Frequently Asked Questions about Furnace Repair

Having problems with your heating system? Get answers to common questions about furnace repair and find trusted local technicians.

What is a heat exchanger in a furnace?

The heat exchanger plays a key role in a furnace. It warms the air blown into your home. The heat exchanger also acts as a barrier between the combustion gases and the circulating air, preventing harmful gases, such as carbon monoxide, from leaking into your living space.. Cracks in the heat exchanger can be very dangerous, causing carbon monoxide to enter your house. Annual maintenance by a professional is highly recommended.

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 less efficient and more prone to breakdowns.
  • Frequent Repairs: If your furnace requires constant attention, it may be more economical 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 home or business could mean your furnace isn't functioning as it should.
  • Strange Noises: Listen for odd noises coming from the unit.
  • Yellow Flame: A healthy furnace flame should be blue. A yellow flame suggests the presence of carbon monoxide, which is a serious safety hazard. A yellow flame requires immediate attention.
  • Dry Air: If you notice excessive dryness, a new furnace could provide increased comfort.
If you notice one or more of these warning signs, have a qualified HVAC technician inspect your furnace.

How do I maintain my furnace?

Preventative maintenance is key to keeping your furnace running efficiently and safely and avoiding breakdowns. Regular maintenance includes::
  • Change or Clean Air Filters: Change your furnace air filter at least every three months, or more often if needed. If you have pets or allergies, changing the filter every month is recommended.
  • Annual Inspection and Tune-Up: It's essential to schedule professional furnace maintenance once a year, preferably before the start of the heating season.. This will ensure all components are functioning correctly and identify any potential problems.
  • Clean the Area Around the Furnace: Keep the area around your furnace clean and free of debris. Maintain a clear space around the furnace for optimal operation.
  • Check the Thermostat: Make sure your thermostat is working correctly and set to the desired temperature.
  • Inspect Ductwork: Inspect your ductwork for any leaks or damage and have them repaired to prevent energy loss and maintain efficient airflow.
Regular maintenance is an investment that protects your system and enhances comfort.

Why is my furnace blowing cold air?

Several problems can cause your furnace to blow cold air::
  • Pilot light or ignition problems: In older furnaces, the pilot light needs to be lit for the burners to ignite. Ignition issues are a common culprit.
  • Thermostat issues: An incorrectly set or malfunctioning thermostat can prevent the furnace from turning on or make it cycle improperly. Check that your thermostat to ensure the system is set to 'heat' and the temperature setting is higher than the current room temperature.
  • Overheating: If the furnace overheats, it could activate a limit switch. This is typically caused by a restricted airflow, often due to a dirty air filter.
  • Ductwork problems: Leaks in your ductwork can allow heated air to escape into unconditioned spaces, reducing the amount of warm air that reaches your rooms.. This can also result in the furnace blowing cold air, especially if the leak is near the beginning of the ductwork run.
If you're not able to identify the cause and fix the problem yourself, contact a furnace repair professional.
