How to know if your furnace is about to break

It's important to be aware of the signs that your furnace might be about to break. Knowing these warning signs ahead of time can help you avoid an expensive repair bill and a cold, uncomfortable winter! Here are some common signs that indicate your furnace may need to be serviced or replaced:

1. Strange noises coming from the unit – If you hear any banging, thumping, rattling, or other unusual sounds coming from your furnace when it’s running, this could be a sign that the fan motor is wearing down and needs replacing.

2. High utility bills – If your energy bills have suddenly gone up without explanation, it could mean there’s something wrong with your furnace and it’s not running as efficiently as possible.

3. Inconsistent temperatures – If you’re having trouble maintaining a consistent temperature throughout your home, it could be a sign that your furnace isn’t working properly and needs to be serviced or replaced.

4. Yellow burner flame – The flame of your furnace should always be blue when it is on. If the flame appears yellow, this could indicate that there is too much carbon monoxide in the air and your furnace needs to be checked by a professional immediately.

5. Age of unit – Furnaces typically last between 15-20 years before needing to be replaced, so if yours is nearing the end of its life expectancy, you may want to consider replacing it before it breaks down.

If you recognize any of these warning signs, don’t wait until your furnace completely breaks down to do something about it. Contact a professional HVAC technician as soon as possible to ensure your home remains comfortable and energy efficient throughout the winter months!

Just remember, if you take the time to pay attention to the warning signs that your furnace might be about to break, you can save yourself a lot of money and hassle in the long run. With a little bit of knowledge and some preventive maintenance, you can keep your furnace running smoothly all year round. Thanks for reading!
