Is Your Furnace Ready For the Heating Season?
If your home has a gas furnace, it’s important to learn how to check your system for potential problems to prevent unexpected breakdowns or inefficient operation.
Replacing Your Furnace Filter
Paper or fiberglass furnace filters should be replaced every three months, or as recommended by the filter manufacturer. The furnace should be turned off before changing the filter. Never operate the furnace without a filter in place. Open the cover of the unit and then remove the filter. If the filter is reusable, vacuum it to clean the surface, or wash and dry it following the filter manufacturer's instructions.
Turning the Furnace On
A gas furnace is typically controlled through the same thermostat as the air conditioner. This means that when the weather turns cold, you can simply turn your thermostat to the 'warm’ or 'heat’ setting and then adjust the temperature to your liking.
Ensure There Is Airflow Throughout the Home
Ensure that all vents are open in every room and that the vents are not obstructed by rugs, drapes or furniture. If the inside of the vents appear dirty, have the ducts professionally cleaned to remove dirt and debris that can restrict airflow and cause unhealthy indoor air quality.
If Your Gas Furnace Will Not Ignite
First, check that the thermostat is turned up a few degrees above current the room temperature. It may need to be 3-4 degrees higher. If it still does not turn on, check the electrical panel.
What To Do If You Smell Gas
If you ever smell gas coming from the furnace, leave the home and call your gas company right away.
Schedule Annual Heating System Maintenance
Regular system maintenance is important for ensuring that the furnace is operating safely and reliably. During an annual heating system inspection your technician will lubricate the furnace ports and bearings, reducing the amount of energy the unit needs to operate. Your technician will also clean the burners if they appear dirty and check for carbon monoxide leaks.
