HVAC covers are not necessary. The outdoor portion is designed to withstand the elements. The cover helps reduce the effects of harsh sunlight, wind, flying debris and rain that can eventually cause a worn look. Please do not hesitate to reach out if you have any questions in the future, we are always here to help.
