Air Handler Repair, Explained Straight.
The air handler is the half of your system that lives indoors, usually in the attic, doing everything at once: moving the air, holding the cold coil, managing the condensate, hosting the controls. When it fails, the whole house knows immediately. When it merely struggles, the house pays quietly on every bill until someone climbs up and looks.

The Attic Machine That Does Everything
Inside that sheet-metal cabinet lives most of the system’s moving complexity: the blower and its motor, the evaporator coil, the metering device, the primary and emergency drain pans, the float switches, the control board, the filtration, and on heat pumps, the auxiliary heat strips. Central Texas puts this whole assembly in the attic, an environment that hits 130-plus degrees every summer afternoon, which stresses electronics, bakes motor bearings, and turns every service visit into hot, cramped, flashlight work. It is the least pleasant workspace in residential HVAC, and it is where half the system’s failures actually live.
The failure catalog spans everything the cabinet contains. Blowers hum, scream, or die, and airflow with them. Boards fail from heat cycling and power events, producing dead systems or bizarre intermittent behavior. Coils leak and freeze, drains clog and trip floats, strip heat sequencers stick, either never helping or, worse, helping constantly at strip-heat prices. Cabinet issues have their own entries: rusted pans, sweating uninsulated sections raining on ceilings, panels left loose by past visits whistling air and dollars into the attic. Diagnosis in that heat rewards preparation, and ours arrives with the instruments and the common parts already staged.
Every air handler visit ends with the housekeeping that attic units deserve: drains verified flowing, floats tested, panels sealed properly, and the readings recorded, because the next tech in that attic, probably us, should start from data.
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 air handler repair correctly here means doing it for this climate, with parts choices and settings that respect what Central Texas actually does to machinery.
Air Conditioning
Inside-the-Cabinet Failures
What actually breaks in the indoor unit, drawn from a decade of Central Texas attics.
Blower dead or dying
The heartbeat failure: no airflow, no anything. Motors, modules, and capacitors, stocked and swapped with amp draws verified.
Control board faults
Heat-stressed boards fail outright or intermittently. Diagnosed properly, since boards get blamed for many sins they did not commit.
Coil icing or leaking
The cold heart of the cabinet, with its own repair pages. Access and assessment start here in the handler.
Drain system failures
Pans, lines, and floats in the machine that makes gallons daily, above your ceiling. Verified on every single visit.
Strip heat misbehavior
Sequencers and elements that never help, or help constantly. The silent bill-doubler, caught with an amp clamp.
Cabinet leaks and sweat
Air leaks bleeding conditioned air into the attic, uninsulated spots raining condensation. Sealed and corrected properly.
Not sure this is your problem?
Call anyway. We name the likely cause on the phone for free, and if it turns out to be something small you can handle yourself, we say exactly that and save you the visit.
Why Off Duty
Respect for the Worst Room in the House
Attic work in a Texas summer is genuinely punishing, and that reality shapes industry behavior in ways homeowners never see: visits get shortened, inspections get skipped, and access panels get left loose at 128 degrees, because thoroughness up there costs sweat. We staff and schedule for it instead, early slots in brutal months, proper lighting and preparation, and a checklist that does not shrink with the temperature. The alternative is the fleet we regularly inherit: air handlers untouched for a decade because nobody wanted the climb, quietly wasting money the whole time. If yours has not been looked at since installation, that is normal and worth ending.
The air handler is also where whole-system health is most visible: static pressure readings at the cabinet expose duct problems, coil condition tells the filtration story, drain state predicts the next water event, and strip amp draws reveal the silent winter bill-padder. A proper repair visit reads all of it while the panels are off, which is why our air handler calls routinely end with the real list, what needs fixing now, what is drifting, what can wait, ranked honestly with numbers attached.
Every air handler repair 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.
One honest note about timing. Problems in this category rarely improve on their own, and the price of waiting is usually a bigger bill: the weak part takes a healthy one with it, the small leak becomes a stain on a ceiling, the strange noise becomes a seized motor. Calling early is almost always the cheaper version of the same repair, and the phone consult costs nothing: describe what you are seeing and we will tell you honestly whether it can wait.
You will also know exactly who is in your house. This company runs on one standard because it mostly runs on one set of hands: Bryce, second-generation in the trade, with every credential on the about page and every kind of job photographed in the gallery. Small shop, short chain of accountability, no strangers in rotation.
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.
Air Handler Repair Questions
Asked Before We Roll a Truck
The ones the phone line hears most for this service, with the answers given at full length instead of sales-brochure length.
My air handler is making a loud noise. What is it?
Translate by sound. Screeching or grinding: blower motor bearings on their way out, weeks of warning before the silence. Rhythmic thumping: an unbalanced blower wheel, dirt-loaded or damaged. Rattling: loose panels or debris in the cabinet, cheap and quick. Buzzing: electrical, contactors, transformers, or a board, deserving prompt attention. Whistling: air being forced through leaks or a strangled filter. And water sounds mean the drain system wants checking today. Describe the noise on the phone and triage starts immediately; most of these are same-visit fixes with the right parts staged.
Why is my air handler leaking water through the ceiling?
The machine condenses gallons daily, and that water is escaping its intended path: a clogged primary drain backing up the pan, a rusted or cracked pan giving way, a failed float switch that should have shut things down, or an uninsulated cold spot sweating onto sheetrock. First move: cooling off at the thermostat to stop production, then call promptly, this qualifies for urgent handling because the damage bill grows hourly. The repair addresses the actual escape route and then verifies every layer of protection, pans, lines, floats, because water above a ceiling deserves redundancy.
What is that burning smell when my heat comes on?
The first heating morning of the year, a brief dusty-burning smell is usually just summer’s dust cooking off the strip elements, common, and gone within the hour. Persistent, recurring, or electrical-smelling variants are a different story: overheating wiring, a failing blower motor, or strip heat problems, and they deserve the system shut off and a prompt call. The distinction is duration and character, and we will help you make it on the phone at any hour. When in doubt, off and call, heat strips draw serious power and have earned their respect.
Should I repair my old air handler or replace it with the system?
Age-matching drives the honest answer. Air handlers and outdoor units are engineered as pairs, and a handler’s major failures, coil, blower assembly, board cascade, on equipment past ten or twelve years usually argue for the matched replacement conversation rather than serial repairs on a mismatched survivor. Cheap fixes on any age: make them. Major surgery on an aging half of a pair: see both quotes first, because the repair-only path often just schedules the next attic visit. You get the fork priced honestly, five-year math included, and the choice stays yours.
How often should an attic air handler be serviced?
Twice yearly inside the normal maintenance rhythm, spring before cooling and fall before heating, because the cabinet participates in both seasons and its drain system especially needs pre-summer attention. Between visits, the homeowner’s share is the filter, checked monthly in Texas dust reality, and a periodic glance at the emergency pan for standing water, which is the cabinet’s way of requesting a visit. The units that reach fifteen years gracefully are the ones that got that rhythm. The ones that make this page’s repair list usually skipped a decade of it.
