Why 'Just Add Refrigerant' Doesn't Fix It

Refrigerant systems are sealed — refrigerant doesn't get "used up" like fuel.

Protocol Focus · Understanding Leaks

Refrigerant Systems Are Sealed — Low Charge Always Means a Leak

Unlike your car's gas tank, an AC's refrigerant charge is sealed at installation and should never need "topping off" — if your system is low, refrigerant is escaping somewhere and needs to be found.

Common leak points include line set connections, the evaporator coil, and the condenser coil.
We use electronic leak detectors and UV dye tracing to pinpoint the exact leak location.
Repairing the leak first means the recharge actually lasts.

Questions

Frequently Asked Questions

Why does my AC need refrigerant every year?

This means there's an active leak — refrigerant should never need regular top-offs in a properly sealed system.

How do you find a refrigerant leak?

We use electronic leak detectors and UV dye tracing to pinpoint the exact location, rather than guessing.

Is it bad for the environment to have a leak?

Yes, refrigerant leaks release greenhouse gases, which is another reason to repair rather than just recharge.

Can all refrigerant leaks be repaired?

Most can, though severely corroded coils sometimes need replacement rather than spot repair.

What refrigerant type does my system use?

Most systems installed since 2010 use R-410A; older systems may use R-22, which is being phased out and costs more to source.
