Hi - I live in Chicago area where we can only wish about having more opportunities to use our air conditioner. I recently received conflicting advice and was wondering what y'all think.
One HVAC maintenance person suggested that covering the outdoor central air conditioning unit was recommended when not being used in the winter months because protecting it from the elements like rain/sleet/snow as much as possible would extend the life.
Then a different company showed and told me that covering the outdoor central air conditioning unit was not recommended because there is always some amount of condensation inside and covering the unit prevents this from evaporating and parts rust out sooner.
And of course, assume that I remember to remove the cover before starting the unit in the spring (I know that would cause damage).
