Hi Rishi, After remaining indecisive regarding selection of inverter AC between LG BS-Q186C8R2 and Sharp AHXP-18MV finally purchased Sharp AHXP-18MV today.
Congratulations for the purchase. May you enjoy long years of cooling bliss.
Although Cooling range and EER of LG model is marginally better but input power is higher than the Sharp model. Further the manufacturing defect in the OD unit in case of LG as posted on several threads has also been a deterant.
I am quite sad at LG's current build quality. It seems LG have dropped their Inverter AC's product quality from BEST to WORST in no time with a hefty reduction on price. It has been just about a year and a half that my friend got the LG 1.5 Ton (BS-Q186C7M1).
The older 1.5 Ton LG Inverter (Model No: BS-Q186C7M1) unit over which my previous assessments were based used to be 10 grand costlier than this new model and had much better build quality with no issues. My friend is super happy with this old unit. The indoor unit also used to be much more advanced than the current one in having double horizontal louvers to precisely control airflow and many more types of advanced air filters were provided. It also used to come with free installation kit.
The current models IDU is more of a knocked down version of the former model in having a single top hinged horizontal louver and Plasmaster. It seems a copycat of the unique top hinged louver topology of Sharp along with its Plasmacluster. Also it does not come with installation kit any more.
In other words LG have cut corners to be in the competitive Inverter market. Though LG have slightly better performance than Sharp in the 1.5 Ton category, no more can I say they come with equal built quality. We have seen issues with broken louvers of IDUs. Almost every forum member here or in other forums are facing some kind of manufacturing or design issue where the ODU fan grill is touching the fan which amazingly persists in almost all their current Inverter models and in extreme cases busted new ODU's !!!
Can you throw some light on the installation regarding the lenght of pipes from ID to OD unit . Is the whole lenght of Cu pipe provided in the kit is to be used or can be reduced if site conditions permit. Else if they are rolled and not cut will it affect the cooling.
The pair of refrigerant pipes as provided is of 4 meters in length. Ideally the pipes should traverse the shortest distance from IDU to the ODU having minimum number of bends. Shorter lengths are better. That being said the minimum pipe length for Sharp AH-XP18MV is 1 meter while the maximum chargeless pipe length can extend to 7.5 meters. Do not roll the pipe. Cut it to the minimum desired length required which should be between 1 ~ 7.5 meters.
