My thermostat is equipped with a two position setting for the fan, "automatic" and "on". Where should I set it?
A: The two positions are usually used in conjunction with a central air cleaning system. The normal setting is on "automatic" and the fan's cycle will be controlled by the temperature in the room. However, if your home is equipped with an air cleaner (media or electronic) or you wish to keep a continuous flow of air, switch the setting to "on". Remember, cental air cleaning devices only work when the furnace is circulating air. If you wish to get the most from your air cleaner, you should keep the setting to "on".
I see the arrow on my furnace filter but I'm not sure how to correctly position it? What should I do?
A: The arrow should point in the same direction as the air flow. In most cases, it will point towards the furnace and should fit between the return air part of the system and the furnace. The filter screens out the dust and other impurities before the air is warmed in your furnace and then distributed through the duct system.
Set the Thermostat
A: The most economical operation of your system comes from setting the thermostat properly. Set the thermostat at the highest summer setting or the lowest winter setting at which you are comfortable. Typical settings are 78 degrees for summer cooling and 68 degrees for winter heating. When cooling, your operating costs increase from 3% to 8% for each degree your thermostat is lowered. When heating, your operating costs increase similarly for each degree your thermostat is raised.
Keep the Air Filter Clean
The easiest way to ensure your system operates efficiently and economically is by keeping the air filter clean. There are several types of air filters and several possible locations for the air filter. Ask your service technician next time he's out at your home to show you where your air filter is located and which type of filter to use. If you have allergies, you should look at a pleated allergy filter or a media or electronic style air cleaner.
Keep Doors and Windows Closed
Close all doors and windows to the outside. This will reduce the heating load in winter and the cooling load in summer. Your system will operate more economically as a result.
Keep Vents and Grilles Unobstructed
Arrange your furniture and drapes so that all ouput vents and intake grilles are free from obstruction. This will reduce the cooling and heating load on your system for more economical operation.
Avoid Excess Use of Exhaust Fans
Excessive use of kitchen or bathroom exhaust fans will make your system work harder. This will increase energy consumption and costs. Keep costs in check by making wise use of exhaust fans.
Control Direct Sunlight
Let the sun in during the winter. In winter, direct sunlight reduces the load on your heating system. Open window shades and awnings to increase direct sunlight and lower the heating load.
Keep Heat Away from the Thermostat
Make sure no heat-generating appliances are near your thermostat. These include lamps, TV's, stereo and computer equipment.
Keep an Air Tight House
Ensure maximum retention of heated or cooled air by adding insulation to outside walls and to the attic. Seal cracks and use storm doors and/or insulated doors to prevent air leaks. Caulk, seal and weatherstrip all seams, cracks and openings to the ouside. You can save 10% or more on your energy bill by reducing the air leaks in your home.
When you cozy up next to a crackling fire on a cold winter day, you probably don't realize that your wood-burning brick or masonry fireplace is one of the most inefficient heat sources you can possibly use. It literally sends your energy dollars right up the chimney along with volumes of warm air. A roaring fire can exhaust as much as 24,000 cubic feet of air per hour to the outside, which must be replaced by cold air coming into the house from the outside. Your heating system must warm up this air, which is then exhausted through your chimney. If you use your conventional fireplace while your central heating system is on, these tips can help reduce energy losses.
