Freon Leak Repair in Corpus Christi, TX
When refrigerant leaks from an AC system, the fix isn't just adding more refrigerant — it's finding where it's escaping and sealing that point. Leaks happen at fittings, valve cores, coil damage, or corroded line connections. Left unrepaired, a leaking system keeps losing refrigerant, damages the compressor from running low, and costs progressively more to maintain.

When to Call
When You Need Freon Leak Repair
- You've had refrigerant added more than once in the past two years
- A technician confirmed a leak but only topped off the system without fixing it
- You can smell something slightly sweet or oily near the indoor or outdoor unit
- There's an oily residue visible on refrigerant line connections or fittings
- The system cools well right after a recharge but declines within weeks or months
- Your compressor is making a labored sound — often a sign it's running low on charge
How It Works
Our Process for Freon Leak Repair
- 1
System Pressure Assessment
We hook up gauges first to confirm refrigerant is actually low and to understand how significant the loss is before we start searching for the source.
- 2
Electronic Leak Detection
We use an electronic leak detector to sweep common failure points — Schrader valves, flare fittings, the evaporator coil, and line set connections at both units.
- 3
UV Dye Check if Needed
If the electronic search doesn't pinpoint a single source, we check for existing UV dye in the system or add dye and run the unit to help trace the leak location.
- 4
Leak Location Confirmation
We confirm the leak point before quoting any repair. We won't guess or recommend a repair based on where leaks 'usually' happen — we find the actual source.
- 5
Repair Based on Location and Severity
Minor fitting leaks get tightened or resealed. Valve cores get replaced. Coil leaks are a bigger job — we'll explain what's involved and whether repair or replacement makes more sense given the unit's age.
- 6
Recharge and Verification
Once the leak is repaired, we recharge the system and verify pressures and performance. We also check the repair point again with the detector under operating pressure.
What's included
- Electronic leak detection sweep of all accessible components and fittings
- UV dye check or dye injection when electronic detection is inconclusive
- Repair of the confirmed leak point — fittings, valve cores, or accessible connections
- System recharge to manufacturer spec after repair is complete
- Post-repair leak verification with the detector under operating pressure
What's not included
- Evaporator or condenser coil replacement — major repairs quoted separately after diagnosis
- Line set replacement due to mechanical damage or corrosion along the run
- Warranty on repairs to coils with widespread pitting or corrosion damage
Real Situations
Common Scenarios in Corpus Christi
A homeowner near Padre Island has had the same system recharged three times in three seasons and wants to stop the cycle.
We do a proper leak search instead of another recharge. Coastal properties near the water see accelerated corrosion on evaporator coils — formicary corrosion from the combination of humidity, organic compounds, and copper is common. We locate the source, explain what repair involves, and give an honest assessment of whether the coil is worth fixing or whether replacement is the better path.
A homeowner's AC stopped cooling suddenly after a landscaper hit the refrigerant line with a trimmer.
Mechanical damage to the line set is straightforward to find but not always simple to repair depending on where it happened and how the line runs. We locate the damage, explain what a proper repair or line set section replacement involves, and get it done correctly so it holds.
An older home in the West Side has a unit from the mid-2000s that uses R-22 and has a slow leak.
We find the leak and explain the realistic options. R-22 is expensive and increasingly hard to source. Depending on leak severity and unit condition, continuing to repair and recharge may not be the most practical path. We give the homeowner the information to make a real decision — not a sales pitch for a new system.
Corpus Christi Context
Why this matters in Corpus Christi
The Gulf Coast environment is hard on copper refrigerant coils. Formicary corrosion — a specific type of copper pitting caused by humidity and organic compounds in the air — is more common here than in drier inland areas. Homes within a few miles of the bay or Gulf tend to show coil degradation faster than properties further inland, and it's worth factoring that into any repair-versus-replace conversation.
Straight Talk
About pricing & scope
Leak repair cost varies significantly depending on where the leak is. A Schrader valve core is a minor fix. An evaporator coil with widespread corrosion pitting is a major one. We'll tell you what we found and what the repair involves before any work starts. Sometimes the honest answer is that repair costs approach replacement costs, and you deserve to know that.
