Why is it that every installer talk down on Samsung air con? Their common complaints are hard-to-install, easily spoilt n difficult to get spareparts. Are these. True?

Why some installers claimed invertor air con can continue to use old concealed piping of R22 aircon? Only need to connect the joints. Some installers advised not to do this.

So it is safe to continue using old concealed piping of R22 aircon for new invertor air con ? Only need to connect the joints.

I already bought r410 invertor air con.

How to be future-proof if want to do concealed piping? And it would be costlier right?

kimsim I bought this RM5-filter from Daiso to use on my new Samsung 1.5hp-invertor aircon. I pasted the full-piece on top of the air-inlet as shown in the picture attached. Is this correct? A friend told me this will obstruct air intake and not good for the aircon.
BTW after install the Samsung 1.5hp(heavy-use) and a ME-GE24VA 2.5hp-invertor(light-use) aircons, my monthly TNB bill has dropped by ~25% or ~rm80.

After changing my 14yearold aircons, ME-1hp-noninvertor and PAnasonic-2hp-noninvertor with Samsung-1.5hp-invertor and ME-2.5hp-invertor. My monthly bill has come down to rm180 with heavier use. Used to be rm240-rm290. Aircon set at temp 28c is cooler than old aircon at 25c. Found that once the aircon is on, extending another 6-hr use will use another 3kWh. So envious of those household with <rm100 bill, how to achieve that? Would changing fridge(rm4000), washing machine(rm2000), LED lights, to energy-saving types helps? I think high-power-consumption appliances are like oven, kettle, iron might be the culprit.

How to calculate the possible savings by using a new invertor fridge? By changing from 1hp-noninvertor to 1.5hp-invertor my monthly savings already rm60/mth, by 24mths the savings of ~rm1400 would have cover the cost of installing the new aircon. If a new invertor-fridge can cut my electric-bill by another RM60/mth, 70mths savings would be equivalent to the cost of the new invertor-fridge.

TQ for your sharing. If can get savings of rm90 by just changing the fridge, payback time is only 4years, worth considering. Just browse thru the info on a few invertor fridges mentioned in this thread but found that most don't disclose the power consumption, wonder why? Will pay a visit to https://e-services.nea.gov.sg/els/Pages/Sea...am=goods&type=p

After playing around with d database/calculator at Spore NEA, I found that major electricity cost is from aircon, switching from 1-tick(rm55/mth) to 3-tick(rm35/mth) fridge doesn't save as much.

ME MUY-GE24VA 3-tick 6hr/day @53sen yearly=rm1284 (2422kwh, 6.63kwh/day)

Hitachi R-M700AGP4MSX(569L) 3-tick Refrigerator freezer 24hr/day@53sen yearly=rm250 (471kwh, 1.29kwh/day)
Hitachi R-M700GPMS(568L) 1-tick Refrigerator freezer 24hr/day@53sen yearly=rm 374 (704kwh, 1.93kwh/day)

I estimated that my current fridge(510L) is using rm480/year, rm230(rm10/mth) more than a new 3-tick one.

That is what I found out from Spore NEA too, invertor or non fridge doesn't save much electricity.

The diff btw 6-hr-non-stop and a 12-hr-nonstop usage of my 1.5hp-invertor Samsung 4-star aircon is only 2-3 kwh (or rm1.20). Same usage with my 5-star ME-GE24 will add 2kwh.

Already using d newly installed invertor aircon la. That is why can on for 6 to 12 hours as my child was having exam, and yet bill has drop by ~30%.

Change d installer. Others will be too happy to do it, less work same charges.

I think this applies to non-invertor aircon:

An oversized air conditioner is not good as the compressor will run and stop regularly and not able to cool the room uniformly. It will also cause discomfort to the occupants as the dehumidfication of the room is not properly done. On top of that, the electricity bill will be high as the compressor turns on and off too often.

Every time the on/off type of compressor starts to run, its power consumption is 6 times higher than when it is running steadily.

The cycling on and off of the compressor will lead to shorter life span of the compressor besides having to spend more on the unit price and installation cost.

I replaced my child's 140sq-ftx10ft-high room 1hp-non-invertor aircon with a 1.5-invertor aircon. Currently I set the temp to 28c with lowspeed-fan and it is as cool as the replaced aircon set at 25c. And the electricity bill has reduced by ~30%/rm70.

The current hot spell proves that Invertor Aircon is a better choice for long hours usage. I am so thankful that I replaced 3 units last year, otherwise my bill will be at least rm200 more per month and yet some days the aircons was on for 36 hours nonstop although set at 27C.
