When your furnace quits on a January night in Austin, you don’t need a call center or a maybe-sometime-tomorrow window. You need someone who picks up the phone, tells you what the fix will cost before touching a tool, and stands behind the work for a full year. That’s the job. Cold Harbour Heating and Air Austin has handled our Furnace Repair in Austin since 2003, and every repair from Pflugerville to Shady Hollow carries the 365-Day Done Right Promise in writing. Call (361) 204-1605 and a live person answers, any hour, any day.
Victor Mancini leads our Austin team with a simple rule: the price you sign is the price you pay, the guarantee is on paper, and the technician leaves your home cleaner than they found it. If a repair fails inside 365 days, we return and do it again at no charge. That’s not a promotional line. It’s what we write down before we leave.
Furnace Maintenance
Furnace Maintenance means keeping the system clean, safe, and efficient before a cold snap forces the issue. In Austin, where furnaces sit idle for long stretches and then run hard during sudden freezes, a neglected unit tends to fail exactly when you need it most. Cold Harbour Heating and Air Austin performs a full maintenance visit that includes checking the heat exchanger for cracks, testing the igniter, measuring gas pressure, and verifying the carbon monoxide reading is zero. A maintenance visit on a standard furnace runs $80 – $200 depending on system age and condition.
What We Check and Test
We test every safety switch, inspect the burners for rust or debris, and measure the temperature rise across your heat exchanger. A low rise often means a dirty blower wheel; a high rise can point to restricted airflow. We also check the flame sensor and clean it when needed, because a fouled sensor is the top cause of short cycling we see in Cedar Park and Wells Branch.
How Often Austin Furnaces Need It
Once a year is the right cadence for most homes in Austin, ideally before the first real cold front in late November or early December. If your furnace is older than 15 years or you have pets, twice a year catches filter and airflow problems earlier. Maintenance also keeps manufacturer warranties valid on newer units, which matters when a part fails under coverage.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair covers a system that both heats and cools by moving heat instead of burning fuel. When an Austin heat pump stops heating, the cause is usually a failed reversing valve, low refrigerant, a locked condenser fan, or a defrost control board that no longer clears ice in cold, damp weather. Cold Harbour Heating and Air Austin diagnoses the actual fault before pricing the fix, and heat pump repairs in Austin typically fall between $150 and $700 with everything in writing first.
Common Heat Pump Failures We See in Austin
The defrost sensor fails quietly, and many homeowners first notice the outdoor unit encased in frost. A compressor that’s running but not heating often means low charge or a refrigerant leak that must be found and sealed before recharging. We bring leak detection equipment and temperature probes on every call so we’re not guessing with your money.
When Repair Makes More Sense Than Replacement
If the heat pump is under 10 years old and the compressor isn’t damaged, repair nearly always wins. A capacitor replacement or fan motor fix costs a fraction of a replacement and extends the system’s useful life. Victor’s team will tell you plainly when a repair would be throwing good money at a dying unit, and we’ll put that in writing too.
Heating Repair
Heating Repair is the broad service that covers any heating system in your home: furnaces, heat pumps, boilers, and ductless units. If the house is cold and the equipment won’t cooperate, the first step is a proper diagnosis rather than a parts cannon fired at the problem. Cold Harbour Heating and Air Austin sends background-checked, uniformed technicians who test electrically before replacing anything, then hand you a written price. Heating repair in Austin runs $150 – $700 for most failures, and the price is fixed before the first tool comes out.
Diagnostics Before Dollars
We test thermocouples, pressure switches, circuit boards, and capacitors with meters, not guesswork. On gas systems, we confirm the venting is drafting correctly and the limit switches are doing their job. That protects both the equipment and the people inside the house.
The Written Guarantee on Every Job
Every heating repair from Cold Harbour includes the 365-Day Done Right Promise. If the same fault returns within a year, we come back and make it right at no charge. That’s a written guarantee, not a handshake, and it travels with the repair record on file.
Boiler Repair
Boiler Repair covers hydronic heating systems that circulate hot water through radiators, baseboards, or in-floor loops. Boilers show up in older Central Austin homes and many renovated bungalows around Hyde Park and Travis Heights. Cold Harbour Heating and Air Austin diagnoses boiler faults on-site, from failing circulator pumps to expansion tanks that can no longer absorb pressure swings. Most boiler repairs in Austin come in between $150 and $700 depending on the failed component.
Circulator Pumps and Pressure Problems
A boiler that fires but won’t move heat usually has a failing circulator pump or a seized zone valve. We check voltage to the pump, feel for flow on the return line, and confirm the aquastat is calling for heat correctly. A waterlogged expansion tank will make the pressure gauge spike, and that’s a straightforward swap with the system drained safely.
Older Boiler Systems in Austin Homes
Many of Austin’s 1920s through 1950s homes still run their original cast-iron radiators, often with newer boilers piped in. We’re comfortable working around old plumbing and new controls alike. If a part is discontinued, we’ll find a compatible replacement rather than selling you a whole new system you don’t need.
Gas Furnace Repair
Gas Furnace Repair addresses furnaces that burn natural gas or propane to heat air. If the burners won’t light, the flame keeps tripping the limit switch, or the unit lights then cuts out in under a minute, the problem is usually the igniter, flame sensor, gas valve, or a cracked heat exchanger. Cold Harbour Heating and Air Austin repairs all of it, and gas furnace repairs in Austin typically range from $150 to $700. The written price lands in your hand before we open a panel.
Igniter and Flame Sensor Work
The hot surface igniter glows, the gas valve opens, the flame sensor confirms the burn. If that sensor is coated with carbon, the board shuts the gas off almost immediately. We see this constantly in Austin homes with shedding pets. A replacement igniter or sensor job is usually on the lower end of the range and takes under an hour.
