Cutting Your Air Conditioning Costs

Cutting Your Air Conditioning Costs

At your home or business, energy costs are likely to be the biggest budget line item after taxes and mortgages. The energy costs are usually gathered into one cost consisting of your natural gas and electricity. If you don’t have any gas appliances, it is most likely just electric, though most households have at least one gas appliance. The biggest part of the cost mainly comes from electricity. Reducing your electrical output is a great way to reduce energy costs. The focus of your electrical reductions should be on the biggest cost drivers, one of them being the air conditioner. Your air conditioner drives up the cost very quickly, even when it’s only been on for a few hours. An air conditioner increases your energy costs due to the several different levels it works on. Air conditioners have to use electricity to intake, cool, and circulate the air. An air conditioner isn’t really one appliance; it’s more like three or four appliances. The energy use amounts to three or four appliances too. The best way to remedy this is to use your air conditioner less, but how?


The heat in your home during the summer is a result of the heat of the outside air, so you need to reduce thermal bridging as much as possible to reduce the amount of heat in your home. A thermal bridge is any surface allowing more heat to pass through than the surrounding areas. During the summer, thermal bridges allow outside heat into your home; during the summer, they allow the heat inside to escape. Overall, you need to reduce the bridging to reduce your costs. One way to do so is to add window roller shutters. Shutters will help reduce the amount of bridging you see since they provide an extra layer of insulation over your windows.

Heat passes from one place to another by exciting molecules and causing them to move. If you think of heat as movement and cold as a lack of movement, it’s easier to envision how shutters can help reduce thermal bridging. When air molecules get excited, they bump against other molecules, transferring their energy. The energy is then transferred to your windows and into your home. Sturdy shutters add another layer of protection against energy transferring. Furthermore, shutters deter a lot of heat exchange by blocking sunlight.

Too Much Sun

If your home is heating up during the summer, it might be due to the amount of sunlight entering your home. Sunlight has a way of heating the air as well as the furniture in your house; you would be surprised how effectively furniture acts as insulation. Your sofa can trap heat from the sun, becoming two or three degrees warmer than the air inside your home. Such a small increase might not seem like a lot until you think about how much different 22 degrees feels from 26. Such a difference is enough to make you turn on the air conditioner.
