Window type aircon (inverter)

**oj88** · January 10th, 2021 09:03 PM

Seeking your opinions.

Many window-type A/Cs no longer has a drain hole. They deliberately flood the pan with condensate water to be splashed around the condenser to make it more efficient at dissipating heat (evaporative cooling). The downside is, the collection of water in the pan is a cesspool for bacteria, algae, and other gunk to form. It also corrodes the condenser fins and any metal it comes in contact with, particularly the metal parts that are constantly submerged.

Now, against manufacturer recommendations, I'm planning to drill a hole at the lowest point of the pan so that water will not collect. I'm aware that I'll be losing some cooling efficiency with the condenser bone dry... but if it means preserving the metal parts from accelerated corrosion, it will probably still be worth it.

What do you think? Good idea? Bad?

if i were me, i'd drill that hole.
but i would also take pains to beautify the hole and paint the edges of the hole, to prevent rusting.

The base is plastic so there's no treatment necessary.

I'm 90% committed to drilling a hole (maybe even 2 or 3 holes), I just went here for a sanity check. lol

well,
we can always re-seal the holes if the aircon proves to be too un-cool.

True!

ginawa ko na yan sa non inverter AC bro, 3 years na OK pa naman. nabenta ko pa last june 2020

Drill the hole ... have done it on a Carrier 1 HP non-inverter window type aircon ... still doing fine ... planning to do it on a Panasonic 1.5 HP inverter dual motor window aircon ...

^ I'm planning to. I'll do it once the A/C's installed. That way, I'll know where the water pools up.

Just have to be careful not to nick the condenser or any of the plumbing.

Just pull the unit a few inches away from your drill point on the housing. You'll be fine.

Does anyone has experience using an LG 1.5HP window-type inverter A/Cs?

The model I'm looking to get is LA150EC.

Feedback? Recommendations? Alternatives?