Heat Exchanger Safety Checks
A cracked heat exchanger can leak carbon monoxide into the home. On every gas furnace repair, we inspect the heat exchanger and run a CO test with a combustion analyzer. If we find a crack, we’ll show you the photos and explain whether a replacement part or a new furnace is the safer value. We won’t clear a furnace with a compromised exchanger back into service, period.
Furnace Tune Up
Furnace Tune Up is the annual service that keeps a gas or electric furnace running safely and efficiently through the Austin winter. A tune-up tightens the loose ends that become mid-season breakdowns: dirty burners, weak capacitors, low blower airflow. Cold Harbour Heating and Air Austin charges $80 – $200 for a tune-up, and it includes a written report with photos showing exactly what we found and what we adjusted.
What’s Included in the Visit
We clean the burners, inspect the heat exchanger, test the igniter and flame sensor, check gas pressure, and measure the blower motor’s amp draw against its factory rating. We replace standard 1-inch filters if you have one on hand, and we’ll mark the date and the readings on the service log.
Why a Tune-Up Pays for Itself
A furnace running with a dirty blower wheel can use more electricity than the gas it burns. The tune-up brings the system back toward factory airflow and combustion numbers. Many Austin homeowners book a tune-up in November and skip the January emergency call entirely.
Emergency Furnace Repair
Emergency Furnace Repair means you call at 9 p.m. or 6 a.m. and a human being answers, because a cold house with no heat is a health risk and we treat it that way. Cold Harbour Heating and Air Austin answers the phone live 24 hours a day, 7 days a week, and dispatches from our Austin location without an after-hours runaround. Emergency repairs run the same $150 – $700 range, with no overtime surcharge stacked onto the bill.
What Counts as an Emergency
No heat during freezing weather, the smell of gas, or a furnace that won’t shut off are all emergency calls. A CO detector that has gone off is also immediate. We make these the priority, and if you smell gas, leave the house first and call your gas utility before you call us.
How We Get There Fast
Our dispatch keeps a rolling schedule of available technicians across the Austin metro, including our Furnace Repair in Round Rock, Pflugerville, and Buda. When you call after hours, you speak to a dispatcher, not a machine. We set a firm arrival window and then meet it.
Brands We Service
Our technicians are trained on nine major residential brands, and York is one we see regularly in older Austin neighborhoods where the original builder installed them in the early 2000s. We stock common York ignition parts and know the control board failures that tend to appear after a decade of use.
Daikin and Bryant units also roll through our schedule weekly. Daikin’s variable-speed furnaces need a tech who reads the service manual instead of guessing at error codes, and we do. Bryant’s two-stage gas valves rarely fail all at once; they degrade, and we catch the symptoms before they strand you. Whether you have a York, a Daikin, a Bryant, or any other make, we can help. American Standard systems are in our service rotation too, and our parts suppliers carry their OEM components across the Austin area.

- The burners ignite and immediately shut off. This is usually a dirty flame sensor or a failing control board. Left unchecked, the constant cycling wears out the igniter and can lead to a no-heat morning at the worst time.
- The blower runs but the air coming out is lukewarm at best. That points to a limit switch opening early, a clogged filter, or a burner that’s not running at full capacity. The furnace is working harder than it should and heating the house slower than it could.
- You smell gas near the furnace or vents. Shut the gas valve at the furnace if you can reach it safely, leave the house, and call your gas utility first. Then call us. A gas odor is never normal on a modern furnace.
- The furnace makes a banging or rumbling sound when the burners fire. This can mean delayed ignition or a heat exchanger expanding irregularly. Both are problems that get worse and more expensive the longer they run.
- Your utility bill jumped without a matching cold snap. A furnace losing efficiency through a dirty blower, failing capacitor, or misadjusted gas valve will draw more power to move less heat. We measure the difference and tell you what’s happening.
Our Process, Step by Step

The technician arrives in uniform and introduces themselves. Background-checked, with the truck stocked for furnace, heat pump, and gas work. They’ll ask what you’ve noticed, not to sell, but to listen for the pattern behind the failure.
- 3
Diagnostics run before pricing is discussed. We test gas pressure, electrical draw, igniter resistance, and combustion readings with a digital analyzer. We show you the findings and explain the plain-English version of every trade term.
- 4
You get a written price before any work begins. The quote is fixed and itemized. If the scope changes, we stop and bring you a new written number before moving forward. No surprises at the door.
- 5
We complete the repair, test the full system, and hand you the written 365-Day Done Right Promise. The job site is left clean, the furnace is confirmed to run through a full cycle, and the guarantee is on paper, not implied.
How Much Does Furnace Repair Cost in Austin?
In Austin, most furnace repairs fall between $150 and $700, with the spread driven by the part that actually failed. An igniter replacement on a standard gas furnace typically runs $150 – $280. A flame sensor cleaning or replacement lands in the $120 – $220 range. A control board replacement is the bigger-ticket item, usually $400 – $650 on common brands. A blower motor or inducer motor job commonly lands between $350 and $650 depending on the motor’s horsepower and the system’s age.
What affects the price: the part’s cost from the manufacturer or a local Austin supply house, the age of the system (older parts can mean a longer procurement time), and whether the failure damaged anything downstream. We carry the most common ignition and electrical components on the truck, which keeps labor hours down and gets the heat back on sooner.
How to avoid overpaying: ask for a written price before work starts, and ask whether the part is OEM or aftermarket. Every Cold Harbour quote lists that. A free estimate is exactly that with us: we charge nothing to diagnose a furnace in Austin and put the price in writing. You’re not obligated simply because we showed up.
