Deep Cleaning Your Mini Split System
Maximizing your Investment and your ROI (return on that investment) in your purchased Mini Split is the smart move. Here's one key way to help insure you get the most out of your new system, for years to come.
You are now (or are soon to be) the proud owner of a new, high efficiency mini split system. You've had it installed by a licensed contractor, not just to validate the system warranty, but also to give you the peace-of-mind that you get by knowing it's been professionally set up to provide you years of reliable performance efficiency and energy savings day-in and day-out.
You already know that in order for the system to perform at optimal efficiency, you need to clean the system's removable, washable high performance filter(s), on average every 1-2 months. That's a given... kind of like regularly changing the oil in your car. Cleaning the system filter(s) is a simple process that takes very little time, yet helps in maintaining / improving your indoor air quality. The caveat here is, as effective as these (and/or practically any) filters are, they have their own limitations as to how fine the particulates in the air are, with some of the most minute (microscopic) passing through the filters and then potentially building up on the internal workings of the system itself. So....
There is one other maintenance step that we strongly recommend you undertake regularly, for for your direct benefit and for the benefit of your mini split system's extended life. That step is, having your new system deep cleaned and sanitized, ideally by a professional heat pump system cleaning service with specialized equipment. Deep cleaning your system -- both indoor air handler(s) and the outside condensor-- will allow your mini split to perform at its peak, rated efficiency.
Why is that important, you ask? Well, it may not seem like much to you but... a 'micro-film' build-up of dust, pollen, and/or other microscopic contaminants may coat your inside coil over time. And when that happens, as little as one-fourth of a millimeter coating on the inside coil of your mini split can potentially reduce efficiency -- by up to a staggering 20%! That's about the thickness of 2-3 average human hairs! Losing up to 20% of the system's performance, and resultant energy savings, is a bad trade-off, when compared to the reasonably nominal cost for the cleaning. 
One other key benefit of the deep cleaning / sanitizing process is, the procedure is designed to also remove contaminants in and around the coils that might lead to mold growth. That's one more huge reason why initiating this process is a really smart move, especially if you are concerned with indoor air quality! Your high performance mini split system is designed to provide your with hears of reliable, effective service, not to mention substantial energy savings over that entire time. You've made a significant investment in making that happen, and you know with full confidence that you've made a sound long-term decision.
Don't be 'penny-wise and pound-foolish'... Do the smart thing. Protect your indoor air quality, your health and that of your family, and your 'personal environment comfort' investment by regularly scheduling an annual professional deep cleaning and sanitizing process. That little bit more you spend can benefit you in so many more ways than just dollars and cents.
