Window type aircon (inverter)

[dr. d]

Ang hina ng LG 1.5hp inverter ko ngayon, at around 8pm, we run it at full blast, high fan and 16c, mga 1 hour bago maging comfort cool level, before we can turn it down to low fan and 22c, room is 20 sqm, is it the heat? It's just 7 months old.

is your room insulated against external heat?
baka naman kasi, your aircon is cooling not just the air, but the walls and ceiling as well.
one won't get the air in the room cool enough, until the walls first cool down.
it takes a lot of time to cool the walls.

also, if i am not sure,
i'd see if the aircon needs cleaning.
after 7 months...

would you remember the EER number?
baka mas maganda ang EER ng dating aircon?
