Ductless mini-splits have a lot going for them. They’re quiet, efficient, cost-effective, flexible and comfortable.

And they have another major advantage over central air systems: Mini-splits systems don’t include lengths of ductwork where dust, mold and other contaminants can build up. A well maintained mini-split has the potential to deliver cleaner air to living spaces.

But just because there’s no ductwork doesn’t mean foul-smelling mold and bacteria won’t try to stake a claim on the system. Wherever there’s water, there’s the opportunity for mold.

You may not see it, but you can often smell it. A musty smell or “dirty sock syndrome” can indicate mold and mildew growth. And you know that mold and bacterial are more than just smelly –they can carry serious health risks.

The question is: What do you do about it?

Regular maintenance is the key. Or should we say superior regular maintenance. How you perform maintenance on a mini-split (or any system) can have a huge effect on future air quality and your customers’ comfort.

New to the market, our new Mini-Split First-Aid Kit resolves IAQ issues before they become problems. The kit offers two products tailor-made to mini-splits: Micro Coil Clean and Mold Control.

We’ve talked about Micro Coil Clean, which is perfect for cleaning the evaporator coils located in living spaces. It eliminates odor by eliminating mold, mildew and other fungi and bacteria.

But mold is like a weed patch or a pesky relative – you can get rid of it, but it isn’t long before it’s trying to come back.

That’s why after cleaning your coils we recommend following with an application of a fungistat/biostat. This proactive approach to cleaning helps prevent mold growth between maintenance visits. Mold Control, an EPA-registered fungistat and biostat, is the only product labeled for HVAC use while areas are inhabited – which is perfect for mini-split systems. It manages odor in ductless systems by inhibiting the growth of odor-causing bacteria, mold and mildew for up to one year.

And it’s versatile – it controls mold and bacterial growth in ducted systems as well. In fact, Mold Control is effective on most HVAC surfaces. It’s approved for use on cooling coils, air handlers, condensate drain pans, humidifiers and dehumidifiers, registers, grills, fans, sheet metal ducts, flexible metal or plastic ducts and more.

Providing cleaner air for your customers for months after your visit is just another way to differentiate your service.
