AC refrigerant leak repair Greenville SC explained
AC refrigerant leak repair Greenville SC is the process of finding and sealing the exact point where refrigerant escapes your system, then restoring the correct charge. Refrigerant does not get consumed like fuel; if your system is low, it leaked. We use a manifold gauge set to read pressures, an electronic leak detector and UV dye to pinpoint the breach, and a vacuum pump before recharging. Common leak sites include the evaporator coil, condenser coil, Schrader valves, and flare fittings.
Greenville summers push your AC hard from May through September, and that constant runtime exposes weak brazed joints and corroded coils. If your system uses older R-22 refrigerant, replacement is expensive, so finding and fixing the leak matters more than ever. Homeowners searching for refrigerant leak fix near me Greenville often wait too long and end up replacing a compressor. We also handle air conditioner refrigerant leak repair Greenville South Carolina for systems running R-410A and newer R-32 blends.
Why fix the leak instead of just recharging
Topping off refrigerant without repairing the leak is a temporary patch that costs more every season. Here is what a proper repair delivers for your Greenville home.
Lower cooling bills
A system low on refrigerant runs longer cycles and struggles to hit setpoint. After AC refrigerant leak repair Greenville SC, your unit reaches temperature faster and runs shorter cycles. Most customers see a noticeable drop in runtime within the first billing cycle.
Protect the compressor
Low refrigerant means poor oil return, and the compressor is the most expensive part in your system. Fixing the leak early prevents a compressor failure that can run $1,200 to $2,000. That is the difference between a repair and a full system replacement.
Restore real cooling
AC blowing warm air is the number one symptom of a leak. Once we complete Freon leak repair Greenville SC and recharge to factory spec, supply air temperatures drop back into the 55-60 degree range. You get cold air and a system that holds its charge.
Avoid repeat service calls
Paying for a recharge every spring adds up fast. A proper AC leak detection Greenville SC visit finds the source, and our repair holds. You stop calling us every season and start trusting your system again.
Our refrigerant leak repair process
We follow a fixed sequence on every call so nothing gets missed. Here is exactly what happens from the moment we arrive until we confirm the repair holds.
System assessment
We start by checking pressures with a manifold gauge set and measuring supply and return temperatures. Low suction pressure plus a high superheat reading points to a charge problem. We also inspect the air filter, blower motor, and contactor for related issues. This takes about 20 minutes.
Leak detection
Next we use an electronic leak detector and UV dye to trace the loss. We check the evaporator coil, condenser coil, line set, Schrader valves, and flare fittings. Most leaks show up at brazed joints or coil return bends. Finding the exact spot takes 30 to 60 minutes depending on access.
Repair and seal
Once located, we repair the leak. That may mean brazing a joint with a torch kit, replacing a Schrader valve with a nut driver set, or replacing a section of line with a tube cutter and flaring tool. Coil leaks may require a section replacement. We confirm the fix with a pressure test.
Vacuum and recharge
We pull a deep vacuum with a vacuum pump to remove moisture and air, then recharge by weight using a refrigerant recovery machine and scale. We use R-410A, R-32, or R-22 depending on your system. This step takes 45 to 90 minutes and is critical for longevity.
Verification and cleanup
Finally we run the system and recheck pressures, superheat, and supply air temperature. We confirm the charge holds and the leak is sealed. We clean up, replace the access panels, and walk you through what we found. Total visit time is usually two to four hours.
Local experience you can verify
Our technicians hold EPA Section 608 certification, which is required by federal law to handle refrigerants, and many carry NATE certification as well. We work on every major brand: Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Amana, Daikin, Mitsubishi Electric, Bryant, and Payne. We keep R-410A and R-22 on the truck and stock common parts like run capacitors, contactors, and condenser fan motors. That means most repairs finish in one visit, not two.
- EPA Section 608 certified to legally recover, handle, and recharge refrigerant
- NATE-certified technicians trained on Carrier, Trane, and Lennox systems
- Licensed under SC HVAC contractor license and Greenville County business license
- We carry R-410A, R-32, and R-22 to match older and newer systems
- Fully insured with OSHA safety certification on every job site
Why Greenville homeowners call us for leak repair
We are a local company, not a franchise. That means you talk to the same people who show up at your door. Here is what sets our AC refrigerant leak repair Greenville SC service apart.

