The Truth Will Keep You Cool: AC Myths You Need To Know This Summer

Construction & Contractors Articles

With summer sneaking in and bringing warmer days, you're likely to find yourself reaching for the air conditioning thermostat before long. Despite the fact that central air has become a staple in homes, there are still many myths circulating about how to make effective use of them. Here's a look at some of the most common myths you may have heard and the truth behind them.

Myth: Crank up the temperature on your AC when you go out to cut your energy costs.

Truth: It's often said if you increase the temperature on your air conditioning thermostat when you go out, your air conditioner won't work as much, so your energy costs will be lower. It's true that increasing the temperature on your thermostat will save you money, but raising the temperature too much might actually cost you more in the long run.

If you're going to be out for eight hours or more, the U.S. Department of Energy recommends you increase the temperature by ten to fifteen degrees at the most. According to their studies, you'll save as much as a percent off your energy bills for every degree you increase the temperature over an eight hour period.

If you raise it more than that, or you increase it when you're only gone for a couple of hours, you're going to increase your energy costs over time. This is because your air conditioner will spend more time balancing temperatures between the high and low settings as you go in and out during the day. The more consistent the temperature, the more energy savings you're likely to see.

Myth: Buying the largest air conditioner you can find will keep your house cooler.

Truth: Although it may seem like buying a larger air conditioner will make it easier to keep your home cool, the truth is that buying a system too large for your home could cause it to struggle with balancing the temperature in your house. It might drop the temperature too much or turn on and off frequently trying to balance the temperature.

For the best results from an air conditioning system, you want to choose a system sized properly according to your home's floor plan and square footage. Talk with an HVAC contractor who can help you evaluate your house and choose the best air conditioning unit for your needs.

Myth: Running ceiling fans all the time cuts your energy costs by keeping your home cooler.

Truth: Ceiling fans don't actually affect the way your air conditioner cools the house. In fact, ceiling fans don't physically cool the room at all. The air movement caused by ceiling fans makes the room feel more comfortable to you by creating a breeze, but it doesn't actually change the temperature of the room. If you're not home, it doesn't do you any good to have your ceiling fans running – it just costs you money.

Myth: Dropping your thermostat temperature cools your house faster.

Truth: Although you might think your house cools off faster when you drop the temperature on the thermostat by another ten degrees, the truth is your air conditioner can only produce a certain amount of air. The system runs, producing a specific amount of cool air according to the compressor's function, and then it shuts off automatically when the programmed temperature is reached. So, not only does it not make things cool down faster, you may actually use more energy by cooling your home more than you intended before you adjust the temperature again.

As you can see, there are several myths you need to consider when it comes to keeping things cool and comfortable during the summer. With the information presented here, you'll be able to maximize your use of air conditioning without costing yourself more in energy consumption. Contact an air conditioning service for additional information on how to set and run your specific unit for the size of your home.

inspecting the roof on your home

When was the last time you really looked at your roof? I had no idea how important yearly inspections of my roof was until I found myself footing the bill for a full roof replacement and interior ceiling replacement. Since then, I have learned how to inspect my own roof twice each year. I always inspect it each spring after the harsh winter elements have gone away and again in the fall before winter weather sets in. You can use the information compiled on my website to inspect the roof on your home and make the small repairs that will save you from full roof replacement.
