The Typical Lifespan of an HVAC System
Your HVAC system is the heart of your home. Just like your actual heart, your HVAC system must be maintained well to operate at full capacity. That’s why preventative maintenance is the key to its health and longevity. Whether you’re wondering what the expected lifespan of your HVAC system is or how to make it more energy efficient, we’re here to help. Check out the guide below to learn more about the average HVAC lifespan and more.The Lifespans of Common HVAC Systems
HVAC systems can last anywhere from 10 years to 50 years. It all comes down to the type of system and how well it’s maintained. If you remember to do things like replace the air filter every few months, clean the condenser coils, and seek repairs promptly when needed, your system will last for years to come. Let’s look at the average lifespan of different types of HVAC systems to help you decide what’s best for your home.Air Conditioners
Most air conditioners last between 15 and 20 years, although some may only last 10. The good news is that modern AC units are made with higher-quality materials and built for the long haul. But they still aren’t immune to the natural wear that comes with age. Factors that reduce the lifespan of an AC unit include:- Exposure to salty air, especially in coastal areas, given its corrosive properties
- A failed air compressor
- A leaky or corroding condenser
- Poor maintenance
- Dirty or loose parts
Furnaces
The average gas furnace lasts roughly 20 to 30 years when it’s maintained well—sometimes even longer—whereas poorly maintained furnaces only last 10 or so years. Oil furnaces usually don’t last more than 10 to 15 years because they’re prone to fuel problems. Even newer, more energy-efficient furnaces are susceptible to wear and tear along the way, especially when these factors are involved:- Leaky heat exchanger
- Dirty air filter
- Malfunctioning electrical components
- Faulty control switch
Geothermal Heating and Cooling Systems
A geothermal heating and cooling system is an eco-friendly alternative to traditional gas, oil, and electric-powered units. They use natural ground temperatures to provide homes with heating and cooling. Geothermal systems average 25 to 30 years, with some lasting as long as 50 years. Here’s what you can do to maximize the longevity of a geothermal system:- Replace air filters
- Upgrade your home’s insulation
- Clean air ducts
- Take advantage of the thermostat’s “auto” setting
- Remove debris and other obstructions from the outdoor unit
Boilers
Boilers typically last anywhere from 20 to 35 years, which is on par with most furnaces, if not slightly longer. If your boiler isn’t performing as it once was, a leaky heat exchanger may be to blame.Heat Pumps
Heat pumps have an average lifespan of 10 to 20 years, although it ultimately depends on how frequently the system is used and how well it’s taken care of. This type of system functions as an air conditioner and a furnace in one, producing both cool and warm air. Since heat pumps are used year-round, routine maintenance is even more important to maximize performance and longevity. Plus, maintaining your unit will help reduce repair costs over time.4 Signs It’s Time for HVAC System Repairs or a Replacement
