It's a problem all over the world, even here in Phuket, Thailand our electric has gone up 300%, from next month the temperature will rise so the A/C will get hammered, here guest have the place like a fridge,
They just dont get it, leaving the doors and windows open does more damage,
I have not much choice but to increase my rates and I added a cleaning fee for the first time, everything you need to run an airbnb has also gone up,
These day there are allsorts of smart gadgets you can buy to control your heating, contact a local company for advise.
