Air conditioner tips for the summer

Call a professional: Each central air conditioner unit should be inspected, cleaned and tuned by a  professional. A professional tune-up typically costs between $89 and  $125.

Keep the filter clean: Clean and replace the  air conditioner filter frequently (check the filter once a month). This  is especially important during the summer when dust and allergens  circulate. If the filter becomes clogged, your system will have to work  harder to supply the same amount of cool air.

Made in the shade: Air conditioners with proper  shading can be more efficient. Air in a shaded space is cooler than the  surrounding air, meaning the A/C will have an easier time cooling the  air.

Don’t take the heat: Don’t place lamps, TV  sets, or other heat producing appliances near your thermostat. The  thermostat senses the heat causing the air conditioner to run longer  than necessary.

Dial for dollars: Remember that each degree you  dial below 78 increases your energy consumption by about 8 percent. If  your monthly electric bill is about $100, you’ll save $8 a month with  EACH degree you can stand above 78.

Set and go: If it’s hard to remember to tweak  your thermostat before you leave for work, consider investing in a  programmable thermostat or a timer for your window unit.

Time to replace? You may find your old air  conditioner is no longer efficient. Consider replacing your unit with an  Energy Star@ energy-efficient model. They’re usually more expensive but thanks to  federal tax credits and competitive prices, the prices are falling, and  because they use less energy, you save in the long-run, too. When  replacing your A/C, look for a properly sized unit. If you install a  unit that is too large, it will cycle on and off – reducing the  efficiency of the system.

Don’t cool the whole neighborhood: Seal air leaks with caulking and weather-stripping. Add insulation around air conditioning ducts.

Feel the breeze: If your home has ceiling fans,  switch your ceiling fan to run counterclockwise in the summer. That  will push the cool air down. You can run a ceiling fan half the day for  about $1.50 a month, compared to $25 for an air conditioner.

Watch the pavement: Avoid landscaping with lots of  rock, cement, or asphalt on the south or west sides of your home. If  it’s not shaded it will increase the temperature around the house and  radiate heat.

Free from debris: Keep plants, shrubs, and other landscaping about two to four feet away from your outdoor unit to ensure adequate airflow.

Install window film: A great home improvement  idea is to install home window film or tint to the insides of your  windows. Not only can it help keep your house cooler in the summer, but  also warmer in the winter.
