Burnet’s Shop, Sunset Valley’s Number.
Sunset Valley is the island city inside South Austin: a few residential streets with generous lots wrapped by a retail district that pays the bills, no city property tax, and homes whose owners chose the enclave deliberately and maintain it that way.

The Island City, Fully Served
Sunset Valley runs one of the metro’s stranger geographies: a small independent city entirely surrounded by Austin, its residential core a few quiet streets of generous lots and established homes, its retail district along Brodie carrying commercial density that most towns ten times its size would envy. The residential stock skews established, ranch homes and custom builds on big lots, many original households who chose the enclave for its independence and stayed decades, and the mechanical work follows: aging systems needing honest repair-versus-replace counsel, replacements engineered rather than swapped, and the maintenance rhythms that long-tenure owners tend to keep faithfully.
The commercial side is the city’s engine: the retail corridors along Brodie and Ernest Robles carry big-box, restaurant, and service businesses whose systems run commercial stakes daily, rooftop units on maintenance rhythms, restaurant kitchens with their heat-and-cold-chain realities, and the emergency response that revenue interruptions deserve. Serving both halves of the island city runs on the same routes, windows quoted with honest South Austin traffic math, and the enclave’s scale means the residential file is intimate: a city of a few hundred households where service reputations are common knowledge, which is exactly the market a straight-dealing shop wants. The greenbelt edges and the famously low tax bill keep the residential streets stable, turnover rare, and the maintenance relationships here tend to run long, the same households, the same systems, the same honest file, year over year.
The range goes from a twenty-minute part swap to a multi-day changeout. Small end: a flame sensor cleaned, a float switch reset, a thermostat wired right. Middle: coil work, leak repair, blower motors, the bulk of what repair calls turn out to be. Big end: a full system with a load calculation behind it, permits where the county wants them, and commissioning numbers recorded at the end of the install. Everything in between is on the list.
New equipment bolted to old ductwork is the most common way a good system disappoints its owner. A furnace and coil move a specific amount of air to do what the label says, and if the duct system cannot pass that air, the label is fiction. So before anybody picks a model number, the ducts get evaluated: static pressure measured across the air handler, return size compared against what the new airflow needs, the trunk and branch layout checked, the accessible runs looked at for crushes and disconnections. Plenty of changeouts out here need a bigger return or a reworked plenum more than they need a higher efficiency rating. That gets quoted as part of the job rather than discovered afterward, because the alternative is a homeowner who paid for high-end equipment and got a noisy blower, a starved coil, and the same hot back bedroom. The install process starts there for a reason.
The Travis County Context
What Travis County Systems Face
Travis County HVAC runs three climates in one county: the urban core’s heat-island load stacking onto Austin’s older housing stock, character homes with retrofit constraints and additions layered across decades; the hill country west side, where high glass, hillside exposure, and premium builds demand design-grade thinking; and the Lake Travis chain, living the same waterfront humidity and part-time-occupancy reality as our home lakes. The county’s traffic is its own weather system, which is why our Travis scheduling runs clustered routes and honest windows rather than optimistic ones, and why the emergency line quotes the real drive at the hour you call. The 183 and 71 approaches, the 620 loop, and the lake roads are known territory, and the county’s range, downtown bungalow to Lakeway glass, is the file’s widest chapter.
Houses near the Highland Lakes carry more moisture than the ones on higher ground, and the equipment feels it. Coils stay wetter, drains load faster, and a system sized purely for temperature can hit its thermostat setting while the house still feels clammy. Sizing and runtime matter more than raw tonnage on lake-adjacent property, and sometimes the honest fix is dehumidification rather than more cooling.
A frozen coil looks like the strangest failure in the trade and it is usually the simplest. Somebody in Sunset Valley calls because the air conditioner is blowing warm, goes and looks, and finds a block of ice on the indoor coil or frost creeping down the copper. Ice means the coil got colder than it should have, and that happens when not enough warm house air is moving across it. So the hunt is for airflow: a filter nobody changed since spring, a return grille blocked by furniture, a blower wheel packed with dust, a crushed flex duct in the attic, a closed-off damper. Low refrigerant charge freezes a coil too, which is why the charge gets weighed rather than guessed. The first instruction over the phone is always to shut the cooling off and run the fan alone so the ice melts, because nobody can diagnose a coil they cannot see.

