Furnace issues can happen out of the blue. It is important to remember to contact us any time the furnace has an issue. By having it inspected regularly, you can help prevent further damage to the parts of it. If there is an issue with the furnace, we can inspect and repair it as soon as possible for you. This will help you to have an efficient furnace as well.
Furnace issues with the filter
One of the furnace issues you might notice deals with the filter. A clogged air filter is one of the biggest causes of furnace problems. If your furnace turns on but does not blow hot air very long, there is a good chance that your filter is too clogged. When dust builds up on the filter it reduces airflow through the system and this can cause your furnace to shut off. So check for dirty air filters. If this is the issue, it could have caused soot to collect in your heat exchanger. So make sure you schedule a non-emergency furnace cleaning and safety check.
Sometimes the furnace issues occur because of components. If the furnace does not work, it may be from the thermostat. Make sure the thermostat is set correctly. This is more common with programmable thermostats because you might have set a program last season, but forgot to adjust it as the temperatures have changed.
Check the circuit
Occasionally, something has caused the circuit breaker to the furnace to trip, turning it off. Also, there is usually a switch (looks just like a light switch) near the furnace that turns it on and off. Verify that nobody turned this off by mistake, while trying to turn off another light
Modern gas furnaces no longer use standing pilot lights. Instead they use either intermittent pilot or hot surface ignition to start the furnace. These are more efficient than a standing pilot light because they are not constantly burning a small amount of gas just to keep the furnace ready to start. When the thermostat signals the furnace to switch on, electricity runs through the igniter and heats it up. If you notice an issue with the furnace, make sure to contact us so we can inspect it for you.
