Heating Systems

Heating system typesThere are many types of heating systems: forced air, piped hot water or steam, wood burning stove, electric baseboard or gravity. All heating systems have the common purpose of establishing and maintaining a comfortable temperature and humidity level. Each system has unique characteristics which should be maintained by a professional at least once a year. However, there is simple maintenance that you can do, as described below, to improve the efficiency of your heating system.

Checklist for Heating Systems:

FORCED AIR SYSTEMS. In forced air systems, the furnace heats air which is blown through air ducts and delivered to rooms through registers.

WOOD BURNING STOVE. Wood burning stoves are made out of either cast iron or steel. Wood is burned inside the stove, radiating heat into the room and house. Wood burning stoves can be a significant fire hazard unless properly installed and maintained.

ELECTRIC BASEBOARD. For general maintenance information about electric systems, refer to the section on electricity in this section.

WALL SYSTEMS. Recessed into the wall and equipped with a blower. Vacuum to remove dust or dirt.

GRAVITY SYSTEMS. Old octopus style furnaces are characteristic of gravity systems. Due to the age of this type of system, it should be inspected annually by a qualified professional. Because it is inefficient, you may want to consider replacing it.

GAS “SPACE” HEATER. Vacuum to remove dust or dirt, take care not to extinguish pilot light.

NOTE: If your furnace or hot water heater vent into a brick chimney, make sure that the chimney has a proper liner or the chimney may fail.

Cooling Systems

Cooling system diagramThe cooling unit of your air conditioner both absorbs heat and reduces humidity. Whether you have a window unit or central air, you should try to locate the condensing unit on the shady side of your house.

Keep your unit well maintained so that it operates efficiently. An efficient system will keep the air in your home fresh and clean and will help keep electric bills to a minimum. As needed, refer to the owner’s manual for your unit.

Checklist for Cooling Systems:

CONDENSING UNIT CLEARANCE. The condensing unit of an air conditioner, which is located outside the house, is where the job of making cool air takes place. Air must flow freely for the condensing unit to function properly. Don’t allow branches or other objects to come within three feet of the unit. Turn off the power to the unit, and then vacuum or hose out any leaves or other debris that may accumulate. During winter months, it is important to cover the condensing unit with a canvas or plastic tarp to protect it from the weather.


CONDENSATION DRAIN. The condensation drain carries excess moisture away from the unit. Make sure that it’s not plugged and that it is directed towards the floor drain.


FURNACE FILTER. Your central air system uses the same blower as your furnace. Therefore, it is just as important to clean and replace the filter during the summer as it is during the winter.