Call before noon and we can usually be at your door the same day. We know a hot house is an emergency in Greenville, especially in July and August. Our schedule is built to absorb urgent calls.
Upfront pricing
You get a clear price before we start. No surprise charges, no pressure. If the repair is not worth it, we will tell you that too. We would rather earn your trust than sell you a repair you do not need.
We fix, not just recharge
Some companies only top off refrigerant. We find the leak and repair it. That is the difference between a temporary fix and a permanent one. Our refrigerant leak fix near me Greenville customers stay fixed.
Parts on the truck
We stock capacitors, contactors, fan motors, and common fittings. That means fewer return trips and faster completion. Most AC refrigerant leak repair near me Greenville SC jobs finish in a single visit.
What our refrigerant leak repair includes
Every leak repair visit includes the core steps below. If we find additional problems, like a failed capacitor or a clogged drain line, we will show you and price it before doing the work. No hidden add-ons.
What's Included
Full leak detection
We pressure test and use electronic detection plus UV dye on the entire sealed system. This covers the evaporator coil, condenser coil, line set, and all fittings. You get a written location of the leak.
Leak repair
We braze, replace, or seal the leaking component. That could be a Schrader valve, a flare fitting, a brazed joint, or a section of coil. We pressure test after the repair to confirm it holds.
Deep vacuum
We pull a vacuum to 500 microns or lower with a vacuum pump. This removes moisture and non-condensables that damage compressors and reduce efficiency. Skipping this step is why some repairs fail.
Refrigerant recharge
We weigh in the exact factory charge using a recovery machine and digital scale. We use R-410A, R-32, or R-22 as your system requires. No guessing, no overcharging.
Performance verification
We run the system and check superheat, subcooling, and supply air temperature. You get a report showing the system is holding charge and cooling properly before we leave.
Problems we solve for Greenville homeowners
A refrigerant leak shows up in predictable ways. Here are the most common complaints we hear and how we fix them.
AC blowing warm air
Your house gets hot and humid, and the system runs nonstop without cooling. This stresses the compressor and raises your power bill.
We check pressures first. Low suction pressure with high superheat confirms a charge loss. Then we find the leak, repair it, and recharge. Most customers feel cold air within an hour of the recharge.
AC losing refrigerant every season
You pay for a recharge every spring and the problem returns. That is money spent on refrigerant that leaks right back out.
This is the classic sign of an unrepaired leak. We perform AC leak detection Greenville SC with electronic tools and UV dye to find the source. Once repaired, the system holds its charge season after season.
Frozen evaporator coil
Ice builds on the indoor coil and blocks airflow. The system may run but not cool, and eventually the compressor can fail from liquid slugging.
Low refrigerant is a leading cause of a frozen evaporator coil. We thaw the coil, find and fix the leak, then verify airflow and charge. We also check the air filter and blower motor while we are there.
AC short cycling
The system turns on and off every few minutes. This wears out the contactor and compressor and never lets humidity drop.
Short cycling often traces to a low charge or a failing run capacitor. We test the capacitor with a multimeter, repair any leak, and recharge. If the contactor is pitted, we replace it.
When to call for refrigerant leak repair
Your AC runs all day but the house never gets below 78 degrees in July.
We check the charge first. If pressures are low, we run leak detection on the coil and line set. Once we repair the leak and recharge, we verify supply air temperature drops to 55-60 degrees.
You get your cool house back the same day, and the system holds its charge through the rest of the summer.
You notice ice on the indoor unit and the outdoor unit is making a hissing sound.
Hissing points to a leak on the high side. We thaw the coil, locate the leak with an electronic detector, and repair the line or fitting. Then we pull a vacuum and recharge by weight.
The ice stops forming, the hissing stops, and your system returns to normal cooling without the risk of compressor damage.
A technician told you last year the system was low and just added refrigerant.
That was a recharge, not a repair. We find the actual leak with UV dye and pressure testing, fix it, and recharge to factory spec. We also check for a failing run capacitor or contactor while we are there.
You stop paying for annual recharges. The leak is sealed and the system holds pressure, saving you money every season.
You are selling your home and the inspection report flags a refrigerant leak.
We provide a written leak location, perform the repair, and document the recharge with pressures and temperatures. That gives the buyer confidence the system is sound.
The sale moves forward without a repair credit, and you have documentation showing the system was properly repaired and charged.
