The lifespan of a heat pump can vary depending on several factors, such as the type of heat pump, the quality of the installation, maintenance, and usage. Generally, a well-maintained heat pump is expected to last between 15 and 25 years. Here are some factors influencing the lifespan:

1. Quality of the installation:

   • A professional installation by qualified professionals contributes to the reliability and lifespan of the heat pump. Proper sizing and installation are crucial.

2. Maintenance:

   • Regular maintenance is essential to maintain the performance of the heat pump and extend its lifespan. This includes cleaning filters, checking refrigerant levels, and inspecting parts.

3. Type of heat pump:

   • Different types of heat pumps have different components and operate under varying conditions. Ground source heat pumps with a ground heat exchanger, for instance, often have a longer lifespan than air-source heat pumps.

4. Frequency of use:

   • The intensity of use of the heat pump affects the wear on the components. In regions with cold winters, the heat pump may operate more frequently, which can affect its lifespan.

5. Technological developments:

   • Technologies evolve, and older heat pumps may become less efficient over time compared to newer models. Homeowners may eventually consider upgrading their heat pump to benefit from improved efficiency and functionality.
