Look for the furnace switch. Generally it’s near the heater. Turn it on.
Set your thermostat, switch the furnace 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 furnace 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 see if it needs exchanging if you see it covered with dust. You ought to be able to see through the filter. If you can’t, change it. Actually, filters are cheap enough, replace it anyway.
Slide in the new filter. Write the date on the visible edge of the filter.
Close the door.
How to test your Heater’s airflow.
Do you have a cold room in your house? Maybe you are wondering if the heater is pumping air at all? Here’s an easy way to check.
Shut down 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 sack.
Seconds: 2 = 75 CFM (cubic feet/minute).
Seconds: 4 = 40 CFM.
Seconds: 10 = 20 CFM.
If your system is pumping below 10 CFM, then you need to get the system checked out. (See below).
What to do if your central heater won’t start up.
OK, the house is cold, no air is being pumped. The heater is quiet. You do not like to call the service guy and have it be something you could have fixed yourself. What to do?
Check out the furnace switch, Is it on?
Is the thermostat set correctly? Is it switched to heat? Is the temperature level 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 correctly closed?
Do you have to change the furnace filter?
If none of the above are the problem, call your heater repair technician and they should be able to diagnose and fix the problem.
How to remove vent blockages.
If you think the heater vent is plugged with ice or snow, here’s what you should try.
Switch off the heating system at the heater switch or at the breaker box. Them go clear the obstruction, when done switch the heater back on.
What to do if your heater isn’t blowing air?
If your heater isn’t moving air and you’ve checked all of these, you may have a burnt out ventilator motor. Call the service technician and get them to take a look.
Do you smell gas?
Gas smells a bit like rotten eggs. It can explode or it can asphyxiate you. If you smell gas, don’t flip any switches. Open your windows and go to a neighbors to call the gas company, and/or the fire department or your furnace repair technician, right away. Don’t remain in a house that is leaking gas.
