AfterFurnace Replacement in Austin, TX
Furnace replacement in Austin typically costs between $3,800 and $7,500 for a standard single-stage system in a 1,500 to 2,500 square foot home, with high-efficiency or two-stage units running $8,000 to $12,000 installed. Most replacements take one full day, and in Austin’s December-through-February cold snaps, we prioritize no-heat situations so you’re not waiting through a 28-degree night. At Brandt HVAC Co Austin, we send you the technician’s name and photo before they arrive, hand you a written price before any work starts, and back the entire install with our 365-Day Done Right Promise.
If your furnace is over 15 years old, needs a repair that costs more than half its remaining value, or you’re seeing repeated breakdowns each winter, replacement is usually the honest recommendation. Our Heating & Furnace in Austin work covers repairs and maintenance too, but when the math says a new system makes more sense, we’ll tell you that plainly and walk you through what it costs. Call (361) 326-1553 and a live person answers, any hour.

When You Need Furnace Replacement
Some Austin homes go years without realizing their furnace is dying until a January cold front hits and the house won’t get above 58 degrees. Here are the situations where replacement is the smarter call than another repair:
- Furnace age over 15 years. Most gas furnaces in Austin last 15 – 20 years. At that age, even a working unit is running at 60 – 70% of its original efficiency, which means you’re paying for heat that’s going up the flue.
- Repair costs piling up. If you’ve spent $600 on a blower motor in November and now the heat exchanger is cracked in February, those two repairs combined are a third of a new system. A quality replacement stops the pattern.
- Uneven heating across rooms. Older single-stage furnaces blast full heat then shut off, which leaves the back bedroom in Hyde Park or the upstairs in Allandale noticeably colder. A new two-stage or variable-speed unit holds a steadier temperature.
- Rising gas bills without rising comfort. When your December and January bills creep up year after year but the house feels the same, the unit is working harder to deliver less. Austin’s humidity swings also make older heat exchangers work against damp, rust-prone conditions.
- Safety shut-offs or carbon monoxide alerts. A cracked heat exchanger is a genuine safety issue. If a technician has flagged it, don’t wait. Replacement is the only fix that protects the people in the house.
- Constant short-cycling. If the furnace kicks on and off every few minutes, it’s oversized or failing. Austin’s relatively mild winters mean many original installs were oversized anyway, which shortens equipment life.
Our Furnace Replacement Process
We don’t show up with a truck full of parts and a vague estimate. Here’s exactly how a replacement works with Brandt HVAC Co Austin, step by step:
- You call (361) 326-1553 and a live person answers. No voicemail, no callback queue, no automated tree. We take your details and schedule a visit that works for you.
- You receive your technician’s name and photo before arrival. This is Threshold Verified in action – our standard for telling you exactly who’s coming. Every technician is background-checked and identity-verified. When they arrive, they show a photo ID badge at the door. If anyone shows up you weren’t told to expect, that visit is on us and we make it right.
- We evaluate your current system and your home. Square footage, ceiling height, window exposure, insulation levels, and how your home sits on the lot. Austin’s climate matters here: we size for both the occasional 25-degree night and the long mild stretches where the furnace mostly waits.
- You get a written price before any work starts. This is non-negotiable for us. The price includes the unit, labor, removal of the old furnace, any needed duct adapters, and the full installation. You see the number in writing and you agree to it before we touch a tool.
- Installation day. Most replacements are done in one day. Our technicians protect the work area, remove the old unit, set the new furnace, connect gas and electrical, and test the whole system for airflow, temperature rise, and safe venting.
- You get a written guarantee. Every replacement includes a written document stating exactly what’s covered and for how long. And it’s backed by the 365-Day Done Right Promise: if anything isn’t done right, we return and make it right, at no charge.
Furnace Replacement Pricing in Austin
Here’s what you can expect to pay for a furnace replacement in Austin, parts and labor included. These are real ranges, not teaser numbers:
- Standard single-stage furnace (80% efficiency): $3,800 – $5,500. Good for smaller homes and mild winters, but you’ll feel the temperature swing in older, draftier houses.
- Two-stage furnace (96% efficiency): $5,500 – $8,000. Runs on low stage most of the time, which means steadier heat and lower gas bills. The most common choice for Austin homes.
- Variable-speed or modulating furnace (96 – 98% efficiency): $7,500 – $12,000. The quietest and most even option, ideal for larger homes or anyone sensitive to temperature swings or fan noise.
What moves the price: the size of your home, whether you need new ductwork or just adapters, whether you’re switching from gas to electric or vice versa, and whether you want a smart thermostat wired in. Brand choice matters too – York and Daikin tend to sit at the value end of the range, while American Standard and Bryant land mid-to-premium.
We don’t quote over the phone without seeing the home, because a bad size estimate wastes your money. The estimate is free, it’s in writing, and the price we quote is the price you pay. No add-ons after the fact. Call (361) 326-1553 to schedule a free replacement estimate.

FAQ – Furnace Replacement
How much does furnace replacement cost in Austin?
A furnace replacement in Austin typically runs $3,800 to $12,000 installed, with most homes falling between $5,500 and $8,000 for a two-stage high-efficiency unit. The exact number depends on your home’s size, insulation, existing ductwork, and the brand and efficiency level you choose. Call (361) 326-1553 for a free in-home estimate – we give you the number in writing before any work begins.
Is it cheaper to repair or replace my furnace?
If your furnace is under 10 years old and the repair is a single component like an igniter or blower capacitor, repair almost always makes more sense. If the unit is over 15 years old, the heat exchanger is cracked, or you’ve had two repairs in the same season, replacement usually costs less over the next three years than continuing to patch the old system. We’ll tell you which side of that line your furnace is on, based on what we find, with no pressure either way.
Can you replace a furnace the same day?
In most cases, yes – if the unit is in stock and we have the crew available, we can complete a standard furnace replacement same-day, especially for no-heat emergencies during Austin’s cold snaps. Older homes with unusual ductwork or venting may require a follow-up ordering window. Call (361) 326-1553 and we’ll give you a straight answer on timing.
Do you work on my furnace brand?
We install and service all major residential HVAC brands, including York, Daikin, Bryant, American Standard, Carrier, Trane, Lennox, and Goodman. If you have an existing brand you like, we’ll quote a compatible unit. If you’re unsure what you need, we’ll recommend options that fit your home and budget, with a written price for each.
