Air conditioning systems require regular maintenance to keep them working at highest efficiency whether they are window units or central air conditioning systems.   

The inner components can collect dust, dirt, and mildew, which can lower their operating efficiency and your home's air quality. Check the manual that came with your unit and follow basic procedures to keep it working properly.   

Here are some ways to not only ensure top operating efficiency, but also to save energy costs this summer:  

Installation and Maintenance

• Make sure the air conditioner is installed at least two feet away from foliage and 10 feet away from your dryer's vent. Trim foliage and clean up nearby debris to minimize dirt near the condenser unit. If you have an outdoor unit for central air, do not surround it with shrubs or solid fencing. 
• Make sure your returns are free of any obstructions. 
• Make sure that all of your supply registers are open all the way. 
• Clean or replace your air conditioner filter every month during regular use. If you have dogs or cats indoors or if you live in a dusty area, you may need to change or clean the filters more frequently. 
• Be sure the drain line of your central air unit isn't clogged with mold and mildew, which can cause water to back up into the home. Pour a cup of bleach into the line's access hole each spring. If a clog occurs, place the nozzle of your wet/dry vacuum over the line's opening to suck it out. 
• Wipe off the housing when it becomes dirty and then remove it. Sweep any debris away from the inner components with a paintbrush. If the aluminum fins are bent, contact a repair person to adjust them. 
• Contact a service technician yearly to inspect the condenser and evaporator coils which may require chemical cleaning. The technician can also check the motor and electrical components to ensure that everything is functioning properly.

Setting the Thermostat

• Set your thermostat as high as comfortably possible. A setting of about 78 degrees F when you are home and need cooling is what is recommended.  
• At night if the outside temperature drops, raise the thermostat to a comfortable level or turn off the A/C and keep the windows open while sleeping. When you wake in the morning, shut the windows and blinds to capture the cool air. 
• A ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort! Be sure to turn off ceiling fans when you leave the room. Remember that fans cool people, not rooms, by creating a wind chill effect. 
• Avoid setting your thermostat at a colder setting than normal when you first turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and unnecessary expense. 
• Maintain a comfortable temperature and avoid lowering the setting on really hot and humid days; lowering the setting use more energy and cost more than leaving it at the temperature you actually want.

Other Helpful Hints

• Install window coverings to prevent heat gain through the windows.
• When you shower or take a bath, use the bathroom fan to remove the heat and humidity from your home. Your laundry room will also benefit from spot ventilation. Make sure bathroom and kitchen fans are vented to the outside (not just to the attic).