Tools and methods we use
Tools & Equipment
Manifold gauge set
Reads high and low side pressures to diagnose charge level and calculate superheat and subcooling. This is the first tool on every call.
Electronic leak detector
Sniffs for refrigerant molecules at joints, valves, and coils. It finds leaks too small for soap bubbles to show.
Vacuum pump
Pulls the system down to 500 microns or lower to remove moisture and air before recharging. Skipping this step shortens compressor life.
Refrigerant recovery machine
Recovers refrigerant into a tank for proper disposal or reuse. Required by EPA regulations on every job.
UV dye and blacklight
Traces slow leaks that pressure testing misses. The dye glows at the leak point, confirming the exact location.
Torch kit and flaring tool
Used to braze joints and form flare fittings when replacing a section of line set or a leaking valve.
Multimeter and clamp meter
Tests capacitors, contactors, and motors for electrical faults that often accompany a low charge.
Methods & Techniques
EPA Section 608 compliance
Federal law requires certified technicians to handle refrigerants. We recover, recycle, and recharge according to EPA rules, and we document the charge amount on every job.
Pressure and temperature diagnosis
We compare suction and liquid line pressures against target superheat and subcooling. This tells us whether the system is low, overcharged, or has a restriction before we ever add refrigerant.
Nitrogen pressure test
After a repair, we pressurize the system with dry nitrogen and watch the gauge. A holding pressure confirms the leak is sealed before we pull a vacuum and recharge.
Weigh-in charging
We charge by weight using a digital scale, not by gauge guessing. This matches the factory nameplate charge and protects the compressor from overcharge or undercharge.
How refrigerant leak repair works in Greenville
Greenville's climate drives refrigerant leaks in specific ways. Summers run hot and humid from May through September, with outdoor temperatures regularly hitting the mid-90s. That means your AC runs long cycles, and long cycles expose weak brazed joints and corroded coil return bends. Older neighborhoods like North Main and Augusta Road have homes with original R-22 systems, where a leak means expensive refrigerant. Newer builds in Berea and Cherrydale often use R-410A or R-32, which are cheaper to recharge but still require a proper repair. We also see leaks after winter freezes when a line set expands and contracts. If you search for AC refrigerant leak repair near me Greenville SC in July, you are not alone. We prioritize same-day service during heat waves. Our trucks carry R-410A, R-32, and R-22, plus common capacitors and contactors, so most repairs finish in one visit. We work across Greenville County and know the building stock from Downtown to Paris Mountain.
Service Areas
Many downtown condos have rooftop or closet-mounted units with long line sets. Those line sets are common leak points, especially at flare fittings.
Older homes here often still run R-22 systems. We check for leaks carefully because R-22 replacement cost is high and a repair is almost always the better choice.
Berea has a mix of older and newer homes. We see more condenser coil leaks here from yard debris and pollen blocking airflow.
Homes at higher elevation see wider temperature swings. That expansion and contraction can loosen flare fittings over time.
Local Considerations
Long cooling season and high humidity
Systems run longer cycles, which stresses joints and coils. Leaks show up faster and more often than in cooler climates.
Older R-22 systems in established neighborhoods
R-22 is expensive and no longer produced. A leak repair is almost always cheaper than replacing the refrigerant charge repeatedly.
Pollen and yard debris
A clogged condenser coil raises head pressure and heat, which can accelerate corrosion and lead to leaks at the coil.
Winter freeze-thaw cycles
Expansion and contraction can loosen fittings and cause slow leaks that show up the following spring.
Warm air in August fixed
A homeowner in Nicholtown called because the house would not cool below 80 degrees. The system ran nonstop and the power bill had jumped $60. A previous company had added refrigerant twice in two years without finding the leak.
We found a leaking Schrader valve on the suction line, replaced it, pulled a vacuum, and recharged with R-410A by weight. Supply air dropped to 57 degrees and the system cycled normally. The homeowner has not needed a recharge since.
Maintenance & Follow-up
We recommended a spring tune-up each year to check pressures and clean the condenser coil. That catches small changes before they become big problems.
A West End homeowner noticed ice on the indoor unit and water on the floor. The system was short cycling and the air filter was clogged. Pressures showed a low charge and the evaporator coil was frozen solid.
