Frequently Asked Questions about Furnace Repair

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 variety of issues.
• Strange Noises: Listen for any sounds out of the ordinary.
• 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 dirty filter restricts air circulation. 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. They work by running at a lower speed most of the time and switching to high speed when necessary. 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 is a vital component in a furnace. It is responsible for transferring heat from the combustion process to the air that circulates throughout 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.. Regularly checking and cleaning your heat exchanger and scheduling professional maintenance are crucial for ensuring its proper function, preventing cracks, and maximizing its lifespan.

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 won't adequately heat the space. An too-large furnace will cycle on and off too frequently, wasting energy and shortening the system's lifespan.. Here are some signs your furnace may be improperly sized:

• High Energy Bills: An oversized furnace can cause increased energy consumption.
• Inconsistent Temperatures: Noticeable temperature fluctuations between rooms.
• Short Cycling: If your furnace turns on and off frequently, it could be an indication and wasting energy.
• Poor Air Quality: If the airflow from the vents seems weak or there are hot and cold spots, the unit may be the wrong size.
• Excessive Noise: A furnace that's too large 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.
