lifting, woodworking, projects, game-day, and the mini split converts it for a fraction of what an addition costs: inverter heating and cooling sized for the garage’s honest loads, independent of the house system, controlled from the phone, and cheap to run precisely because it conditions only when the space is living.
Garage installs have their own engineering honesty, and it starts with sizing: the internet charts undersize these spaces chronically because garage loads are their own category, door exposure and orientation, insulation reality, often none in the walls and worse above, ceiling height, and what the space will do, a packed gym breathing hard needs more than a storage bay. We size from the actual structure and use, and we have the insulation conversation straight: a few hundred dollars of ceiling insulation and door sealing often lets a smaller unit outperform a bigger one in a raw shell, and we would rather quote you the combination than oversell tonnage into an envelope that leaks it away.
Placement and routing respect the garage’s working life, heads clear of door tracks, dust sources, and the wall the shelving needs, linesets routed clean and protected, condensate drained properly, and the install lands in a day, Diamond craft throughout, commissioned and taught before we leave.
There is also a Hill Country layer to this work that out-of-area advice never accounts for. Limestone terrain around Burnet soaks up heat all day and radiates it back through the evening, so equipment here runs longer and later than the same unit would in a milder market. Humidity rolling off Buchanan, LBJ, and the rest of the Highland Lakes chain works on coils, drain lines, and cabinet steel every month of the year. Then winter shows up sideways: a sixty-degree afternoon collapsing into an overnight freeze finds every marginal component in the county at once. Doing garage mini split installation correctly here means doing it for this climate, with parts choices and settings that respect what Central Texas actually does to machinery.

Why Off Duty
Size It for the Garage It Is
The garage mini split failure story is always the same: a unit sized from a square-footage chart meeting a west-facing door in July, running flat-out at high speed forever, loud, strained, and losing, and the owner concluding mini splits do not work in garages, when the truth is arithmetic did not get done. Garage loads swing wildly with orientation, door count, insulation, and use, a north-facing insulated bay and a west-facing raw shell of identical square footage can differ by half a size class or more, and our assessments read the actual structure: door exposure, ceiling situation, air sealing, intended activity. The unit that comes out of that math cruises quietly through August, which is the entire difference between the conversion people brag about and the one they warn about.
The heating half deserves its Texas pitch: garage winters here are short and real, and the same unit that beats August carries January effortlessly, hyper-heat tiers available for the spaces that live year-round, which converts the garage from a seasonal room to a permanent one. Add the practical trimmings, phone control for pre-cooling before workouts, lockable settings for shared households, filter access planned around the shelving, and the garage quietly becomes what the square footage always wanted to be: the most usable room on the property, at the operating cost of a window unit done right.
Every garage mini split installation call runs the same four steps we run on everything. You call (512) 925-3090 and a real person answers, any hour of any day. We diagnose with gauges and meters, never with guesses, until the actual cause is proven. Then we explain it straight: the failure, the fix, and the exact price, in plain English, before any work starts. Finally we do the work to spec and verify it under load before the truck leaves. Temperatures checked, pressures checked, paperwork handled. It is the same process that earned the reviews on our reviews page, and it does not change based on the size of the job.
A straight word on money. We do not print teaser prices on this website and we do not do surprise math on invoices. Call, describe the problem, and we will tell you what the visit costs before a truck rolls. When the diagnosis is in, you get the full repair price out loud, before the work starts, and you decide with the real number in front of you.
Worth saying plainly: this is not a problem that ages well. Systems compensate quietly right up until they cannot, and the failure that finally announces itself usually costs more than the one caught early would have. If your gut says something is off, that instinct is worth one free phone call. The worst case is we tell you everything sounds normal, which is a pretty good worst case.
As for who shows up: this is an owner-operated shop, so the tech at your door is usually Bryce himself, a second-generation HVAC man with ten years on the tools, licensed, insured, and photographed doing exactly this kind of work in the job gallery. No commissioned salesman rides along, and nobody at this company earns a bonus for talking you into more than you need.
