Mini-Splits, Diamond Standard.
Nine ductless services under the credential that matters: Mitsubishi Diamond Contractor training, twelve-year warranties on our installs, and factory-standard service on every brand of mini-split the Hill Country has bolted to a wall.

The Hill Country Was Built for Ductless
Stone houses that would be wounded by retrofitted ductwork. Garage shops and barn offices on every ranch property. Casitas, boathouse rooms, and additions stacked across generations of lake-house ownership. This county is practically a catalog of buildings that want exactly what a mini-split does: real heating and cooling, one room at a time, with nothing but a small line-set penetration. It is why the ductless side of this company runs deep enough to earn Mitsubishi’s top contractor tier.
The pages below cover the working life of that equipment: repair for the blinking lights and iced coils, cleaning that most owners skip until output collapses, refrigerant service for the leaks that kill compressors slowly, replacement when a unit has served its time, and the mounting variants, wall, ceiling cassette, floor, that let the equipment fit the room instead of the other way around.
The credential deserves a plain-English sentence: Diamond Contractor status is earned through factory training and audited work, and what it buys you is a twelve-year parts and compressor warranty on our Mitsubishi installs, roughly double the base coverage on the exact same equipment installed by a standard shop. Install quality decides everything on ductless, flare joints, deep vacuum, careful commissioning, and the warranty is the manufacturer betting on its own training. We bring the bet to your project.
Service-wise, the honest note is about cleaning: mini-splits are precision machines that ingest room air constantly, and their blower wheels and coils foul in ways owners never see behind the tidy cover. Output falls gradually, the machine works harder, and eventually the blinking-light call happens. The deep-clean service below restores capacity dramatically, and on the humid lake shores it belongs on a rhythm, not a someday list.
We also take over orphaned systems constantly, units installed by vanished contractors, big-box purchases that never ran right, DIY installs that need rescue. Every brand, diagnosed at factory standard, warranty status untangled where the paperwork allows. If your mini-split has been a mystery since the day it went in, that mystery usually has a findable cause.

How This Work Gets Run
Here is what hiring us for this work looks like, start to finish: a phone call that reaches a person who can actually diagnose, an honest window with the drive figured in, instruments on the system until the real cause shows itself, a straight explanation with the real price attached, your go-ahead before anything happens, and verification before departure. The same standard covers a two-mile call in Burnet and a sixty-mile call at the edge of the map, because distance changes the drive and nothing else about the work.
Money gets handled the Burnet way on every page in this category: the visit cost stated on the phone before a truck rolls, the repair or install price stated after diagnosis and before work, no surprise line items, and no commission structure anywhere in the company steering the recommendation toward the expensive answer. When the honest move is the cheap fix, you hear the cheap fix. When the honest move is not spending money at all, a settings change, a warranty claim we can file instead, you hear that too, because the long game in a sixteen-county market where everyone talks is the only game worth playing.
Hill Country weather writes the calendar for this work. Spring arrives with live oak pollen that mats coils and a short, sweet window when every system should get proven before the heat. Summer parks a hundred degrees over the county for weeks and finds every weak component in three counties within about seventy-two hours of the first real wave. Fall is the second proving window, shorter than spring. And winter shows up sideways, forty-degree drops in an afternoon, a hard freeze every few years that tests everything at once. The lake chain adds year-round humidity that inland Texas never deals with, working on coils, drains, and cabinets on its own schedule. Every service in this category gets scheduled, stocked, and staffed around exactly that calendar, because the weather here does not negotiate.
Coverage and the Long Game
All of this work runs across the full sixteen-county map, from home base in Burnet through the Highland Lakes, the Williamson County corridor, Austin, the Killeen and Temple side, and out to the edges at Waco, Boerne, and Fredericksburg. The 24-hour line covers every mile of it, because failures in this category do not check the clock before they happen. And behind the whole catalog sits the maintenance rhythm, the two-visit-a-year habit that catches most of these failures while they are still cheap findings instead of emergency calls.
The Shop Behind the Work
The company behind this category is the same one behind all 147 services: Off Duty Heating and A/C, second-generation, based in Burnet, running about a hundred miles of Central Texas with stocked trucks and honest windows. No commissioned salespeople anywhere in the building, which changes every recommendation you will ever hear from us. Factory credentials where they matter, Mitsubishi Diamond on the ductless side, JB warranty authorization on the service side. And a name that is a working promise: off duty is what the rest of the trade goes at 5 PM. The phone here answers around the clock, every day of the year, including the ones with fireworks and turkeys.
Booking It
When you are ready to book, the process respects your time: the phone gets answered by someone who can actually talk about your system, not a call center reading a script, and plenty of questions get resolved right there at no charge. Scheduled visits arrive inside honest windows with a heads-up call when the truck is en route. Working households can arrange service without taking the day off, keyless access, text updates, photos of the finished work, findings called before any decision-requiring work proceeds. However your household runs, the service fits around it, and the invoice always matches the words said before the work.
Mini Splits Questions
Asked Before Booking
My mini-split is blinking and will not cool. What now?
The blink pattern is a diagnostic code, and the honest first step is reading it rather than clearing it: those codes distinguish sensor faults, communication errors, refrigerant problems, and drain issues, each with a different fix and a different price. Power-cycling sometimes clears the symptom and never the cause. The repair visit reads the code, verifies the actual fault with instruments, and quotes the real fix before touching anything, per the standing practice. Bring the brand and model to the phone call and the diagnosis often starts right there.
Does a mini-split really heat well enough for winter here?
Modern units handle Hill Country winters comfortably, holding strong output well below freezing, which covers the overwhelming share of our cold hours. The genuine deep freeze is the caveat, and for a primary-residence whole-home ductless design we plan for it honestly, cold-climate-rated heads, backup strategy where the situation warrants. For the garage, casita, and addition duty most mini-splits pull here, winter performance is simply a non-issue. The sizing math and the honest conversation happen before any install, and the twelve-year warranty rides along after it.
What does a service call cost for this category?
The visit cost gets stated on the phone before any truck moves, and the work itself gets priced after diagnosis and before repair, out loud, in plain English. No category on this site carries teaser pricing, because printed teaser numbers turn into invoice arguments, and we would rather tell you the truth from the start. Larger projects in this category get written quotes with the scope itemized, financing options get discussed with real numbers when asked, and warranty coverage gets checked before work begins so covered failures cost you a claim instead of a repair.
How fast can you get out for this kind of work?
Depends on where you are and what failed, and the window you hear on the phone will be the honest version of both. Home-county calls routinely land same-day, corridor and lake-town calls ride scheduled weekly routes with same-week the norm, and genuine emergencies jump every queue around the clock. What never happens is a fabricated arrival time to end the phone call: the window stated is the window kept, drive included, per the policy that runs the whole company. Describe the symptom when you call, because it changes the triage, and a real diagnosis often starts right there on the phone.
Do you actually do all of these services, or is this a menu of maybes?
Every service listed on this page is work we actually perform, with its own full page behind the link explaining exactly how we run it. The catalog is 147 services deep because Central Texas systems fail 147 different ways, and a decade in the trade has put our hands on all of them. The trucks stock for the common failures in this category specifically, the specialty work schedules like specialty work should, and when something genuinely sits outside our lane, which is rare, you hear that on the phone instead of after a wasted visit.
