Furnace repair in Austin typically costs between $150 and $700 depending on what’s failed, with most common fixes like ignitor replacement or flame sensor cleaning landing in the $150 – $350 range. We get furnaces running again across Austin the same day you call in most cases, because winter cold snaps here hit hard and fast. If your heat is out in Hyde Park, Travis Heights, or up in the Arboretum area, call (361) 326-1553 and you’ll reach a live person who can dispatch a technician to your Austin home right away.
What makes local expertise matter in Austin is simple: the housing stock here is not uniform. A furnace in a 1950s pier-and-beam bungalow off Burnet Road behaves differently than one in a tight, code-strict build in Mueller. Our techs know the difference, and they show up ready for either one.

Austin homeowners call us because they want to know exactly who is walking through their door. Before every visit, we send you the technician’s name and photo.

If anyone shows up who you were not told to expect, that visit is on us and we make it right.
Devin Marlowe leads our Austin team, and he’s built the operation around a simple rule: written price before any work starts. No exceptions. You see the number, you agree to it, then the work begins. That applies whether we’re replacing a blower motor in Cedar Park or diagnosing a gas valve in Bastrop.

Gas Furnace Repair in Austin
Gas Furnace Repair in Austin is the bulk of our winter service work, and the most common problems we see are failed ignitors, dirty flame sensors, and cracked heat exchangers. A homeowner usually needs us when the furnace is blowing cold air, short-cycling, or refusing to fire at all. In Austin, those calls spike during the first hard freeze of the season, when furnaces that sat idle through a long mild fall finally get asked to work.
Most gas furnace repairs in Austin run $150 – $700, with the difference driven by the part that failed and the age of the unit. An ignitor replacement usually lands between $150 and $300 parts and labor included. A blower motor or gas valve repair pushes toward the higher end. Every repair includes a written guarantee, and if it fails within the guarantee period, we return at no charge under the 365-Day Done Right Promise.
Ignitor and Flame Sensor Work
When a gas furnace won’t fire, the ignitor is often the culprit. This is a small ceramic element that glows hot enough to light the gas. In Austin’s older homes, we also see flame sensors so coated with carbon that the furnace thinks the flame never lit, so it shuts down as a safety measure. Both fixes are straightforward and usually completed in a single visit.
Gas Valve and Safety Circuit Repairs
A failing gas valve can cause a furnace to either not fire at all or fire intermittently, which is maddening when the temperature swings from 70 to 25 in a single Austin winter day. Because gas work carries real risk, our technicians check the valve operation, test for leaks at every fitting, and verify the safety circuit before and after the repair. We recommend a licensed professional for any gas-related furnace work, and that’s exactly who we send.
Furnace Tune Up in Austin
Furnace Tune Up in Austin is the best money you can spend before winter actually arrives, and we recommend it every fall. A tune-up is a preventive visit where a technician cleans the burner assembly, checks gas pressure, inspects the heat exchanger for cracks, tests the safety controls, and measures airflow. In Austin, where furnaces sit unused for many months each year, dust and insect debris accumulate in the burners and can cause ignition failures on the first cold night.
Our tune-up in Austin is priced at a flat $80 – $200. You get a written report of what we found, what we cleaned, and what might need attention before the next cold snap. Our technicians are not paid on what they sell, so the report tells you what’s true, not what’s convenient for us.
Heat Exchanger Inspection
The heat exchanger is the metal chamber that separates combustion gases from the air you breathe. A crack in this component is a carbon monoxide risk and must be addressed immediately. During every Austin tune-up, we inspect the heat exchanger for cracks, rust, and stress marks, and we show you photos if we find anything concerning.
Airflow and Duct Condition Check
Furnace performance depends on airflow, and airflow in Austin’s older homes is often compromised by leaky original ductwork. During a tune-up, we check static pressure, listen for whistling returns, and flag duct leaks that are making the furnace work harder than it should. In pier-and-beam homes around Travis Heights and Hyde Park, we also check the return plenum under the house.
Trusted Brands We Service in Austin
Our Austin technicians repair furnaces from every major residential brand, and we see a lot of York, Daikin, and Bryant units across the city. American Standard systems show up often in newer builds around Mueller and the Domain. Because we work on all of these regularly, we stock common parts locally in Austin, which means faster turnaround when a cold snap hits and everyone’s furnace is failing at once. We don’t push one brand over another. We repair the unit you already have and tell you honestly if repair still makes sense.

