Heating, ventilation and air conditioning components like heat pumps are a major investment for most homeowners. When you're dropping thousands of dollars for residential climate control, you likely want to know how long heat pumps last and how you can get the most out of yours.

What Is the Average Lifespan of a Heat Pump?

Newer heat pumps can last from 15 to 25 years, depending on how well they're maintained, how you use them and the climate you live in. That's a step up from older heat pumps, which had average lifespans of between 10 and 15 years.

How Can You Extend the Life of Your Heat Pump?

Heat pump life expectancy depends on a variety of factors, including some that are within your control. Things you can do to help support heat pump longevity include:

Regular Maintenance

Professional upkeep is one of the most important factors in increasing heat pump lifespan. Have an HVAC pro conduct an inspection and tune-up for your system at least once a year. If you use your heat pump to heat and cool your space, consider having maintenance done in the spring, before warmer months set in, and in the fall, before the first ice, snow or frigid temps hit.

Choosing the Right Heat Pump

When choosing a new heat pump for your home, work with an experienced HVAC professional to select a system that's the right size for your space. Right-sized heat pumps don't have to work as hard to control temps in your space, reducing wear and tear. Professional installation also ensures everything is done right the first time, reducing issues later on.

Keep Debris Away From Exterior Units and Vents

Do a visual inspection every few weeks to ensure leaves, dirt, snow or other debris hasn't piled up around your outdoor unit. Avoid placing furniture and other barriers in front of vents inside your house. Heat pumps work best when air can flow easily through all the components.

Change Filters Regularly

Clogged filters make it more difficult for air to move through, making your heat pump work harder. Check the manufacturer's instructions for your heat pump, or ask your HVAC professional what the ideal filter-changing schedule is.

Protect the Unit

If you live in an area where your outdoor heat pump component may be exposed to extreme weather like heavy rain or snow regularly, consider putting a protective cover over it to reduce that wear and tear. Just don't tarp the unit or do anything that would obstruct airflow.

Outside Factors Impacting the Lifespan of Your Unit

Some things you don't have control over that could impact the life expectancy of your heat pump include:

Different Climates

Harsher climates can require heat pumps to run constantly, straining the system and causing them to break down earlier than they might otherwise.

Sudden Damage

A falling tree branch, debris in a windstorm and other damage can cause immediate repair needs and reduce the overall life of your heat pump.

Manufacturer Defects

Defects in your components can reduce the life of your heat pump. However, manufacturer warranties often help mitigate the costs of this type of issue.

What Are You Doing That Might Be Shortening the Life of Your Heat Pump?

Something many people do that could shorten the longevity of their heat pump is changing temperatures throughout the day. It might seem like a good idea to set the temperature conservatively while you're at work and kick it up (or down) to a more comfortable temp when you get home. But wide swings in operational temperature can cause your heat pump to work harder to catch up, leading to unnecessary stress on the system.

Overusing the emergency heat setting in the winter can also cause this issue. If your heat pump needs to rely on emergency heat often, it's probably a good idea to install a backup heat source.
