How To Know If Your Furnace May Need A Repair

Strange Noises

If you’re hearing strange noises like banging, whistling, grinding, or rattling this could be a sign that your furnace needs immediate attention. Each of these sounds indicate a different issue, so listen carefully because ignoring these sounds and hoping they go away can result in serious damage to your furnace.

Banging or popping sounds could mean a small explosion has occurred in your furnace due to a dirty burner, whistling or grinding could indicate a blower motor malfunction, and rattling usually means something has come loose within the confines of the outer walls of the furnace.

If you’re experiencing one or more of these noises, give the experienced team at Action Furnace a call right away so we can quickly identify and fix the problem.

Little to No Heat

Insufficient heating is one of the most common furnace issues, and in these harsh negative temperatures uneven heating throughout your home can cause property damage and even pose a health risk to you and your family due to decreased air quality.

Little to no heat throughout your home could point to a number of issues, from a major clog in your duct work, to a problem with your thermostat, or an issue with your furnace’s pilot light, so make sure to call the experts at Action Furnace right away at the first sign of a chilly room or when your vents start blowing cold air.

Frequent Cycling

Another common furnace issue is the frequent cycling of the unit on and off. Thankfully this can be an easy fix, but if ignored can cause serious harm to your furnace, and with this weather, you want the most reliable heating you can get!

Furnace cycling is typically caused by a clogged furnace filter. When dirt, dust, pet hair and other contaminants start to accumulate in the filter, air can no longer flow freely, causing the blower to work harder than it needs to. When the blower overheats, the furnace turns off.

Frequent cycling can also be caused by a malfunctioning thermostat that is unable to properly read the heat, or lack thereof, in the house.

If your furnace is cycling on and off more than 5-8 times per hour, give Action Furnace a call right away. We’ll quickly clean out the blower fan, replace your furnace filter and check your thermostat, getting you back up and running, fast.

Strange Odours

Strange odours being emitted from your furnace are another issue that shouldn’t be ignored in the winter, or at all. As with strange sounds, persistent odours are caused by issues that can result in serious damage to your furnace, or can even indicate something more dangerous…a gas leak.

If you’re smelling strong sulfur or rotten eggs, this may mean you have a natural gas leak. The best thing to do is to open all doors and windows, and get out of your house immediately. After calling your utility company, the experienced technicians at Action Furnace will come out and quickly identify the cause of the leak and conduct an immediate repair.

Burning odours coming from your furnace typically point to one or more components of your furnace overheating due to excess use. Our team is trained to quickly identify these components and get them repaired quickly so they can function at their most efficient.

Another common issue is mold or mildew growth which can smell musty and damp. Mold growth occurs when there are high condensation levels in your home, or if your ducts haven’t been cleaned in awhile. The appearance of mold can greatly affect your health, causing asthma and other lung issues. Luckily, our technicians can handle both issues relatively quickly to mitigate any potential health risks. 

Be Proactive!

Don’t let emergency furnace issues leave you in the cold. Preventative, annual maintenance is the best way to ensure a well-running furnace this winter.
