If you follow a high-quality maintenance plan with your furnace and take care of it through the years, it should last a long time without breaking down or causing problems. However, furnaces aren’t built to last forever, so you may experience some sort of problem near the end of its lifespan. You may also experience issues if you don’t keep up with the recommended maintenance plan. No matter what, having your furnace breakdown in the middle of winter is daunting and can make your family uncomfortable.

 

If you suspect that your furnace is malfunctioning, there may be a few issues and causes that you need to look for. Some issues are easily fixable by yourself, but others do need a professional technician to properly diagnose and repair the problem. The following list will highlight some of the problems that will need to be addressed by a professional.

Anything to do with Electricity

Your furnace can’t run properly if it’s not getting power. If you notice any electrical problems when you turn on your furnace (for example, if your lights start to flicker or if the furnace doesn’t turn on right away), then you will need to call in a professional electrician. Even if you have a basic understanding of how electricity works, you should still call for help as working with electricity can be very dangerous.

The Furnace is Making Weird and Loud Noises

Keep an ear out for any odd noises coming from your furnace. You may notice that the noise is coming from your ductwork, which isn’t a cause for concern and you can just insulate the pipes to limit the sounds that you hear. However, if the sound is coming from the furnace itself, then it could be a problem with the pilot light, burner or belts. Here are a few noises that you may hear from your furnace and what it could mean:

 

  • Rattling sound: This could be as simple as a panel that is loose, which just needs to be tightened to fix the issue. If this sound persists after tightening all the panels, call your furnace maintenance team for further instructions.
  • Popping noise: This could be the result of expansion due to heating or cooling. You may notice this noise during the first week of the summer or winter while your system gets used to the new temperature.
  • Squealing sound: If you hear squealing, it is most likely due to a slipped or broken belt that connects the motor to the fan.
  • Grinding noise: This noise is the most cause for concern because the motor bearings might be compromised, and you should call your furnace maintenance team immediately.

 

No matter what kind of unusual sounds you hear from your furnace, you should call a technician to check it out. Even if the sound seems minor, it could lead to future problems that will cost a lot more to replace rather than repair.

The Furnace Turns On And Off Quickly

If you notice that your furnace is turning on and off quickly, there are a few things that may be causing this issue. The most common cause is a dirty air filter. Think back to when you last changed your air filter. If you can’t remember the last time you changed your air filter or if it has been over a year, you should think about replacing it. This is an easy fix that you can do yourself in a matter of minutes.

 

If this problem still persists after you changed the filter, then you should call your technician to do a full diagnosis. There could be an issue with the belts or blower motor.

The Furnace is Emitting a Bad Odour

This is a major issue as it could be a gas leak. If you smell gas or a rotten egg odour, you need to take action immediately. First, leave the house right away and do not touch anything electrical, including turning on or off your lights. You should also avoid using your cell phone inside of the house, wait until you are outside and far away from your home before making a call to emergency services. Another thing to keep in mind is that if your car is in the garage, do not turn on the car or even open the garage door, as it could cause an explosion.

Your Furnace is Produce Cold Air

When your furnace is blowing cold air, it can be because of a blockage in the blower. Clear the dust and debris from the blower to see if that fixes the problem. Another thing to look for is a flashing red or green light. Your furnace should be good if the light is green, but if the light is red, you need to call your maintenance team to get it checked out. If you notice that there is no light, then your blower motor, thermostat, or the furnace control board could be compromised.

Check the Pilot Light

A good indication to see if your furnace is performing optimally is by checking the pilot light. If the flame is not blue, there could be a problem with the combustion chamber, which could lead to excess carbon monoxide. Carbon monoxide is very dangerous and it is hard to detect since it doesn’t emit any odour or colour. Make sure you have a working carbon monoxide detector near the furnace and your vents. If the flame isn’t blue or looks off to you, you should call an HVAC technician to check it out.

Upgrade Your HVAC System

The best way to ensure that your furnace is running optimally is to replace your current one if it’s giving you a lot of headaches. Constantly repairing different aspects of your furnace can end up costing more than if you get a new unit. A brand new HVAC system can vary in cost, averaging anywhere from $3k-$12k in price. For most people, that is quite a bit of money to conjure up at one time. In situations like that, many people will take out a personal loan or use a credit card. A great way to cut down on costs for your HVAC system is to rent both your furnace and air conditioning unit. There are many high-quality and reputable companies that offer energy-efficient bundles that allow you to save money on your energy bills and your monthly rental payments.
