When you have an efficient heating system, your home is more comfortable and stays at the right temperature throughout the year. Additionally, your home will be more durable over time because your HVAC system will not be working as hard. 

Knowing this, it goes without saying that it is paramount that you make sure your heating system is always at the top of its game. If you are not sure where to begin or if you have not had your heating system checked in quite some time, read on. Here, you will learn about some of the telltale signs that you may need to get your furnace repaired.

Unignorable Signs That Your Furnace Needs to Be Repaired

1 – Pools of Water Surrounding Your Furnace

If you notice puddles of water around your furnace, it probably is not a good sign. In fact, it could mean that you have a water leak. While the leak itself may be relatively simple to fix, it is something you will want to address because it could end up causing serious structural damage to your furnace and home.

Water leaks can cause Rust on your furnace as well as mould and mildew to grow in your home. Ultimately, your furnace will be something you have to replace as opposed to repair. The sooner you address the issue, the better.

2 – Weak Blowing Air

While you may not notice a difference in the temperature of your home, if you start to notice that the air coming out of the vents is weak, it could be a sign that your furnace is on its way out.

If the air is not being pushed out of the vents, there is no way to heat your home. This is why you should speak with an expert as soon as possible to see what the cause could be.

3 – Poor Air Quality

Another sign that your furnace may need to be repaired or replaced is poor air quality. If you notice that the air coming out of the vents is not fresh, or that your home is very dusty, this could be an indication that your furnace is no longer working the way it should.

Poor air quality can cause your family to get sick. Do not wait to address this issue.

4 – You Can See Rust around the Outside of the Unit

When you look at the outside of your furnace, you can usually tell if it is working properly based on how the outside of the unit looks. If you notice rust around the outside of the unit, this could mean that your furnace is causing damage to the pipes that are connected to it.

If the pipes are damaged, your furnace will no longer function properly. You will need to get these pipes replaced immediately.

5 – You Are Not Getting the Amount of Heat You Should Be

When your furnace is working properly, your home will be at the right temperature at all times. If you are noticing that you are not comfortable in your home when it is cold, this could mean that your furnace is failing.

If you have not had your furnace inspected in a while, you may need to have it looked at by a professional.


If you are noticing any of these telltale signs that your furnace needs to be repaired, contact a professional as soon as possible. While a minor repair may not be a severe issue, the longer you wait, the worse the problem could become.
