The answer to 'how often to replace mini split' is that most mini split systems have a lifespan of 10-15 years with proper maintenance. However, the actual replacement timeline can vary depending on factors like usage, environment, and maintenance. As a general guideline, it's recommended to have a professional HVAC technician inspect your mini split system every 1-2 years and replace it when it starts showing signs of significant wear or reduced efficiency.
Regular maintenance, such as cleaning the filters and coils, can help extend the life of your mini split system. But even with proper care, these systems will eventually need to be replaced as components wear out over time. Waiting too long to replace an aging mini split can lead to more frequent repairs and higher energy bills, so it's important to plan ahead and budget for a replacement when the time comes.
