I recently installed an LG Inverter V split type aircon 2HP, replacing my 1HP window type aircon that was underpowered to begin with. Grabe sarap ng lamig now. I sleep a lot better. Plus very quiet sya. So far ok na ok sya. I still have to see yun effect sa electric bill ko.
You could get your aircons very cheap at Sight and Sounds sa Shangrila. I don't know how the owner does it pero I get to save around 7k sa price versus mga popular appliance stores. At maasikaso pa sila.
