AfterFast, Reliable Furnace Repair Across Austin
Furnace repair in Austin typically costs $150 – $700 and most calls are completed same-day when you call before noon. Our dispatch office coordinates crews from right here in Austin, so we’re familiar with the rural fringe properties off Spicewood Springs Road, the slab-on-grade neighborhoods of North Austin, and the exposed Hill Country lots where wind exposure and propane dependency create repair scenarios you won’t find in Dallas or Houston.
We’re Brandt HVAC, and our name comes from an old word for firebrand – the kind of torch used to carry warmth from one place to another. That history matters to us because furnace repair is fundamentally about restoring heat safely, especially when temperatures drop near zero like they did during Winter Storm Uri. Our phones are answered by a live person 24 hours a day, 7 days a week. Call us at (984) 538-9003 and we’ll tell you exactly who we’re sending, send you their photo and name before they arrive, and show you their Threshold Verified badge at your door.
Why Brandt HVAC Is Austin’s Preferred Furnace Repair Company
We’ve built our reputation in Austin by handling the repair problems other companies miss. The combination of cedar fever season and propane-dependent rural properties here means many furnace calls require verifying that combustion air intakes haven’t clogged with Ashe juniper pollen while also confirming LP orifice sizing – a dual-fuel, two-fuel-type diagnostic that simply doesn’t come up in Dallas or Houston markets.
Our Austin office coordinates scheduling and dispatch locally. That matters when you’re off FM 2222 or in the Pflugerville area and need a technician who understands that your furnace might be running as backup to a heat pump rather than as your primary heat source – a configuration we see constantly since Uri pushed so many homeowners toward dual-fuel retrofits.
Every repair begins with a written price before any work starts. No exceptions. Every repair also carries our 365-Day Done Right Promise: if it fails, we return at no charge. You’ll know your technician’s name and see their face before they ever knock. If someone arrives who you weren’t told to expect, that visit is on us.
Gas Furnace Repair in Austin
Gas Furnace Repair in Austin covers both natural gas systems in the city core and propane conversions on the rural fringe where natural gas lines don’t reach. The job involves diagnosing ignition failures, heat exchanger cracks, gas valve malfunctions, and blower motor issues – but in Austin, it also means checking for cedar pollen clogging combustion intakes and verifying that propane orifices are correctly sized after tank or supplier changes. Most Gas Furnace Repair calls in Austin run $150 – $700, including diagnostic and common parts.
Propane Orifice Sizing and Combustion Safety
On rural Austin properties, we regularly find propane furnaces running rich because the orifice was never resized after a tank swap or supplier change. Rich combustion soots the heat exchanger, wastes fuel, and creates carbon monoxide risk. We clean the exchanger, install the correct orifice for your current propane pressure, and test combustion with a digital analyzer before we leave.
Heat Exchanger Inspection After Hard Run Cycles
Uri-style cold snaps push Austin furnaces harder than they’re designed for. We inspect heat exchangers with cameras and combustion analyzers, not just flashlights. A cracked exchanger means carbon monoxide in your air. If we find one, we show you the image, explain your options, and never pressure a replacement when repair is safe.
Furnace Tune Up in Austin
Furnace Tune Up in Austin is preventive maintenance that catches the problems our climate accelerates – cedar pollen buildup, heat exchanger sooting from propane misconfiguration, and blower strain from undersized ductwork in unconditioned attics that hit 150°F all summer. A Furnace Tune Up runs $80 – $200 and includes written documentation of everything we find, with no upsell pressure because our technicians aren’t paid on commission.
Combustion Air Intake and Flame Sensor Cleaning
December through February, Ashe juniper pollen mats on intake screens and fouls flame sensors. The furnace locks out, you smell gas on restart, and you call thinking it’s an ignition failure. Usually it’s a $150 cleaning, not a $500 part. We check this first because we’ve seen it hundreds of times in Austin.
Dual-Fuel System Coordination Check
Since Uri, many Austin homes run heat pumps with furnace backup. A Tune Up verifies which system is actually doing the work and whether your thermostat’s balance point is set correctly for our electric rates. Wrong settings mean you’re heating with expensive propane when cheap heat pump operation would handle the load.
