My new office air conditioning can get really cold. So much so I have left a permanent emergency layer there just in case. There is nothing worst than feeling like doing jumping jacks in the middle of summer because you are freezing.
At home we hover at the 74 - 75 degree F range. Not enough to make one freeze but enough to take the humidity out of the air. It is not on overnight. The house has done really well this season in light of our high high temperatures.
They are calling for 49 C humidex today and there is talk records may be broken.
Our city has asked people not to water lawns due to lowered water levels from lack of rain the past month. Our grass is showing dry patches now. They say it is just going dormant.
We have made an extra effort to close blinds during the day to help keep heat out. Our hydro and water bill came out to $108 last month. Not bad for us especially when actual usage is barely half of it.
Being on well and septic at the cottage has advantages here. Not having to pay for usage or the fees that cost well more. Makes for reasonable monthly running expenses.
