Ductless AC Units. Cut Your Cooling Costs With These Money-Saving Tips.
If you have central air conditioning or a window air conditioning unit, you can cut your electric bills significantly, especially in very warm climates, by following these energy-saving cooling tips this summer.
When buying a window air conditioning unit, more is not necessarily better. Base the size of the air conditioning unit on the size of the room, the other factors that affect the temperature in the room, such as how many windows it has and whether it faces south, north, etc. An air conditioning unit that is too big for the room will work harder and cost you more.
Ductless Central Air Units. The SEER Number.
When you're shopping for a central air conditioning system, make sure the SEER number (seasonal energy efficiency ratio) is 13 or better (14 in warmer climates). A less efficient system will cost you more to run. Look for an EER (energy efficiency ratio) of 11 or higher for room air conditioners. A high efficiency unit costs more, but if you live in a hot climate, it will pay for itself in a few years by reducing electricity bills.
A cooling system is one of the biggest energy guzzlers in your home (second only to your heating system, depending on where you live). If you have an old air conditioning system with a SEER rating of less than 8, it may be worthwhile to consider replacing it with a more energy efficient system. You should be able to recoup the cost in just a few years.
Install a programmable thermostat so you can vary the temperature according to when you're home. Set it to 78 degrees when you're home. If you'll be gone for more than a few hours, it makes sense to set the air conditioning at 85 degrees while you're gone. Perform regular maintenance on your air conditioning unit. Replace the filter monthly during the cooling season and have a professional service your system at the beginning of each cooling season.
Make sure your air conditioning condenser is located in a shady spot and has room to dispose of the heated air it removes from your house. Don't crowd it with shrubs or anything else.
Sealing up air leaks in your house will reduce your air conditioning costs as well as heating costs. Caulk or seal places where utilities come into your home (plumbing, electricity, dryer vents, etc.). Fill gaps around chimneys. Weatherstrip around drafty windows and doors.
Install energy efficient ceiling fans and run them on hot days. If it's just a little too warm for comfort, use the ceiling fan without air conditioning. If it's hot enough to require air conditioning, using the ceiling fans at the same time allows you to raise the temperature setting by five degrees, which will reduce your costs. Use the ceiling fan only when you're in the room, because running the fan doesn't actually lower the temperature. The moving air increases the amount of evaporation from your skin and helps cool you off.
