HRV Services, Explained Straight.
The HRVs running around Central Texas mostly arrived by builder spec or northern habit, and they age like all balanced ventilators: filters loading, cores fouling, flows drifting, controls failing quietly. Service keeps an existing HRV delivering its design, and the honest assessment answers the standing local question, whether the heat-only machine still serves the house, or its next core should transfer moisture too.

Existing HRVs, Kept Working, Assessed Honestly
The service physiology matches the balanced-ventilation family: both filter streams changed on schedules the site’s pollen and dust actually set, the sensible core extracted and washed, HRV plate cores tolerate more robust cleaning than their enthalpy cousins, one of the format’s ownership conveniences, condensate paths cleared and tested, since heat-only cores condense meaningfully in our humid months and their drains carry real duty, flows measured and rebalanced to design match, the item that keeps the machine a ventilator rather than a pressurizer, controls exercised, and terminations cleared of the outdoor census. Repairs follow findings, motors, actuators, boards, dampers, all serviceable economics on sound cabinets, quoted plainly.
The Texas-specific layer is the assessment this page owes every HRV owner: the heat-only core imports summer humidity that an enthalpy core would have rejected at the exchange, a daily tax in our climate that the unit’s northern designers never priced, and the honest arithmetic reads your machine’s duty, the house’s dehumidification load, and the core-replacement moment, many platforms accept enthalpy cores in the same cabinet, to answer whether your HRV should stay an HRV. Some should, the workshop and high-internal-moisture applications that wanted heat-only on purpose, and the whole-home units serving ordinary houses usually deserve the conversion conversation at their next core cycle, numbers shown, upgrade priced against the humidity it would stop importing.
Either verdict gets full service craft meanwhile, because a maintained HRV beats a neglected anything, and the file tracks the machine toward whichever future the arithmetic supports.
Local conditions shape this work more than most homeowners expect. Our summers stack week after week of hundred-degree afternoons, which means long compressor runtimes, drain lines moving gallons of condensate a day, and electrical components living near their limits from June through September. Lake humidity keeps the corrosion clock running even in mild months, and spring pollen packs filters fast enough to choke airflow in weeks. A tech who works this exact hundred miles every day builds all of that into the HRV service call: what to check first, which parts fail early here, and which settings survive a Texas cooling season instead of merely a laboratory one.

Why Off Duty
Repair, Convert, or Replace
The three-way fork gets refereed with numbers: repair serves the sound-cabinet fleet’s ordinary failures, motors, actuators, controls, at honest cost; conversion, an enthalpy core in the existing cabinet where the platform supports it, upgrades the whole-home units that never should have been heat-only here, priced against the humidity tax it retires, frequently the arithmetic winner at core-replacement time; and full replacement belongs to aged cabinets, dead parts channels, and the units whose duty outgrew them, with the current ERV generation’s performance quoted alongside. The house’s application decides the frame, workshop heat-only cases exempt from the conversion push entirely, and the verdict arrives with its evidence, per the house habit.
Orphaned HRVs join the fleet the same way their ERV cousins do, builder-installed, never serviced, discovered humming in an attic by our assessment, and the revival visit gives them the baseline treatment: identified, serviced, measured, filed, and folded into the rhythm, with the enthalpy question answered while the panels are open. If your tight-built house ventilates through a machine nobody has touched since closing, the first service usually pays for itself in restored recovery alone, and the Texas-fit assessment rides along free, which around here is where the real money usually hides.
Here is how the visit goes. A call to (512) 925-3090 reaches a real tech, not a call center, at any hour. On site, the diagnosis runs on instruments until the cause is certain, and then everything gets laid out in plain English: what failed, what fixes it, and exactly what it costs, before work begins. When the HRV service work is done, it gets verified under load instead of switched on and waved at. If the pattern sounds simple, it is. It is also rare enough in this trade that people write reviews about it.
Money talk, handled the Burnet way: we say the price before the work, every time. The trip cost comes over the phone before we roll, the repair quote comes after diagnosis and before a single part goes in, and if the smart move is to not spend money at all, you will hear that too. Fair pricing shows up in every review we have because it is policy, not luck.
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.
This service runs wherever our trucks do: home base in Burnet, the Highland Lakes from Granite Shoals to Buchanan Dam, down the corridor to Round Rock and Austin, north to Killeen and Temple, and out to the sixteen-county edge at Waco, Boerne, and Fredericksburg. The whole map lives on the service areas page, with drive-time honesty built into every window we quote.

