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 rapidly, 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: If the blower motor isn't functioning, your furnace may not distribute heat properly. A malfunctioning blower motor can cause reduced airflow, uneven temperatures, and loud noises. should be addressed by a technician.
• Dirty Air Filter: A clogged air filter restricts air circulation. 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 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.Two-stage furnaces provide enhanced home comfort and energy savings compared to single-stage models.

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 correctly sized furnace is crucial 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 lead to increased energy consumption.
• Inconsistent Temperatures: Noticeable temperature differences throughout your home.
• Short Cycling: If your furnace cycles 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: A furnace that's too large may produce more noise than normal.

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.
