Thanks for your good recommendations and advice, everyone. I don't think my 2 small air purifiers cost that much in electricity. I'm coordinating with MEA to do another meter check/investigation of my high bill. S

I live in a 85sq meter, newish (2 year old) 2BR/2BA condo in Ekkamai, Bangkok. My summertime MEA electric bills are usually 3500--4500baht per month, with normal usage. I do work from home and keep the A/C temperature in my 3 wall units at 28 constantly during day/22 at night (in just one bedroom unit). I was away from my condo the ENTIRE month of July and turned all 3 AC units off. It was empty with no tenants and no one coming in at all. I only had the refrigerator and 2 small air purifiers running. No other electrical usage that I can think of. The July bill for the "empty period) was 2500baht and June was 3700baht. Last year's July bill when I was here in BKK was closer to 4000 baht. Why is my July bill only 33% less than June, when no AC was running at all? The Juristic checked the meter and said it was fine. Can MEA do anything to verify this? Any thoughts? Thanks. S
