Air conditioning is intended to keep your home comfortable during the hot summer months, but if you fall prey to some common air conditioning myths, you may not be getting the maximum benefits from your system. Here's a look at three air conditioning myths – and the real truth they are hiding!
Myth: The bigger the air conditioner, the better it will cool your home.
When homeowners are not sure which size air conditioner to purchase, they often just assume that bigger is better. This is unfortunately not the case. Air conditioners work not only by cooling air, but also removing humidity from the home. An air conditioner that's too large for your space will cool the space too quickly and then cycle off before it has a chance to remove enough humidity from the air. Thus, your home will continue to feel warmer than if you were to cool it with a smaller unit that ran for a longer time and removed more humidity. (Higher humidity makes a space feel warmer.) Not to mention, an oversized unit takes more power to run and will lead to higher energy bills.
If you are having a central air conditioning system installed, check to make sure the unit your HVAC technician is recommending is designed to suit the square footage of your home. When buying a window unit, measure your room, and then buy a unit that's advertised to cool a room that size. If you aren't sure which size to get, talk with a professional, like Tropic Air Conditioning INC, for more information.
Myth: Turning the air conditioner off at night and opening the windows will save energy.
It might be tempting to turn off the unit and open the windows on a cool night, but when you do this, you are re-introducing humidity to the air. This means your air conditioner will have to work harder to remove it when you turn it back on the next day. It's best to just leave your windows shut the entire time you're using your air conditioning system so that the humidity is kept outdoors.
Myth: If you turn the thermostat way down, the room will cool off faster.
Turning the thermostat way down won't make your home cool any faster. It will just cause the air conditioner to run for a longer period of time before shutting off. Just turn the thermostat to your desired temperature, and let the air conditioner do its work. If you are concerned that your home takes too long to cool, talk to your HVAC tech. Your air conditioner may need to have its coolant recharged or the filter replaced.
