Struggling with high utility bills? Wondering if your home is leaking heat in winter or absorbing too much warmth in summer? The good news is, you don’t need to be a professional to figure it out. With a do-it-yourself home assessment, you can uncover areas where energy is wasted and take steps to fix them.

A self-guided inspection helps identify inefficiencies that cost you money. Whether it’s drafty windows, poor insulation, or outdated appliances, small changes can lead to noticeable savings. While a detailed home assessment by an expert provides deeper insights, a personal walk-through can still highlight simple fixes that improve efficiency and comfort.

1. Understanding a Home Energy Checkup

A household efficiency check is like a health screening—it helps pinpoint issues that might be costing you money. The goal is to find weak spots and fix them before they drain your wallet.

Professional inspectors use advanced tools like blower door tests and thermal imaging, but even without them, a careful inspection can reveal problem areas. The key is to look for air leaks, outdated appliances, and inefficient heating or cooling systems that drive up expenses.

2. Essential Tools for a DIY Inspection

You don’t need a high-tech setup—just a few affordable tools can help identify problem areas

Infrared Thermometer – Helps detect temperature differences in walls and windows
Thermal Imaging Camera (optional) – Provides a visual representation of heat loss
Electricity Usage Monitor – Measures power consumption of appliances
Incense Stick or Candle – Reveals air movement around windows and doors
Smart Plug Power Meter – Tracks energy usage of electronics in real time
DIY Home Efficiency Checklist – Keeps track of your findings for future improvements

Having these items on hand makes your inspection more effective and ensures you catch problem areas that might otherwise go unnoticed

3. Step-by-Step Guide to Conducting an Inspection

Step 1: Locate and Seal Air Leaks

Drafts can waste up to 20 percent of heating and cooling costs Finding and sealing leaks is one of the quickest ways to improve efficiency

Where to check

Around windows and doors
Baseboards and floors
Electrical outlets and light fixtures
Attic access points and vents

How to test for drafts

Hold a candle or incense stick near suspect areas If the flame flickers or the smoke moves, you’ve found a gap

Fixing the issue

Apply weatherstripping around doors and windows
Use caulk or sealant for cracks along walls and baseboards

Step 2: Inspect Insulation Quality

Poor insulation results in wasted energy Even newer homes may not have enough insulation to prevent heat loss

Where to check

Attic – If insulation is below floor joists, consider adding more
Walls – Remove an outlet cover and probe inside No insulation That’s a red flag
Basements and crawlspaces – Check if insulation is installed under floors or along walls

How to upgrade insulation

Add fiberglass batts or spray foam in key areas
Consider upgrading to modern, high-efficiency materials

Step 3: Evaluate Heating and Cooling Systems

Your heating and cooling systems account for nearly half of your home’s energy use Even a well-maintained unit can waste power if not optimized

How to improve efficiency

Change filters regularly for better airflow
Clean air vents and ducts to remove dust buildup
Inspect for inconsistent temperatures in different rooms

If your unit is over 15 years old, consider upgrading to a high-efficiency system A more efficient model reduces waste and lowers long-term costs

Step 4: Check Lighting and Appliances

Old appliances and inefficient lighting quietly add up to significant expenses Making a few upgrades can immediately lower monthly costs

Where to make changes

Swap outdated bulbs for LEDs – they use 75 percent less electricity
Unplug devices when not in use to prevent standby power drain
Use smart power strips to cut electricity to idle electronics

If major appliances like refrigerators, dishwashers, or washing machines are older models, replacing them with energy-efficient versions can result in substantial savings over time

4. Quick Wins for Immediate Savings

Seal gaps around windows and doors
Lower water heater settings to 120°F (49°C)
Use a programmable thermostat for better temperature control
Run full loads in dishwashers and washing machines
Install blackout curtains to regulate indoor temperatures

For even greater long-term savings, consider investing in solar panels to reduce reliance on grid power

5. When to Bring in a Professional

A self-guided assessment is a great start, but some issues require expert analysis If you notice any of these signs, it might be time to call in a pro

Your bills remain high despite making changes
There are major insulation concerns
Your HVAC system isn’t performing efficiently
You want a detailed report on home energy usage

Professionals use specialized tools like blower doors and infrared cameras to detect hard-to-find inefficiencies If you’re interested in a deeper dive, check out this beginner’s guide to professional assessments
