AfterAC Replacement in Austin, TX
AC replacement in Austin typically costs between $5,800 and $12,400 for a complete system swap, depending on home size, efficiency rating, and ductwork condition. Most Austin homeowners replace their air conditioner every 12 to 15 years, and the intense Central Texas heat means equipment here runs harder and wears out faster than in cooler climates. If your unit is past year 12 and repair bills are piling up, replacement is usually the smarter money. Brandt HVAC Co Austin gives you a written price before any work starts, so you’ll know the full number before you commit. Call us at (361) 326-1553 for a free replacement estimate.
We handle full-system AC replacement as part of our broader AC Repair & Installation in Austin work. Some homes need a complete outdoor condenser and indoor coil swap, others need the air handler replaced too, and a few need ductwork modifications. Whatever your situation, we tell you plainly what’s needed and what it costs.
Key Takeaways
- Replacement cost in Austin: $5,800 – $12,400 for most single-family homes.
- When it makes sense: Repairs exceeding 30 – 40% of replacement cost, or equipment over 12 years old.
- Brandt difference: Written price first, background-checked technician sent by name and photo, live person on the phone 24/7.
- Guarantee: Every replacement includes a written warranty and the 365-Day Done Right Promise.
When You Need AC Replacement
Not every AC problem means replacement. But Austin’s climate pushes equipment hard, and there’s a point where continuing to invest in our AC repair installation services for an aging system is throwing money away. Here’s what tells us it’s time to consider a new unit.
- Your AC is 12 to 15 years old and needs a major repair. Compressor failure on a 14-year-old unit often runs $2,000 – $3,500 to fix. That’s money better spent toward a system that will actually cool your home efficiently.
- Your energy bills keep climbing. In neighborhoods like Allandale and Mueller, we regularly see older 10-SEER units running 30 – 40% less efficiently than modern 16-SEER systems. That inefficiency shows up on your Austin Energy bill every summer month.
- The system still uses R-22 refrigerant. R-22 was phased out years ago, and refilling an old unit with remaining R-22 stock now costs $150 – $250 per pound. A typical recharge means 4 – 8 pounds, and that’s money you’ll spend again when it leaks again.
- Uneven cooling between rooms. If your living room is 72 degrees but the back bedroom is 82, your ductwork or aging equipment isn’t distributing air properly. Sometimes the fix is simple, sometimes it’s replacement.
- You’re tired of repair calls every summer. When you’ve had us out twice in one season, or three times in two years, replacement often costs less per year of cooling than keeping the old unit alive.
- The compressor is dead and the system is out of warranty. This is the big one. A dead compressor on a unit over 10 years old almost always means replacement is the financially sound call.
Not sure which side of the line you’re on? We’ll tell you straight. If repair makes sense, we’ll recommend repair. If replacement is the honest answer, we’ll show you the numbers for both options so you can decide with your eyes open.
Our AC Replacement Process
- Free on-site assessment. We measure your home’s square footage, inspect your current equipment, check your ductwork, and evaluate your electrical panel. We look at sun exposure, window placement, and insulation levels in your specific Austin neighborhood, because a home in Westlake has different cooling demands than one in Crestview.
- Written proposal with exact pricing. You get a written quote detailing the equipment, installation labor, any ductwork changes, and the total cost. No work starts until you see and approve that number in writing. That’s our rule on every job, no exceptions.
- Equipment selection by need, not commission. We’ll recommend the right efficiency level and brand for your home. We install major residential brands like American Standard, Bryant, and Daikin, and we’ll explain why a particular unit fits your situation.
- Scheduled installation with your technician introduced by name. Before we arrive, you’ll receive the name and photo of the technician coming to your door. When they ring the bell, they’ll show a photo ID badge. That’s the Threshold Verified standard, and it means you always know exactly who is entering your home.
- Full system replacement and testing. We remove the old equipment, install the new system, verify refrigerant charge, test airflow, and walk you through the new thermostat settings before we leave.
- Written guarantee and 365-Day Done Right Promise. Every replacement includes a written warranty stating exactly what’s covered and for how long. If anything isn’t right within 365 days, we return at no charge and make it right.
AC Replacement Pricing in Austin
Here’s what you can expect to spend on AC replacement in Austin, based on the work we do across the metro area. These are real numbers from real jobs in neighborhoods like Hyde Park, Bouldin Creek, and Rosedale.
- 14 – 16 SEER single-stage system (3-ton): $5,800 – $7,200 installed
- 16 – 17 SEER two-stage system (3 – 4 ton): $7,200 – $9,500 installed
- 18 – 20 SEER variable-speed system (4 – 5 ton): $9,500 – $12,400 installed
- Ductwork modifications or partial replacement: $800 – $3,000 additional, depending on scope
- Thermostat upgrade (smart thermostat included with most replacements): $0 – $250
What affects the final number? Home square footage and ceiling height, the condition of existing ductwork, whether you need Capacitor Replacement, an electrical panel upgrade, and the efficiency rating you choose. A two-story home with zoned cooling costs more than a single-story ranch, and replacing a system in an older Austin home with original ductwork may require more work than a newer build.
Every proposal from Brandt HVAC includes a written line-by-line price before any work starts. You’ll never get a verbal estimate followed by surprise charges. Call (361) 326-1553 and we’ll schedule a free assessment at your Austin home.
Why Choose Brandt HVAC for AC Replacement
The name Brandt comes from an old word for a firebrand, the burning stick that kept a home warm through the winter. The parallel isn’t lost on us. Keeping a home comfortable in Austin, where summers push 100 degrees for weeks on end, is serious work.
Here’s what we do differently:
- You know who’s coming before they arrive. We send the technician’s name and photo ahead of every visit. When the doorbell rings, that technician shows a photo ID badge. This is the Threshold Verified standard, and it’s built for people who don’t like the idea of a stranger at the door.
- Written price, every time. No work starts without a written quote you’ve seen and approved. Never an estimate, never a “we’ll see when we get in there.” The price is the price.
- Live phone answers, 24/7. A real person answers our phone at 2 p.m. and at 2 a.m. No voicemail, no callback queue, no automated phone tree. When your AC dies on a Saturday night in August, you talk to a person.
- 365-Day Done Right Promise. If your replacement isn’t done right, we make it right. If something fails within the guarantee period, we return free of charge. No argument, no additional fee.
FAQs – AC Replacement
How do I know if I should repair or replace my AC?
You should replace your AC when the repair cost exceeds 30 – 40% of the cost of a new system, when your unit is over 12 years old, or when your energy bills have risen significantly despite regular maintenance. In Austin, where cooling season runs from April through October, an aging 10-SEER unit costs far more to run than a modern 16-SEER replacement. If you’re on the fence, call (361) 326-1553 and we’ll give you honest numbers for both options.
How long does AC replacement take?
Most AC replacements in Austin are completed in one day, typically 4 to 8 hours of work. Larger jobs involving Compressor Repair, full ductwork replacement or electrical panel upgrades may extend into a second day. We’ll give you a clear timeline in your written proposal before any work begins.
How much does AC replacement cost in Austin?
AC replacement in Austin costs $5,800 – $12,400 for most single-family homes. The range depends on home size, system efficiency, brand, and whether ductwork needs modifying. We provide a free on-site assessment and a written quote before any work starts, so you’ll know your exact cost upfront. Call (361) 326-1553 to schedule yours.
Do you remove the old AC unit?
Yes, full removal and disposal of your old equipment is included in every AC replacement quote from Brandt HVAC. We handle Refrigerant Recharge if needed, haul away the old condenser, coil, and related components, and we leave your property clean.
