Install a whole house ventilating fan in your attic or in an upstairs window to help air circulate in your home. Although not a replacement for a central air conditioning system, a fan is an effective way to stay comfortable on milder days.
Set your thermostat at 25 degrees Celsius, which is a reasonably comfortable and energy efficient indoor temperature.
Avoid setting your thermostat at a colder temperature 20 Cooling Systems than normal when you turn your air conditioner on. This is to eliminate long cooling periods as it will cool
to a lower temperature than you need and use more energy.
Consider using a ceiling fan with your window air conditioner to spread the cooled air to other rooms. But be sure the air conditioner is large enough to cool the additional space.
Don’t place lamps or television sets near your thermostat. Heat from these appliances is sensed by the thermostat and could cause your system to run longer than necessary.
Clean or replace air conditioning filters. Dirty air filters should be cleaned or replaced every month. Foam filters can be rinsed with water and wrung dry. Fiberglass filter needs to be replaced regularly.
No matter what kind of central air conditioning system you have, clean the outside condenser coil once a year. To clean, turn off the unit and spray coils with water at a low pressure. (High water pressure may bend the fins.)
Use duct tape to seal the cracks between each section of an air duct on your central conditioning or forced heating system.
