MHI quality is better and originally made from Japan/Thailand. ME is a sub brand from Mitsubishi itself to target residences market.

What's the installation will be like?

Pana technician said no leak? If the previous technician accidentally realease the refrigerant during installation then is impossible you get the cold air after your unit installed. Why need wait 3 weeks only you feel no cold air? Obviously there's a leak. And Pana guy just top up for you and never check where's the leak is. So irresponsible.

You have to know. Good technician isn't easy to find. Everyone knows how to install aircon. But very less people knows how to troubleshoot it. Because they don't know how to troubleshoot and will takes longer time for them to check. Plus no spare parts for them to test around. Mostly they will ask you to replace a new one because the pcb are costly to repair. Your this case most of the technician malas to layan. Haha.

Everyone is aware of China brand. Because market in China brand is low cost with high return is how they do business. But nowadays many things also made in China or get parts from china and assemble in their own country. But I would say China stuff is slowly picking up. Just don't expect much.

Is normal. The model you using is still York plant aka GA.

You need 2.5hp to cover this area. 2.0hp might enough for you. Still need to lookout the area for installation.

I have a customer clean it every 7 months. Same like your issue. High usage and turn on the fan while using your ac. Sorry to say. Your room is extremely dusty. Turning on the fan will get even worst.

You can't blame the Panasonic guy. First of all. What kinda cooling you need? If you think your previous York give you the cooling means you are looking for solid cooling. Seriously. R410 produce the cooling is lesser than R22. And r410 cooling is not solid at all. You just can feel cool. If you want colder than suggest to take bigger hp.

That app is useless. Still need to get a better guy who understands your needs. Temperature in a house will keep change so can't pick a hp is just nice for the room especially person like you. If you like fast cooling then inverter is not really your thing.

I assuming your sales person recommend you the wrong ac.

Btw. If you still get York instead of Panasonic. Whatever you said I don't think 1hp is enough for you. And then you'll think why the old York is much more better than the New York. And also. You moved to a new house.

I have a customer. Using 1hp room size at 8 x 8 height of ceiling is 10 feet. My dealer intro him 1hp says is cool until his balls drop. But after using for like 3 days. He says is not cold from the beginning. I came and troubleshoot the unit everything works good. I've told him 1hp is not enough for you. And then he rant. Since he rant I put a bet with him I ask him to replace a 1.5hp if is not cold and my previous statement isn't correct. I free for him. Ended up he paid for my 1.5hp aircon and thanks to me.

I understand sometimes end user doesn't have much knowledge that's the point we go and ask for their advices. But instead of giving you professional advice he/she has make own brand like a retard.

That's wrong. Customer priority comes first. Whatever customer needs we try our best to give them. If no stock we can wait. No need make the brAnd sucks.

Not so sure about this brand. If you are unsure and have doubt about this brand then suggest you to take extra $$ for a reputable brand etc like Pana Daikin or ME.

If is for rental usage and don't wanna spend a big buck then you can go for it. But pick the hp that suit the room. For rental wise, don't have to conceal. Just put a pvc casing to hide the pipes will do. Tenant just need aircon. Who cares is ugly. They more care if is cold or not.

Incoming to switch must be use thick

Switch to aircon must be use thick wire

Indoor to outdoor also same.

If thin wire and thick wires are connected it will result in burning. That's what we always see in the news.

What you meant is the cracking sound from the plastics? I have customer experience this before. Even I'm in the aircon field for many years I couldn't explain to them. More likely is like the plastic absorb the temperature too cold and then wen the compressor stop. The temperature starts a little warm then the sound appear.

Yes. Chemical will damage the coil IF not properly dilute. Or using acid will damage the coils. Safer way is use alkaline type of coil cleaners but use at mild solution and rinse with pressure gun. Brushing it is clean too but the inner part of coil is still dirty. Still suggest fully blast with pressure gun for optimum result.

80 is cheap. They could dismantle the outdoor to wash but at the price at 80 you can't expect much.

No. is not like this. Many people will think. I set temperature at 20 I could get 20 or some other brand offers you set to 16 but it couldn't get into 16 Celsius.

If a proper good condition aircon (not dirty or some other defects) outlet temperature from the louver you could get about 13 - 14 Celsius. When air blow out which can reach you should be + another 10 Celsius = 23 to 24 Celsius. Surrounding temperature would be different depending on the heat load in the room. If the temperature measurement from the aircon have no problem but your rooms doesn't get at least 23 to 24 (surrounding temperature) which means the aircon have defects such as need servicing or faulty parts or your aircon is underside.

Reason why the temperature maintain at 25 cause your compressor try hard to give you 20 Celsius. But once almost reach 20 the compressor cut off and then heat begin increase. After about 5 to 10 mins. The compressor kick in again and try to cool down and then repeat.

So I suspecting heat in your room is quite high.

You go for 2.0hp inverter. You're a person who looking for solid cooling. Achieving 20 Celsius in a room is kinda hard tho.

The sound you mentioning looks like the airflow not blowing consistent. Do check the filters first. Clean it and try again. If is still have the sound then check the blower wheel at the louver. Use a torch light to check if have dust and mold in it.

Bro. Not only none inverter need to replace the piping. All Aircon stated using R410A refrigerant need to replace the pipes. Good luck!

Usually the old Aircon I will donate to rumah orang tua or rumah kanak cacat. Some of them really tight budget in getting air-conditioning. Donate to them is helpful.
