No. If you have an air conditioner in your home that has a much higher capacity for cooling than your home requires, the unit will turn on, cool your home quickly, then turn off. Once the temperature raises, it will turn back on again. This constant cycle of starting up and shutting down use the most energy. Therefore, it is most beneficial to have a unit size appropriate for your home and needs. A unit that runs longer and more consistently uses less energy. A perfect example of this is your vehicle gas mileage. You use more gas driving around the city, because there is more stop and go. Less gas is used on the highway, because you are driving at a more consistent speed.
Should I just buy the largest air conditioner I can find and afford?
High efficiency appliances are always a bit more expensive, but generally speaking, they cost less to run. A high efficiency air conditioner, if properly installed and maintained, could save you up to 50% of your cooling cost.
Is it better to get a high efficiency air conditioner?
The purpose of a filter is to remove, dust, debris and other unwanted materials from your air. This also helps to keep the inside of your ductwork free from buildup. It is very important to check/change your filter frequently, especially during heavy use. If the filter is clogged and needs to be replaced, it will bog down your air conditioner and force it to work harder. When your air conditioner is working too hard, it uses more energy, and drives your energy cost up.
Why do air conditioners need filters?
Generally speaking, the energy costs of cooling a home are higher than the cost to heat. However, there are many variables, such as how you power your heating and cooling, and what electric/gas rates are at any given time. It is best to make sure that your home is as energy efficient as possible to gain the most benefits and savings on utility bills.
Does it cost more to heat or cool my home?
Air conditioners perform two functions, to cool the air in your home and to remove humidity. Warm air is drawn from your home into the air conditioner. It passes through a filter, then a cooling coil, and the result is dehumidified cool air returning back into your home.
