How Long Do HVAC Systems Last?
As a homeowner, you've likely been asked at some point: "How long do hvac systems last?" While it's impossible to predict the exact lifespan of any HVAC unit, there are some things that you can do to extend its life.
Getting a new air conditioning unit installed correctly, maintaining it with yearly maintenance and making sure you get the proper size for your home are all important factors in determining how long a furnace, heat pump or air conditioner will last. Taking the time to research and find out the answers to these questions can help you make more informed decisions about your system's future.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) reports that central air conditioners typically last 15 to 20 years on average, but may last as few as 10 or as many as 25. They can also last much longer or shorter depending on the type of unit and the environment where you live.
If you live in a coastal area, however, your AC unit will usually last only seven to 12 years, due to exposure to saltwater. In these situations, it's best to replace your air conditioner whenever the compressor or condenser starts to develop significant corrosion and leaks.
The average lifespan of a heat pump, on the other hand, is 10 to 20 years, but it can last even longer when the right maintenance is taken care of. In fact, according to ASHRAE, most heat pumps can be upgraded to a more energy-efficient model, which can lengthen their lifecycles up to 30 years.
When Should I Replace My HVAC Unit?
If you’re unsure about whether or not to replace your HVAC unit, there are several things you can look for that will help make your decision easier. The first thing you need to determine is how old your system is.
A good rule of thumb is that HVAC systems can last 10 years or more if they’re properly maintained and installed. That means you should always hire a qualified HVAC professional to work on your system, especially if you’re planning a replacement.
Aside from the typical lifespan, there are a few other key factors to consider when deciding when it’s time to replace your HVAC system. If your air conditioner is over 10 years old or your furnace is over 15 years old, it might be time to start thinking about replacing.
Improper Installation or Size
If your HVAC system was improperly sized or installed, you should consider having it replaced immediately. An improperly sized system can leak deadly carbon monoxide into your home, cost you more money, promote mold growth that can lead to chronic illness and even cause fires.
You want your indoor and outdoor AC units to operate in tandem, and if you have an old or mismatched system, it may not be working as efficiently as it could. It also might not be able to properly maintain the temperature in your home, which will result in energy costs that are higher than you need them to be.
