Before you call the heating repair technician, here are suggestions to keep your furnace working great this winter. Here are some furnace tips to understand and maintain your heater. Here you will learn how test your furnace, how to turn it on and what to do if it won’t light.
Here’s how to turn on your heater:
Check the breaker that controls your heater. Turn it on.
Look for the furnace switch. Usually it’s near the heater. Turn it on.
Set your thermostat, switch the heater to heat, turn up the temperature and the heater ought to be going!
How to change your furnace filter
The furnace filter takes the dust out of the air that your heater is moving. After a while, it’s collected as much dust as it can without slowing up the airflow in your air system. That’s the time to change the filter. Change it every year, in the fall, or more often, as needed. Filters are cheap and only take a few minutes to swap out.
Open the furnace or filter door, Sometimes you have to look around a little to find it. It will be in the ductwork that returns air to your furnace.
Slide the old filter out. You can tell if it needs changing if you see it covered with dust. You ought to be able to see through the filter. If you can’t, change it. Really, filters are cheap enough, change it anyway.
Slide in the new filter. Write the date on the visible end of the filter.
Close the door.
How to test your Furnace’s airflow.
Do you have a cold room in your house? Maybe you are wondering if the furnace is pumping air at all? Here’s an easy way to check.
Turn off your furnace at the thermostat. Take a standard sized plastic garbage bag and tape it around a heat register. Turn on the furnace. Time how many seconds it takes to fill up the bag.
Seconds: 2 = 75 CFM (cubic feet/minute)
Seconds: 4 = 40 CFM
Seconds: 10 = 20 CFM
If your system is pumping less than 10 CFM, then you need to get the system checked out. (See below)
What to do if your furnace won’t ignite
OK, the house is cold, no air is being pumped. The furnace is quiet. You hate to call the service guy and have it be something you could have fixed yourself. What to do?
Check the furnace switch, Is it on?
Is the thermostat set correctly? Is it switched to heat? Is the temperature set high enough?
If the thermostat has batteries, are they fresh?
Is the venting for the furnace blocked by snow or ice? (See below)
Is the circuit breaker in the breaker box switched on?
Is the furnace door properly closed?

If your heater isn’t moving air and you’ve checked all of the above, you might have a burnt out fan motor. Call the service technician and get them to check it out.
Do you smell gas?
