Your furnace is undoubtedly essential to you as a Canadian. It’s even more important if you live in Calgary and face the blistering and never-ending winter months. In the event you think your furnace has stopped working, there’s no need to panic and start a fire for warmth, we’re here to help you identify how severe your issues are. If it has stopped working, don’t grab the kindling yet, because, at Western Sky Mechanical, we provide emergency furnace repair services and can assist you in all your needs. 


There can be a couple of reasons that your furnace is acting up, and understanding the signs of a non-functional HVAC system will help you determine what to do next. An electrical issue can affect the performance of your furnace as it plays a crucial role in its operational abilities. To power your system, you rely on your home’s electrical systems. If, when you turn your furnace on, you notice your lights flickering, this is a telltale sign that something is up. As trying to deal with electrical issues yourself is highly dangerous, it’s best to leave this one to the professionals. Taking a DIY approach without proper training can lead to electrical malfunctions, which can then lead to electrical fires. Saving a couple of bucks on repairs isn’t worth burning your house to the ground over. 


Whereas you can rely on your sight to spot electrical issues (flickering lights), the next approach requires you to rely on your hearing. So listen up! If you hear rattling noises, it may mean loose panels need tightening. Loud and unusual noises can signal problems with the ductwork, the belt or even your furnace’s burner. A pinging or popping sound could be a sign of thermal expansion, which means your ductwork is getting bigger or smaller as it heats and cools. A squealing noise could indicate a belt that needs replacing or a belt connecting to the motor having slipped. Most importantly, if you hear grinding sounds, you should contact a technician because this could mean the motor bearings need work. Overall, in listening to your furnace, you can find signals that something is up. 


This next step involves you using another sense, that of smell! If you detect a scent of rotten eggs or sulfur, it can signal a gas leak. If this is the case, you want to make sure you remove yourself and your family immediately. If you’re able to safely open windows on your way out, do so. Don’t use your cell phone in the house to make a call, don’t turn on the stove, don’t open your garage door and don’t start your car if it’s close to your home. These can all lead to a gas explosion. This is the most serious of issues discussed so you must contact a trained professional for this. 

Lastly, if your furnace happens to be blowing out cold air, that’s another signal something is wrong. It’s not an air conditioning unit – it’s supposed to keep you warm, not cold! Another useful tip is to utilize local furnace cleaning services to make sure your furnace is in tip-top condition.
