Most homes in hot countries have not yet purchased their first AC Air conditioning today is concentrated in a small number of countries, but AC sales are rising rapidly in emerging economies. Cooling is the fastest growing use of energy in buildings Without action to address energy efficiency, energy demand for space cooling will more than triple by — consuming as much electricity as all of China and India today. The problem is, today's consumers are not buying the most efficient ACs The average efficiency of air conditioners sold today is less than half of what is typically available on the shelves — and one third of best available technology.

Introducing the Efficient Cooling Scenario The Efficient Cooling Scenario describes an energy pathway based on strong policy action to limit energy needs for space cooling.

How to save on electric bill with an AC (simple tweaks and maintenance tips)

Baseline scenario Efficient Cooling Scenario Cooling will drive peak electricity demand, especially in hot countries More efficient ACs can reduce the need for new power plants to meet peak power demand, especially at night. 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 unnecessary expense.

Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home more effectively and remove more moisture from the air because of slower air movement through the cooling equipment. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air through your home without greatly increasing electricity use. Remember that efficient operation of any air conditioning system relies on a properly insulated and air sealed home. Skip to main content. Room Air Conditioners Energy Saver.

A room air conditioner is one solution to cooling part of a house. Sizing and Selecting a Room Air Conditioner The required cooling capacity for a room air conditioner depends on the size of the room being cooled -- room air conditioners generally have cooling capacities that range from 5, Btu per hour to 14, Btu per hour.

  • Check your ducts for air leaks. First, look for sections that should be joined, but have separated and then look for obvious holes, If you use tape to seal your ducts, avoid cloth-backed, rubber adhesive duct tape, which tends to fail quickly. We recommend other products to seal ducts: mastic, butyl tape, foil tape, or other heat-approved tapes. Remember that insulating ducts in the basement will make the basement colder.
