What happens if you don’t maintain your furnace system?

Home / What happens if you don’t maintain your furnace system?

If it is yet to happen to you, then you can be sure it will soon if you do not do the right thing. Your furnace starts misbehaving right in the middle of winter when you need it the most. It stops functioning entirely, and you are left with an expensive repair. That is when searching emergency plumber near me” Becomes your next option.

This frustrating situation is likely to happen to those who don’t maintain their furnace.  Apart from total breakdown, other things happen to people who don’t perform complete furnace maintenance. They include:

Increased utility bills

The furnace is like a car. If you don’t change the oil at the recommended time, it will not run efficiently as it should. As such, it is essential to ensure that every part of your furnace is working optimally. Grime and dirt can easily cause blockages.

There are also other parts that require lubrication regularly to run flawlessly. Ignoring such things will strain your unit and thus increase your utility bill in the long run.

Safety Issues

Furnaces have heat exchangers. This is what separates the air you breathe from the combustion process. The exchangers go through extreme temperature changes frequently, making it easy for them to crack. And if they do, dangerous carbon monoxide can quickly fill your home.

Another thing to consider is the particles and dust that you breathe in. A unit that isn’t properly maintained is likely dirty too. The debris and dust inside the unit will move with the generated heat to warm up your space leading to unclean indoor air.

Variance in temperatures

This happens in most cases due to “thermostat wars.” You will find that there are different temperatures in different areas of your house. One room is too warm, and the other is too cold.  This is caused by your unit’s blower not supplying enough air throughout your home because it has a coating of grime.

It may also happen because of holes in ducts or a calibration problem with your thermostat allowing heated air to move out through areas it is not supposed to.  Having the unit checked by an expert can reveal such issues that are pretty inexpensive and simple to fix before they worsen.

System breakdown

With proper maintenance and care, furnaces can last up to 20 years.  Just like a car, ignorance causes exacerbated wear and tear on various parts of the unit, and it may break down long before its life expectancy.  If dirt accumulates on mobile parts interfering with airflow, trouble will likely follow you sooner rather than later.

You can avoid all these problems with regular expert maintenance. The technicians will inspect it for any minor issues that can result in major problems or even total failure. And in most cases, an entire system breakdown usually happens on the weekend or at night, meaning you will be forced to pay more for emergency repair service.


Is there liquid flowing from your unit? That is an indicator of a major problem that you must take care of. Leakages are caused mainly by various issues such as a clogged hose, loose seals, broken condenser pump, or a blocked drain. Not resolving these issues can lead to more extensive and expensive damage in the long run. Contact our experts to inspect.

Bottom line

Furnace systems are mainly designed to make your home comfortable during winter. However, without proper maintenance, the opposite may happen.  As the owner, there are things you can do to keep the unit working optimally for a very long time.

Changing the air filter, cleaning the exterior, and checking for any leakages can make the difference. You will not have to search “emergency plumber near me in the middle of the night.
