What our refrigerant leak repair includes
Every leak job is different, but here's what you can expect when we come out.
Work order
AC Refrigerant Leak Repair- Full system diagnosis: We check pressures, superheat, and subcool, then inspect the indoor and outdoor units. This tells us if the system is low and by how much. We also check for obvious signs like oil residue at fittings.
- Electronic leak detection: We use an electronic leak detector and UV dye to trace the loss. We check the evaporator coil, condenser coil, line set, flare fittings, and Schrader valves. We don't stop until we find the source.
- Leak repair or component replacement: Depending on what we find, we repair the joint, replace the valve, or swap the coil. We use a recovery machine to capture refrigerant before opening the system, then braze or flare the new part in.
- Deep vacuum and recharge: We pull a vacuum with a vacuum pump and hold it to confirm the system is sealed. Then we recharge with R-410A or R-32 to the exact weight on the data plate. We verify pressures and temperatures before we leave.
- Performance verification: We run the system and check the temperature split across the evaporator coil and the compressor amp draw. You get a summary of the readings and what we repaired. We also clean up and haul away old parts.

AC refrigerant leak repair Greenville TX: what it involves
A refrigerant leak never fixes itself. Topping off the charge buys you a few weeks and risks the compressor. We find the leak, repair it, and recharge to spec so your system holds.
AC refrigerant leak repair Greenville TX means finding the exact spot where refrigerant escapes, repairing it, and restoring the system's charge so it cools again. Refrigerant doesn't get used up like fuel; if you're low, it leaked. We pressure-test with nitrogen, scan coils and line sets with an electronic leak detector, and check Schrader valves and flare fittings. Once we isolate the leak, we repair or replace the failed component, pull a vacuum with a vacuum pump, and recharge to the manufacturer's spec.
In Greenville, TX, summer heat pushes systems hard from May through September, and that stress exposes weak joints and pitted coils. Older homes near Downtown and West End often have original line sets that have rubbed through insulation. If your AC is blowing warm air or the evaporator coil ices over, don't just top it off. A proper AC Freon leak repair Greenville TX job fixes the cause. We also serve Hunt County and the 75401 and 75402 ZIP codes.

How our refrigerant leak repair process works
No guesswork, no upsell. Here's exactly what happens from the moment you call until your system is cooling again.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Sniffs out refrigerant leaks at fittings, coils, and line sets. It's more accurate than soap bubbles for small, slow leaks.
Pulls a deep vacuum after a repair to remove moisture and air. We hold the vacuum to prove the system is sealed before recharging.
Captures refrigerant before we open the system for a coil or line set repair. It keeps the refrigerant out of the atmosphere and lets us reuse it.
Measures compressor and fan motor amp draw. After a repair, we compare it to the data plate to confirm the compressor is running within spec.
When to call for refrigerant leak repair
Your AC runs all day but the house won't drop below 78 degrees in July.
We diagnose the charge and look for leaks. If we find one, we repair it and recharge the system.
HomesYou've had refrigerant added twice in two years and it keeps getting low.
Topping off without repairing the leak is a losing game.
HomesThe evaporator coil is frozen solid and you see water on the floor.
We shut the system down, thaw the coil, and find the leak causing the low pressure.
HomesYou hear a hissing sound near the outdoor unit and the AC isn't cooling.
That hiss is likely refrigerant escaping.

How refrigerant leak repair runs in Greenville
Greenville summers are brutal on AC systems. From June through September, we see a spike in refrigerant leak calls, especially in older homes near Downtown and West End where original line sets have been rubbing against framing for decades. The clay soil also shifts, which can stress buried line sets.
Downtown Greenville
Many homes here are 40 to 60 years old with original copper line sets. We often find leaks where the line passes through walls or sits against ductwork.
West End
A mix of older bungalows and newer builds. Older homes tend to have R-22 systems, so we check for compatible refrigerants and line set condition.
Paris Mountain
Larger lots and longer line set runs. We see leaks at flare fittings and where lines are exposed to sun and temperature swings.

