why not just take out the rotor and clean that? thats what i do. take out is 3 min. cleaning outside 5 min, put in 2 minutes - done. just brush a bit the coil while its open and wipe the plastic also - add a few minutes. all in less than 15 minutes.

second that, my house is single phase and has:

1x 2 HP
1x 1.5 HP
4x 1 HP

can even on the oven as well no problem. of course all direct DB wired.

whatever amount of cooling you need you need to convert electricity to cool air for it. so to minimise electric bill set the temp as high as you can still stand. everything else will not help. further savings: use inverter instead of normal a/c. further savings: close all drafts (windows, doors, ceiling), further savings: get better windows, insulate roof/ceiling, paint walls white outside, use reflective paint, plant vegetation.

try to clean the blower fan (take out for quicker results) and also brush the condensor fins. spray outside compressor with a soapy cleaner let it soak for 5 min and hose down. then see if you have cold air again.

i have good experience with joo-fen A/C if really need to service i call them.

normal pricing. if you got many a/c then can barter for discount.

yes and no. it wont use less power for 1 BTU cooling BUT dryer air feels colder and mor comfy. that is why you dont need to set ac so low = save money / energy.

free gift? I also want so Urusara 7 still around 4xxx RM? was hoping the price would drop by now.

You can calculate yourself:

Get the difference in price difference first.

Then calculate power consumption for non-inverter (avg. for your place - get real data!) and multiply by hours you use x 365. There is your annual cost for non-inverter.

Next multiply that number by 0.6 then you have the cost for electricity for inverter (roughy).

Now consider two things:

Maintenance: can be cleaned by yourself or outside. Cost should be the same because AC wont loose gas unless something is wrong. No reason for inverter to be more expensive than non inverter. So cost is the SAME.

Parts: You can check. But in all honesty things rarely get spoiled besides maybe the fan motor after many many years.

Lifetime: An inverter can usually last a bit longer than non-inverter due to the lower stress level on compressor and motors (no on/off all the time).

Reallife figure: Inverters after 8 years still no problem. And that is 8 years of 24/7 usage! My non.inverters after 6-8 years (24/7) usually got problems and needed to change. You could assume that they can probably last 2 years more easily or 25% longer lifespan.

This means the annualised cost for and inverter is price/10 and for non-inverter is price/8

take those two numbers. comparison starts now:

annualised cost inverter: purchase price / 10 - (!!) electricity cost non-inverter + electricity cost inverter
annualised cost non.inverter: purchase price / 9 + electricity cost non-inverter

see which number gives you personally a better result (lower number = better) and there you go. its not rocket science but a simple calculation that anyone can do.

no problem besides the power cost. i have my acs on for 8 1/2 years non stop (besides a regular maintenance). i just never off them at all. no harm.

your electrician is right. pana is reliable, low maintenance, easy and cheap(!) spareparts. been using first gen inverter for 8 yrs 24/7. out of 6 units all are still totally OK, two got the inner fan motor changed due to being noisy. not hard to change, can buy the motor yourself and change. pana charged me like 150 for the motor. good deal. also those units you can service yourself which saves a ton of money. no need to call anyone.

i would not say famous. its from turkey (not in the EU) and frankly speaking their stuff has some looks but lacks the quality. its like pensonic vs. panasonic. i have yet to meet someone with a great experience on their products. i only hear so-so comments and complaints.

sorry but no. nobody in europe actually uses beko. i live partially in berlin and absolutely nobody would buy beko in germany. for aircon i would stay away from beko just as much as any other el-cheapo brand.

why should it? no problem to put to 30° either if you like.

nope. just work less. aircon doesnt really care. you use it less you have less risk of spoling. only old style maybe got problem on/off too much. inverter will be your friend.

Need to replace my aged insulation foam. Where do you guys get a good one in KL/PJ?

cool thanks! I was hoping i can get the jacket type somewhere so i can remove and replace. will try them later today or monday.

that is also nearby - cool many thanks. i almost ordered this from lazada (https://www.lazada.com.my/m-d-building-products-50164-1-inch-by-6-feet-self-sealing-tube-pipe-insulation-53001801.html?spm=a2o4k.searchlist.list.8.3b81eaa8FJwB6C) but i will check those out.

this is great. thanks a bunch. I only want to replace the outdoor insulation for now - indoor not accessible. next round of installation i will get my own insulation and give to installer

of course not. just lack of standards. for a new installation i would also ensure its done that way - just when i did it 10 yrs ago i didnt know. well you learn on the way.