We thawed the coil, found a leak at a brazed joint on the line set, and repaired it. After a deep vacuum and recharge, the system held pressure and cooled properly. The drain line was cleared and the filter replaced.
Maintenance & Follow-up
We set a reminder to change the filter every 60 days and check the drain pan tablets. Keeping airflow up prevents the coil from freezing again.
A North Main homeowner was told the system needed replacement because it used R-22 and was low on charge. The system was only 12 years old and otherwise in good shape. A leak test had never been performed.
We located a leak at a flare fitting on the liquid line, repaired it, and recharged with R-22. The repair cost a fraction of a new system and the unit is still running. Pressures and temperatures are within spec.
Maintenance & Follow-up
We check the flare fittings and pressures each spring. Catching a slow leak early keeps R-22 costs down and extends the life of the system.
What refrigerant leak repair costs
Typical 2026 pricing for AC refrigerant leak repair Greenville SC ranges from $250 to $1,200 depending on where the leak is and what refrigerant your system uses. A simple Schrader valve or flare fitting repair sits at the low end. An evaporator coil leak that requires section replacement sits at the high end. R-22 refrigerant costs significantly more per pound than R-410A, which affects the total. We give you a firm price before we start, and we never add refrigerant without repairing the leak first.
Pricing Factors
Leak location
An accessible flare fitting or Schrader valve is a quick fix. A leak buried in the evaporator coil or a line set inside a wall takes more labor and may require coil section replacement.
Refrigerant type
R-410A and R-32 are common and relatively affordable. R-22 is no longer produced and costs several times more per pound, which raises the total on older systems.
System charge size
A small system holds 4 to 6 pounds. A larger system can hold 10 to 15 pounds or more. The more refrigerant required, the higher the material cost.
Parts needed
A Schrader valve is inexpensive. A new line set section, a condenser fan motor, or a run capacitor adds to the parts total. We stock common parts to avoid a second trip.
Access and labor
A unit in an attic or a tight closet takes longer to access than one in a garage. Difficult access adds labor time but not parts cost.
Typical Investment Range
$250 - $1,200 depending on leak location and refrigerant type
Actual pricing varies based on project scope and requirements
Value You Receive
A repair at this price protects a compressor that costs $1,200 to $2,000 to replace. It also stops the cycle of paying for a recharge every season. For most Greenville homeowners, repairing the leak is the clear financial choice.

Call UsHow much does AC refrigerant leak repair cost in Greenville SC?
Most jobs run $250 to $1,200 in 2026, depending on where the leak is and what refrigerant you use. A Schrader valve or flare fitting repair is at the low end. An evaporator coil leak or an R-22 system sits at the high end. We give you a firm price before we start, and that price includes leak detection, repair, vacuum, and recharge.
How do I know if my AC has a Freon leak in Greenville?
The clearest signs are warm air from the vents, ice on the indoor coil, and a system that runs constantly without reaching setpoint. A hissing or bubbling sound near the line set also points to a leak. If a technician has added refrigerant more than once, you have a leak. We confirm with pressure testing and an electronic detector.
Can you fix a refrigerant leak same day in Greenville South Carolina?
Yes, in most cases. Call before noon and we can usually be there the same day. We carry R-410A, R-32, and R-22 on the truck, plus common valves and fittings. A typical repair takes two to four hours from arrival to completion. If a special part is needed, we will tell you upfront and schedule the return visit.
Why does my AC keep losing refrigerant in Greenville?
Refrigerant does not wear out or get consumed. If your system is low, it has a leak. Common spots are Schrader valves, flare fittings, brazed joints, and coil return bends. Greenville's long cooling season and temperature swings stress those points. A proper AC leak detection Greenville SC visit finds the source so you stop paying for recharges.

Customer Reviews
Our AC was blowing warm air in the middle of July. They found a leak at the evaporator coil, repaired it, and recharged the same day. The house was cool by dinner. Price was exactly what they quoted. Highly recommend for anyone in Greenville with a refrigerant leak.
I had two other companies just add refrigerant without finding the leak. These guys used a detector and found a bad Schrader valve in about 30 minutes. Fixed it, pulled a vacuum, and recharged. No more topping off every spring. Worth every penny.
Professional from start to finish. They explained the leak location, showed me the dye trace, and gave me a clear price before starting. The repair has held for two seasons now. I appreciate that they fix the problem instead of just recharging.
