Air conditioning systems can either be an energy-efficient way to stay comfortable, or an air conditioner can cost a homeowner higher energy bills and leak refrigerant — both of which are not good for the environment. Make sure air conditioner maintenance for you and your HVAC technician is on your spring-cleaning checklist.

How important is air conditioner maintenance?

Air conditioner maintenance ensures optimal refrigerant charge, free air flow, good electrical-system function and clear drainage. Refrigerant charge and free air flow are key elements for energy-efficient heat exchange, minimizing stress on the compressor and limiting ice accumulation on the indoor evaporator coil.

A sound electrical system keeps the power flowing, of course, but it’s also important to ensure the compressor isn’t overworked. Clear drainage is important to prevent water damage to your home.

Technician’s checklist

  • Heat exchange (refrigerant): Your HVAC technician checks for refrigerant leaks at the coils and lines. The technician measures refrigerant, and charges to manufacturer specifications if needed.
  • Free air flow: The air filter is cleaned or replaced. Ductwork is visually inspected for leaks and damage. The air handler is cleaned and balanced if needed. Air flow across the air handler is measured.
  • Electrical components: Electrical contacts are inspected for wear. Thermostat and electronic sequences are checked.
  • Drainage: Drain line is inspected for wear and obstructions, including deposits, algae and interrupted slope or kinked line. Drain pan is inspected for mold and standing water, and cleaned.

Do-it-yourself checklist

  • Heat exchange (refrigerant): Wash the outdoor cabinet with a garden hose. Make sure you turn off the power first. Keep an eye on the indoor evaporator coil for ice accumulation.
  • Free air flow: Check the air filter regularly. Make sure the air-supply outlets are not obstructed by curtains or furnishings.
  • Electrical components: Consider installing a programmable thermostat for carefree energy savings and comfort.
  • Drainage: Check the drain pan the same time you change the filter and evaporator coil. If the drain pan is holding water or overflowing, turn off the air conditioner and call your HVAC technician.
