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: Unusual sounds like banging, squealing, or rumbling can indicate problems with the blower motor, igniter, or other components.
• 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: 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 clogged air 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 dangerous gasses entering your home. A cracked heat exchanger needs to be repaired or replaced immediately.

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 differ in their heating output capabilities:
Single-stage furnaces have only one setting, they either operate at 100% or are off. 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. 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 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.

How can I tell if my furnace is the correct size for my home?

A properly sized furnace is essential for optimal home comfort. 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.. Here are some signs your furnace may be improperly sized:

• High Energy Bills: An incorrectly sized furnace can lead to increased energy consumption.
• Inconsistent Temperatures: Noticeable temperature fluctuations between rooms.
• Short Cycling: If your furnace cycles 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

A qualified technician will be able to assess your home's heating needs. Ask a professional for a load calculation to confirm appropriate sizing. Installing the correct size unit will maximize efficiency and minimize energy bills.
