AfterFurnace Repair in Austin, TX
Furnace repair in Austin typically costs between $150 and $650 depending on the part that failed, with most common fixes like igniter replacements and flame sensor cleanings landing on the lower end of that range. Cold Harbour Heating and Air Austin fixes furnaces across the city, from Allandale to Circle C, and every repair comes with a written 365-day guarantee before our technician leaves your driveway. If you’ve noticed weak heat, a furnace that short-cycles, or a system that won’t kick on at all, call us at (361) 204-1605 and a live person answers, day or night.
We’re part of the Heating & Furnace in Austin side of our business, which means furnace repair isn’t a side gig for us. It’s core work, and it follows the same four written promises our parent company built its name on: a price before we start, a firm arrival window, a clean job site, and a guarantee that brings us back for free if the repair fails within a year. Victor Mancini has run this shop since 2003, and the standards haven’t softened since.
When You Need Furnace Repair
Furnaces rarely fail without warning. In Austin’s mild winters, the signs can be subtle because the system isn’t running constantly, but they’re still there. Here’s what we see most often in homes from Round Rock down to Buda:
- The furnace runs but blows cold or lukewarm air. This is usually a failed igniter, a tripped limit switch, or a heat exchanger that’s not getting hot enough. If your vents are pushing air that feels barely warmer than room temperature, the furnace is working but not heating.
- The furnace short-cycles. It kicks on for three or four minutes, shuts off, then fires again a few minutes later. In Austin homes built in the 1980s and 90s around the Arboretum area, this often traces to a dirty flame sensor or an overheating limit switch.
- The blower runs constantly, even when the heat is off. A stuck relay or a failing limit switch keeps the fan spinning. It wastes electricity and wears out the blower motor faster than it should.
- You smell something burning when the furnace first fires up. A dusty smell in the first few minutes of the season is normal. A metallic or acrid smell that doesn’t go away is not, and it’s worth a call.
- The furnace makes a loud boom when it ignites. That’s delayed ignition, and it happens when gas builds up before the igniter catches. In a sealed combustion chamber, that’s a small explosion every time the furnace starts. It’s a safety issue, not a noise complaint.
- Your gas bill spikes without explanation. A furnace that’s losing efficiency, whether from a dirty burner or a failing heat exchanger, burns more gas to produce the same heat. Austin Energy gas customers in older Crestview homes notice this most in January.
Our Furnace Repair Process
Here’s exactly how a furnace repair call works with Cold Harbour Heating and Air Austin. No mystery, no waiting around wondering what’s happening:
- You call (361) 204-1605 and talk to a live person. Not a voicemail tree. A person who writes down your address, your furnace’s symptoms, and a window that actually works for your schedule. We show up when we said we would.
- The technician diagnoses the problem and shows you what’s wrong. We don’t just point at a part and name a number. We take you to the furnace, show you the failed igniter or cracked limit switch, and explain in plain English what it does and why it broke.
- You get a written price before any work starts. The price is on paper, in your hand, before a single tool comes out of the bag. It doesn’t change at the door, and it doesn’t grow after the repair.
- We fix it the same visit whenever parts are on the truck. We carry igniters, flame sensors, limit switches, blower capacitors, and control boards for most major brands on the truck. For uncommon parts, we tell you upfront what the timeline looks like.
- We test the furnace through three full heating cycles before we leave. Not one. Three. We want to see it light, heat, and shut off correctly every time. Then we clean up the work area and walk you through what was done.
- You get the 365-Day Done Right Promise in writing before we go. If that same repair fails within a full year, we come back and fix it at no charge. Written down, not verbal. That’s The Kingswell Way, and it’s been our standard for every repair since 2003.
Furnace Repair Pricing in Austin
Furnace repair costs vary by the part, the furnace’s age, and how accessible the unit is. Here’s what homeowners in Austin can expect to pay for common repairs, parts and labor included:
- Flame sensor cleaning or replacement: $120 to $210. This is the most common repair we do, and it’s usually done in under an hour.
