Frequently Asked Questions about Furnace Repair

What are the most common furnace problems?

Common furnace problems can include::

• No Heat or Reduced Heat Output: This can be caused by a faulty thermostat, a clogged air filter, or a malfunctioning igniter.
• Strange Noises: Listen for any sounds out of the ordinary.
• Short Cycling: This is when the furnace turns on and off rapidly, which can be caused by a faulty thermostat, an overheating furnace, or a clogged air filter.
• Pilot Light/Ignition Problems: Make sure your pilot light is on, or your ignition system is functioning correctly.
• Blower Motor Issues: The blower motor circulates air through the furnace and ductwork. A faulty blower motor requires attention.
• Dirty Air Filter: A clogged air filter reduces airflow and decreases furnace efficiency. . It can also cause overheating and damage..
• Cracked Heat Exchanger: This is a serious safety hazard, as it can lead to carbon monoxide leaks. This is considered an emergency.

Don't attempt DIY repairs if you're not qualified.

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

Single-stage and two-stage furnaces differ in their heating output capabilities:
Single-stage furnaces have only one setting, they either operate at 100% or are off. This can lead to uneven heating and fluctuating bills because the furnace is either running at its maximum setting or completely off..
Two-stage furnaces can run at both low and high speed. They work by running at a lower speed most of the time and switching to high speed when necessary.Two-stage furnaces provide enhanced home comfort and energy savings compared to single-stage models.

What is a heat exchanger in a furnace?

The heat exchanger is a vital component 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.

How can I tell if my furnace is the correct size for my home?

A properly sized furnace is crucial for optimal home comfort. An too-small furnace will constantly run and struggle to heat your home effectively, especially in cold weather.. An too-large furnace will cycle on and off too frequently, wasting energy and shortening the system's lifespan.. Signs that your furnace may not be correctly sized include::

• High Energy Bills: An incorrectly sized furnace can lead to increased energy consumption.
• Inconsistent Temperatures: Noticeable temperature differences throughout your home.
• Short Cycling: If your furnace turns on and off frequently, it may not be heating your space efficiently and wasting energy.
• Poor Air Quality: If the airflow from the vents seems weak or there are areas with inconsistent temperatures, the unit may be the wrong size.
• Excessive Noise: Oversized furnaces can make loud or unusual sounds

If you suspect your furnace is improperly sized, it's essential to consult with an HVAC professional. Ask a professional for a load calculation to confirm appropriate sizing. A proper sizing calculation is a worthwhile investment for optimal comfort and energy efficiency.
