I have 4 Mitsubishi Electric aircon units in need of service in the extreme south of Khon Kaen province, 80 km from KK city.

Anybody have any good contacts in that area?

All have been thoroughly cleaned annually by the local bloke & I do the routine stuff myself every 6 weeks or so but now the performance is dropping-off & I'd like the gas checked & topped-up if necessary in the heavier-used units. The local servicer doesn't appear willing (or able?) to check & he certainly hasn't got a set of gauges with him when he visits.

3 of the units use R22 - is this still available in Thailand?

Thanks.

In Ban Phai, Open home is providing this service and they have good engineers.

It will cost you about 500baht per unit, but again don't know if they operate in Phon.

I'll try to get their number and PM it to you.
