The short answer to this question is yes.
As with any appliance or equipment that we purchase, we should always perform some form of maintenance on them.
Your car, your phone, your laptop, your refrigerator, your home, just about anything we own or use needs to be maintained in some way. Regular maintenance of these items will not only guarantee that they are functioning properly, but it also helps to extend the life of them as well. So, just like any traditional HVAC unit needs to be maintained on a yearly basis, the same rule applies for the ductless mini split A/C. And though the ductless is a smaller and more compact unit than the traditional heat pump, the maintenance is pretty much the same. Maintenance for a ductless mini split A/C includes changing the air filter, cleaning the condenser coils, cleaning the drain pipes, as well as cleaning any debris away from the outside portion of the unit. While this might sound like a lot of upkeep, the good news about a ductless mini split A/C is that you don’t need to pay a professional HVAC technician to perform the service. Just like how you can install the unit without professional help, none is required for the maintenance. This means, using a ductless mini split A/C unit will certainly save a few hundred dollars each year. In no time, that ductless mini split unit will pay for itself. So, yes, it’s recommended to perform annual maintenance on a ductless mini split A/C as it will help with the overall performance of the HVAC unit.
