Working out average cost of an AC (new thread)

[Tanlic]

I just installed my first Aircon 3 weeks ago. A 9000btu inverter in my bedroom. For health reasons it's best I maintain  temperature of 21c. My bedroom is 18sqm so 9000 btu is perfect. My bill is in a Thai name and she is currently unable to be contacted..However to work out my monthly cost what could be easier simply deduct last months bill for my new reading and it should give me a good idea of how much extra I can expect to pay per month....only one problem for the first time in 2years my electric bill has not turned up and it was due in my post box a week ago. Now I have no way of contacting them to complain because I don't have any old bills and I don't know my house address... luckily I can pay it next month when my next bill arrives...if it does arrive...only in Thailand😸

Since we don't really want to resurrect an 8-year-old thread, here's a new one 🙂 

 

Do you have access to your meter?

If so, it will have a reference number which you can take to your local MEA/PEA office and they should be able to tell you what you owe.

 

Your 9,000 BTU A/C will use about 900W when working hard, normally one assumes that a correctly sized unit will run at about 30%, so 300Wh (0.3kWh) per hour of use.

 

Of course, total energy consumption is very much dependent upon the weather, you may find your unit struggles to maintain 21C during the warmer months.

So you have no old Bill and don't know your address? Hope you still can remember your own name.

 

If you had any details you can see your Bills for the last six month regardless if they have arrived by mail.
