RETKNO Consulting

RETKNO Consulting operates from North Hollywood, serving the greater San Fernando Valley and surrounding Los Angeles neighborhoods. The business holds a perfect 5-star rating derived from a single client review, indicating strong customer satisfaction despite the limited sample size. Service availability spans standard weekday hours with Saturday appointments, providing flexibility for residential scheduling needs.

This contractor specializes in HERS (Home Energy Rating System) clearances, a niche service required for new construction and accessory dwelling units to verify energy efficiency compliance. The focus on energy ratings rather than general HVAC installation or repair positions RETKNO Consulting as a specialized provider for builders, property developers, and homeowners undertaking ADU projects who require official clearance documentation.
