As in most areas of home care, with seasonal maintenance services for your AC unit, you get what you pay for. A thorough seasonal tune-up will go a long way to keeping you unit running in top condition all through the hot months. It can help you avoid costly repairs as well. Getting a maintenance agreement is an excellent way to make certain your unit is thoroughly inspected. You might even get a break on the fee. A tune-up should include an inspection and test of the blower and fan assembly, condenser coil and evaporator coil, drive belts and pulleys, safety controls, electrical connections, heat exchangers, motors and all compartments. A technician can also provide written documentation of the inspection, which may come in handy if something needs attention down the road. A thorough inspection will feel worth the expense.