Why Sunset Valley Calls Burnet
The Off Duty Standard, Delivered Here
Install days run on a different sequence than repairs. Load calculation first so the equipment is sized to the house instead of to whatever came out of it. Ductwork assessed, because new equipment on bad duct work disappoints everybody. Old system recovered and hauled off, line set evacuated to a real vacuum, new unit set, brazed, charged and commissioned with the numbers recorded. Permits where the county wants them. Book it through (512) 925-3090.
Read the invoice against what you were told on the driveway. The words should match, line for line, with no fuel charge that appeared out of nowhere, no diagnostic fee that got counted twice, no shop supplies rounding. If a number on paper surprises you, we wrote it wrong, and we will fix it. That has been the standard since the shop opened.
A system can be losing capacity for years without anybody calling it broken, and the only way to know is to measure the same things every season and compare. Refrigerant charge is the big one: a slow leak means a charge that drops a little each year, and a system running light cools acceptably in May and falls behind in August, which most homeowners chalk up to the system getting old. Weighing and verifying the charge annually catches the leak while the repair is still small. Temperature split across the coil, static pressure across the blower, and amp draws do the same job for airflow and mechanical wear. Put three years of those numbers side by side and the trend tells you what the system is going to do next summer. That record is also what makes a warranty claim go smoothly, and it is worth something real when the house sells.

Sunset Valley Questions
Sunset Valley Questions, Straight Answers
Our house has been here since the seventies. Time to replace the system?
The instruments decide, not the calendar: established homes here often carry systems maintained well enough to serve honestly past normal expectations, and the assessment reads actual condition, compressor health, refrigerant era, repair trajectory, efficiency gap, then lays the math out plainly with your timeline in it. When replacement earns itself, the project runs as engineering, fresh load calculation for a house that has likely gained insulation and windows since original construction, duct evaluation, right-sized equipment, and unhurried commissioning. When it does not, honest repair keeps serving. Either way the counsel serves the house.
Do you service the businesses in the retail district?
Full commercial strength: rooftop units and split systems across the retail corridors, restaurant work with kitchen-heat balance and walk-in stakes, maintenance agreements scheduled around business hours, and emergency triage that treats revenue interruption as the event it is. The district’s density makes service routes efficient, standing accounts anchor regular rhythms, and the quoting runs the same straight-number policy as everything else on the map. A commercial failure costs by the hour, and the response standard respects the math.
How do you handle scheduling into South Austin?
With honest traffic arithmetic: Sunset Valley rides clustered Travis routes, windows get quoted with real drive-and-traffic math rather than optimism, arrival communication runs direct, and scheduled work batches efficiently with the surrounding territory. Emergencies get truthful around-the-clock windows, hours stated as hours per the standing policy. The enclave’s compact geography actually helps, one exit, a few streets, known addresses, and the honest window kept remains the whole promise, at this address like every other.
Do you work on commercial equipment too?
Yes, and the same phone number covers it around the clock. Rooftop units, split systems in offices and shops, walk-in coolers and freezers, and refrigeration in restaurants and stores. Commercial failures get triaged with the loss clock in mind, because warming product and an empty dining room both cost money by the hour. We also say plainly whether a fix is permanent or a hold until a part arrives, since a business surprised twice is worse than a business told the truth once.
What should I do before I call about a no-cool?
Four things, and they take two minutes. Check that the thermostat is set to cool and actually calling, with fresh batteries if it takes them. Look at the filter, because a loaded one causes more no-cool calls than any single part. Check the breaker for the indoor and outdoor units and reset it once, but only once. Then look at the outdoor unit to see whether the fan is turning. Tell us what you found and the diagnosis starts ahead of the truck.
