Pittsburgh – – September 19, 2026 -- A Windsor, Ontario-based inventor has filed a patent-pending design for COOL SCREEN, a protective cover engineered to shield air conditioning units from weather exposure and debris clogs.

Design targets AC unit longevity and energy efficiency

The invention aims to reduce premature wear on outdoor AC units by blocking environmental debris that typically causes clogs and efficiency losses. By maintaining unobstructed airflow, the product could lower the energy costs tied to reduced compressor performance over time.
