Our Top Tips on How to Make Your HVAC System Last

Whether you’re planning to have an HVAC system installed or you already have one, one of the most important points you must know about it is how long it will last. Seeing that an HVAC system is an investment, and you will want to ensure that it can overcome the test of time. If you have a system that breaks down regularly or requires continuous repairs, then it will not serve your family well.

In this post, we will talk about the HVAC’s average life expectancy and what you can do to make it last longer:

Average Life Expectancy

Know that the average life expectancy of an HVAC system is between 15 and 20 years. You may even encounter manufacturers who claim that it can last for 25 years. However, the truth here is that the length of your system’s capabilities will highly depend on you. For this reason, you can make it last as long as you want to if you invest in reliable maintenance works. 

Factors That Affect Life Expectancy

To make your system last longer, you need first to know the factors that affect its lifespan. Here are three factors to keep in mind:

  • Maintenance: It’s vital to keep your system clean and efficient, and you can’t do this by wiping it or making sure it runs well every day. It requires high-quality maintenance performed by an HVAC contractor regularly. If not maintained properly, it can compromise the life expectancy of your system and result in issues that will lead to costly repairs or replacements. 
  • Moisture levels: If there’s excess moisture in the system, it can compromise its components, which will make it rust or breakdown or both! 
  • Installation: If the HVAC system was not installed properly, it will have a higher chance of experiencing premature breaking downs. Because of this, it’s essential to only have a professional install your furnace instead of performing it by yourself. 

How You Can Make Your System Last Longer

If you want your system to last longer, you need to ensure it gets regular maintenance. We can’t stress this enough; having a trusted HVAC company––such as Donaldson Heating––to work on your HVAC’s regular maintenance is essential. 

The chances are that you will only choose from local service providers. With that, ask for referrals from neighbours and friends who live in the area because they are the ones who may have the first-hand experience. However, keep in mind that it’s still more important to work with someone you’re comfortable and at ease with instead of choosing someone because a friend told you to. 


At this point, you now know that making your HVAC system last is not impossible. However, the minute that it is installed in your property, you are fully responsible for it, meaning that you can determine how long you want it to last. Aside from proper maintenance from an expert, there are still several maintenance checks you can do by yourself, such as checking the filter, the ducts, and even cleaning its exterior. 

Ask your contractor about preventative maintenance you can do to help make the system last longer. After all, this system doesn’t come cheap, which is why you must make it worthwhile to get the most out of your investment.
