I highly recommend each client ensure their condenser (the outside AC unit) is clear from debris, storage items and hedges. Lacking proper clearance space away from your air conditioner will cause a unit to work less efficiently and lead to unnecessary repairs due to added strain on the unit. I recommend keeping items/bushes/debris at least 18 inches from any side of your air conditioner. Lattice covers can help improve aesthetics if your system is an eyesore, however, be sure to it is located at the appropriate distance. Also, do not add any type of cover on top of your unit unless you are 100% sure it will not be running when the cover is in place.