We run this work all over the map: Burnet and the Highland Lakes first, then the whole hundred-mile circle, Marble Falls, Georgetown, Round Rock, Austin, Killeen, and out to Waco and Boerne. The full sixteen-county roster is on the service areas page. Wherever you sit on it, the same truck standard applies: the same tech, the same instruments, the same price-before-work rule, whether the drive took ten minutes or ninety. Distance changes the arrival window, never the workmanship.

The Standard
How This Work Gets Done Here
Here is the standard this work gets held to, spelled out. First, no guessing: the cause is proven with gauges, meters, and eyes on the actual equipment before a single part is recommended. Second, no padding: the fix that goes on the quote is the fix the system needs, sized and specced properly, with no mystery add-ons riding along. Third, no shortcuts: torque specs, code clearances, and manufacturer procedure all get followed even where nobody will ever look, because that is precisely where corners usually get cut.
And when it is done, it gets proven. Systems get run under real load, temperatures and pressures get checked against spec, and the numbers get recorded so the next visit starts from data instead of memory. You get the plain-English version of what was done and why, the workspace gets cleaned, and the price on the invoice is the price you heard before the work began. Hold us to all of it. Our neighbors in the reviews already do.
Garage Mini Split Installation Questions
Asked Before We Roll a Truck
Real questions from real Central Texas customers, answered the same way we answer them on the phone: straight.
What size mini split does a 2-car garage need in Texas?
Bigger than the generic charts say and specific to your structure: a typical two-car bay lands somewhere in the middle of the residential size range, and the honest number moves substantially with door orientation, west and south exposure punish, insulation reality, ceiling included, and use, an active gym runs hotter than a parked car. Under-sizing produces the flat-out failure story; modest right-sizing produces the quiet cruise. The free look reads your actual garage in twenty minutes and quotes the size with its reasoning, often alongside an insulation suggestion that makes the whole project cheaper and better simultaneously.
Should I insulate the garage before installing the mini split?
If the ceiling is uninsulated, almost certainly, and often the door too: insulation dollars in a garage buy comfort capacity cheaper than equipment dollars do, a few hundred dollars of ceiling batts and door insulation panels can drop the space’s load enough to shift unit sizing down while improving how any unit holds temperature, and air-sealing the obvious leaks compounds it. We quote honestly around this: the assessment names your envelope’s reality, prices the equipment for the garage as-is and as-improved where the difference matters, and lets you sequence sensibly. Conditioning a raw shell works; conditioning a modestly improved one works beautifully for less.
Can the mini split handle garage dust from woodworking?
With honest management, yes: shop environments run filters on an accelerated rhythm, sawdust loads intake screens fast, placement keeps heads clear of the direct dust stream, away from the table saw’s throw, above the fray, and serious dust production deserves its own collection at the source, which protects lungs and equipment alike. The maintenance conversation gets tuned to the shop’s reality, more frequent rinses, the annual professional clean giving coil and blower the deep treatment, and machines managed this way serve shops for years. Tell us what the space builds when you call, and the design will respect it.
Will it run up my electric bill?
Less than people fear, and the inverter behavior is why: the unit conditions the garage only when the space is in use or held at economical setbacks, modulating gently at partial load rather than slamming cycles, and typical garage duty, evening workouts, weekend shop sessions, game days, meters out at modest monthly numbers, a fraction of what conditioning the space through the house system would cost even if ducting it were wise, which it is not. Phone scheduling tightens it further, pre-cool before use, coast after. The assessment can sketch your expected usage cost from the space and habits, honestly, before you commit to anything.
How long does a garage installation take?
One day, nearly always: the garage is the platform’s easiest canvas, open structure, easy routing, forgiving penetrations, and the install runs mounting, lineset, outdoor unit, vacuum, charge, and commissioning between morning and late afternoon, with the space cooling by evening. The prep conversation beforehand covers placement around your shelving and door hardware, drainage routing, and any electrical scope, most garages take the circuit easily, verified at the assessment. It is the closest thing to instant square footage this trade offers: one clean day, and the hottest room on the property changes teams permanently.
