These are examples to help explain the symptom. More than one fault can cause similar behaviour.

A fan, mounting or HVAC actuator may need attention.
Inspection confirms what your vehicle needs.
This information is general guidance, not a diagnosis or repair quote. All A/C concerns are subject to inspection and diagnosis. The required work and price can only be confirmed after assessment; none of the repairs listed above is guaranteed to be needed.
A regas does not repair a leak. If a leak is found, we discuss the required repair before recharging the system.
