Air Conditioning Maintenance Checklist

Maintenance Checklist: Indoor

Program your thermostat to prepare for the season.   For optimal energy efficiency while keeping you comfortable, 24/7, it is advisable to always set your air conditioning temperature to 20° C in summer and 23° C in winter.

Cleaning HVAC filters. Once monthly, your central AC or heat pump filter should be cleaned or replaced—depending on the type. Dirty filters reduce performance and increase energy costs.

Keep clutter away from your HVAC unit. Storing items near your central air conditioner or heat pump equipment is a fire hazard, and may obstruct combustion air supply and lead to dangerous carbon monoxide production.

Remove obstructions from registers and return air grilles. When furniture, pet hair and dust buildup are blocking parts of your ventilation system, performance and efficiency suffer.

Have your system inspected and serviced twice annually. Homeowners who live in climates requiring year-round air conditioner use should invest in servicing the units prior to heating and cooling seasons. An air conditioner specialist should include the following during their maintenance visit:

  • * Tightening electrical connections and measuring voltage. Faulty connections are dangerous and can reduce equipment life.
  • * Lubricating moving parts. When equipment is lubricated, there is less motor friction, which improves system efficiency and reduces wear and tear.
  • * Inspecting condensate drains during cooling season. Clogged drains can adversely impact indoor humidity and may cause interior damage if water continues to build up.
  • * Cleaning coils. Over time, the coils on your condenser and evaporator can become covered in dirt and debris. This causes equipment to work harder to achieve indoor temperatures.
  • * Maintaining refrigerant levels during cooling season. Too much or too little Freon can adversely impact equipment while decreasing system efficiency.
  • * Checking airflow and ventilation functionality. Proper airflow increases comfort and lowers energy use.

Maintenance Checklist: Outdoor

Trim shrubs and brush away from outdoor units. Overgrown plants can obstruct your outdoor unit, forcing it to work harder while increasing utility bills. Keep trash and greenery away from the unit to optimize performance.

Clean outdoor coils. These coils can become clogged with grass clippings and dirt. Outdoor debris can generally be removed with a running water hose.
