*Omniguard Total Corrosion Protection Technology is available on select units.

Depictions of corrosion are based on accelerated exterior/interior coil corrosion degradation; actual coil corrosion time frame may vary. Household items like paints, furniture, etc. emanate gaseous substances known as volatile organic compounds (VOC). VOCs are responsible for the new home smell and, when combined with moisture, can create organic acids that cause corrosion. Results are based on comparisons of standard copper tube and aluminum fin coils to an aluminum tube and aluminum fin coil constructed of specific alloys and indicate less corrosion over time. It does not alleviate 100% of corrosive effectives.
