Have you ever thought about how important your furnace is? You might believe furnace maintenance is simple, but many people put off doing it until it's too late. Not to mention that replacing it might be incredibly expensive.

It's critical to make a good furnace investment since when one breaks down, it can lead to several issues to your house.

Because furnaces consume a lot of energy to heat your home, it's crucial that you and your family seek ways to save money. Maybe you should think about changing your furnace as soon as possible if you're wondering how to prevent your utility costs from rising too much.

However, brand new furnaces are expensive, and is, infact, one of the most expensive parts of the house.

With this in mind, is it better to buy a used furnace? Will you really save money if you install a second-hand in your house?

You should ask yourself first the following questions when considering installing a used furnace in your home:

How Old Is the Furnace

The answer is, it depends on how "old" the furnace is that you want to use. Depending on use and the frequency of service, a furnace can have an average lifespan of 15 to 20 years. If someone regularly serviced their heating, ventilation and air conditioning (HVAC) system, their furnace could potentially have a lifespan of 30 years. 

You Need to Buy From a Trustworthy Source

This is also related to the first point. How will you know whether the furnace that you will buy is indeed less than 10 years old? Do you know if the furnace is not worn-out yet?

If you purchase a used furnace, get it inspected by a qualified technician, according to Debordinc.com.

We have a full guide to check whether you need to replace your old furnace, which you can read here. However, we will list down below the basic things you need to know for convenience.

• If you find that your furnace is making unusual noises out of the blue, it may no longer be functioning properly.

• If you notice that your electricity bill is increasing but you're still using the same devices, something might be amiss. An approaching-end-of-life furnace doesn't heat your home as efficiently. As a result, heating your home consumes more energy and costs you more.

• Your aging furnace might need to be replaced if you notice that certain areas of your home seem to be cooler than others. As your furnace ages, it could be more difficult to evenly distribute heat throughout your house.

• If you notice that the air quality in your home has gotten worse, your furnace might be getting close to its end of life.

• If repairs have been necessary for your furnace regularly lately, it could be time to replace it.
