Winters in Venetia, PA can be brutal, and a furnace’s service comes in handy during this time. Unfortunately, your furnace may develop problems and refuse to turn on when you need it the most. Here are some reasons why your furnace won’t come on.

Poor Airflow

Furnace filters trap debris, dust and other contaminants. Over time, these pollutants accumulate on your filter and restrict smooth airflow. Proper airflow is necessary for heating system’s burners to ignite.

Therefore, when a clogged filter blocks adequate airflow, your furnace will not start. Consider inspecting your air filter and changing it if it is blocked.

Gas Supply Issues

There is no need to panic if your furnace does not turn on because the issue may be as simple as forgetting to turn on your gas supply. You can check your shut-off valve to confirm whether it is getting gas supply.

You can also try checking whether other appliances that use gas in your house are working. If they are working, there might be a problem interrupting the gas supply to your furnace.

Be aware of a rotten egg smell from your gas heating system to know whether you have a leak. Gas leaks are dangerous and may result in an explosion. If you notice this smell, evacuate everyone in your home, and reach out to your technician for assistance.

Thermostat Issues

Your furnace might not heat your home if you forgot to set your thermostat to “Heat.” You can also look out for an error message in modern thermostats. The message usually appears when there is a communication problem between your thermostat and the furnace.
