AfterFurnace Replacement in Austin, TX
Furnace replacement in Austin typically costs between $4,800 and $9,500 for a standard single-family home, with most installations completed in a single day. That range covers the furnace itself, labor, and the removal of your old unit. If your furnace is older than 15 years, needs repairs that exceed half the cost of a new unit, or has a cracked heat exchanger, replacement is usually the smarter financial choice. At Cold Harbour Heating and Air Austin, we give you a written price before any work begins, so you know the full cost before you decide.
We’ve been installing furnaces in Austin homes since 2003, and we treat every replacement as a long-term decision, not a quick swap. Our Heating & Furnace work carries the same written guarantee as everything else we do. If you’re weighing repair against replacement, call us at (361) 204-1605 and we’ll walk through the numbers with you.

When You Need Furnace Replacement
Some furnace problems are worth fixing. Others are a signal that the equipment has reached the end of its working life. Here’s what pushes an Austin homeowner toward replacement rather than another repair:
- Your furnace is 15 years old or older. Even a well-maintained furnace loses efficiency and reliability after 15 years. In Austin’s hill country homes, where furnaces sit in closets and attics with tight clearances, age hits harder because airflow restrictions and heat buildup accelerate wear.
- The heat exchanger is cracked. This is the part that separates combustion gases from the air you breathe. Austin code requires the unit be shut down if a crack is found. Replacement is almost always the right call, not a patch job.
- Repair costs are climbing. If the latest quote is more than half the price of a new furnace, stop patching. A $350 blower motor here, a $500 control board there, and suddenly you’ve spent a new unit’s down payment on borrowed time.
- Your energy bills keep rising with no change in usage. Older furnaces run at 60 to 70 percent fuel efficiency. Modern units run at 80 percent minimum, with high-efficiency models at 95 percent or better. In Austin winters, that difference shows up on every January bill.
- Rooms heat unevenly. If you’ve got one bedroom that’s always cold while the living room roasts, the problem may be the furnace’s blower and burner cycling out of step. A new, correctly sized furnace fixes airflow imbalance that years of repairs never addressed.
- Frequent short cycling or strange smells. A furnace that turns on and off every few minutes is wasting fuel and straining its parts. A persistent metallic or burning smell that doesn’t go away after a cleaning often means the heat exchanger or burner assembly is failing.
Our Furnace Replacement Process
Replacing a furnace in Austin isn’t a one-size-fits-all job. Here’s how we approach it, step by step, so there are no surprises at the end.
- Free in-home assessment. A technician measures your home’s square footage, checks ductwork and insulation, and asks how you actually use your heat. Austin homes range from 1970s ranch layouts to modern open floor plans, and each needs a different furnace size.
- Written quote, no pressure. Before we leave, you get a printed price. That number includes the furnace, labor, removal of the old unit, and any permit fees. The price does not change at the door. This is the Kingswell Way: say the price before the work, and stick to it.
- Scheduling around your life. We give you a firm arrival window and we keep it. Most standard replacements take one full day. If your home needs ductwork modifications or a new flue liner, we’ll tell you in the quote and schedule accordingly.
- Clean removal and careful installation. Our background-checked, uniformed technicians lay down drop cloths, remove the old furnace, and install the new one. We clean up every scrap of packaging, old parts, and debris before we leave. You shouldn’t know we were there except for the warm air.
- System walkthrough and written guarantee. We walk you through the new thermostat, show you where the filter goes, and explain the warranty. Each replacement carries a written 365-day guarantee. If the installation fails within that year, we return and correct it at no charge. On paper, not just a promise.
Furnace Replacement Pricing in Austin
What you’ll pay for a furnace replacement in Austin depends on four things: the size of your home, the efficiency rating you choose, the condition of your ductwork, and whether any code updates are required. Austin’s mix of slab foundations and pier-and-beam homes also affects the job, since older crawlspace ductwork sometimes needs sealing or replacement before a new furnace can deliver its rated efficiency.
Here are the ranges we see most often in Austin:
| Furnace Type | Typical Installed Cost in Austin |
|---|---|
| 80% efficiency, single-stage (2,000 sq ft home) | $4,800 – $6,200 |
| 95% efficiency, two-stage (2,000 sq ft home) | $6,500 – $8,400 |
| High-efficiency variable-speed (larger or custom homes) | $8,000 – $9,500+ |
| Ductwork sealing or modification | Add $800 – $2,500 depending on scope |
Most Austin homeowners choose the 80% single-stage unit unless they plan to stay in the home more than seven years, in which case the 95% two-stage often pays for itself through lower gas bills. York and Bryant both make solid mid-range options we install regularly. American Standard’s variable-speed models are popular in larger West Austin homes where even heat distribution matters more.
The written quote we hand you before any work begins includes everything: the furnace, labor, old unit removal, and any required permits. No line-item surprises after the fact. Call (361) 204-1605 and we’ll schedule a free assessment and give you a number in writing.
Frequently Asked Questions About Furnace Replacement
How long does furnace replacement take in Austin?
Most standard furnace replacements in Austin are completed in one working day, usually 4 to 8 hours depending on access and whether ductwork needs attention. Our technicians arrive in a firm window and don’t leave until the job is done and the space is clean. For an exact timeline for your home, call (361) 204-1605. We’ll give you a straight answer based on the specifics.
Is it cheaper to repair or replace my furnace?
If your furnace is under 10 years old and the repair is a simple part like an igniter or flame sensor, repair is usually cheaper. But if the unit is over 15 years old or the repair quote exceeds half the cost of a new furnace, replacement makes better financial sense. We’ll give you both numbers in writing and let you decide. Call (361) 204-1605 for an honest comparison.
What size furnace do I need for my Austin home?
The right size depends on square footage, ceiling height, insulation, window orientation, and how many people live in the home. A 2,000-square-foot Austin home typically needs a 60,000 to 80,000 BTU furnace, but a poorly insulated 1970s home may need more while a tightly sealed newer build may need less. Oversizing is worse than undersizing: an oversized furnace short-cycles and wastes gas. We measure and calculate load before recommending anything.
Do you offer financing or payment plans for furnace replacement?
We keep pricing straightforward and give you a written quote before work begins. If you want to spread out the cost, we can discuss payment options during the estimate, but we won’t push financing as a sales tactic. The number you’re quoted is the number you pay, and the 365-day guarantee is included. Call (361) 204-1605 to talk through your situation.
