About SplitFix

SplitFix publishes error code guides and diagnostic walkthroughs for mini-split AC systems. Our guides are written to help homeowners understand what a fault code actually means, identify what they can check and fix themselves, and know when a licensed HVAC technician is required.

SplitFix is operated by Atlas Edge Group. We don't accept paid content or manufacturer advertising.

As an Amazon Associate, SplitFix earns from qualifying purchases. Affiliate links are used to recommend relevant parts and tools; they don't influence our diagnostic guidance.
