Ductless expert Jesse Claerbout talks about his best practices for maintaining ductless air conditioners and heat pumps. This episode is part 1 out of 2. Ductless maintenance can be a bit more extensive than regular split system maintenance.

Ductless filters are plastic; they are not high-MERV and can simply be washed off with water. Customers can clean their own filters with nothing but water from a hose or sink.

Blower wheels are a bit more challenging than filters; the blower wheels are long, have small cups that are prone to buildup, and carry an electrostatic charge. Due to the blower wheels' challenging nature, technicians require special training to deal with the additional labor, and customers require special education. As such, we at Kalos charge for special blower wheel maintenance. We pull the blowers from the systems and clean them (though the process of getting a blower wheel off the blower shaft is complicated). You can wash the blower wheel outside with a safe cleaner; make sure the wheel is dry when it goes back inside.

Removing the blower wheel gives you full access to the drain pan. During a ductless maintenance procedure, remember to clean out the drain pan thoroughly with a safe cleaner. If you clean ANY component indoors, use a drop cloth, especially if you're cleaning on carpet.

We clean evaporator coils and the housing with spray bottles (preferably) or pump sprayers. Clean WITH the grain, not against it, and use only water or mild, non-toxic cleaners. A botanical cleaner works well, especially for customers who may have allergies. Rectorseal also has a cleaning kit (Desolv) that comes with a good coil cleaner, a cleaning bib that surrounds the ductless unit, and a pump sprayer.
