Why Every Homeowner Should Start with a DIY Energy Walk-Through

When homeowners think about making their house more energy efficient — or when they consider installing solar panels — the first step isn’t picking out appliances, it’s understanding how much energy the home wastes right now. That’s where a Do-It-Yourself (DIY) home energy assessment— essentially a simple DIY Energy Walk-Through comes in. As the U.S. Department of Energy (DOE) puts it: while a professional energy audit provides the most detailed results, a careful DIY inspection can still reveal many of the “easy wins.”
Doing this simple home walk-through doesn’t require expensive equipment — but it can help you spot leaks, insulation issues, inefficient systems, and other inefficiencies that drive up energy bills. For homeowners in Arizona’s heat (or winters elsewhere), that insight can lead to big savings, improved comfort, and smarter investments when upgrading or retrofitting your home.
What to Look For: A Simple DIY Energy-Check Checklist
Here are the key things you’ll want to inspect during your walk-through, based on DOE guidance:
• Air leaks & drafts
Walk along walls, baseboards, ceilings, and flooring edges.
Examine windows, doors, electrical outlets, plumbing & lighting fixtures.
Don’t forget less obvious spots like where different building materials meet (e.g. siding and foundation), or older fireplace dampers.
Sealing leaks and drafts can reduce energy waste by 10–20% per year — plus increase summer cooling and winter heating efficiency.
• Insulation
Check attics, ceilings, and crawl spaces. Ensure attic hatches are insulated and weather-stripped, ductwork is sealed, and chimneys or vent openings are properly closed and sealed with non-combustible sealant if needed.
In older homes especially, “standard insulation at the time of build” may no longer be sufficient given today’s energy costs.
• Heating, Cooling & HVAC systems
Inspect filters and replace regularly if you have a forced-air system (clean filters help your system run more efficiently).
If your system is older than ~15 years, it may be worth considering replacement — newer units are often significantly more energy-efficient.
Check ductwork for dust streaks or visible air leakage — sealed ducts make a real difference.
• Lighting, Appliances & Electronics
Replace inefficient bulbs with energy-saving options (e.g., LED) — since lighting alone can account for a meaningful fraction of electricity costs.
Unplug rarely used devices to avoid “phantom loads.”
Consider upgrading older appliances to more efficient models, or using smart home energy-management tools.
After the DIY Walk — What’s Next
Once you’ve completed your DIY energy-check and documented areas needing improvement, it’s often worth bringing in a professional energy auditor for a comprehensive assessment. A professional audit — often using tools like blower-door tests, infrared cameras, and combustion-safety inspections — creates a detailed roadmap of where your home is losing energy.
That roadmap can help you:
Prioritize upgrades and retrofit projects.
Estimate energy and cost savings.
Identify home-safety or air-quality risks.
If needed, qualify for rebates or financing aids for energy-efficient home improvements.
How SHILA Can Help
At Sustainable Home Improvement Loans of Arizona (SHILA), we believe every homeowner deserves the chance to save money, reduce energy waste, and make their home more comfortable.
