Chances are that if you've neglected a spring checkup, your air conditioner isn't cooling nearly as well as it could. A year's worth of dirt and debris clogging the cooling fins, a low coolant level, a dirty blower fan filter and a number of other simple problems can significantly reduce the efficiency of your ac condenser and wear it out faster.
You can't do everything; only a pro can check the coolant level.An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.
