Air Conditioner cleaning

[Nereus]

Well, I am now un-recommending Mr Too

I had exactly the same problem with him several years ago. At that time he was just a glorified pimp, as he himself knew nothing about air cons and on his own admittance, was completely dependent on one of his staff.

Well in fairness, he knows more now, as he usually turns up with just a lady who I assume is his wife. He has fixed various issues, including electrical stuff and he was always reliable. That bit seems to have gone. I assume the 'technician' was going to help him identify the source of the leak? Being a layman, the most obvious point would be where he pumps the gas in!

It is unusual, but not impossible, for a service valve to leak. The compressor is hermitically sealed, so unlikely to leak. The tubing joints are made using a flaring tool, and are always suspect. Both the evaporator and the condenser coils can be damaged by ham fisted cleaning, and leaks are very often difficult to find.

second that,Mr.Too is your man

Well, I am now un-recommending Mr Too.

Have a long standing problem with an aircon. A couple of weeks back he eventually came and did a full service, which was needed, but the bigger known problem, as already identified by him, is the gas leaking via an outside pipe or joint or somewhere!

He asked that we leave it a bit and then he would come back and fix the problem. But last Wednesday, he failed to attend at a time of his making in the afternoon and when I called, it range twice and the call was then ended. He turned up unannounced early the following morning and luckily caught me in. He added gas to the system and said he would call back on Saturday with a technician but failed to appear. In fairness the weather would have made it difficult to work outside.

But this time, my other half got involved and called him, as she has met and talked with him before, and he re-arranged an appt. for this morning at 10am.

Well, it's now gone 11am and he is not here. I called him 20 minutes ago, the phone rang twice and then the call was ended.

I will give him until the end of the day to see if he gets in contact and not knowing if the other recommendations speak English, will then ask my other half to call them and stop using Mr. Too.

sorry to hear that,never had that problem,but maybe my turn next

Thanks for that. He wanted to change the whole aircon system, but when challenged, he accepted the actual aircon and fan are in good working order (we have another aircon waiting to be fitted, but it's for somewhere else).

Anyway, it's not a major problem as the guest room is turning out to be very comfortable. The other half has taken control now and say's next time she is here, she will liaise with the other recommendations made here.

Me neither, hence my previous recommendation. He didn't turn up or contact me at all after I tried calling him. Last week when he did the same thing, he turned up first thing the next morning, so we'll see what happens. But I won't be calling him again. He has a coffee place now, maybe that is more profitable?

We had aircon refrigerant leaking in two of our units, all of which were fitted new when the house was built in 2011. As Nereus indicated, it was where the pipe had been flared to make a joint—presumably into the compressor on the outdoor unit. In any case, the pipework we had replaced was fairly poor and the flaring looked like it had been done with no more than a large screwdriver and the heft of a flip-flop! Even when it was re-done it still looked fairly shoddy. But it no longer leaked.

What's the make of these aircons that have sloppy pipe flaring and gas leaks? Is there a pattern that buyers of new units should be aware of that a few thousand baht saved at purchase may not be a good deal in the long run.

No, it has nothing to do with the make of the air con. The tubing between the outdoor condensing unit and the indoor evaporator, is supplied and installed by the contractor, in MOST cases. Some units are supplied with a tubing set, and even precharged with refrigerant. If the set happens to be the correct length, then it can be used, therefore using the factory flares. It is when Somchai attempts to either use the flaring tool incorrectly, or more likely, just attempts to
make a flare by hammering a tapered bit of steel into the tubing end.

There is a smell when we use one of our air con units.

We have raised this with our [Juristic Person recommended] service engineer who seems unable to resolve the issue [or even recognise there is a problem].

Can anyone recommend a good air con engineer who can come and look at it?

This has been asked a number of times - this was one last year so should still be useful


Mod Edit: Threads have now been merged.

The unit is Mitsubishi. Please could someone post the contact details for their service engineers. Thank you

I don't have it, hopefully someone does.

It very well could be a dead chingchoke (gecko). If so the odor will pass in about 3 days once he dries out. The little buggers do have a death smell much greater than their size!
