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 are the most common furnace problems?

Common furnace problems range from minor issues to major system failures, such as:
  • No Heat or Reduced Heat Output: This can be caused by a faulty thermostat, a clogged air filter, or a malfunctioning igniter.
  • Strange Noises: Unusual sounds like banging, squealing, or rumbling can indicate problems with the blower motor, igniter, or other components.
  • Short Cycling: This is when the furnace turns on and off rapidly, reducing efficiency and potentially causing damage.
  • Pilot Light/Ignition Problems: In older furnaces, a faulty pilot light can prevent the furnace from igniting. In newer furnaces, issues with the electronic ignition system can cause similar problems.
  • Blower Motor Issues: The blower motor circulates air through the furnace and ductwork. A faulty blower motor should be addressed by a technician.
  • Dirty Air Filter: A clogged air filter reduces airflow and decreases furnace efficiency. . It may lead to more serious problems.
  • Cracked Heat Exchanger: This is a serious safety hazard, as it can lead to carbon monoxide leaks. This is considered an emergency.
If you are experiencing any of these issues, it is important to contact a qualified HVAC professional for diagnosis and repair.

What is the difference between a single-stage and two-stage furnace?

Single-stage and two-stage furnaces have operational differences.
Single-stage furnaces have only one setting, they either operate at 100% or are off. This can lead to temperature fluctuations and higher energy bills because the furnace is either running at its maximum setting or completely off..
Two-stage furnaces offer two levels of heat output: a lower setting for mild weather and a higher setting for colder temperatures. This allows the furnace to modulate its output based on the actual heating demand, resulting in more consistent temperatures, quieter operation, and improved energy efficiency. A two-stage furnace may be a more expensive initial investment, but it can provide greater comfort and savings over time.

What is a heat exchanger in a furnace?

The heat exchanger plays a key role in a furnace. It is responsible for transferring heat from the combustion process to the air that circulates throughout your home. . It's a safety feature separating exhaust gases. Cracks in the heat exchanger can be very dangerous, causing carbon monoxide to enter your house. Annual maintenance by a professional is highly recommended.
