Why is My Heating System Not Working?

by Subodha Senevirathne

There are several common reasons why your heating system might not be working:

  • Thermostat Issues: The thermostat may be improperly set, or the batteries may need replacing. Ensure it’s set to the correct temperature and heating mode.
  • Power Supply Problems: Check if your heating system is receiving power. Circuit breakers may have tripped or fuses may have blown.
  • Dirty or Clogged Filters: Filters in HVAC systems can get clogged with dust, restricting airflow and causing the system to malfunction.
  • Ignition or Pilot Light Problems: For gas heating systems, the pilot light may have gone out or there could be issues with the ignition system.
  • Blower Issues: The blower motor may be faulty or malfunctioning, which can prevent warm air from circulating through your home.
  • Gas Supply Issues: If you have a gas heating system, ensure the gas supply is active and there are no blockages in the lines.

If these basic checks don't resolve the issue, it may be necessary to call a professional technician for a more thorough inspection.
