How to Conduct a Home Energy Audit and Save Money

What is a Home Energy Audit?

A home energy audit is a thorough assessment of your home’s energy use. It identifies areas where energy is being wasted and provides recommendations for improvements. The goal is to make your home more energy-efficient, which can lower your utility bills and reduce your carbon footprint.

Benefits of a Home Energy Audit

• Lower Energy Bills: Identify and fix energy-wasting issues to save money on utilities.

• Increased Comfort: Improve insulation and sealing to maintain consistent temperatures.

• Environmental Impact: Reduce your home’s energy consumption and greenhouse gas emissions.

• Home Value: Energy-efficient homes are more attractive to buyers and may have a higher resale value.

How to Conduct a DIY Home Energy Audit

While hiring a professional auditor is the most comprehensive option, you can perform a basic audit yourself. Here’s how:

1. Gather Your Tools

Before starting, gather the following tools:

• A notepad and pen to record findings.

• A flashlight for inspecting dark areas.

• A candle or incense stick to detect air leaks.

• A thermometer to check for temperature inconsistencies.

• A smartphone or camera to document issues.

2. Analyze Your Energy Bills

Start by reviewing your energy bills to understand your usage patterns.

• Compare Bills: Look at bills from the past year to identify seasonal trends.

• Check Usage: Note any spikes in usage that could indicate inefficiencies.

3. Inspect for Air Leaks

Air leaks are a major source of energy loss. Check for drafts around:

• Windows and Doors: Feel for drafts or use a candle to detect air movement.

• Electrical Outlets and Switches: Remove covers and check for gaps.

• Attic Hatches and Basement Walls: Look for cracks or gaps where air can escape.

Fix It: Seal leaks with caulk, weatherstripping, or foam sealant.

4. Check Insulation

Inadequate insulation can lead to heat loss in winter and heat gain in summer.

• Attic: Measure the depth of insulation. The U.S. Department of Energy recommends at least 10-14 inches of insulation for most climates.

• Walls: Check for insulation by removing outlet covers and peeking inside.

• Floors: Inspect crawl spaces and basements for insulation.

Fix It: Add insulation where needed, focusing on the attic and walls.

5. Evaluate Heating and Cooling Systems

Your HVAC system is a major energy consumer. Inspect it for efficiency.

• Filters: Check and replace dirty filters regularly.

• Ducts: Look for leaks or disconnected sections in ductwork.

• Thermostat: Ensure it’s programmable and set to energy-saving temperatures.

Fix It: Schedule annual maintenance, seal duct leaks, and upgrade to a smart thermostat.

6. Assess Lighting

Lighting accounts for a significant portion of home energy use.

• Bulb Types: Replace incandescent bulbs with energy-efficient LEDs.

• Usage: Turn off lights when not in use and consider motion sensors or timers.

Fix It: Switch to LEDs and install energy-saving controls.

7. Examine Appliances

Older appliances can be energy hogs. Check the energy efficiency of:

• Refrigerators and Freezers: Ensure they’re set to the recommended temperatures.

• Washing Machines and Dryers: Use cold water for washing and clean dryer lint traps.

• Dishwashers: Run full loads and use energy-saving modes.

Fix It: Upgrade to ENERGY STAR-certified appliances.

8. Inspect Water Heating

Water heating is another major energy expense.

• Temperature: Set your water heater to 120°F (49°C).

• Insulation: Wrap the water heater and pipes with insulation.

• Leaks: Check for leaks in faucets and pipes.

Fix It: Insulate the water heater and fix leaks promptly.

When to Hire a Professional

While a DIY audit can identify many issues, a professional energy audit provides a more comprehensive assessment. Consider hiring a professional if:

• You want a detailed analysis using specialized tools like blower doors and thermal cameras.

• Your home has persistent comfort issues, such as uneven heating or cooling.

• You’re planning major renovations and want to prioritize energy-efficient upgrades.

Tips to Maximize Savings

After completing your audit, take action to improve your home’s energy efficiency:

• Seal and Insulate: Address air leaks and add insulation to reduce heating and cooling costs.

• Upgrade Appliances: Replace old appliances with energy-efficient models.

• Install Smart Thermostats: Optimize heating and cooling schedules.

• Switch to LEDs: Replace incandescent bulbs with energy-saving LEDs.

• Use Power Strips: Reduce phantom load by plugging devices into smart power strips.

Final Thoughts

Conducting a home energy audit is a simple yet powerful way to save money and improve your home’s efficiency. By identifying and addressing energy-wasting issues, you can lower your utility bills, increase comfort, and reduce your environmental impact. Whether you do it yourself or hire a professional, the insights gained from an energy audit will help you make smarter decisions about your home’s energy use.
