Home Energy Audit Checklist: Lower Your Bills with Strategic Upgrades
Your energy bill is slowly creeping up every year. You’re paying more to stay warm in winter and cool in summer. Yet you have no idea where all that energy (and money) is going.
An energy audit reveals the answer. Professional energy audits identify exactly where your home is losing energy—and which upgrades deliver the best ROI.
At Peak Precision Contracting, we’ve helped hundreds of Pittsburgh and Canonsburg homeowners reduce energy bills by 15-25%. Here’s your complete guide to auditing and upgrading your home.
What is a Home Energy Audit?
An energy audit is a comprehensive assessment of how efficiently your home uses energy. A professional auditor identifies:
- Where energy is escaping (air leaks, poor insulation)
- Which systems are inefficient (HVAC, water heater, appliances)
- Which upgrades will save the most money
- Which upgrades qualify for tax credits/rebates
DIY Energy Audit Checklist
Do this before hiring a professional:
HVAC System:
- Thermostat programmable or smart?
- When was HVAC system installed? (>15 years old = inefficient)
- Any unusual heating/cooling patterns? (some rooms always cold/hot)
- Furnace filter clean? (restricts airflow if dirty)
Insulation:
- Attic insulation visible? (if you see joists, it’s inadequate)
- Basement rim joist insulated?
- Crawl space insulation present?
- Walls feel cold in winter near exterior?
Air Leaks:
- Drafts around windows/doors?
- Outlets on exterior walls cold to touch?
- Basement feels draftier than upstairs?
- Attic hatch weatherstripped?
Windows & Doors:
- Single-pane or double-pane windows?
- Any gaps or weatherstripping missing?
- Doors close properly and seal tightly?
Water Heating:
- Tankless or traditional water heater?
- How old is water heater? (>10 years = consider replacement)
- Pipes insulated?
Appliances:
- Energy Star rated?
- When purchased? (old = inefficient)
Lighting:
- LED or incandescent bulbs?
- Outside lights always on?
Professional Energy Audit ($200-$500)
A professional uses:
Blower Door Test: Measures air leakage by depressurizing your home. Shows exactly where drafts are.
Thermal Imaging: Infrared camera detects temperature differences, revealing insulation gaps and air leaks invisible to the eye.
HVAC Assessment: Checks system efficiency, ductwork leaks, and proper airflow.
Water Heater Inspection: Tests efficiency and recovery rate.
Appliance Evaluation: Checks age and efficiency ratings.
