During the winter months, the last thing you want to wake up to is a furnace problem. Our heating systems are essential for keeping us warm and comfortable, so ensuring they’re working properly is a must. If you’re keeping on top of regular maintenance—such as changing the furnace’s air filter—but you’re facing one or more of the following problems—it might be time to call a furnace repair professional.

Here are some common furnace problems in cold weather for you to look out for:

1. Furnace Blowing Cold Air Instead Of Heat

Don’t panic if your furnace isn’t generating enough heat when you first turn it on for the winter season! When your furnace is blowing cold air instead of hot air, a few common furnace problems could be at play, such as a broken thermostat, the furnace’s pilot light, the furnace filter, gas supply, and leaking air ducts, among others. We’ve covered each possible cause and how to fix your cold furnace issues here.

2. Furnace Heating Is Uneven

Are you having trouble with your indoor temperatures? Uneven heating is an annoying and often costly problem. If the cold weather weren’t bad enough, when it’s freezing cold in the kitchen while the office is like a sauna—and you’ve checked everything from blocked vents to insulation—it’s infuriating! It seems like no matter what you do, you can’t get even heating. We go into each possible cause and how to handle it in this handy article about fixing your uneven heating problems.

3. Furnace Is Too Loud

Furnaces today are made to operate as quietly as possible. If you’re hearing loud noises coming from your heating system, such as screeching, whirring, banging, or the sound of metal on metal—there might be something wrong.

There may be a mechanical problem with the airflow, or you may have a clogged burner. Some issues have simpler fixes than others, but either way, you should call a professional furnace technician to take care of the issue. While you wait, you can read up on why your furnace is being so loud!

4. Furnace Smells Bad

Furnaces work hard—but that doesn’t mean they get B.O! If a strange smell is wafting from your furnace, you need to pay attention. This isn’t a cause for panic, but it could be an indicator of a serious problem. It could be as simple as that “new furnace smell,” or it could be dusty after being off all summer- but a sewage smell, smokiness, or the smell of hot rubber or plastic could be an indicator of a serious problem that needs immediate attention. Read up on the reasons you might be smelling something to make sure no one gets seriously injured.

5. Furnace Is Leaking Water

If you have a puddle next to your furnace, that is a sure sign of trouble. DIY furnace fixes are not recommended as they can be incredibly dangerous—we suggest you immediately turn off your furnace and call a professional to help with the furnace repair. The cause depends on the type of furnace you have, and even then, there can be several reasons why your furnace is leaking. One of which could be a cracked heat exchanger.

We’ve outlined what steps to take immediately and what the problem could be with your leaking furnace in this article. Don’t put this off- Call a technician now.

6. Furnace Keeps Shutting Off

Typically, a gas furnace cycles on and off 3-8 times per hour in order to maintain the temperature you’ve set with your thermostat. If it’s switching on and off every couple of minutes, there could be a problem. First, check your circuit breaker. If that doesn’t work, there are some steps you can take to troubleshoot the issue. The problem could be as simple as the thermostat setting, a blocked filter, or the size of your furnace.

It could also be something as serious as frozen pipes. Follow the steps we’ve outlined to see why your furnace is shutting off and to see if you need a professional to help fix it.

7. Dirty Furnace Filter

One of the most common furnace problems in cold weather is caused by a dirty furnace filter. Air quality is important in your home, especially if you have pets or family members with allergies or asthma. Your furnace filter does the heavy lifting in this department and should be changed out typically every 90 days, but this may vary depending on your home.

Changing your filter is an easy job and will make a big difference in your furnace health and energy efficiency—we’ve outlined how to change your filter to get you going!

8. Carbon Monoxide Leak

Carbon monoxide (CO) is an entirely odourless, colourless and tasteless gas. CO can be harmful to your health; in larger amounts, it can be lethal. We hope that you have a carbon monoxide detector in your home, as all Ontario residents should.

Furnaces are one of the major culprits for Carbon monoxide leaks and are one reason you should be getting regular maintenance. Make sure you know the signs and symptoms of carbon monoxide leaks.
