How Long Do HVAC Units Last?

The average lifespan of a home heating and cooling system is 10-15 years, but it’s possible to get up to 20 years out of one with proper care and maintenance. Here are some tips for keeping your HVAC system running at peak performance for as long as possible.

Factors That Affect Life Span of Your HVAC

The life of a heating and cooling system depends on several factors as follows:

HVAC Unit Size

When it comes to the lifespan of your HVAC unit, size matters. Not all HVAC units are created equal. If you have a smaller home or apartment, you may be tempted to purchase a unit that is too small for your space. On the other hand, a larger unit could be an overkill for a smaller space. Not only will your HVAC system last longer if it’s the right size for your room, but it will also work more efficiently and evenly distribute warm air throughout your space.

Home’s Insulation

Your home’s insulation is the key to a long-lasting HVAC unit. The insulation of your ducts, pipes, and walls determines how much energy your HVAC system uses during operation. In other words, the better insulated your home is the lower your utility bills and the longer your HVAC unit will last. No one can tell you exactly how long your HVAC unit will last, but if you’re doing everything you can to extend its lifespan, it may last anywhere between 15 and 20 years.

Humidity Levels

Many people don’t realize that the level of humidity in your home can have a major impact on the lifespan of your HVAC unit. If you have a dehumidifier, it will remove excess moisture from the air, which helps to prevent mold and mildew growth. However, if you aren’t using one of these units, then you should keep the humidity levels in your home between 40% and 50%. If they are much lower or higher than this range, then you could be putting undue stress on your HVAC system.

Regular HVAC Maintenance

Regular HVAC maintenance is probably the most important aspect of owning an HVAC unit. It ensures that your home or office stays comfortable and that there’s minimal downtime in the event of a serious problem with your system. If you don’t keep up with regular maintenance, your air conditioner will be more inclined to break down during peak season when you need it the most, and repairs can be costly. Also, if you neglect routine servicing and cleaning, the indoor air quality in your home or office could suffer.

Proper Installation

If you want to keep your HVAC unit in good shape for as long as possible, you must know how to properly install the unit. This is one step in ensuring that your unit will work efficiently for a very long time. You should identify where the unit is going to be placed. You should have your contractor or other professionals help you with this if you’re not already familiar with installing an HVAC system. You need to make sure you place your unit in the right spot so that it can do its best work.


HVAC systems are one of the most important features in a home. If you have an HVAC system that’s not performing up to the mark, it can cause serious problems for your wallet. To ensure that your system is working at its best, schedule routine maintenance checks with a professional service provider.
