  • How Long Do HVAC Systems Last?


  • May 1, 2021

    When you’re renting a house or apartment, you usually don’t have to worry about maintenance. Repairing appliances and critical parts of your home is generally not your responsibility.

    Once you own a home, you’re in charge of all repairs, remodels, and replacements. The roof, windows, floors, appliances, plumbing, and more become your responsibility to keep in working order. And as many homeowners know, this responsibility includes your HVAC system. 

    When it comes to investing in a new HVAC system, one of the top questions people ask is how long HVAC systems last. The answer is a little complicated since an HVAC system consists of many components. Keep reading below to learn more!

    How Many Years Do HVAC Systems Last?

    In general, HVAC systems can last anywhere from 15-25 years. For the HVAC system to last 25 years, it has to be a high-quality brand with good maintenance. Furthermore, an HVAC technician should inspect the HVAC system once per year.

    How Long Does Each HVAC Component Last?

    A well-maintained HVAC system can have a lifespan of up to 25 years. But your HVAC system isn’t a single appliance. It’s your heating system, the ventilation and ducts, and the air conditioner. Each one of those components will have different lifespans and need different types of care.

    Air Conditioning

    During the summers, your air conditioner is one of your favorite appliances. Generally, air conditioning units last 15-20 years with proper maintenance. Neglecting to change the filter or clean the coils can make the AC break down beyond repair within five to eight years after installation.

    Additionally, warmer environments tend to have more wear and tear on air conditioners. This is because they’re used more often. Homes near bodies of saltwater also tend to go through air conditioners more frequently. The salty air tends to be hard on air conditioners.


    A furnace must also be carefully maintained to last a long time. If taken care of, a furnace can last around 20 years. High-quality furnaces that have been well taken care of can last thirty years.

    Heat Pumps

    Heat pumps tend to break down around 10 years of use but can last as long as twenty years when maintained. The number of years that your heat pump lasts can also depend on your location and heat pump maintenance. With semi-regular maintenance and calm weather, a high-quality heat pump will probably last about 15 years.

    The best way to make sure that your heat pump lasts for a long time is to keep the coils clear of any debris or dirt and to replace your air filter often.


    With regular maintenance, the boiler will serve you well for 10 to 15 years. You must get your boiler inspected regularly by a knowledgeable heating specialist. Additionally, if you purchase a low-quality boiler, it may break down much sooner.


    Filters last anywhere from one month to 3 months. You need to change the filter in your air conditioner and furnace frequently.  In addition to regular maintenance, replacing your filter consistently has the greatest impact on getting the most out of your HVAC system.

    Get The Most Out Of Your HVAC System

    As you can see with most parts of an HVAC system, they tend to last about a decade to 2 decades. some parts may even make it to 3 decades. Ensuring that you get the longest lifetime possible out of your HVAC system relies on three important details:

    Professional Maintenance

    With professional maintenance, you can be sure that small problems will be caught and repaired before they become major issues with your HVAC system. Additionally, many warranties require that the system gets checked by an HVAC technician on an annual basis. Without professional maintenance, the manufacturer may not stand behind the product or warranty.

    Your Maintenance

    Professional maintenance will catch the majority of issues with your HVAC system. But it is up to you to make sure that the ducts are clean, the filter is changed regularly, and that the coils are cleared of any debris. Missing any of these could cause your HVAC system to fail much faster.

    Quality of Component

    Investing in a high-quality HVAC system and components for your HVAC system is one of the best ways to keep from needing repeat replacements. High-quality HVAC systems are manufactured with better materials and construction. Furthermore, they’re less likely to fail.


    Our home in the Inland Northwest is prone to frequently changing extreme weather. We can have snow one day, thunderstorms the next, and summer days in a week.  This rapidly changing extreme weather contributes to more wear and tear on your HVAC system. As a result, you may have to invest in a higher-quality HVAC system and dedicate time for proper maintenance.
