A dirty filter causes these problems:
- Reduces volume of hot air blown out– less blow out your vents, discomfort you and your family.
- Furnace shuts down–overheats heat exchange then automatically shuts down.
Dirty air filters causes soot to build up in the heat exchanger, furnace run inefficiently and reduce it’s life span. Check the air filter every one to three months and change it if it’s dirty.
Caution: Make sure that your furnace is off (found on the furnace) and before changing the air filter shut down the thermostat.
Step #2: Check your thermostat
Your furnace maybe in good condition. Your thermostat, the control centre of your heating system, may be the perpetrator,
Do these simple steps to check the cause of the problem:
- Change your thermostat to “heat” instead of “cool.” (You never know who have been playing around with it and set it to cool.)
- Set your thermostat to 5 degrees above room temperature to see if your furnace comes on.
- Change batteries.
- Open the panel then gently blow out any dust or debris.
Step # 3: Be certain that the blower motor panel is shut
Sometimes the blower’s panel remained open, they may not have shut the panel properly If it’s not pressed in all the way, use a safety device to prevent the furnace from running. Be certain that you securely shut furnace blower panel.
Step # 4: Air duct inspection
Your furnace is working. Blower is running, hot air is coming out…in most rooms. But why are some areas in your home chilly? Your air ducts.
Inspect the handles protruding from the ducts. Dampers control the airflow. Check if they’re fully open (i.e., the handle is parallel with the ductwork).
If some of your rooms are still cold, your ducts can have gaps, cracks or holes in them allowing the hot air to escape. This is what we call leaking ducts. These leaks not only make the room cold, but it
- High energy bills
- Sucks up dust into your ducts, poor air quality contribution in your home
Check where the leaks are in the ducts and seal them with a mastic sealant.
Step # 5: Be certain that the gas valve is open
Just like the blower panel, someone may have turn off the gas valve to do a maintenance and did not turn it back on on. When off, no gas will enter the furnace, so nothing will burn. Simply turn it back on (the handle should be parallel with the gas pipe) ,and you’re good to go.
