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 too frequently, 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: If the blower motor isn't functioning, your furnace may not distribute heat properly. A faulty blower motor requires attention.
• 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 dangerous gasses entering your home. 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 operate at only one output level – full capacity. This can lead to temperature fluctuations and higher energy bills because the temperature fluctuates more than with two-stage furnaces.
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. 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 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.. 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 efficient and comfortable heating. An too-small furnace won't adequately heat the space. An oversized 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 oversized furnace can cause 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 hot and cold spots, 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. A Manual J load calculation can accurately determine the appropriate furnace size.. A proper sizing calculation is a worthwhile investment for optimal comfort and energy efficiency.