PhotoEvaporator coil leak in Downtown bungalow
Before: A 1950s home near Downtown Greenville had an AC that ran constantly but couldn't cool below 80. The evaporator coil was frozen, and the system was low on R-410A. The homeowner had been topping off refrigerant every spring.
After: We found a leak at the evaporator coil, replaced it, pulled a vacuum, and recharged to spec. The temperature split went from 8 degrees to 20 degrees, and the system now cycles normally instead of running nonstop.
Flare fitting leak on Paris Mountain
Before: A homeowner on Paris Mountain heard a hissing sound near the outdoor unit and noticed the AC wasn't cooling. The system was two pounds low on refrigerant, and the flare fitting at the line set was loose and leaking.
After: We tightened and resealed the flare fitting, pulled a vacuum, and recharged the system. The hissing stopped, and the system held pressure. The homeowner cancelled their annual top-off appointment.
Schrader valve leak in West End rental
Before: A property manager in West End had a tenant complaining of warm air. The system was low on charge, and a Schrader valve on the suction line was leaking. The tenant had been using a window unit to stay cool.
After: We replaced the Schrader valve, evacuated the system, and recharged with R-410A. The AC cooled the unit to 72 degrees within an hour. The tenant stopped using the window unit, and the property manager got a full report with photos.
Problems we solve with refrigerant leak repair
A refrigerant leak doesn't fix itself, and topping off is a temporary patch. Here are the problems we solve for Greenville homeowners and businesses.
AC blowing warm air
Your house gets hot and humid, and the system runs constantly without cooling. This stresses the compressor and raises your electric bill.
Evaporator coil freezing over
Ice blocks airflow and insulates the coil, so the system can't cool. If ignored, it can flood the drain pan and damage your ceiling.
Short cycling and high bills
The system turns on and off every few minutes, wearing out the compressor and contactor. Your energy bill climbs while comfort drops.
Hissing or bubbling at the unit
That sound is refrigerant escaping. It won't stop on its own, and the system will slowly lose capacity until it stops cooling.
Why fix the leak instead of topping off
Adding refrigerant without repairing the leak is a temporary patch that costs you more every season. Here's what a proper repair gets you.
Lower energy bills
Once we repair the leak and recharge to spec, your AC pulls the temperature down faster and shuts off.
Protects the compressor
The compressor is the most expensive part in your system. Running it low on refrigerant starves it of lubrication and causes it to overheat.
Restores real cooling
If your AC is running but not cooling, a leak is a top suspect.
Same-day service available
We know a broken AC in a Texas summer is an emergency.
What refrigerant leak repair costs
A simple Schrader valve or flare fitting repair is on the low end. A leaking evaporator coil that needs replacement is on the higher end.

What Greenville customers say
Our AC was running nonstop but the house stayed at 78. Greenville CoolCraft came out the same day, found a leak at the evaporator coil, and had it repaired by afternoon. They showed me the pressure readings before and after. Cold air again, and the bill was exactly what they quoted.
We'd had another company add Freon twice in two years. CoolCraft actually found the leak with a detector and fixed the flare fitting. It's been holding pressure for months now. I wish we'd called them first instead of paying for top-offs.
I manage several rental units in Greenville. When a tenant's AC quit cooling, CoolCraft diagnosed a refrigerant leak and repaired it the same day. They documented everything and sent photos. That kind of record-keeping makes my job easier.

(903( 304-5500Refrigerant leaks in Greenville TX usually come from vibration, corrosion, or worn fittings. The most common spots are the evaporator coil, flare nuts at the outdoor unit, Schrader valves, and line sets that rub against framing. In older homes, original copper lines develop pinhole leaks over time. We pressure-test and use an electronic leak detector to pinpoint the source before recommending a repair.
A simple Schrader valve or flare fitting repair is on the low end. A leaking evaporator coil that needs replacement is on the higher end. We give you a flat price before we start, and we don't charge a diagnostic fee if you approve the repair.
Yes. A refrigerant leak is one of the top reasons an AC runs but doesn't cool in Greenville TX. When the charge drops, the system can't absorb enough heat from your home. You'll notice warm air from the vents and longer run times. If the leak is slow, you might get cooling for a few weeks after a top-off, then it fades. Fixing the leak restores full capacity.
Greenville CoolCraft repairs AC Freon leaks for homeowners and businesses across Greenville and Hunt County. We handle everything from Schrader valve replacements to evaporator coil swaps. Call (903) 304-5500 for same-day service or to schedule a leak inspection.