AfterCommon Furnace Repair Problems We See in Austin Homes
- Leaky galvanized ductwork and undersized returns in 1950s – 1970s bungalows. Central Austin homes from the post-war building boom often have original ducts that leak anywhere from 20 to 40 percent of the heated air into attics and crawlspaces. Low airflow causes the furnace to overheat, trip the limit switch, and shut down during the coldest nights just when you need it most.
- Sagging pier-and-beam foundations separating the return air plenum. In neighborhoods like Travis Heights and Hyde Park, the ground shifts and settles over decades. That movement can pull the return plenum apart under the house, which then draws humid crawlspace air into the furnace. This causes rust, combustion problems, and a persistent musty smell in the house.
- Outdated electrical panels struggling with modern blower motors. Many older central-city homes still run on panels from the 1960s and 1970s. A modern furnace blower draws more current than the panel or breaker was sized for, leading to nuisance trips or a furnace that won’t start at all when temperatures drop overnight.
- Single-zone systems and unbalanced floor plans. Austin’s older bungalows were often built with one central system and no thought given to how the sun hits the west-facing rooms. The result is one bedroom freezing while the living room is comfortable, which drives people to crank the thermostat and overwork the furnace.

FAQs About Furnace Repair in Austin
A limit switch trips when the furnace gets too hot, and in older Austin bungalows the cause is almost always low airflow from leaky original ductwork or an undersized return. The furnace heats up, can’t move enough air through the ducts, and shuts itself down as a safety measure. We fix this by sealing the ducts, enlarging the return if needed, and verifying airflow with a static pressure test. Call (361) 326-1553 for a diagnosis and written quote.
Yes, a sagging pier-and-beam foundation can affect your furnace’s performance. As the floor settles, the return air plenum underneath the house can pull apart at the seams, which lets humid crawlspace air into the furnace. That humidity rusts the heat exchanger, reduces combustion efficiency, and makes the system work harder. In Austin’s central neighborhoods where pier-and-beam homes are common, we check the plenum on almost every repair visit.
A load calculation measures your home’s actual heating and cooling needs based on square footage, insulation, window orientation, and even how much sun hits the west side of the house. In Austin, where summers are brutal and winters bite suddenly, a like-for-like swap often leaves an older home with an oversized or undersized furnace. That leads to short-cycling, uneven temperatures, and higher bills. We perform a load calculation on every replacement, and it’s part of the written quote.
An outdated electrical panel can prevent a modern furnace from running reliably. Newer blower motors draw more startup current than 1960s-era panels were designed to handle, which causes breakers to trip and furnaces to fail on the coldest nights. Before we install a new furnace in an older Austin home, we check the panel and the circuit feeding the furnace, and we tell you in writing if an electrical upgrade is required. Call (361) 326-1553 to have a technician assess your panel during a furnace visit.
Yes, cast-iron floor registers in hardwood floors affect furnace performance, and not always in a bad way. They’re durable and they move a lot of air, but they also let debris fall into the ducts and they can become obstructed by rugs or furniture. In a 1960s Travis Heights home, we often find decades of dust and pet hair packed into the register boots, cutting off airflow to the room. Cleaning and reseating these registers is a small fix that makes a real difference in how evenly the house heats.
In central Austin neighborhoods like Hyde Park and Travis Heights, many homes still have original 1960s-era cast-iron floor registers embedded in hardwood floors over sagging pier-and-beam foundations. Furnace repairs here often start with resealing the return air plenum under the house to stop crawlspace humidity from being pulled into the system. At a 1950s pier-and-beam bungalow in Travis Heights, our tech found a 40-year-old Carrier gas furnace with a cracked heat exchanger and an undersized return plenum that had separated under the sagging floor. We sealed the plenum with mastic and replaced the furnace with a properly sized unit after a load calculation, then verified static pressure and thermostat calibration to keep the single-zone system from short-cycling.
If your furnace is struggling in Austin, call (361) 326-1553. A live person answers, and we’ll schedule a technician to your Austin home with a written price before any work begins.
