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