air conditioner

Hot to stay cool during hot summer months

  • Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic
    • Whole-house fan are effective when operated at night and when the outside air is cooler than the inside
  • Set your thermostat as high as comfortably possible in the summer
    • The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be
  • Don’t set your thermostat at a colder setting than normal when you turn on your air conditioner
    • It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense
  • Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use
  • Don’t place lamps or TV sets near your air-conditioning thermostat
    • The air-conditioning thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary
  • Plant trees or shrubs to shade air conditioning units but not to block the airflow
    • Place your room air conditioner on the north side of the house
      • A room air conditioner operating in the shade uses as much as 10% less electricity than the same air conditioner operating in the sun
  • Add insulation and seal air leaks will help your energy performance in the summertime by keeping the cool air inside
  • If your air conditioner is old, consider purchasing a new, energy-efficient model

Maintaining your air conditioner

  • Check all hose connections for leaks
    • Repair leaks
  • Make sure the condensate tube is draining freely
  • Change or clean the furnace filter once a month
    • This is especially important during the summer when dust and allergens circulate
  • Clean the outside compressor by spraying it with a hose
  • Keep plantings at least one foot away for adequate airflow around the entire unit
  • Vacuum registers and air vents regularly
  • Have your ductwork professionally cleaned every few years
  • Keep furniture and drapes away from registers
  • During the winter, keep the compressor covered and remove window air conditioners
