Cooling-system diagnosis

Refrigerant Leak Repair

Low cooling performance does not prove a refrigerant leak, and adding refrigerant without finding the cause may leave the underlying problem in place. Air Guide evaluates the cooling system, airflow, and refrigerant-circuit indicators before recommending leak-location, repair, or charging work.

Signs to notice

Which of these is your system doing?

Pick the closest one and we’ll carry it into your request. One symptom can have more than one cause, and an on-site assessment is what separates the possibilities.

The visit

What happens during refrigerant leak repair.

Manifold gauge hoses being connected to the service valves of an outdoor condensing unit

Rule out look-alike symptoms
Restricted airflow, control issues, and other equipment faults are considered before the problem is labeled a refrigerant leak.
Evaluate the sealed circuit
Operating indicators and accessible components guide the leak-location approach.
Define the repair decision
Leak location, component condition, equipment compatibility, and repair scope inform the available paths.
Repair and verify as applicable
Authorized sealed-system work and charging are followed by checks appropriate to the completed scope.

When to call

Do not wait for a small symptom to explain itself.

Request a diagnostic visit when cooling loss and ice recur, a prior refrigerant issue returns, or visible residue or unfamiliar sound suggests the sealed circuit deserves attention. Refrigerant work requires appropriate tools and handling; do not loosen fittings, puncture lines, or try a consumer sealant.

Avoids assuming every low-cooling symptom needs refrigerant
Focuses on locating and understanding the cause before repeated charging
Connects a leak finding to coil condition and replacement considerations
Keeps refrigerant handling out of unsafe do-it-yourself work

Why professional service matters

A decision grounded in what the system is doing.

Air Guide can place a suspected refrigerant leak in the context of the complete cooling system, including airflow, indoor coils, outdoor equipment, repair, and replacement options. The company serves residential and light commercial customers across Vancouver and Portland.

Refrigerant Leak Repair FAQ

Questions homeowners ask.

Clear answers for this service, without turning general guidance into a remote diagnosis.

Does low refrigerant always mean there is a leak?

A system should not be labeled low on refrigerant from indoor comfort alone. If testing confirms an insufficient charge, the installation history and sealed circuit should be considered so the reason can be understood.

Can refrigerant simply be added to restore cooling?

Charging may restore an operating condition only when it is part of a correctly diagnosed scope. If an active leak is left unaddressed, the symptom can return and the underlying repair decision remains unresolved.

Is a frozen evaporator coil proof of a refrigerant leak?

No. Restricted airflow, blower problems, coil condition, controls, and refrigerant issues can all contribute to freezing. The system should thaw safely and be evaluated before a cause is assigned.

Can I use a leak-sealing product in my air conditioner?

Do not add consumer chemicals or open the refrigerant circuit. The leak location, equipment condition, refrigerant type, and appropriate repair method should be established by qualified service personnel.
