Here in the Okanagan it's not unusual to be in the mid to high 30's outside for a couple of weeks straight at the height of summer. The central air in my older home hasn't worked since I moved in, yet I'm able to stay reasonably comfortable using a portable air conditioner & by opening all the windows overnight. I don't require a chiller for my fish tank. Due to the clear skies during these hot spells, it cools off substantially overnight, similar to a desert where it can drop to near freezing. Some folks simply seal up their homes 24/7 & run central air all summer. Don't think I could afford the hydro bill & if BC Hydro has their way, prices will rise substantially over the next few years. Time to invest in some solar panels & get the wind generator on the roof.
