I have my inverter Daikin air con units serviced twice a year the guy strips them and cleans them and tops up the gas 500 baht per unit I don’t use them that much as I have Mr Ken ceiling fans AC to DC super quiet I live them on all the time my aircon units give me constant hot water supply throughout my villa my average government bill is 2/3,000 baht inclusive per month direct from PEA that includes service charge for my own 30kw transformer that includes swimming pool
A lot of the apartments on Samui you get you electricity bill direct from PEA REPLAY is a good example your monthly maintenance/ management charge includes all the outside area and the huge swimming pools it’s mainly the private properties that charge more and a lot of them like me have their own transformers which are not cheap to purchase and PEA charge a monthly fee
