  • Hose down the outdoor condenser every month.
  • Keep bushes, shrubs and pets away from outdoor units.
  • Replace air filters after 30 days.
  • Have a qualified technician service your air conditioner once a season.

    Air Filters
  • Fiberglass air filters are adequate for most homes.
  • HEPA (high-efficiency particulate air) filters are best for allergy sufferers and homes with pets.
  • HEPA filters can last 90 days. However, they must be monitored because dirty HEPA filters can put additional strain on the air conditioner.

  • Set temperatures higher during the day if nobody is home.
  • The hotter it gets inside during the day, the longer it takes to cool down again.
  • Programmable thermostats automatically adjust day and evening temperatures.
  • Recommended settings are 80 degrees when nobody is home, 74 - 76 degrees when home is occupied.

  • Check the circuit breaker first.
  • Always use a qualified service technician for repairs.
