decca60 Posted August 30, 2017 Share Posted August 30, 2017 Hi everybody Here in Jomtien, two weeks ago I had one AC checked, small leak which was fixed, all unit desarmed and cleaned up, recharge, all for 800 bahts.

If he finds the leak, assuming its coming from the copper pipe, then he can sort it and refill for a 1,000 baht which in my opinion would be about right, i.e. whats the labour charge for a days work, tops (300 baht), and the gas refill (500 baht), allow for copper piping (200 baht), one can then justify the 1,000 baht. Will investigate further before going for the refill, I think Bankruatsteve in his reply is on par to what I am thinking, i.e. 500 baht in the village, 800 baht I think is a little high personally, but depends if you live in the city or the village, add for labour and parts if any and I think the 1,000 baht is justifiable, thanks to all. You make me laugh. You say 300 baht TOPS for a days work. Why not just offer him a bowl of rice and some monkey nuts. Link to comment Share on other sites More sharing options...
pauleddy Posted August 30, 2017 Share Posted August 30, 2017 I stick to a regular bloke and his team. The gassing (fluon??) is part of a service where he will clean inside and check compressor. I pay about 800. If he does my smaller new one in the bedroom, about 1000 for both. Link to comment Share on other sites More sharing options...
rwill Posted August 30, 2017 Share Posted August 30, 2017 I pay ฿500 per unit for cleaning service which includes checking the pressure and topping off refrigerant if needed. I have yet to see any service person that uses an electronic leak detector here just dish soap. Link to comment Share on other sites More sharing options...
Dazinoz Posted August 30, 2017 Share Posted August 30, 2017 Obviously it's a Thai thing and people just accept topping up the gas. If done properly it should NEVER need topping up and if it does require it then it has a leak and needs to be repaired. I had a split ac system in Australia fir 18 years and never needed topping up. I put a new inverter in and I moved 18 year old one to work shop and ran another few years and was still running when I left. Link to comment Share on other sites More sharing options...

The very act of measuring the pressure will cause a small gas loss every time it is done. Over time that would probably amount to enough of a loss to need topping up. I'm fairly sure that is what has happened to mine anyway, based on the fact that it loses the same amount of pressure every year but has not yet been topped up.

They do a decent job on the inside unit (radiator, drip tray and rotary fan - the latter is dismantled and cleaned outside) and an acceptable job on the outside unit, and they also clean the drain pipe. But I do always watch them like a hawk and if they look like they are about to "forget" something I dont hesitate to remind them. The outside unit is the one that is most likely to be "forgotten".

George FmplesdaCosteedback Posted August 30, 2017 Share Posted August 30, 2017 Recently had 2 done for ฿1,000 in Bangkok Condo. Thing is we have had leaks from the A/C unit condensation pipes and some actually dripping out of the units themselves on and off for a while and all the "Tech" guys would do was clean them and 6-8 weeks later it started again. They are about 6 years old. I got some new guys and they reran the pipework and blew it through and cleaned it too, along with everything off the walls and in bits sprayed and cleaned. One Unit wasn't blowing cold so they came back and fixed it for free. Seems fine now on that score. We will see how long they work for... Link to comment Share on other sites More sharing options...

That sounds like exactly what used to happen with my unit when they didnt flush the drain pipe correctly. Once they have been done properly you could try my vinegar solution method which I find very effective at keeping algae at bay. Link to comment Share on other sites More sharing options...

jacko45k Posted August 30, 2017 Share Posted August 30, 2017 On 8/27/2017 at 11:16 AM, Lamkyong said: they only top them up with the amount they loose during the diagnostic procedure no test no loss unless of course there is definite symptoms of a leak or as suggested icing up Then testing for loss of coolant is causing loss of coolant?? They should not need testing unless the unit is not cooling or is freezing up, that may also suggest a leak which needs to be addressed first. One of mine needed to be refilled after pipework was replaced and it cost under 1000 baht. My usual service really only involves cleaning of the inside and outside units with water. This is not something I can do myself as they use a bag device on the indoor unit and there is some disassembly done. There is every likelihood they will make up a (falang) price which includes some profit for them, but once sent home you will likely be subject to some minimum charge for the next visit.

themerg Posted August 31, 2017 Share Posted August 31, 2017 Get it serviced from where you bought it. They will come to your house, usually 2 people. The cost is : 500-800 Baht. Link to comment Share on other sites More sharing options...

Our regular guy never charged for top up, for clean 500 for 1, 800 for 2, 1000 for 3, 1300 for 4. That's good, your guy must have an MBA! I wish more would: the other day I saw a pick-up selling some fruit: 3 kg - 50 baht, 5 kg - 100 baht. I bought two 3kg bags, gave him 100 baht and he seemed happy?

transam Posted August 31, 2017 Share Posted August 31, 2017 Does the gas have a lifespan....? Link to comment Share on other sites More sharing options...
Dazinoz Posted August 31, 2017 Share Posted August 31, 2017 Does the gas have a lifespan....?I don't really know but I think the ac itself will end its life before the refrigerant. As mentioned before mine was 18 years old before I changed to an inverter type and then I moved the old one to my workshop with still the same refrigerant. Lubricating oil travels around the system with the refrigerant, hence you will often see oil at the site of a leak. The oil is probably more likely to break down than the refrigerant. The newer refrigerants use a synthetic oil which is hydroscopic meaning it absorbs water easy. If the ac is not vac properly on installation moisture in the air is trapped in the system, absorbed by the oil and forms an acidic compound and eventually corrodes ac components. Very important to have newer ac units using refrigerant such as R410A to be evacuated properly. Link to comment Share on other sites More sharing options...

Why not just offer him a bowl of rice and some monkey nuts. Laugh as much as you like mate, for your information, the new guy took the unit away, soldered the leaking joint, refilled and reinstalled the unit and charged 800 baht as quoted, that's half what the other dipstick quoted, all done within 3 hours, and I gave him the 1,000 baht which I offered the other dip stick originally. The new guy was happy as, and I am sure he will be eating more than what you suggested I offer him, so don't see your stupid point in offering him a bowl of rice and some monkey nuts, try to remember, or should I remind you that we are in Thailand and things are much cheaper than in farang land, which is why we can afford to live her, and doesn't necessarily mean we have to fork out farang prices, unless you want to blow your money quickly and have to move back to farang land, if your loaded, which I doubt, and want to feed them seafood, washed down with a nice bottle of 1993 Don Perignon Brut, then go for it, but I doubt you would be so inclined.

I think this depends on whether you live in a village or in a City, in Issan, the going rate is 300 baht a day, although some out of villages will try to charge more, i.e. had been quoted 250 baht and 160 baht per metre to install 75 metres of VC guttering, which included down-pipes going into pits, so a little digging, but we ended up paying 60 baht a metre, pays to shop around.

mogandave Posted August 31, 2017 Share Posted August 31, 2017 Does the gas have a lifespan....?No. That said it can be contaminated, and may be more costly to recycle than to replace. I can't speak to the oil, but it in an ideal environment, without dirt and moisture.It is not unusual for industrial units to go 30 years, and they routinely go twenty.
