How Long Do Air Source Heat Pumps Last?

Home heating and cooling systems are expensive, so it's understandable that homeowners want their investment to last. Air source heat pumps provide an efficient and complete heating and cooling solution in one system, while traditional HVAC technologies require purchasing two separate systems, such as a gas boiler and an air conditioner. However, does the dual function of a heat pump shorten its lifespan? How long exactly does a heat pump last? This article will help you understand the lifespan of air source heat pumps and provide tips on extending their lifespan.

Air Source Heat Pump Lifespan

The lifespan of heat pumps is still debated, but it's generally believed that air source heat pumps last about 10 to 15 years—although some experts claim that a properly installed and maintained heat pump can last 20 to 25 years. Ultimately, however, the lifespan of a heat pump depends on the model, frequency of use, and maintenance.

Currently, traditional heating and cooling systems, such as gas boilers and air conditioners, may last a few years longer than air source heat pump systems. However, unlike these devices, we need to use heat pumps year-round. While gas boilers and air conditioners may have a slightly longer lifespan than heat pump systems, they require multiple purchases, leading to more subsequent replacements. Furthermore, heat pump technology is constantly evolving, so its expected lifespan is likely to continue to extend.

Air Source Heat Pump Maintenance

According to the U.S. Department of Energy, a well-maintained heat pump consumes 10% to 25% less energy than a poorly maintained one. Like other HVAC systems, air source heat pumps will decline in performance over time until replacement is necessary. However, proper maintenance can extend the lifespan of a heat pump and improve its efficiency—heat pumps should be maintained at least annually by a certified professional to check for blockages, pipe leaks, airflow issues, etc. For optimal system performance during the heating and cooling seasons, professional maintenance is recommended twice a year. In addition, home maintenance can also help extend the lifespan of a heat pump and prevent some preventable problems from escalating into more serious repair needs; regularly cleaning air filters and outdoor units can prevent airflow blockages, thus improving efficiency.

When to Replace an Air Source Heat Pump System

Even the best-maintained heat pumps will inevitably experience performance degradation over time. After fifteen years or more of comfortable temperature control, you may begin to notice signs that your air source heat pump system may need replacing. For example, rising energy bills and/or declining indoor air quality may indicate that your system's performance is deteriorating. Similarly, if your aging system requires frequent repairs, replacing it may be more cost-effective than constantly fixing malfunctions. To better understand the cause of any problems with your heat pump system and whether replacement or repair is the best option, it's best to consult a trusted installer.
