Furnace Repair Spokane

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, reducing efficiency and potentially causing damage.
• 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 should be addressed by a technician.
• Dirty Air Filter: A dirty 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 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 may cause 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. This allows the furnace to modulate its output based on the actual heating demand, resulting in more consistent temperatures, quieter operation, and improved energy efficiency. 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.. 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 essential for efficient and comfortable heating. An too-small furnace won't adequately heat the space. An too-large furnace will short cycle, causing wear and tear, inconsistent heating, and inflated utility bills. 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 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 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.
