Most modern heat pumps should last you 10 – 15 years. After this period, it may be time for you to consider the more cost-effective option of a replacement. Heat pumps are mechanical devices designed to transfer heat from colder to warmer areas. This action makes them susceptible to wear and tear.
Here are some other signs that you may be better off replacing rather than repairing your heat pump:
- Constant need for repairs, even after a service
- Unexplained rising energy bills
- Unusual noises, such as cranking and rattling
- Inconsistent heat supply
