Every month, the utility bill rolls in, and you wonder — where is all that energy going? The good news is that you don’t need to be a professional energy auditor to find and fix your home’s biggest energy leaks. A DIY energy audit can help you identify drafts, insulation gaps and inefficient appliances that could be costing you money. With just a few simple steps, you can make your home more energy-efficient, save money and even make it more comfortable.
STEP 1: Find the Drafts
Drafts are one of the most common culprits behind energy waste. According to the U.S. Department of Energy (DOE), air leaks can account for up to 30% of a home’s heating and cooling losses.
Here’s an easy way to find them:
On a windy day, walk around your home with a lit incense stick or a small candle.
Hold it near windows, doors and vents — if the smoke flickers or the flame moves, you’ve found a draft.
Common problem areas include old window frames, under doors and around electrical outlets.
Fix it: Use weatherstripping, caulk or door sweeps to seal those gaps and keep the warm (or cool) air inside where it belongs. (Source: DOE)
STEP 2: Check Your Insulation
Poor insulation is a sneaky energy thief. If your home isn’t properly insulated, you could be losing heat in the winter and cool air in the summer. Per the Environmental Protection Agency (EPA), proper insulation can reduce heating and cooling costs by an average of 15%.
Head up to your attic and check if the insulation is evenly spread. If you can see the joists, you may need more insulation.
Touch your walls on a cold day — if they feel chilly, your insulation may not be up to par.
Inspect exterior walls and basement areas for any visible gaps.
Fix it: Add insulation where needed, using fiberglass batts, spray foam or blown-in insulation. (Source: EPA)
STEP 3: Evaluate Your Appliances and Lighting
Outdated or inefficient appliances can drain energy without you even realizing it. According to ENERGY STAR, appliances that are over 15 years old can use up to 50% more energy than newer, certified models.
Check your HVAC system’s age — if it’s over 15 years old, it might be time for an upgrade.
Look at your water heater settings; 120 F is usually sufficient for most households.
Swap out incandescent bulbs for energy-efficient LED ones.
Fix it: Consider replacing old appliances with ENERGY STAR-rated models and use smart power strips to cut down on phantom energy use. (Source: ENERGY STAR)
STEP 4: Inspect Windows and Doors
Even with proper insulation, old windows and doors can let energy slip away. The DOE states that heat gain and loss through windows are responsible for 25-30% of residential energy use.
Stand near windows and doors — if you feel cold air seeping through, they might be poorly sealed.
Look for condensation between windowpanes, which can indicate failing seals.
Fix it: Apply window film, use insulated curtains or consider upgrading to double-pane or energy-efficient windows. (Source: DOE)
STEP 5: Assess Your Thermostat and Habits
Your thermostat settings and daily habits play a big role in energy use. The DOE recommends setting your thermostat to 68 F in winter and 78 F in summer when you’re home to maximize efficiency.
Set your thermostat to recommended temperatures to save energy without sacrificing comfort.
Use a programmable or smart thermostat to optimize heating and cooling when you’re away.
Fix it: Small adjustments — like wearing an extra layer in winter or using fans in summer — can add up to big savings. (Source: DOE)
Small Changes, Big Savings
Performing a DIY energy audit doesn’t take long, but the benefits last for years. According to the DOE, sealing drafts, improving insulation, upgrading appliances and adjusting your thermostat can result in up to 20% savings on your energy bill. By making these small but impactful changes, you’ll not only lower your energy costs but also create a cozier, more eco-friendly home. So, grab that incense stick and start your energy-saving journey today!
