Air Conditioning vs Open Windows

The weather is warming up in Wilmington, which means it’s time for the age-old debate: turn on the air conditioning or open the windows? With technology making central air conditioning more energy efficient, running your unit during the warm seasons doesn’t cost anything like it used to. However, getting some fresh air into your home also sounds appealing. Opening the windows also sounds like it would be the most cost efficient way to go. But is it really going to save you money?

Humid Air

Wilmington is located near the ocean, and during the warm seasons, the air gets rather humid. When you leave your windows open, you invite the humidity in. The average humidity level in Wilmington is in the mid-70s, although the mornings often start off in the high 80s. The longer you keep your windows open, the more likely you are to have moisture seep into your furniture and carpeting, which can be difficult to get out (leaving a musty smell over time).

Your air conditioner works not only to keep your home cool, it also works to dehumidify the air inside which, in turn, keeps your home comfortable. If you leave your windows open for any length of time, especially overnight, your air conditioner will need to work overtime to get rid of the excess humidity within your home, driving your energy bills sky high.

Cooling Your Home

Sure, if the weather is particularly nice out in Wilmington, you’re probably wondering what the point of leaving the A/C on all day is. Why not throw open the windows and enjoy the fresh breezes? Well, while the air might be nice when you first open the windows, the weather is likely to warm up, which will then start to turn your home into an oven. So, by the time you go to turn on your air conditioner, it will have to work extra hard to bring the inside temperature back to a comfortable number. All this overtime will not only increase your energy bills, it can also prematurely wear out your air conditioner, meaning repairs, or even replacement, before you are ready.

Keeping the Air Clean

Spring brings about so many beautiful things. Sunshine, flowers, trees getting their leaves back. It also brings about pollen and allergies. With the window open, the wind will undoubtedly carry these things into your home, and they will settle everywhere. Suddenly, your eyes are watery and you can’t stop sneezing, even if you dust and vacuum regularly. Your air conditioner comes with a filter, which prevents these things from entering your home, keeping your air cleaner, and allowing you to breathe easy.

Other Ways to Keep Your Home Cooler

Turning on your air conditioner in Wilmington doesn’t mean your energy bills are going to increase. Energy efficient units have seen to that. But there are also other things you can do throughout your home to help keep it cool, which will then keep you’re A/C from constantly running.

Set the temperature of your home to a comfortable level. There’s no need to turn it into an icebox. And when you’re away, or at night, you can set the temperature a few degrees higher. Programmable, smart, thermostats, provide customizable settings that let you stay in control. Use your ceiling fans to keep air circulating and close blinds or curtains to block the sun. If you have trees nearby, don’t chop them down, as they also provide valuable sun coverage. Keep unnecessary appliances that generate heat off, and run things like the dishwasher at night. With a little bit of planning, you can keep your Wilmington home cool and comfortable with the air conditioning on, without breaking the bank.

While opening the windows seems like a good idea, the climate in Wilmington tends to call for air conditioning.
