There are several reasons to have your Ductless Mini-Split system tuned-up twice a year. By keeping your system well-maintained, it will be able to heat and cool your home more efficiently. A poorly maintained system is between 10% and 25% less efficient than a well-maintained one. This helps keep your electricity bills down. Your system will last longer with regular maintenance. With maintenance, it can last up to 20 years. Another benefit is that you’ll have reduced repair costs. Small issues can be caught during maintenance before they turn into large repair bills in the summer or winter. Your home having better indoor air quality is another benefit.
