  1. Dave Rongey says:

    Hi Dave,
    Unless specifically required in our local area, an outdoor HVAC unit only requires a standard type circuit breaker, and does not require GFCI or AFCI type protection. However a 120volt service outlet near the HVAC unit should be on a separate circuit and have GFCI protection.
    I hope this helps,

  2. Dave Thompson says:

    Does the breaker for a mini split outdoor unit need to be GFCI and does it also need arc fault AFCI?
