Click To Read Reviews


Build Aspect

Enzen 3100S / RSNS317HEEA is a budget Air Conditioner from the stables of Hitachi. This AC is not a premium offering like their 5100 series and therefore it is likely that there are some corners cut to make it affordable. Having said that the AC looks every bit as premium as the higher-end series and moreover this AC looks one of the better looking units in this price range. Furthermore the quality of plastics and build quality is very good. Its only when its put through the scales we see that the higher end models are more heavy owing to competent compressor and fan blower.

Performance Aspect

The RSNS317HEEA is a 3100S series split AC, packing 17400 BTU under the hood. While it is certainly a bit under power this unit is far from being under powered. Its effectiveness is felt within a short span of turning it on and additionally it has got a sufficiently good air blower, which has got a good draft. It was surprising to note that the noise levels indoors at low fan speed touch 36 db. All though it is not troublesome loud it certainly felt disturbing when absolute silence was needed. When we think that this AC also lacks a 4 way swing, we start to lose focus on whats good. That is when the attractive price comes into picture. So this AC while has its own sets of positives and negatives, it definitely is a good buying considering its a Hitachi.
