What are the signs that my furnace needs to be replaced?

If your furnace is exhibiting any of the following signs, it may be time for a replacement:
  • Age: If your furnace is 15-20 years or older, it is likely nearing the end of its lifespan and more expensive to operate.
  • Frequent Repairs: If your furnace requires frequent and costly repairs, it may be a better financial decision to replace it than to continue fixing it.
  • Increasing Energy Bills: A significant increase in your heating bills could indicate that your furnace is losing efficiency.
  • Inconsistent Heating: Uneven temperatures throughout your house could mean your furnace is no longer distributing heat evenly.
  • Strange Noises: Listen for odd noises coming from the unit.
  • Yellow Flame: A healthy furnace flame should be blue. A yellow flame suggests a problem with the burners or venting. A yellow flame requires immediate attention.
  • Dry Air: If you notice excessive dryness, a new furnace could provide increased comfort.
It's important to address issues as soon as possible.

What causes a furnace to stop working?

There are several reasons why your furnace might stop working, ranging from simple issues to more complex problems. Here are some possible culprits:
  • Lack of power: Check the circuit breaker to ensure the furnace is receiving power. A tripped breaker is a common and easily resolved problem.
  • Thermostat problems: Check that the thermostat is set correctly to 'heat' and at a temperature higher than the current room temperature. Replace batteries if the display is blank or not working. Try resetting the thermostat or replacing the batteries. If that doesn't solve the problem, the thermostat may need to be replaced.
  • Clogged air filter: A dirty air filter can cause many problems. Try replacing the filter.
  • Ignition problems: The igniter or pilot light (in older furnaces) is responsible for lighting the burners. In newer furnaces, electronic ignition systems control this process and should be checked if there are problems.
  • Blower motor issues: The blower motor is crucial to distributing warm air throughout your home. If the blower motor is broken, the furnace may not produce enough heat.
  • Gas supply problems (for gas furnaces): Make sure the gas supply valve to the furnace is turned on.. Check that there are no gas leaks.
  • Other component failures: Other components, such as the inducer motor, capacitor, or pressure switch, might be responsible.
It is typically best to avoid trying to fix the furnace on your own unless you're a qualified HVAC professional.
