Refrigerant Leak Detection

Find the leak first. Then recharge. Never the other way around.

If your AC is low on refrigerant, there's a leak somewhere — refrigerant doesn't 'get used up.' Recharging without finding the leak is throwing money out the door. GERARDO HVAC LLC uses electronic leak detectors and pressure testing to locate leaks across Fort Dodge, Webster City, Humboldt, and Eagle Grove, Iowa.

Signs You Need Refrigerant Leak Detection

AC blows warm air after running for a while
Ice buildup on the refrigerant line or evaporator coil
Hissing sound near the indoor or outdoor unit
Oily residue around fittings or coil ends
AC needs to be 'topped off' every season
Long run times with poor cooling

How I Approach Refrigerant Leak Detection

I pressure-test the system, use an electronic refrigerant leak detector, and inspect the most common leak points — Schrader valves, coil U-bends, line-set flares, and brazed joints. If the leak is in the coil, I'll explain whether repair, coil replacement, or system replacement is the right call.

What's Included

Electronic leak detection (R-410A, R-22, R-32, R-454B)
Pressure testing with nitrogen
Evaporator and condenser coil inspection
Line-set, valve, and fitting inspection
Honest report on repairable vs. non-repairable leaks
Coordination with refrigerant recharge service

Why Choose GERARDO HVAC LLC

Some shops recharge without ever finding the leak. That's an EPA violation and it wastes your money. I find the leak first and tell you honestly whether it makes sense to repair, replace the coil, or replace the system.

Refrigerant Leak Detection — FAQs

How much does leak detection cost?

Less than recharging a leaking system twice. I quote the diagnostic before starting so you know what to expect.

What if the leak is in the coil?

Sometimes the coil is under warranty and only labor is owed. Sometimes coil replacement makes more sense than chasing a small leak. I give you the honest numbers either way.
