Operations of an Air Conditioner for your Indoor Comfort

As the cooling season is upon us we are pleased to offer energy savings and cooling tips for your indoor comfort.

• MG&E and Alliant Energy recommend setting thermostats at 78 degrees for cooling. We find most people set their thermostats between 75 and 78 degrees.
• Operating system during the day then turning unit off at night and opening windows will cost you more to operate. When you open windows you allow moisture to dampen carpet, furniture, beds, drapes and other items. 40% of the operation cost of A/C is to remove moisture. If you run A/C during the day keep windows closed at night.
• A properly designed system will drop indoor temperature by one to three degrees per hour. An oversized system that cools down to fast will not properly remove moisture. Your home will feel clammy. Air conditioners operate more efficiently the longer they run continuously, and are sized so they don’t turn on and off frequently.
• Do not use expensive pleated furnace air filters purchased from hardware stores. As they may restrict air flow. Use either the $1.00 standard air filter or purchase from a HVAC contractor a high efficiency spaceguard type filter for around $600.00.
• Furnace air filters are used for both heating and cooling. Check your filters monthly and replace if necessary.
• Do not place items which generate heat such as lamps, computers, TV, or fish tanks under the thermostat. If direct sunlight from windows hits your thermostat you may have to relocate the thermostat.
• We recommend constant fan operation to circulate, filter & mix the air.
• Close drapes on the sunny side of the house.
• Have your Carrier heating and cooling system checked by a Carrier dealer on a yearly base.
