Hello guys today I’m going to share my experience with Hyundai HS4154.GCO-CM 1.5 Ton 3-Star Inverter Split AC. Really guys believe me when I bought this AC the dealer said that it’s a very good quality AC. But after using this AC approx 3 months max it started started making noise. The cooling performance is good but it takes more time than others. And it also takes so much electricity. After installing the AC our electricity bill got very high. I don’t like this product.
