Bring on the Bbrrr! 9 Signs You Need Furnace Repair

Heating Central Gas Furnace

We all know how essential our furnace is to our homes. After all, without a furnace, you’d likely stay tucked under the warm covers and never want to get out of bed. 

And while furnaces are supposed to last up to 15 years, because we rely on them so heavily, they often experience some problems along the way. 

If your furnace is having an issue, the best thing to do is to call a furnace repair service.

Leave the problem for later, and you may end up having to replace your entire furnace. 

But, how can you tell if your furnace is having issues?

Check out this guide to learn the top signs you need furnace repair. 

1. You’ve Been Neglecting Your Furnace for Awhile

When’s the last time you’ve had an HVAC technician come over for a furnace a tune-up?

If you can’t remember, then that’s a sign that your furnace is due for its annual check-up.

Ideally, you don’t want to go more than a year without repairing your furnace. 

Wait any longer, and your furnace could breakdown due to minor, easily avoidable issues.

At the very least, your filter needs to be replaced every year. 

2. Your Utility Bill Skyrockets Unexpectedly 

Did your utility bill recently skyrocket?

If there’s no explanation for the sudden increase in your bills, then there’s a good chance that your furnace is to blame.

Basically, if your furnace is malfunctioning, it’ll require more energy to do its regular job.

This will translate to higher energy bills at the end of each month. 

So, if you notice a spike, it’s definitely time to call an HVAC technician.

3. Your Furnace Is Blowing Cold Air

Do you feel like no matter how much you tinker with your furnace, it just keeps blowing cold air?

If this happens, it likely means there’s an issue with the pilot light or the thermocouple.

As you might have guessed, these are complex components, and you’ll need to hire furnace services to deal with this issue. 

4. Furnace Blows Air Weakly 

Maybe your furnace is blowing air. But, is it blowing air so gently that you can hardly feel a difference in the temperature?

If this is the case, then you need to call a technician. 

A weak stream of air coming from your furnace could signal that there’s an issue with the fan, belt, or motor.

While an issue with the fan is relatively minor, an issue with the belt or motor is a big deal. 

Therefore, it’s important that call a technician right away. 

5. Your Thermostat Stops Working

Do you keep having to turn your thermostat higher and higher to heat your home even just a little bit?

If so, then your furnace is to blame. 

The main job of a thermostat is to let your HVAC system know the amount of heat it needs to produce.

If it suddenly stops doing that, then you have a problem. 

Your thermostat malfunctioning could have to do with electrical issues such as loose wiring, blown fuses, or tripped circuit breakers.

Due to the high risk of shock, it’s never a good idea to tackle these issues on your own. 

So, call an HVAC technician for help. 

6. Things Go Bump in the Night 

Has your furnace been making strange noises?

If so, it’s likely trying to tell you that it needs repairing.

Whether it’s a scratch, bang, or thump you’re hearing, it means something is wrong with your HVAC system. 

And, only a trained HVAC technician can identify and repair the issue before it gets worse. 

7. Yellow Pilot Light 

Take a look inside the front panel of your furnace. 

If the pilot light is yellow, then you need to call an HVAC technician immediately.

The light could be a sign that there’s a carbon monoxide leak. And if there is, you have a serious situation on your hands. 

Carbon monoxide leaks can be deadly, so make sure you keep out an eye out for the common symptoms of carbon monoxide poisoning:

  • Headaches
  • Loss of breath
  • Dizziness
  • Nausea
  • Losing consciousness 

If you suspect CO poisoning, turn your furnace and gas appliances off and get some fresh air immediately.

You should then head straight to the doctor or to the hospital. 

Then, make sure you have a qualified professional inspect your appliances. 

8. Water Is Pooling at the Base of Your Furnace

Water pooling at the base of your furnace is never a good sign. 

There are two substances that can potentially leak from your furnace: water and gas.

Obviously, a water leak is significantly less dangerous than a gas leak. 

However, both of these issues should be addressed if you want your home to stay warm and your furnace to continue working properly. 

9. Constant Cycling 

Do you hear your furnace kicking on and off repeatedly?

If so, this is a sign that your furnace is over cycling. In other words, it’s running way more often than it should be.

This problem could be due to poor air circulation, a clogged filter, or some other issue. 

The best thing to do is to call a professional for help.
