Make sure it's working before you need it!
The fall heating season will be here before we know it so it's a good idea to check your heating system to make sure it works properly.
If you have a forced hot air or hot water baseboard system, replace the filters and make sure the blower is working. If yours is a steam system, look at the water level in the sight glass. If it's not at the half way mark, turn on the water supply valve.
Check to ensure the pilot light is on. If not, follow the unit's instructions to light it and let it burn for a few minutes before you start up the system. Turn the thermostat setting to the heat setting, and raise the temperature several degrees to turn the heater on.
