Just like any mechanical system, furnaces need regular maintenance to run correctly and efficiently. A furnace tune-up entails thoroughly inspecting and cleaning your furnace and its parts. Doing this at least once a year, preferably in the fall, is essential before using the unit regularly.

The exercise restores optimal performance and extends the lifespan. Furnace repair service Toronto provides expert solutions to fix any issues with your heating system, ensuring it runs smoothly and efficiently during the cold weather. The good thing is that the furnace lets you know when it’s time to schedule the tune-up. The signs are:

Decreased Efficiency


If it’s taking longer to heat the house, there’s a drop in furnace efficiency. The problem is most likely with the burners and should be addressed immediately. Other causes are dirt accumulation on the parts, which a professional will take care of during the furnace tune-up.

When inspecting the unit, experts determine whether upgrades are necessary, such as a new furnace filter or humidifier. When the furnace is too old, they will suggest a replacement to improve efficiency and prevent breakdowns.

Weird Noises

Loud banging or squealing noises coming from the furnace signify a problem. Switching off the unit and calling in a technician for repairs before turning it on again is advisable. Possible issues are a loose blower wheel or failing motor bearings.

Wear and tear is also a factor, especially in older furnaces. After an inspection, the professional will suggest replacing the worn-out parts, oiling the motor, or tightening the blower wheel to stop the noise. However, it’s time to install a new furnace when this doesn’t resolve the issue.

Yellow Pilot Light

When the pilot light is yellow, the furnace is dirty and needs cleaning. A furnace tune-up will take care of this and ensure all the other parts are in good working order. Yellow light results from poor combustion, causing increased carbon monoxide production. This gas is odorless and colorless but fatal when inhaled in large quantities.

Thermostat Issues

If the furnace turns on and off frequently or doesn’t work, there’s likely a problem with the thermostat. It could be as simple as a loose wire that needs tightening or replacement. However, it’s best to leave this to a professional, as messing with the wires could cause more damage.

Excess Dust And Debris Around The Furnace


A telltale sign that your furnace needs a tune-up is if you start to see excess dust and debris around the unit. It means that the filters are dirty and need replacing. If you don’t do this, the furnace works harder and less efficiently. As a result, your energy bills will increase. Not to mention, the dirt and debris cause the furnace to overheat and break down.

Call a professional for a tune-up if you start seeing dust and debris around your furnace. They will replace the dirty filters and inspect the rest of the unit to ensure it is clean and working correctly. The effort will also improve indoor air quality.

High Energy Bills

If you notice a sudden spike in your energy bills, it could be a sign that your furnace is not working as efficiently as it should. Issues such as worn-out parts, a dirty filter, and clogs slow down the unit. It takes longer to heat the space, causing increased energy use. A professional will identify and fix the problem, normalizing the energy consumption.

Cold Spots In Your Home

Furnace Tune-Up

The furnace is not distributing heat evenly when experiencing cold spots. This is often due to a problem with the blower fan or ductwork. A professional can identify and fix the problem for your home to achieve even heat.

Call Professionals Right Away

If you notice any of these signs, it’s time to schedule a furnace tune-up with a professional. Doing so will save you money in the long run. Moreover, it will protect you and your family by preventing hazardous situations like carbon monoxide leaks.
