10 Affordable DIY Energy-Saving Home Upgrades for 2025

Here are 10 actionable steps you can take today to start saving energy and money:

1. Seal Drafts Around Doors and Windows

Drafts are notorious energy wasters. Air leaks can account for 5% to 30% of energy use in a home. Identifying and sealing these leaks is one of the most effective DIY energy-saving home upgrades you can perform. Walk around your home on a windy day or use the “candle test” (carefully move a lit candle or incense stick near edges to see if the flame flickers) to find drafts around window frames, door frames, and even plumbing or electrical penetrations.

How-To: For windows and doors, use weatherstripping along the edges where the sash or door meets the frame. For gaps in frames or where frames meet walls, apply caulk. Ensure surfaces are clean and dry before applying. This simple step makes a significant difference.

• Estimated Cost: $10–$50 (for caulk and weatherstripping)
• Potential Savings: Moderate to High

Beginner Tip: Start with the areas you feel the most draft! The front door or leaky windows are often the easiest starting points for this energy-efficient upgrade.

2. Install Insulation Gaskets on Outlets and Switches

Think about how many electrical outlets and light switches you have on exterior walls. Each one is a small hole in your insulation barrier! Cold air can seep in during winter, and warm air during summer. Installing foam insulation gaskets behind the cover plates is a super simple and effective DIY energy-saving home upgrade.

How-To: Turn off the power to the outlet or switch at your breaker box (essential safety step!). Unscrew the cover plate. Place the pre-cut foam gasket over the outlet or switch box. Screw the cover plate back on. Repeat for all exterior wall outlets and switches.

• Estimated Cost: $5–$15 (for a pack of gaskets)
• Potential Savings: Low to Moderate

3. Upgrade to LED Lighting

Lighting accounts for a significant portion of home energy use. Replacing old incandescent bulbs with modern LED bulbs is one of the simplest and most rewarding energy-efficient upgrades. LEDs use up to 80% less energy and last much longer. This is a truly impactful yet easy change.

How-To: Simply unscrew the old bulb and screw in the new LED bulb! Be sure to match the bulb base size (e.g., E26 for standard sockets) and choose the desired brightness (lumens) and color temperature (Kelvin). Check our guide to eco-friendly products for more details.

• Estimated Cost: $20–$100+ (depending on how many bulbs you replace)
• Potential Savings: Moderate

4. Improve Window Efficiency with Film or Covers

While replacing windows is expensive, there are DIY ways to boost their efficiency. Window insulation film can create a seal that mimics double-paning, reducing heat transfer. Thick curtains or thermal drapes can also help retain heat in winter and block it in summer. This upgrade is particularly useful for older, less efficient windows.

How-To: For film, cut it to size, apply with water (often soapy water), and use a hairdryer to shrink it taut. For curtains, install sturdy curtain rods and hang thermal drapes, ensuring they cover the entire window area.

• Estimated Cost: $20–$50 (for film or basic thermal curtains)
• Potential Savings: Moderate

5. Lower Your Water Heater Temperature

Heating water is a major energy expense. Most water heaters are set to 140°F (60°C), but 120°F (49°C) is usually sufficient for typical household needs and can save a significant amount of energy. This is one of the easiest DIY energy-saving home upgrades with immediate results.

How-To: Locate the thermostat dial on your water heater. For electric heaters, this is usually behind a panel (turn off power first!). For gas heaters, it’s typically a dial on the unit. Adjust the setting down to 120°F. Be cautious with Legionella risks; consult CDC guidelines if concerned, but 120°F is generally safe.

• Estimated Cost: $0
• Potential Savings: Moderate to High

6. Maintain Your HVAC System (Especially Filters)

Your heating and cooling system is likely your home’s biggest energy consumer. While major maintenance requires a professional, regularly changing your air filter is a simple yet critical DIY energy-saving home upgrade. A dirty filter restricts airflow, making your system work harder and use more energy. It also reduces air quality.

How-To: Locate your air filter (usually near the air handler or furnace). Note the size printed on the filter frame. Purchase a replacement filter of the same size. Slide out the old, dirty filter and slide in the new one, ensuring the airflow arrow points correctly (toward the air handler). Change it every 1–3 months per the manufacturer’s recommendation.

• Estimated Cost: $10–$30 per filter
• Potential Savings: Moderate

7. Use Smart Power Strips

“Phantom energy” or “vampire power” is the energy consumed by electronics even when turned off but still plugged in. This can add up! Smart power strips detect when devices are off or in standby and cut power completely. This is a low-effort affordable green upgrade.

How-To: Plug devices used together (like your TV, DVD player, and game console) into a smart power strip. Plug your computer, monitor, and printer into another. The strip automatically cuts power to idle devices.

• Estimated Cost: $20–$40 per strip
• Potential Savings: Low to Moderate

8. Optimize Thermostat Settings (Manually or with a Programmable Thermostat)

Adjusting your thermostat based on whether you’re home or asleep is one of the most impactful home energy tips. Setting it back 7–10°F for 8 hours daily can save up to 10% on heating and cooling costs, per the U.S. Department of Energy.

How-To: Manually adjust your thermostat when leaving for work or going to bed. For easier savings, install a programmable or smart thermostat. Installation can be DIY with basic electrical knowledge; follow the manufacturer’s instructions or consult an electrician if unsure. Program setbacks or let a smart thermostat learn your habits.

• Estimated Cost: $0 (manual) – $50–$200+ (programmable/smart thermostat)
• Potential Savings: High

9. Optimize Appliance Usage

Sometimes, saving energy is less about hardware and more about habits. How you use existing appliances can significantly impact consumption. This is a free and easy affordable green upgrade.

How-To: Run dishwashers and washing machines only when full. Use cold water for laundry when possible. Clean the lint filter in your dryer after every use to improve efficiency. Unplug chargers when not in use. Defrost your freezer regularly if not frost-free. Use smaller appliances like microwaves for small meals instead of a large oven.

• Estimated Cost: $0
• Potential Savings: Moderate

10. Use Landscaping Strategically

Your garden can help save energy! Strategic landscaping provides shade in summer and acts as a windbreak in winter. Deciduous trees on the south or west side shade your home from hot summer sun after leafing out, then allow warming sunlight through in winter. Evergreen trees or shrubs on the north side block cold winter winds.

How-To: Plan landscaping with energy efficiency in mind. Consider tree types, mature height, and placement relative to your home and prevailing winds. Plant shrubs or vines near walls to create an insulating air buffer. This is a longer-term eco-friendly upgrade with lasting benefits.

• Estimated Cost: $50–$500+ (depending on plants purchased)
• Potential Savings: Moderate
