    Are you wondering what the average life expectancy of an HVAC system is?

    If so, then you should know there are two main things that typically determine this. If you want to find out what they are, then continue to read on.

    1. Maintenance
      Maintenance plays an important role in how long an HVAC system will last for. A few of the most crucial maintenance tasks include changing the system’s filter every 1-3 months, as well as giving your system a tuneup maybe once per year. Other maintenance tasks include going to the outside unit and removing dirt and debris that has accumulated on it. Replacing the system’s refrigerant insulation is another maintenance task that can ensure an HVAC system will last for as long as possible.

    Average Life Expectancy


    About 15-18 years is how long you can expect ah HVAC system to last for, with no maintenance performed on it at all. If you don’t do any of the previously mentioned maintenance tasks, then chances are your system will last for around 15-18 years. Bear in mind this is just an estimate, but it could last longer or even less than that.

    With a little bit of maintenance, then a system can easily last for between 18 and 20 years. By performing a little maintenance, we mean doing 1-2 of the previously discussed tasks. If you change the filter regularly and you give it a tuneup from time-to-time, then your system could go for 18-20 years.

    With a bit more maintenance, a system’s life expectancy can be between 20 and 25 years. This would mean you’d need to perform at least three of the maintenance tasks mentioned earlier. By doing that, your system might last at least two decades or a bit longer than that.

    By performing maintenance regularly, and by doing all of the previously discussed tasks, then your system could last for 25 years. It many cases, it’s life expectancy could be longer than that. It all depends on how much maintenance you perform and a few other factors.

    2. The Brand
    The brand of the system also factors into how long an HVAC system will last for. Some brands are known for producing equipment that lasts longer or not as long as other manufacturer’s HVAC systems. As a general rule of thumb, if a company is very reputable, has many positive reviews written about them throughout the last few years and they are known for their quality systems, the chances are their HVAC systems will last for a very long time.

    Remember, name-brand systems have a good reputation for a reason. Plus, many of them have a lengthy warranty on their systems. This is further proof that their HVAC systems are built to last.

    As you can see, the average life expectancy of an HVAC system is 15-18 years, but that’s without any maintenance at all. The better you take care of your HVAC system, the longer it will last for. It doesn’t matter what kind of HVAC system you decide to buy, make sure you take good care of it.
