What you should know before you buy a new air conditioning unit.
When considering purchasing a new air conditioner for your home, you should know that today’s best air conditioners use 30% to 50% less energy to produce the same amount of cooling as air conditioners from the mid 1970’s.
Even if your air conditioner is only 10 years old, you may be able to save up to 20% to 40% of your cooling energy costs by replacing it with a newer and more efficient model.
An air conditioners efficiency, performance, durability, and initial cost depends on matching its size to the following factors:
- The size of your home and the number of windows it has.
- The amount of shade on your home windows, walls, and roof.
- How much insulation is in the ceilings and walls of your home.
- The amount of air that leaks into your home from outside.
- The amount of heat the appliances and occupants in your home generate.
Know that a larger air conditioner does not always provide the best cooling. Buying an oversized air conditioner will only serve the following consequences:
It costs more to buy a larger air conditioner. The larger than necessary air conditioner will cycle on and off more frequently which will reduce its efficiency. Frequent cycling makes indoor temperatures change more and results in less than comfortable environment. Frequent cycling also reduces moisture removal which is critical for comfort. An over sized air conditioner will drop the indoor temperature quickly satisfying the thermostat, however the system will not run long enough to remove the moisture to a normal range of 50% relative humidity, leaving the inside of the home cold and damp. (A very uncomfortable feeling.)
This cycling also wears out electrical parts and the compressor more rapidly. A larger air conditioner will use more electricity and create added demands on electrical generation and delivery systems.
