The better your home shelters you from the summer heat, the less you have to worry about summer cooling costs. In other words, the key to getting the most efficiency from your AC system is to understand how heat enters your home and then improve your home's heat defenses. A good place to start heat proofing your home is by improving the heat resistance of your roof and windows.
Roofing and AC Costs
The part of your home that is most exposed to the sun is your roof. The sun beats down on your roof for the greater part of the the day. Some roofing materials, such as asphalt shingles, will absorb heat from the sun. In fact, shingles can get as hot as 150 degrees. Some of this heat transfers into your attic and from there into your home, which makes your AC unit's job that much harder. The key to choosing energy-efficient roofing is to look for roofing that is both reflective and emissive. Reflective roofing will repel the sun's heat, and emissive roofing will release what heat it does absorb back into the atmosphere. Metal roofing, for example, can decrease your cooling costs by up to 40%.
Windows and AC Costs
Windows do not absorb heat like a roof will, but they can, nonetheless, contribute to high cooling costs. The problem with windows is that they allow the sun's UV rays to streak right into your home. These UV rays will then heat up your walls, floors, and furniture. You could use blinds or curtains to block out the sun, but this deprives you of natural light and can cut off your view of the outside world. What you need is a way to filter out UV light while still allowing the sun to light up your home. A good low-e window film will reflect UV waves while still allowing you a view of the outside world. In this way window films can reduce your cooling bills by up to 23%.
These two examples should be enough to demonstrate that if you take steps to seal heat out of your home, you can save on coolings costs. An AC unit can help to keep your home cool, but on a hot day, heat gain can exceed your AC unit's capacity to keep your home cool, which means your home will continue to get warmer throughout the day even as your AC unit churns cool air into your home. Taking steps to reduce heat gain will make your AC unit's job easier and save you money.

So many of us make the mistake of assuming the air conditioning system is up and ready to go without having to do anything after a long winter. Unfortunately, oftentimes, this isn't the case. You know how I know that air conditioning systems need pre-summer maintenance? Well, I know because I broke my air conditioning unit trying to use it without even looking at it before starring it up for the first time. It was that moment that I learned a very valuable lesson the hard way. My blog will walk you through getting your air conditioner ready for summer without the expensive lesson that I had to learn.
