Quick Wins (do this week)
- Swapped 8 incandescent bulbs for LEDs (save ~$70/yr)
- Added weatherstripping to two exterior doors (save ~$35/yr)
- Set water heater to 120°F (save ~$25/yr)
- Plugged TV and console into a smart power strip (save ~$10/yr)
Medium Efforts (this month)
- Installed a programmable thermostat (save ~$80/yr)
- Added foam gaskets behind outlet covers on exterior walls (save ~$15/yr)
- Cleaned refrigerator coils (save ~$10/yr)
Bigger Projects (talk to landlord)
- Attic insulation upgrade (save ~$150/yr)
- Window replacement in north bedroom (save ~$60/yr)

Common Questions
How long does a room take to audit?
Most rooms take 5 to 10 minutes. The kitchen and basement tend to take a little longer because there are more items to check. You can save your progress and come back later.
What if I rent and cannot change things like insulation or windows?
The checklist marks items you can fix yourself (like weatherstripping or LED bulbs) and items that need a landlord (like wall insulation or window replacement). The Landlord Request builder pulls only the items that need property-owner approval so you can send a clear, polite request.
Do smart power strips really save money?
Yes, but only on entertainment centers and office setups where several devices sit on one strip. A smart power strip can cut 5 to 10 dollars a year per setup by stopping phantom loads. It is not a magic fix, but it is one of the cheapest upgrades you can make.
Should I set my thermostat back when I am home and awake?
Only if you are comfortable with it. The biggest savings come from setting it back when you are asleep or away for more than a few hours. A programmable or smart thermostat can handle this automatically and typically pays for itself in one heating or cooling season.
How often should I re-do this audit?
Once per season is a good rhythm. Weather changes reveal different problems. Drafts show up in winter, AC issues in summer, and appliance habits shift with your schedule. Each time you come back, uncheck items you have already fixed to see your progress.
Are the savings numbers accurate for my area?
The estimates are based on U.S. national averages from the Department of Energy and Energy Star. Your actual savings depend on your climate zone, utility rates, home size, and current equipment. Use the numbers to compare fixes, not as a guarantee.

Mistakes People Make During an Audit
Skipping the easy stuff
People jump to big projects like new windows and ignore the $5 fixes. A tube of caulk and a door sweep can save as much as some expensive upgrades.
Only auditing once
Energy waste changes with the seasons. A home that is tight in summer might have winter drafts you never noticed. Come back each season.
Ignoring phantom loads
Devices that are "off" still draw power if they are plugged in. Entertainment centers, chargers, and office equipment add up. A smart power strip is the simplest fix.
Forgetting the water heater
Many water heaters ship set to 140°F. Dropping it to 120°F saves energy and reduces scald risk. It takes two minutes and costs nothing.
