The answer to 'how often to replace heat pump' is that most heat pumps last between 10-15 years with proper maintenance. However, the actual lifespan can vary depending on factors like the quality of the unit, how often it's used, and how well it's maintained. As a general guideline, you should plan to replace your heat pump every 10-15 years to ensure reliable heating and cooling performance.
Regular maintenance like changing air filters, cleaning the coils, and scheduling annual tune-ups can help extend the lifespan of your heat pump. Signs that it may be time to replace your unit include reduced heating/cooling efficiency, increased energy bills, and more frequent repairs. If your heat pump is over 10 years old and starting to have issues, it's a good idea to consult an HVAC professional to evaluate whether replacement or repair is the better option.
