Need some advises here.

Recently, my aircon is not cold anymore.
After checking the coolant is OK, the contractor claimed that the compressor PCB board is defective.

Replacement cost is RM710 (part + labor).
Is the price reasonable for Panasonic 1HP inverter aircon?

Anyone has recommended contractor?

Should I consider to top up RM400 to get a brand new Sharp inverter aircon with installation?

Current AC is about 4 years old and rarely used.
Just not sure why it can spoil suddenly.

Cost to replace the compressor pcb board is ridiculously high, any chance to get better price?

The outdoor unit is always in a well ventilated place with zero direct sunlight.
Perhaps you are right that the problem is caused by voltage spike.

I read somewhere that the compressor has 5 years warranty, perhaps I should call Panasonic.

No but regular normal cleaning service.
The coil area is very clean now, no wind blockage.

I can get a Sharp inverter model for less than RM1k too.

Panasonic informed me that compressor is covered by 5 years warranty but not the control board.

Hard to say, my current AC is Panasonic "premium inverter" model.
An equivalent new unit may will cost more than double and not to forget the installation cost too.
If the repaired part come with good warranty period, I don't mind to repair it.

earth.

You can read the manual on how to get the error codes.
If you are still unsure, please hire an aircon guy.

I'm surprise to see that you have green wire for neutral and red wire for ground.
Let's don't mess around as you are risking to destroy the aircon or harm yourself.
Please hire an aircon guy.

If you insist to try it yourself, make sure electric is switched off.
Then do this:

Indoor (top): The wire with power from grid
N: Blue
1: Brown (live)
Earth: Green

Outdoor (bottom):
N: Blue
1: Brown
2: Additional red wire in your picture
Earth: Green

The outdoor unit should have corresponding 4 terminals to connect like the "outdoor (bottom)" part.

I worried if you had destroyed the aircon due to earlier mis-connection.
Anyway, since indoor unit is up, you can check the error codes.
Please google to know how to check error codes with your remote.

Is the outdoor fan running?

Wiring colours are wrong.
Please follow my previous post instruction.

hi,

I'm looking for a good aircon contractor recommendations around klang valley.

My new house has all the inverter copper, drain pipes and wiring built-in.
No additional hacking needed.
No outdoor mounting bracket needed.

I find it strange when they are still charging the normal installation rates RM200 for 1HP, RM230 for 1.5HP and so on.

Zero material cost and purely installation labor only for 7-8 aircons.

Tried a few shops without luck.
All claimed installation is outsourced to contractors.

Please be aware that the mainstream inverter aircons are normally categorised as higher end model than the standard non-inverter variant.

The cooling capacity is also higher even the compressor is running full speed.
This means even the inverter dynamic speed feature has not kicked in yet, it already consumes less power than the non-inverter lower end model.

The inverter tech is already in the market for many years and this is NOT the only tech for saving electricity in aircon.
If your aim is to save electricity, an inverter aircon is the one to go regardless of any environmental factors if we are comparing the same HP units.

Of course, the next steps are to consider the correct size unit, house sealing and etc.

These are not good benchmark examples.
Although we are setting at 16C for both units but the cooling capacity is different. The key is the btu per watt. Higher end model (even inverter feature has not kicked in) has better efficiency.

In layman term, when we set to 16C, inverter Aircon may cool down the room to 20C but non-inverter can only cool down to 22C with the same power consumption.

Please try to compare again now.
Basically, non-inverter model has higher (50-130W) peak power consumption than other models.
That means even we run both in peak mode, users can enjoy better cooling experience and lower electricity bill.

The initial discussion was about saving electricity bill cost.
The purchasing cost was not considered.
If this has to be considered, please also factor in the gained features (fast cooling, ionizer, connectivity, etc) and experience (cooling effect).
Your formula can become (btu/watt + features + experience)/RM ratio.

The only cost concern is the part replacement for inverter models is significantly higher.
More features also mean more things can fail.
But this reliability can be subjected to brand, maintenance, installation, usage and etc.

Your problem can be solved by using Aircon windshield.
Just search for it in lazada/shopee.

Even without that, some newer aircons blade designs allow wind blowing at 90 degrees. Less direct blowing discomfort.

It's time to service your aircon.
