Troubleshooting Common Furnace Problems


Troubleshooting Common Furnace Problems

Winter is here and temperatures are dropping fast in Winnipeg. It is common for temperatures to drop below zero here. In fact, the average January temperature is -15.4 degrees Celsius.


Under these conditions, your furnace is going to be running overtime. Issues are sure to arise as the below-freezing temperatures burden your system. The last thing you want is a broken furnace during these frigid winters.


Read on to learn how to diagnose and troubleshoot common furnace issues. Explore topics such as HVAC maintenance and furnace problems that you are capable of looking into.


Clean the Ducts

One common problem that homeowners see with their furnaces is a lack of airflow. Your home does not get comfortable from a temperature perspective. It seems like your furnace cannot keep up with the thermostat setting.


This is a good time to check airflow coming from the vents. Place your hand over the vents when the furnace turns on. Check to see if there is a strong and warm airflow.


If not, your ductwork may be clogged up. It is not uncommon for ducts to get filled with dust and debris. A significant buildup of dust and debris blocks the efficient flow of hot air.


Filter Replacement

Replacing the air filters is one of the easiest things a homeowner can do for maintenance. While generally an easy task, it is critical for your furnace’s operation.


Depending on your furnace model, air filters require replacement every one to three months. This allows the filters to serve their primary purpose; to block dust, debris, pollutants, and more from entering the ductwork. Without a clean filter, your furnace becomes inefficient.


Pilot Light

Your pilot light needs to be on for the furnace to work properly. If you notice that the pilot light is off, it is time to reignite it.


Most manufacturers put ignition steps right on the unit. Usually, it is simple as turning a knob or pushing a button.


This sends gas to the valve and allows you to relight it with a match or grill lighter. Remember, your pilot light should burn blue. If it burns yellow, it indicates the presence of carbon monoxide.


More Complex Furnace Problems

Furnace maintenance is not always easy. Sometimes, it requires a professional touch. You may look inside the furnace and spot issues.


A cracked heat exchanger is a serious issue that needs immediate attention. The blower belt is another critical component. It is part of the motor and enables the blower fan to run.


It is common for it to snap or fray, which leaves the furnace incapable of blowing hot air. Ball bearings and the blower capacitor are other crucial parts. All of these issues likely need professional experience to fix.


Your Guide to Resolving Furnace Issues

Troubleshooting a furnace can be simple, but in other cases is a complex business. It is important to understand that you are dealing with natural gas or electricity. Safety is the most important factor in furnace repair.