- Igniter replacement: $150 to $280. Hot surface igniters are ceramic and they crack over time. If your furnace tries to light but never catches, this is the likely culprit.
- Limit switch replacement: $130 to $240. A failed limit switch makes the furnace think it’s overheating when it isn’t, which leads to short-cycling or a no-heat condition.
- Blower motor capacitor: $110 to $190. The capacitor gives the blower motor its starting kick. When it fails, the blower hums but doesn’t turn.
- Control board replacement: $300 to $550. More expensive, but if the board is fried, your furnace won’t do anything at all. We diagnose these carefully before recommending replacement because not every dead furnace is a dead board.
- Heat exchanger replacement: $700 and up, depending on brand and furnace age. In many cases, a cracked heat exchanger on a furnace older than 15 years means repair doesn’t make sense, and we’ll tell you that honestly even if it means less work for us.
What drives the price up or down? Furnace brand matters less than most people think. What matters more is the part’s cost, how long the repair takes, and whether your furnace is in a tight attic in a Mueller bungalow or a walk-in closet in a Steiner Ranch two-story. Attic work takes longer, and longer labor means a higher total. That’s why we give the written price after a diagnosis, not over the phone. Estimates are free at (361) 204-1605, and the price you see is the price you pay.
On furnaces over 15 years old, we’ll always walk you through the repair-versus-replace math. If a heat exchanger is cracked and the furnace is nearing the end of its service life, replacing the furnace might be the smarter money. We won’t upsell you. We’ll show you the numbers and let you decide. The home page explains more about how we handle that conversation.
What We Work On
Our technicians are factory-trained on nine major residential HVAC brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Austin, we see a lot of Trane and Lennox systems in older neighborhoods and a growing number of Daikin and York units in newer construction. Whatever’s already in your home, the technician who shows up knows the system without a learning curve.
Why Austin Homeowners Call Cold Harbour
Most of our furnace repair calls come from people who’ve been burned before. A no-show. A diagnosis that changed after the technician got to the house. A repair that quit a month later with no recourse. That’s exactly what the Kingswell Way was built to prevent, and Victor Mancini has run Cold Harbour Heating and Air Austin on those standards since the day the company was founded in 2003. A cold harbour, in the old sense of the word, was a roadside shelter where travelers waited out the weather. Comfort in any season is the job. Not a slogan. The job.
FAQs – Furnace Repair
How much does furnace repair cost in Austin?
Most furnace repairs in Austin run $150 to $650, parts and labor included. Simple fixes like flame sensor cleanings sit at the low end; control board replacements at the high end. A cracked heat exchanger can exceed $700, and in those cases we’ll show you the repair-versus-replace numbers before you commit. Call (361) 204-1605 for a free estimate.
Is it cheaper to repair or replace a furnace?
If the repair costs less than a third of what a new furnace would cost and the furnace is under 12 years old, repair usually makes sense. If the furnace is 15-plus years old and the failed part is the heat exchanger, replacement often costs less in the long run because the repair is expensive and the remaining lifespan is short. We’ll lay out both numbers and let you decide.
Can you fix my furnace the same day?
In most cases, yes. We keep common replacement parts like igniters, flame sensors, limit switches, and capacitors on the truck for most major brands. If your furnace needs a part we don’t carry, we’ll tell you exactly when we can have it and when we’ll be back. Call (361) 204-1605 and we’ll give you a clear timeline on the first call.
What does the 365-Day Done Right Promise cover?
Every furnace repair from Cold Harbour Heating and Air Austin includes a written guarantee valid for 365 days. If the repair fails in that window, we return and correct the work at no additional charge. The guarantee is written down and handed to you before the technician leaves. No verbal promises, no fine print.
Is furnace repair dangerous to try myself?
Furnace repair involves gas lines, electrical wiring, and combustion, which is why we recommend calling a trained professional rather than attempting DIY fixes. A mistake with a gas valve or a cracked heat exchanger can create a carbon monoxide hazard that’s invisible and odorless. If your furnace is acting up, call (361) 204-1605 and a live person will help, any hour of the day or night.
