Clean Coils, Strong Performance

See the difference proper coil protection makes — cleaner coils, higher efficiency, and longer equipment life.

With HardGard CoilGards

Our Coil Gards shield coils from debris, impact, and harsh weather while allowing unrestricted airflow for optimal performance. The result is a cleaner, more efficient, and longer-lasting system that stays protected year-round.

Without Coil Protection

Over time, unprotected coils collect dirt, debris, and damage from weather and maintenance activity. This buildup restricts airflow, reduces efficiency, and shortens the lifespan of the HVAC unit — leading to costly repairs and downtime.
