ANNUAL MAINTENANCE

• For an air conditioning system that is operated on a regular basis, cleaning and maintenance of the indoor/outdoor units are
strongly recommended.
As a general rule, if an indoor unit is operated for about 8 hours daily, the indoor/outdoor units will need to be cleaned at
least once every 3 months. This cleaning and maintenance should be carried out by a qualified service person.
Failure to clean the indoor/outdoor units regularly will result in poor performance, icing, water leaking and even compressor
failure.
