Experience, training or licensing may be needed
All homeowners are always on the lookout for ways to save on their utility bills. You can come to their aid by providing them with an audit of their house and giving them a breakdown of how they could accomplish real savings in heating, cooling and electrical use. You can go one step further and do the implementation and installation of some of your suggestions in their home yourself. Do a complete appliance audit, with efficiency ratings and calculations based on the age of the appliance. And don’t forget the water heater!
