To reduce utility bills, the first step is to find out where you are wasting energy.
To do this, you need a residential energy inspection—which should be done by a certified energy inspector who has no financial
interest in the improvements recommended.
The energy inspector will examine, measure, and evaluate the factors that affect energy use in your home, e.g., size of the home, efficiency of appliances,
insulation, draftiness of rooms, and efficiency of heating and cooling systems (HVAC).
