FAQs

A: This points to a reversing valve problem or refrigerant issue specific to cooling mode. DC systems switch modes more frequently than most — the reversing valve wears faster here. We test both modes separately.

A: Not necessarily. Most common repairs — capacitor, refrigerant, contactor — cost similarly. Reversing valve replacement is more involved but still repair-worthy in most Diamond Bar cases.
