How does your furnace really work? You know that you turn the thermostat up or down and it comes on or turns off. What more do you need to know?

If you want to reduce the need for an emergency service call there are a few things you should know.

1. Your furnace while not a living creature; it needs to breathe. Basic principles of air flow, if air can’t get in, the furnace cannot blow hot air out.
Change your filters regularly and make sure there is plenty of air flow to your furnace
DO NOT block intake grilles with furniture or other items, move furniture a few inches from the wall to allow air flow
• If located in a closet, the closet should have a louvered door
Do not store items on or around the furnace

2. Most modern furnaces are very safe, however, regardless of being gas or electric they have a heating element of some variety.
DO NOT store flammable items on or near a furnace, including cardboard boxes, clothes, chemicals…
DO NOT place items on top of the furnace in the summer and forget to remove them before winter
Keep the furnace clean of dust and other contaminants that might ignite

3. Dust dirt and other contaminants can clog the pressure switch ports, flame sensor, control board, etc
• This may cause the furnace to not start
• May cause failure that requires replacement of parts
• May cause allergy attacks
• May cause the belt to slip

Why do furnaces always seem to break down after hours during unbearable cold spells?

It is no coincidence, you come home from work and kick up the thermostat, the furnace is working to warm the cold house and due to any of the above items, it has to work even harder and something has to give. That is why so many emergency repairs are done at night in bitter temperatures.

What can you do to prevent emergency calls?

When you call for a routine service the technician should clean the furnace of dust and contaminants, inspect the air flow to ensure the furnace is getting enough air, check all wiring, check the filter, and look at the belt to ensure it is properly adjusted and in good shape. This is a relatively inexpensive service call that will help ensure the continued efficiency of your furnace. In many cases the warranty on your furnace requires regular service every 6 months. There are many youtube videos showing how to clean your furnace, however, that will not typically cover your warranty requirements and there are parts they may be damaged if you are not careful.

Regular service of your furnace will not guarantee that you will never have a furnace failure, however, but it will greatly reduce the possibility of needing to call someone out at midnight in the middle of a snowstorm.
