There are several reasons for the lack of heat, even if the thermostat is on. One typical culprit is a dirty filter.
A blocked or clogged filter will slow down the efficiency of your heating system. If the air filter is dirty, make sure to replace it. In general, you should replace a filter every two months.
More reasons for no heat include:
- Dirty ignitor pilot
- The thermostat is on the wrong setting
- Battery issues
- Your gas furnace’s gas valve isn’t open
- The heater is cut off from the power switch
