Split Type Aircon: Which is best?

[vinj]

bought koppel 1.5hp mali ko lang dapat pala 2.0hp ang binili ko para katumbas nang kwarto naa almost 25-30sqm yung kwarto.

Non-Inverter sya... Ok naman ang lamig pero mabagal nga lang lumamig yung kwarto kaagad, after 30mins malamig na naman sya.

Additional Cost ko sa electricity for 5hrs a day na gamit nasa 1.2k per month.

Same mistake in our condo living room AC. Got a 1.5hp Panasonic. It cools okay but the AC is maxed out while a 2.0HP would cool it under less stress.
