AfterAC Replacement in Austin, TX
AC replacement in Austin typically costs between $4,500 and $12,500 depending on home size, efficiency rating, and ductwork condition, with most jobs completed in one day. If your system is over 12 years old, needs a compressor or coil replacement, or runs on R-22 refrigerant (Freon), replacement usually makes more financial sense than another repair. At Halden Heating and Air Austin, every replacement quote comes as a written price before any work starts, and you’ll know exactly who’s coming to your door and when. We’ve been replacing AC systems across Austin since 2004, and our AC Repair & Installation team handles everything from a straightforward outdoor unit swap to full system and ductwork replacement.

When You Need AC Replacement
Some AC problems are worth fixing. Others are money pits. Here’s what we tell Austin homeowners to look for when deciding between repair and replacement:
- Your system is 12 to 15 years old. The average air conditioner in Central Texas lasts 12 to 15 years. If yours is in that range and needs a major component like a compressor or evaporator coil, putting $2,000 into a 14-year-old unit usually doesn’t pencil out. In neighborhoods like Allandale and Crestview where homes date to the 1960s and 1970s, we regularly see original equipment being retired for the first time.
- It runs on R-22 refrigerant (Freon). R-22 was phased out of new production years ago, and the remaining supply is expensive. A refrigerant recharge on an R-22 system can run $150 to $300 per pound, and older systems often need 6 to 10 pounds. That’s a bill nobody wants twice.
- Your compressor failed. The compressor is the heart of the system. When it goes on an older AC, replacement cost usually lands at 40% to 60% of a full new system. In Austin’s heat, where your AC runs hard from May through October, a compressor replacement on an aging unit is often a bridge to nowhere.
- Repair costs are stacking up. If you’ve spent $500 or more on repairs in the last two years and the system is over 10 years old, the math points toward replacement. A good rule of thumb: multiply the repair cost by the age of the unit. If that number exceeds $5,000, replacement is the smarter move.
- Your energy bills keep climbing. Older systems run at 10 to 14 SEER (Seasonal Energy Efficiency Ratio, the MPG of air conditioners). New systems in Austin typically run 16 to 20 SEER. That difference can cut your summer cooling bills by 20% to 40%, which matters when Austin sees 100-degree days from June through September.
- Uneven cooling or constant cycling. If some rooms in your house are 8 degrees warmer than others, or your system short-cycles (kicks on and off every few minutes), it’s working harder than it should. In two-story homes in Mueller or Circle C, this is often a sign the system was undersized from the start.
Our AC Replacement Process
We built our replacement process around the same standard you’d expect from a rideshare app: you see who’s coming, when they’ll arrive, and what it costs before anything happens. Here’s how it works:
- Book online or call (361) 202-9170. You’ll speak to a live person or use our online booking. Either way, you get a confirmed appointment with a real arrival time, not a four-hour window.
- We assess your current system and your home. Our technician checks your existing equipment, ductwork, insulation, and square footage, then talks through your comfort priorities. We service major brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we’ll match your replacement to what your home actually needs, not whatever is on the truck.
- You get a written price before any work starts. This is non-negotiable for us. You see exactly what the equipment costs, what the labor costs, and what the total is. No door-step surprises, no “while we’re here” add-ons you didn’t approve.
- Installation day. Our background-checked, uniformed technicians arrive at the scheduled time. Most replacements take 4 to 8 hours. We’ll install the new system, test it, clean up, and walk you through everything before we leave.
- Your 365-Day Done Right Promise starts. Every replacement includes our written guarantee. If something isn’t right within a year, we make it right at no charge. That’s the promise, in writing, on every completed job.
AC Replacement Pricing in Austin
Here’s the straight answer: most AC replacements in Austin land between $4,500 and $12,500. What moves the number is the size of your home, the efficiency rating you choose, and whether your ductwork needs work. Here’s the breakdown:
| System Type | Typical Austin Price Range | Best For |
|---|---|---|
| Basic 14 – 16 SEER single-stage | $4,500 – $6,500 | Smaller homes, budget-conscious replacements |
| Mid-range 16 – 18 SEER two-stage | $6,500 – $9,000 | Most 3 – 4 bedroom Austin homes |
| High-efficiency 18 – 20+ SEER variable-speed | $9,000 – $12,500 | Larger homes, maximum comfort and efficiency |
| Ductwork modifications | $500 – $2,500 additional | Homes with damaged or undersized ducts |
What affects the final price? Home size (square footage drives system tonnage), existing ductwork condition, brand choice (Daikin and York tend to land in the mid-range, Bryant and American Standard span mid-to-high), and whether you’re replacing a heat pump or a traditional AC with a furnace. Austin’s climate also matters: our summers demand systems sized for sustained 100-degree heat, which sometimes means upsizing from what a generic national formula would recommend. If you’re low on coolant, a Refrigerant Recharge may help short-term, but an undersized unit will still struggle.
Call (361) 202-9170 for a free, no-pressure estimate. You’ll get a written price, and you can decide on your own timeline. That’s how we’ve operated since 2004.

FAQs – AC Replacement
How much does AC replacement cost in Austin?
AC replacement in Austin typically costs $4,500 to $12,500, with most 3-4 bedroom homes landing between $6,500 and $9,000 for a mid-range 16-18 SEER system. Your exact price depends on home size, ductwork condition, and the efficiency rating you choose. Call (361) 202-9170 for a free written estimate with no obligation.
Is it cheaper to repair or replace my AC?
If your system is under 10 years old and the repair is under $500, repair usually wins. If it’s over 12 years old, runs on R-22 refrigerant, or needs Compressor Repair, replacement typically costs less over the next five years. We’ll give you honest numbers for both options before you decide. Call (361) 202-9170 and we’ll walk you through the math at no charge.
Can you replace my AC the same day?
In most cases, yes. We stock common system sizes and brands including York, Daikin, Bryant, and American Standard, and our technicians can often complete a standard replacement within one business day of your estimate. During Austin’s peak summer months, same-day availability tightens, so call (361) 202-9170 early if your system is down.
Do you offer financing on AC replacement?
Yes, financing is available on qualifying replacement projects. We’ll review your options during the estimate, and you’ll see the full written price and payment terms before any work begins. Call (361) 202-9170 for details.
How long does an AC replacement take?
A standard AC replacement takes 4 to 8 hours from arrival to cleanup. If ductwork modifications are needed, that can add a day. We’ll give you a clear timeline with your written estimate.
