Ductless AC Ratings part 2, Reviews of the Acson, Actronair, Aermek, & Aeronik brands



This brand is made in Malaysia by OYL MANUFACTURING CO and is available in Europe, Asia, Africa, and Australia. The S SERIES offers basic units that use environmentally friendly R-410a refrigerant but they are for cooling only. 

The SIGNATURE SERIES offers units with changeable skins for the wall-mounted air handler. They have a built-in ionizer to improve air quality and the units are pretty quiet when operating. They can be purchased online through their website but the warranty on the units is not very good when compared to other brands. 

Acson Signature Series


ActronAir Serene Series

These heat pumps are made and sold in Australia.

The SERENE wall splits have coated coils to inhibit corrosion and are self cleaning. They have four way automatic swinging louvers for good air circulation and a "follow me" function where the remote control acts as the thermostat. They have DC indoor and outdoor fans for quiet efficient operating and a HEPA-bio air filter for improved air quality. The units are demand response enabled so that you can save money with PeakSmart options from electricity providers but their warranty is not as good as other brands on the market.

The MultiElite multi-split heat pumps can serve from two to five indoor units from a single outdoor unit and are backed by a pretty good guarantee.


This brand is a part of the RIELLO GROUP and the units are available worldwide through more than seventy distributors. The SE models are premium heat pumps with all of the standard features while the SK models also have Wi-Fi ability. The MKM range offers multi-split units with a plasmacluster filter for improved indoor air quality. They can serve from one to five indoor units with a single outdoor unit. Their website is not much help and does not have a stated guarantee for their products. 

Aermec SE Series


These air conditioners are made and sold in Russia. The LEGEND series offers heat pumps with inverter compressors and coated coils for durability while the STANDARD series offers lower cost basic units.

The units are distributed by CHERBROOKE but the guarantee is not very good when compared to other brands.
