Your AC is an important part of your home’s comfort. There are a few simple things you can do to help your AC keep its cool in summer and its warm appeal in winter.
1. Change Your Filter: Yeah, you’ve heard it before. A dirty filter will reduce your AC system’s efficiency because trapped dirt reduces airflow. A dirty filter can also affect indoor air quality. The job of an AC filter is to rap dirt before it builds up on your evaporator coil and cause it to fail. Be sure your filter is the right size (not too small) and that is MERV 6 value or higher efficiency rating.
2. Service Your System Annually: Every year, have a service tech clean the coil and drains, and check your system out. Many companies offer low rates for this service in the hopes of gaining you as a customer. Once a year, turn off the unit and spay the outside coils with a hose to remove dirt and leaves.
3. Check Your Ducts: Leaks in your ducts can reduce efficiency by 40% or more, causing your electric bill to soar. Many electric companies, including FPL, have a duct inspection and rebate program to repair or replace ducts. Seal leaky ducts and you can gain an up to extra half-ton of cooling and heating power from your AC.
4. Give Your Condenser Space: The outside part of your AC (the condenser) needs air to circulate around it to operate properly. Make sure it is not overgrown by bushes and that leaves are not clogging the vents.
5. Use Window Coverings: Heat-blocking drapes, curtains and shades reduce the load on your AC. Draw the drapes when you leave for work, and set the thermostat at 78 degrees. Drawing the drapes will keep the heat out, but during the winter leave them open. If your windows are leaky, keep the drapes pulled to keep the heat in when you are there. Weatherproofing windows and doors in one of the best ways to reduce your electric bills.
6. Keep Interior Doors Open: Your AC system is designed to work throughout your home. Closing doors to rooms you don’t use will not save money. It will throw your system off balance and make it more difficult for you to feel comfortable. Leave them open a foot or two.
7. Keep Your Thermostat Realistic: Lights, electrical appliances, etc. should not be near the thermostat because it can throw the gauge off. If your thermostat is in a hallway that is a lot cooler or hotter than the rest of your house, it will affect the accuracy of its readings.
8. Keep Registers And Vents Clear: Keep furniture, drapes and other objects away from registers and vents. Also do not close the vents completely in a room, for the same reason you shouldn’t close interior doors.
9. Don’t Be In A Hurry: Setting your thermostat really low will not help it cool more quickly, not will setting it high make it heat more quickly. It will use more energy. Just set the temperature you want and be patient. Generally, a 1600 sq. ft. home will reach the right temperature in less than an hour.
10. Use A Fireplace Screen: A lot of heat (and AC) goes up your chimney. Use a fire screen or insert to block airflow and cut down on electric costs. Keep the damper closed whenever you don’t have a fire.
