Set Your Air Conditioner to 82°Based on the overall efficiency of your home you can save 4-7% of your air conditioning cost per degree. For example, if you normally set your thermostat for 75°, you will save 28-49%. That can be sizeable savings on your next bill. You may consider upgrading your thermostat to a programmable model if you don’t have one. Many of the new smart thermostats will program themselves, and they will automatically go into an away mode when no one walks past it for some time. This can save you money on normal days when no one is home as well. https://www.lowes.com/pd/Nest-Stainless-Steel-Learning-Thermostat-with-Built-In-Wifi/999917946
Set Your Water Heater To Vacation ModeNatural gas, propane or an electric heat pump water heaters have a vacation setting right on the controls where you can see it easily. You simply set the control to vacation mode when you are ready to leave. This will cause your water heater to run far less while you are gone. If you have a gas tankless water heater, this is no concern because they only heat water as you need it.
