What Are the Most Common Furnace Repairs?
If you’re regularly maintaining your furnace, it will be easier to spot these common furnace repairs before they become bigger issues. If you notice any of the following with your furnace, it might be time to schedule furnace repairs with one of our experienced furnace technicians.
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.
How Long Do Furnaces Last?

If you’ve recently moved into an older house, or if you’ve been in yours for many years, your furnace may have seen better days. Determining whether to repair or replace your furnace can be tricky, especially since you already have plenty of expenses and costs as a homeowner already.
If you’ve been conducting annual furnace maintenance, you should expect your furnace to last 15 to 20 years. The best thing a homeowner can do is to keep an eye on any problems and get ahead of them before they become worse—furnace repairs are likely far less expensive than buying an entirely new unit.
If your furnace is exhibiting some of the above problems, treat them as a warning sign. Schedule furnace repair as soon as you can, and keep your furnace lasting for many more years to come.
Dangers of DIY Furnace Repair
There’s plenty of good reasons to become a DIY homeowner, at least when it comes to some things. Saving money, learning a new skill, or just the achievement of doing it yourself are all great reasons to tackle a household project.
1. Mistakes Can Expose You To Danger
Repairing furnaces and air conditioners means working with complex, potentially hazardous components and processes. Natural gas (the most popular power source for furnaces in the GTA), ozone-depleting refrigerant (which, according to Ontario law, can only be handled by certified technicians), electrical wiring, ventilation, the risk of explosion or carbon monoxide leakage … oh my!
If you don’t know exactly what you’re doing, it’s easy to make a mistake. Yet the consequences could be dangerous, even deadly.
2. You Risk Voiding Your Warranty
Take a look at your appliance warranties. Most likely, they will remain valid only with proof that all furnace or air conditioning repair and maintenance work is done by a qualified HVAC professional. Is saving a few bucks with DIY really worth voiding your warranty?
3. Repair Could Take Too Long
Let’s face it; Vaughan’s climate can be harsh, summer or winter. No matter the season, you and your family don’t want to be without heating or cooling (as the case may be) for over a few hours at most. The problem is, as an amateur … er, that is … do-it-yourselfer, it’s likely to take you a lot more time to figure things out than a professional technician. And that’s even truer when HVAC replacement, rather than repair, is required.
4. You Might Not Restore The HVAC To 100% Efficiency
Okay, so maybe you will actually be able to complete the DIY fix and get your HVAC system running again. However, it might not work at 100 percent efficiency like it used to. As a result, it will end up costing you more cash for your monthly utility bills. “Cheap is expensive,” Grandma always said.
Things to Check on Your Furnace Before You Call Us
Please don’t open your furnace to examine it yourself – you need to have training and licensing in order to do this safely. That being said, there are a couple of “gotchas” that homeowners can quickly check:
- Your thermostat is set to “heat”. This can be an issue in the fall for new homeowners.
- The power switch on your furnace is set to “on”. Your furnace needs a bit of electrical power in order to run, and this switch turns off the power in an emergency or if a technician is going to work on it. This switch can get turned off by accident. Check on the side of the furnace, or near the furnace on the wall.
- The circuit for your furnace is on in your electrical panel. If electrical issues have developed, this may have been tripped. If it trips again, there may be an issue with the furnace or with the electrical wiring.
There are other issues, like blocked furnace vents or dirty filters that can cause temporary problems, but it’s better to call us for both safety and repair reasons.
