Your air conditioning system is a sealed system there is nothing to service. The air handler if electric or the furnace if gas are also sealed bearing and fixed systems that require no maintenance. Rinse the fins top to bottom on your outside unit with a hose and keep your drains clean. 30 years experience heating and ac. Save the service money and get your next unit for free...
