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 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 too frequently, 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 requires attention.
• Dirty Air Filter: A dirty 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. A cracked heat exchanger needs to be repaired or replaced immediately.

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 operate at only one output level – full capacity. 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 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 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. . 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 will constantly run and struggle to heat your home effectively, especially in cold weather.. An oversized 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 lead to increased energy consumption.
• Inconsistent Temperatures: Noticeable temperature differences 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 areas with inconsistent temperatures, the unit may be the wrong size.
• Excessive Noise: Oversized furnaces can make loud or unusual sounds

A qualified technician will be able to assess your home's heating needs. A Manual J load calculation can accurately determine the appropriate furnace size.. Installing the correct size unit will maximize efficiency and minimize energy bills.
