Knowing the signs that your furnace needs repair can help you avoid more significant issues and ensure your heating system runs efficiently. In this furnace repair guide, we’ll cover the common furnace issues signs and when it’s time to call a professional.
10 Common Furnace Problems and Solutions
Here are some common furnace problems you might encounter, along with their solutions:
1. Furnace Not Working
When your furnace isn’t working at all, it can be alarming, especially during a cold spell. If your furnace still doesn’t respond, the issue could be related to a malfunctioning thermostat, a blown fuse, or a more serious problem like a broken fan motor or a damaged control board.
2. Uneven Heating
Uneven heating and furnace troubleshooting in your home can be frustrating, leaving some rooms uncomfortably cold while others may be too warm. Additionally, leaky or poorly insulated ducts can result in heat loss before the air reaches certain rooms. Another possibility is that your furnace is not the right size for your home, leading to inadequate heating in larger spaces.
3. Furnace Age
If your furnace is ageing, you may notice it requires more frequent repairs. Also, your energy bills are steadily increasing. While regular heating maintenance can extend the life of your furnace. There comes a point when it’s more cost-effective to replace it with a newer model. A professional HVAC technician can clean or replace air filters.
4. Frequent Cycling
Frequent cycling, or short cycling, occurs when your furnace repeatedly turns on and off within short periods. This can be caused by several issues, such as a dirty air filter, which restricts airflow and causes the furnace to overheat and shut down prematurely. A professional HVAC technician can make the necessary adjustments to restore proper function.
5. Strange Noises
Banging, clanging, or rattling noises often indicate loose or broken components. Furnace malfunction such as a loose belt, a broken blower wheel, or a dislodged panel is a furnace repair warning sign. If you hear a grinding noise, it could be a sign that the motor bearings are worn out, which could lead to motor failure if not addressed.
6. Unusual Odors
A burning smell from your furnace could indicate that dust and debris are burning off after the furnace has been inactive for a while. This is usually harmless if the smell dissipates quickly. However, if the smell persists, it could indicate an electrical issue or overheating components, which could pose a fire risk.
7. Yellow Pilot Light
The colour of your furnace’s pilot light can reveal important information about the health of your system. However, if the pilot light turns yellow, it could be a sign of incomplete combustion, which may result in the production of carbon monoxide a colourless, odorless gas that can be deadly in high concentrations.
8. Furnace Running Continuously
If your furnace seems to run non-stop, it’s not only an indication that something is wrong but also a sign that your energy bills might be higher than usual. In some cases, your furnace might be too small for your home, meaning it’s unable to heat the space adequately and runs constantly to try and keep up.
9. Poor Air Quality
Additionally, issues like leaky ducts or a malfunctioning furnace can circulate contaminants throughout your home, aggravating allergies or respiratory conditions. If you suspect your furnace is contributing to poor air quality, it’s important to have a professional inspect the system. Then they replace filters and clean the ducts to ensure that the air in your home remains clean.
10. High Energy Bills
Leaky ducts can also cause warm air to escape, leading to more energy being used to maintain the desired temperature. A professional inspection can help identify inefficiencies in your system, recommend repairs or diagnose heating system issues, and improve your furnace’s performance, ultimately saving you money on energy costs.
