AfterRefrigerant Recharge in San Antonio, TX
A refrigerant recharge in San Antonio typically costs between $150 and $450 for most residential systems, depending on how much refrigerant the system needs and whether a leak must be located first. At Brandt HVAC Co San Antonio, every recharge starts with a leak check, so you’re not paying to refill a system that will just empty again. We provide a written price before any work begins, and the repair is covered by our 365-Day Done Right Promise.
Refrigerant is the fluid that moves heat out of your home. When the level drops, your AC can’t cool properly, no matter how long it runs. If your system is low, the problem is almost always a leak somewhere in the lines or coils. Adding refrigerant without finding and fixing that leak is a temporary fix at best. That’s why our AC Repair & Installation technicians test the system first, tell you exactly what’s leaking, and give you a written price before we add anything. Call (361) 470-8872 any time, day or night. A live person answers.

When You Need Refrigerant Recharge
Low refrigerant shows up in ways you’ll notice before a technician ever hooks up gauges. Here’s what San Antonio homeowners most often report before calling us:
- Your AC runs constantly but the house won’t get cool. This is the most common sign. The system is working hard but the heat exchange isn’t happening the way it should. In San Antonio’s summer humidity, you’ll feel it inside within an hour or two of the system falling behind.
- Warm air blowing from the vents. Not just “not cold” but noticeably warm. That’s often the refrigerant level dropping below what the evaporator coil needs to pull heat out of the air.
- Ice on the copper lines or the outdoor unit. You’ll see frost or solid ice on the larger line running into the outdoor condenser. Low refrigerant causes the coil temperature to drop below freezing, and the condensation on it ices over. In San Antonio, this happens fast when the humidity climbs above 80 percent and the system has been cycling all afternoon.
- A hissing or bubbling sound near the indoor coil. Refrigerant is under pressure. When it leaks, you may hear it escaping as a faint hiss or a bubbling sound from the coil area. Not every leak you can hear, but some you can.
- Your electric bill jumped in June or July without a change in how you use the AC. A system low on refrigerant runs longer to reach the same temperature. That runtime shows up on your CPS Energy bill within a billing cycle.
- The AC short-cycles at night. If the low-pressure switch trips and shuts the system down, it may restart, run briefly, then cut off again. You’ll hear the outdoor unit start and stop in short bursts.
Our Refrigerant Recharge Process
Here’s exactly how a refrigerant recharge works when you call Brandt HVAC Co San Antonio:
- You call, a live person answers. We take your details over the phone and schedule a time that works for you. Before the technician arrives, you get their name and photo sent to you. They’ll show a photo ID badge at the door. That’s our Threshold Verified standard, and it applies to every visit.
- The technician tests the system with gauges. We connect manifold gauges to the service valves on your condenser and read the pressures on both the high and low side. We check the superheat and subcooling values against the manufacturer’s spec for your unit. That tells us exactly how low the charge is. We service Rheem, York, Daikin, and Bryant units, among other brands, so we know the specific charge specs for your equipment.
- We locate the leak. Low refrigerant means there’s a hole somewhere. We use an electronic leak detector and a visual inspection of the coil, lines, and fittings to find it. In San Antonio, we commonly see leaks at the Schrader valve cores, brazed joints on the lineset, and micro-fractures in the evaporator coil. Coil leaks on units older than ten years are especially common because of the corrosive combination of humidity and airborne dust that settles on the coil after years of cycling.
- You get a written price. Before we open a service valve or add anything, we write down the exact cost: leak repair if needed, refrigerant by the pound, and labor. You approve it first, every time.
- We fix the leak, then recharge. If the leak is repairable, we fix it, pull a vacuum to remove moisture and air from the lines, then charge the system to the manufacturer’s exact specification. We weigh the refrigerant on a scale rather than guessing by pressure. Overcharging a system damages the compressor, and undercharging wastes your money.
- We verify the temperature drop. After the recharge, we run the system and measure the air temperature at the return and the supply. You should see a 15 to 20 degree drop. We also check the compressor amp draw to make sure it’s within rated range. Then we document everything on your invoice. Your repair is guaranteed for 365 days. If it fails within that year, we return at no charge.
Refrigerant Recharge Pricing in San Antonio
Here’s what you can expect to pay in San Antonio for a refrigerant recharge, based on the work we commonly do:
| Service | Typical Range in San Antonio |
|---|---|
| Diagnostic visit with leak check | $89 – $149 |
| R-410A refrigerant, per pound | $50 – $120 per lb |
| Full recharge (2 – 5 lbs, most residential systems) | $150 – $450 |
| Minor leak repair (valve core, Schrader valve, or fitting) | $50 – $200 |
| Evaporator coil replacement (if the coil itself has failed) | $900 – $2,200 |
Several things move the final price. The type of refrigerant your system uses is the biggest one. R-22, used in systems manufactured before 2010, is no longer produced or imported in the United States. Remaining supplies are expensive, often $150 or more per pound, and some San Antonio homes still have R-22 units. If your system uses R-22, we’ll give you an honest recommendation: recharge at the higher cost, or replace the system. We won’t push you either way. We’ll show you the numbers for both.
If your unit uses R-410A, which covers most systems installed after 2010, the recharge will be less expensive. Newer systems may also use R-32, and we handle that as well.
How much refrigerant the system has lost also matters. A small top-off after a valve leak is one thing. A system that’s emptied entirely means the leak was never caught early, and you’ll pay for both the repair and a full charge. If your evaporator coil is the source, and the unit is eight to twelve years old, replacement often makes more sense than patching a failing coil.
Every refrigerant recharge at Brandt HVAC Co San Antonio starts with a free estimate over the phone, and a written price on site before work starts. You’ll never get a surprise number after the work is done. Call (361) 470-8872 and we’ll walk you through what to expect for your specific system.
FAQs – Refrigerant Recharge
How much does a refrigerant recharge cost in San Antonio?
A refrigerant recharge in San Antonio typically costs between $150 and $450 for most residential systems, including the leak check, refrigerant, and labor. The exact price depends on the type of refrigerant your system uses, how much it needs, and whether a leak must be repaired first. Call (361) 470-8872 for a free estimate and we’ll give you a written price before any work starts.
Is it cheaper to recharge or replace an AC unit?
If your system is under ten years old and the leak is a simple valve core or fitting, recharging is far cheaper than replacement. If your system is twelve or more years old, uses R-22 refrigerant, or has a failed evaporator coil, the math often favors AC Installation. We’ll show you the actual cost for both options on your specific unit, and let you decide. There’s no pressure either way.
How do I know if my AC needs a refrigerant recharge?
Your AC likely needs a recharge if it runs constantly without cooling the house, blows warm air, has ice on the copper lines or outdoor unit, or you hear a hissing sound near the indoor coil. These are all signs the system has lost refrigerant. The only way to know for certain is a pressure test with manifold gauges, which we do on every service call.
