Winterise AC Unit

When preparing for the winter months, first of all turn off the breaker/ remove the fuse associated to the Air Conditioner in the home (assuming it is a dedicated circuit) If not then inspect the outside unit and if there is a breaker installed adjacent to it then turn that off. Secondly then place a cover over the top of the outside unit to prevent snow and ice entering the cavity of the box ( I personally use a garbage bin lid held down with elastic straps but a wooden board held down with a large stone works). DO NOT wrap in a plastic bag or tarp as this will retain moisture inside the assembly and promote corrosion.
In the early summer when you are considering using the unit again turn the breaker back on and remove the cover approx 24 hours before you plan to use it, clean or change the main system filter for optimum efficiency.