The Standard
How This Work Gets Done Here
Every trade job carries an invisible line item: the standard it was done to. On HRV service work, ours reads like this. The diagnosis is proven with instruments, because guessing is expensive and it is your money on the table. The parts that go in are parts we would put in our own house, matched to spec instead of whatever was cheapest on the shelf. The workmanship follows the manufacturer’s book and the Texas code book both, because shortcuts hide for exactly one season and then bill you with interest.
When the work is finished, it gets tested the way it will actually be used: under load, at temperature, with the readings written down. Then the area gets left the way we found it or cleaner, the old parts get shown to you on request, and the invoice matches the number you already heard. If anything acts up afterward, you call the same number and the same person answers. That is the entire warranty conversation most customers ever need, and it is why the reviews keep saying the same three things: honest, fair, showed up.
HRV Services 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.
What service does an HRV need in this climate?
The family physiology, filters on both streams at site-honest intervals, the plate core washed annually, flows rebalanced to design, controls verified, plus the humid-climate emphasis the northern manuals underweight: condensate paths cleared and proven before each cooling season, since heat-only cores condense hard against Texas moisture, and cabinet corrosion watched on the same schedule. Continuous duty ages the fans on runtime, so amp draws get read annually too. It folds into the standard maintenance rhythm, and the serviced fleet’s pattern holds here as everywhere: rated recovery for years, versus the quiet drift to expensive-fan status that neglect writes by default.
Should my HRV be converted to an ERV?
The standing Texas question, answered by application and arithmetic: whole-home HRVs serving ordinary houses import summer humidity an enthalpy core would reject, a daily dehumidification tax in this climate, and where your platform accepts an enthalpy core swap, the conversion prices against that tax honestly, frequently winning at the natural core-replacement moment; the legitimate heat-only applications, workshops, high-internal-moisture spaces that want moisture exhausted, keep their HRVs on purpose and the assessment says so. The referee work is reading your machine’s duty and the house’s moisture ledger, numbers shown, and the answer is genuinely split across the fleet, which is exactly why it gets asked per-unit rather than assumed.
Why is there so much water draining from my HRV in summer?
Physics doing its job in the wrong climate frame: warm humid outdoor air crossing the cool exhaust-side plates condenses, heavily in Texas summers, and the heat-only core sheds that moisture into its drain rather than transferring it back out the way an enthalpy core would, so vigorous summer condensate is the HRV’s signature here, normal for the machine, informative about the fit. The service angle is drain integrity, that water flowing freely and terminating properly, verified before each cooling season, and the strategic angle is the conversion question above, since the drain’s vigor is literally measuring the humidity your ventilation imports. The machine is fine; the assessment is whether it is the right machine.
Can you fix an HRV the builder installed years ago?
The orphan revival is routine: identified by model, filters sourced and changed, the plate core washed back to open passages, flows measured against nameplate and rebalanced, controls and defrost logic exercised, condensate proven, and the baseline file started, after which the machine joins the rhythm like any equipment here. Repairs surface honestly where the years left them, motors, actuators, boards, priced plainly, and the Texas-fit assessment answers the enthalpy question while everything is open. Builder-fleet units respond well; the platforms are robust, and their neglect is usually pure obscurity rather than abuse. Bring nothing but the house; the machine tells us the rest.
Is it worth maintaining an HRV, or should I just replace it with an ERV now?
Maintenance wins the immediate math almost always: a serviced HRV delivers real recovery today at service-visit cost, while replacement is equipment-scale money best timed to genuine triggers, core aging, major component failure, or the natural upgrade moments, and the conversion path, enthalpy core into the existing cabinet where supported, often splits the difference at core-cycle time, upgrading the climate fit without the full replacement spend. The assessment sequences it honestly for your unit: keep it healthy now, name its conversion or replacement trigger, and let the arithmetic call the timing rather than either impatience or neglect. Meanwhile the maintained machine keeps ventilating, which was always the point.
