Do-It-Yourself Home Energy Assessment

A diligent self-assessment can help you pinpoint problem areas and prioritize your energy-efficiency upgrades. Learn more about how to perform a self-assessment below.

Check Your Energy Bill

Check Your Energy Bill

Familiarize yourself with the separate charges for your natural gas, electricity and water usage (if applicable) that appear on your monthly energy bill(s). Track how much you spend on average each month to gain a clearer understanding of your energy expenditures—and where you can start saving.

Look for Leaks

Look for Leaks

Check all the plumbing in your kitchen and bathroom(s). You’re looking for any water leaks, any loose or deteriorating seals, or pipes that might need to be replaced.

Check for Drafts

Check for Drafts

If you can see any sunlight between your doors and windows and their frames, or if you feel any air seeping through, your home isn’t properly sealed. In winter, when cold air enters and warm air escapes, the cost of keeping your home at a comfortable temperature rises. In summer, drafts can bring warm outside air into your home and increase your use of air conditioning. Places to check for drafts include windows, doors, lighting, plumbing fixtures, switches, and electrical outlets.

Take the Temperature

Take the Temperature

What’s your thermostat set to, and is it programmable? Setting thermostats lower in winter can help save a bundle on heating costs, while raising the setting in summer can lessen your use of air conditioning.
