AfterAC Replacement in San Antonio, TX
AC replacement in San Antonio typically runs $6,500 to $14,500 for a full system swap, depending on home size, efficiency rating, and ductwork condition. Most replacements take one full day, and in the San Antonio heat, a failed compressor or leaking coil on a 12+ year old unit is usually a stronger case for replacement than another Compressor Repair. If your system has needed refrigerant twice in two years or the repair quote is creeping past $2,500, you’re at the point where a new unit starts making real financial sense.
At Brandt HVAC Co San Antonio, we approach AC replacement the way we approach every job: you’ll know the price before any work begins, you’ll know the name and face of the technician walking through your door before they arrive, and you’ll have a written guarantee on the installation. If you’re weighing repair against replacement, start with our AC Repair & Installation in San Antonio page to understand the full picture, then call us at (361) 470-8872 for a straight answer on your specific system.

When You Need AC Replacement
Not every failing air conditioner needs to be replaced. Some issues, like a bad Capacitor Replacement or a clogged condensate drain, are routine repairs. But San Antonio’s climate puts enormous strain on residential cooling equipment, and we regularly see systems in neighborhoods like Alamo Heights, Stone Oak, and Helotes that have been worked hard for 15 years and are simply done. Here’s when replacement becomes the smart call:
- Your compressor has failed. The compressor is the heart of the system. On a unit that’s 10+ years old, a compressor replacement often costs 40-60% of a new system, and you’re still left with aging coils, a worn blower, and no meaningful warranty.
- Your system uses R-22 refrigerant. R-22 (often called Freon) was phased out of production in 2020. If your older system has a refrigerant leak, recharging it means paying premium prices for dwindling stock, and every recharge is money that would be better spent on a new system designed for modern refrigerant.
- You’ve had two or more major repairs in two years. When repair costs start stacking up past $2,000 in a short window, you’re funding a system that’s already telling you it’s done.
- Your energy bills keep climbing despite the same usage. A system that loses efficiency as it wears out works harder to hit the same temperature. On a San Antonio July, that difference shows up on your CPS Energy bill.
- Your evaporator coil is leaking. Coil replacement on an older system is a major job that often costs $1,800 to $3,200. If the system is past 12 years old, we’ll be straight with you: that money usually belongs in a new unit.
- Uneven cooling or constant short-cycling. Rooms that never get comfortable, a system that turns on and off every few minutes, or humidity that lingers indoors are all signs the equipment is no longer matched to your home’s needs.

Our AC Replacement Process
We built our replacement process around one idea: you should never feel unsure about who’s in your home or what you’re paying for. Every step is designed to remove the unknowns that make AC replacement stressful.
- Call and talk to a live person. When you call (361) 470-8872, a real person answers, 24 hours a day. No phone trees, no voicemail, no waiting for a callback. We’ll schedule a time that works for you and tell you who will be arriving.
- Meet your technician by name and photo before the visit. Before we arrive, you’ll receive the name and photo of the technician coming to your home. When they show up, they’ll be in uniform and will present a photo ID badge at the door. That’s the Threshold Verified standard, and it’s how we do every visit.
- Get a full system assessment and a written price. We evaluate your existing equipment, your ductwork, your home’s square footage, and your cooling needs. Then we quote you a written price for the replacement. Nothing gets ordered, and no work begins, until you’ve seen the number and agreed to it in writing.
- We install the new system, typically in one day. We remove the old equipment, install the new indoor and outdoor units, connect the refrigerant lines, and verify every electrical and safety component. We work clean, and we respect your home throughout the job.
- You get a written guarantee and a walkthrough. Every installation comes with a written guarantee that spells out exactly what’s covered and for how long. Before we leave, we walk you through your new system, show you the thermostat operation, and answer any question you have.
AC Replacement Pricing in San Antonio
Here’s what homeowners in San Antonio can expect to pay for a full AC replacement, installed, with all permits and refrigerant included:
- 3-ton system, 14 SEER2 (entry-level efficiency): $6,500 to $8,500
- 4-ton system, 16 SEER2 (mid-range efficiency): $8,500 to $11,000
- 5-ton system, 17-20 SEER2 (high efficiency): $11,000 to $14,500
- Variable-speed or premium comfort system: $14,000 to $18,000+
Several factors move that number up or down. Home size and cooling load requirements set the tonnage. Ductwork condition matters more than most people expect: if your ducts are leaking or undersized, a new high-efficiency system won’t perform, and you may need duct sealing or modification. The brand you choose (we install Rheem, York, Daikin, Bryant, and every other major residential line) shifts the price modestly. And efficiency rating (SEER2) is a balancing act between upfront cost and long-term energy savings.
The most important number is the one we give you before any work starts. When we quote a replacement, the price you see is the price you pay, and it’s in writing before we order a single piece of equipment. If you want to know what your specific situation will cost, call (361) 470-8872 for a free estimate. We’ll tell you exactly what to expect, down to the dollar.
FAQs – AC Replacement
How much does AC replacement cost in San Antonio?
AC replacement in San Antonio costs $6,500 to $14,500 for a full system, with most mid-range 3-4 ton installations landing between $8,000 and $11,000. The final price depends on system size, efficiency rating, brand (we install Rheem, York, Daikin, and Bryant, among others), and ductwork condition. Call (361) 470-8872 for a written quote specific to your home, no strings attached.
Is it cheaper to repair or replace my AC?
If the repair costs less than 25% of the cost of a new system and your unit is under 10 years old, repair is usually the better call. If your system is 12+ years old and needs a compressor or evaporator coil, replacement nearly always makes more sense, because you’re putting major money into a unit that will likely need another costly repair soon. Call us at (361) 470-8872 and we’ll give you our honest read on which path protects your money better.
Can you replace my AC the same day?
In most cases, we can replace your AC within a few days of your initial call, and the installation itself is done in a single day. True same-day replacement is sometimes possible depending on your system’s specifications and equipment availability, especially during San Antonio’s peak cooling season. Call (361) 470-8872 to find out how quickly we can get you scheduled.
What brands do you install?
We install every major residential HVAC brand, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The right brand for your San Antonio home depends on your budget, efficiency goals, and existing ductwork. We’ll walk you through the trade-offs plainly, without putting our thumb on the scale.
How long does an AC replacement take?
A standard AC replacement takes one full day, with our crew typically arriving in the morning and finishing by late afternoon. We remove the old equipment, install the new system, charge the refrigerant, and test everything before we leave. Complex jobs with ductwork modifications or heat pump conversions can take a second day, and we’ll tell you upfront if that’s the case.
What is the 365-Day Done Right Promise?
The 365-Day Done Right Promise is our written commitment on every installation and repair we complete. If something isn’t right within 365 days, we come back and make it right, at no additional charge to you. The details are in writing on every job, so you know exactly what’s covered and for how long before we ever start work.
