An AC unit should not be your sole line of defense against summer heat because an AC unit only cools your home down once it has already started to heat up.
Trusting only an AC unit to keep your home cool is similar to trying to keep wildlife out of your yard by chasing them out but doing nothing to prevent them from getting in. If you can prevent heat from getting into your home in the first place, you can reduce the workload on your AC unit and reduce your AC bills at the same time.
The Right Roof Makes a Difference
When choosing a roof for their home, many people focus solely on the initial cost of the roof. Asphalt shingles are one of the cheapest roofing materials around; thus, they often are the first choice. Initial cost, however, should only be one of your concerns. Asphalt absorbs UV rays from the sun and then reradiates them into your home in the form of heat. Simply by switching to a highly reflective and emissive metal roof, you can reduce your cooling costs by up to 40%. Replacing your roof with a more energy-efficient choice is a good place to start, but there is more you can do to keep your cooling costs down.
An Invisible Defense for Your Windows
Roofs are responsible for much of the solar heat gain in a home, but not all of it. UV rays that stream into your home through your windows can easily heat up the interior surfaces, and thus the air, of your home. If you want to keep your heating costs down, you need to block UV rays before they enter your home. While you could keep your blinds or curtains closed all the time, you can preserve your view by using a window film. A good window film can decrease your energy use by up to 23%.
The more you do to prevent sunlight from heating up your home in the first place, the less your AC system has to operate. The less your AC has to operate, the less wear and tear it is subjected to. Thus, less work means that your AC system should last longer and require fewer repairs.
As you can see, any good defense against the heat will incorporate multiple money-saving strategies. With a few upgrades to your home, you can decrease your cooling costs and reduce your AC maintenance and replacement costs.
