Living in the northeastern part of the country, I wait a long time for summer. The winters typically linger for more than six months of the year. We often need to run the furnace during spring and fall. The weather is windy, chilly and wet the majority of the time. I am unwilling to invest into central air conditioning. It’s way too expensive to only use it for a few weeks. However, our short summers can be brutally hot and humid. While I try to be outside as often as possible, enjoying the blue skies and sunshine, I don’t want an overheated and sticky house. It’s especially important that my bedroom be nice and cool for sleeping. The ideal solution for my situation is window air conditioners. I was able to buy several cooling units for right around a hundred dollars each. They are lightweight enough that it’s easy for me to carry them up to the attic for storage in the winter and bring them back down in the late spring. It takes me a couple of minutes to install them into the windows. Despite the small size, the air conditioners are powerful enough to drop the room temperature very quickly. They include cordless remotes that allow temperature changes and adjustments to the fan speed without even getting out of bed. Not only are the window air conditioners energy efficient, only running them at night keeps costs very low. I sleep so much better with the air conditioner operating. The noise works to drown out the sounds of morning birds, road construction, traffic, neighbors and barking dogs. The filter helps to capture dust and other contaminants.
