1. Use a programmable thermostat
- These are easy-to-use and essential for year-round energy savings. Tip: gradually lower the air temperature to keep your unit from working overtime when it doesn't need to; this will also prevent your fan from freezing.
2. Keep your thermostat away from heat (non-programmable)
- Try not to place lamps, TVs, or other heat-producing appliances near your thermostat. This will make the thermostat run longer than it actually needs to.
3. Keep your A/C unit in the shade
- Your machine will have an easier time cooling if the air around it is cool as well. This also helps your machine to run more efficiently. Be sure to keep plants and shrubs about 2 to 4 feet away to ensure proper air flow to/from the unit.
4. Weatherize your home
- Seal all air conditioning ducts and insulate ducts that run through unheated basements, crawl spaces, and attics. This keeps the cool air exactly where it’s supposed to be, inside!
5. Ceiling Fans
- If your home has ceiling fans, program them to run counterclockwise in the summer to push the air down. (If the upward angled side is rotating ahead, it will push air down. If the downward angled side is rotating ahead, it’s will lift the air up.)
6. Change your filters monthly
- Dirty filters kill you’re A/Cs efficiency. Replace or clean (if you’ve got the washable type) them every month. Check out your filter’s minimum efficiency reporting value – the higher the number, the better the filtration; and the more energy it needs to pull air through.
7. Avoid heating appliances
- Try to avoid using the oven, stove, dishwasher, or clothes dryer during the heat of the day. The heat produced by these appliances can dramatically increase the temperature in an area of your house.
8. Vents, vents, vents!
- Close vents in rooms that are not being used. Install vent deflectors if the air is not cooling the areas you’d like. Also, vacuum the vents as needed to keep the air flowing efficiently.
9. Change your furnace filters monthly (or switch to "Summer Mode")
- Many people forget about their furnace during the summer. If you’ve got central air and a ducted home, your furnace fan plays an essential part in blowing cool air through your house. Without proper maintenance, the cold air can freeze your furnace fan and increase your monthly payments.
10. Keep blinds and curtains closed
- We all love the natural light during the summer, but keeping your blinds open during hours of direct sunlight can have a negative impact on your A/C bill. Closing the blinds and curtains will keep your home from becoming a mini-greenhouse and can save you up to 7% on your bill.
11. Change the sheets
- It’s nice to freshen up a room with some new sheets, but it’s also a great way to keep cool. Flannels and fleece blankets are good for insulation in the winter, but are not ideal when summer time comes around. Cotton, on the other hand, is light and breathable – perfect for the warmer months.
12. Check your duct work
- If the ducts aren’t matching up correctly, or if one has a leak, you could end up cooling the inside of your walls instead of the inside of your rooms. We recommend having a professional inspect your duct work every 3-5 years.
13. Focus on you!
- How did our ancestors survive without air conditioning?! Regulating your internal temperature is just as effective as keeping the air on. Sip on some refreshing icy drinks and select cooler clothing options.
- If you have an older central air conditioner, consider replacing the outdoor compressor with a modern, high-efficiency unit. Just make sure that it is properly matched to the indoor unit.