Trusted Brands We Service in Austin
We repair Rheem, York, Daikin, and Bryant systems daily in Austin, and we stock common parts for these brands at our local dispatch office to avoid multi-day waits. That matters when your furnace fails during a January freeze and every contractor in town is backed up. We also service Carrier, Trane, Lennox, Goodman, and American Standard – the full range of equipment installed in Austin’s 1970s – 1990s housing stock and the production-built subdivisions from the 2010s boom. Our technicians carry the most common ignitors, gas valves, and blower motors on their trucks, and if we need to order something specific, we tell you exactly when it will arrive and what your temporary heating options are.
Common Furnace Repair Problems We See in Austin Homes
- Propane orifice misconfiguration after tank changes. Rural properties around Austin often switch propane suppliers for better pricing, but the new tank’s pressure regulator may differ. The furnace orifice doesn’t match, combustion runs rich, and the heat exchanger soots within a season. We size and replace orifices, then test with a combustion analyzer.
- Cedar pollen lockouts December through February. Ashe juniper pollen from the Hill Country clogs combustion air intakes and coats flame sensors. The furnace locks out, homeowners smell unburned gas, and they assume major failure. Usually it’s a thorough cleaning and intake screen replacement.
- Heat pump backup confusion after Uri retrofits. Many Austin homes now have dual-fuel systems where the furnace runs only below a thermostat-set balance point. Homeowners think their furnace is broken when it’s actually the heat pump that failed, or vice versa. We diagnose the whole system, not just one component.
- Undersized ductwork in unconditioned attics. Austin’s slab-on-grade homes from the 1970s – 1990s have flex duct running through 140°F+ attic space. The duct degrades, leaks develop, and the blower motor works overtime. We measure static pressure and airflow, then show you where your heat is actually going.

These are real Austin market ranges, not teaser rates. What pushes a repair toward the higher end? Heat exchanger replacement, gas valve replacement on a high-efficiency condensing furnace, or blower motor failure in a variable-speed system. What keeps it lower? Ignitor replacement, flame sensor cleaning, or capacitor replacement – the items that fail most often. We give you a written, itemized price before any work starts, and that price doesn’t change unless you ask for additional work. Estimates are free. Call (984) 538-9003.
Austin Energy’s municipally-owned utility structure also means rebate tiers and equipment requirements that differ from Oncor-served Dallas or CPS Energy-served San Antonio. If your repair involves equipment that might qualify for efficiency incentives, we note that in our written estimate so you can make an informed decision.

FAQs About Furnace Repair in Austin
It’s usually both, and in Austin’s propane market it’s often traced to an orifice that wasn’t resized after a tank or supplier change. The furnace is getting fuel at a pressure it wasn’t configured for, so combustion runs incomplete, creates soot, and produces that sharp, unburned-gas smell. We clean the heat exchanger, install the correct orifice for your current propane setup, and verify with a digital combustion analyzer. Call (984) 538-9003 for a free estimate.
Cedar fever season in Austin – December through February, when Ashe juniper pollen peaks – mats on combustion air intake screens and fouls flame sensors. The furnace detects weak flame or poor airflow and locks out as a safety measure. It restarts, fails again, and you get a no-heat call that looks like ignition failure but is actually pollen contamination. We clean the intake, replace the screen if needed, and verify flame signal strength. This pattern is specific to Central Texas and doesn’t occur in Dallas or Houston.
Yes. Some of our most specialized work is on rural properties where natural gas isn’t available and propane is the only heating option. We carry LP conversion kits, orifice sizing tools, and combustion analyzers calibrated for propane. We also understand the dual-fuel configurations common since Uri, where your furnace backs up a heat pump. Call (984) 538-9003 – we’ll confirm your location and dispatch a technician equipped for propane service.
Probably not, if your system was installed or upgraded after 2021. Most post-Uri dual-fuel retrofits in Austin use the heat pump as primary heat and the furnace only below a set balance point, typically around 35 – 40°F. If your furnace is running constantly in mild weather, your heat pump may have failed or your thermostat may be misconfigured. We diagnose the whole system, check refrigerant levels and defrost controls on the heat pump, and verify your balance point against Austin’s electric and propane rates.
Once yearly, ideally in October or November before the first cold snap and before cedar pollen season begins. Austin’s combination of attic heat degradation, pollen exposure, and occasional hard freeze cycles means preventive maintenance catches problems that milder climates wouldn’t create. Our Furnace Tune Up is $80 – $200 and includes a written report of everything found, with no commission-based upsell. Call (984) 538-9003 to schedule.
