Is Furnace Maintenance Important? 

It is the middle of the night and you have been awoken because the house is freezing. The furnace system has broken down. You depend on your home’s heating equipment to keep your family warm and comfortable during the frigid months of winter. Whether your furnace is brand new or several decades old, industry professionals all agree that participating in an annual maintenance program is a great way to make sure that you enjoy many years of reliable service from your heating system. 

Furnace Maintenance Check List 

There are a number of preventive maintenance plans in the marketplace today that can be purchased by homeowners. Whichever one you decide to buy, be sure that it includes these essential services. 

Heat Exchanger/Furnace Burner Inspection

The heat exchanger and furnace burners are extremely important components of a home’s furnace system. The heat exchanger produces the warm air that is circulated around the home via the fan system. If this essential part is damaged, it can pose a considerable risk to all living beings residing in the house. Should the furnace burners or heat exchanger become defective, either could release carbon monoxide into the living spaces of the home. Your maintenance technician will inspect these components to ensure that they are working properly. 

Furnace Fan Limit Switch & Furnace Thermostat

The fan or blower system is responsible for sending the warm air produced by the furnace to each room of the house. The furnace fan limit switch works in conjunction with the thermostat and will power up and down according to the temperature set by the homeowner. If this important part malfunctions, the fan either will stay on continuously or won’t work at all. Your maintenance technician will confirm whether the furnace fan limit switch is operating as it should. 

Furnace Gas Line

Your home’s gas line supplies the fuel needed for the furnace to heat the house. Should the gas line not be working properly, it can pose a great danger to people, pets and property. Furnace maintenance technicians are specially trained to look for leaks or other issues with your home’s gas line. If a problem is detected, it can be repaired right away.  

Furnace Flue Pipe Inspection 

The flue pipe in your furnace has a very important job, as it is responsible for removing all toxic gases from the heating system and expelling them into the outside atmosphere. During the routine maintenance check, your technician will make sure that the flue pipe is clean and free of blockages.  

Clean/Replace Filters  

All furnaces need proper airflow in order to work at maximum efficiency. A clogged filter can not only block circulation, but it can also cause the furnace to work harder, which will lead to premature wear. During the maintenance inspection, all filters will be replaced as needed.
