You’re no stranger to pool parties, ice cream trucks, and certainly not the heat of summer. However, if you’re anything like us and seek refuge in a nice cool house, then you’re familiar with the high electricity bills of the summer. Although it’s a must-have, there are some ways to curb your A/C cooling costs during the summer. Find ways to help reduce your electricity bill with these energy-saving tips
Selecting a Unit
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.
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, as well as 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.
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. Specifically, they should check to make sure the unit is operating properly, that no hoses or moving parts need to be replaced, and that no debris is obstructing the outside unit.
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 may be able to recoup the cost in just a few years in the form of reduced energy usage and lower utility bills.
Leaving the A/C running all day and all night is a guaranteed way to blow your utility bill budget for the month. You can avoid that by installing a programmable thermostat which allows you to vary the temperature according to your schedule. Set it to 78 degrees when you're home, for example. If you are gone for more than a few hours, it could make sense to set the air conditioning at 85 degrees while you're gone. Just remember not to go too extreme with temperature swings, as your unit will have to work that much harder to cool your home when you're ready to reduce the temperature.
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 and keep leaves, dirt, and other debris away from the base.
Plant shade trees and shrubs around your house to help reduce the heat of the sun, especially on the west and south sides. It can reduce your cooling costs by up to 30%. For more ideas see our blog on Energy Efficient Landscaping.
