Is your furnace acting up? Get answers to common questions about furnace repair so you can make informed decisions.
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 uneven heating and fluctuating 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 pilot light?
A pilot light is a tiny flame used to ignite the main burners. When the thermostat signals for heat, the pilot light ignites the main burners, heating the air. . While pilot lights are generally reliable, they can sometimes go out or malfunction, requiring relighting or repair. They also consume a small amount of gas continuously, even when the furnace is not actively heating. .
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 is the average lifespan of a furnace?
The average lifespan of a furnace is typically 15 to 20 years. However, this can vary depending on several factors: is influenced by:
Maintenance: Preventative maintenance significantly impacts the life of your furnace. A preventative maintenance plan can make your furnace more reliable.
Usage: The more frequently you use your furnace, the shorter its lifespan will be.
Quality: Well-built models tend to last longer.
Proper Installation: Correct installation is crucial for optimal performance and longevity..
If your furnace is over 15 years old and starting to experience frequent problems, it may be time to consider replacing it.
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 may cause uneven heating and fluctuating 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 pilot light?
A pilot light is a tiny flame used to ignite the main burners. When the thermostat signals for heat, the pilot light ignites the main burners, heating the air. . While pilot lights are generally reliable, they can sometimes go out or malfunction, requiring relighting or repair. Electronic ignition systems are usually safer and more efficient.
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. . 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.
What is the average lifespan of a furnace?
The average lifespan of a furnace is around 15-20 years. How long your particular furnace will last depends on several factors, including::
Maintenance: Regular maintenance significantly impacts the lifespan of your furnace. A preventative maintenance plan can make your furnace more reliable.
Usage: The more frequently you use your furnace, the shorter its lifespan will be.
Quality: Well-built models are typically more durable.
Proper Installation: Correct installation is key to longevity.
