Hello there! I have been using this Air conditioner for more than 3 months and I am not very happy with its performance. My room has an area of 150sqft approximately and it takes about 7-8 minutes to get cooled a little. I have to wait for 15 minutes to get satisfactory cooling. The sound is not much irritating but it does some sort of vibration-like sounds.
Apart from this, there are a lot more problems like its service. This AC needs to be cleaned every 25 days otherwise you will be running an AC which just consumes electricity and does no work. I am not sure if all the AC’s from Panasonic are like this. Some may be good.
I finally warn you to think twice before buying this product.
