Are you tired of high energy bills and unsure how to make your home more efficient? A home energy audit could be the answer. This detailed assessment pinpoints where your home is wasting energy and offers practical steps to reduce costs, improve comfort, and lower your environmental impact. It also serves as a starting point for switching to solar energy, making your home more prepared for long-term savings.
Hidden draughts, aging appliances, and thin insulation often push energy bills higher than they need to be. A home energy audit shines a light on those weak spots, showing where heat slips out, where electricity is wasted, and which upgrades will give the biggest return. By fixing the worst offenders first, you cut running costs, boost comfort, and lay the groundwork for a smaller, cheaper solar system when you decide to tap the sun.
Understanding Home Energy Audits
What is a Home Energy Audit?
A home energy audit, also called a home energy assessment, is a thorough evaluation of how your home uses energy and where it may be wasting it. It highlights areas for improvement that can lower your utility bills and make your home more comfortable and environmentally friendly.
Carried out by trained professionals, a comprehensive audit examines your home’s structure (walls, roof, windows, doors), heating and cooling systems, appliances, and lighting. Auditors use tools like blower doors to detect air leaks, infrared cameras to identify heat loss, and software to model your home’s overall performance. In short, an energy audit is a roadmap to making your home more efficient.
Benefits of a Home Energy Audit
A home energy audit brings several key benefits:
- Lower energy bills: Fixing air leaks and adding insulation can reduce heating and cooling costs by up to 20%, according to the U.S. Department of Energy.
- Improved comfort: Your home will feel more stable in temperature with fewer drafts.
- Better safety: Audits can uncover hidden issues like mold or faulty appliances.
- Access to incentives: Many rebates and tax credits require an audit before upgrades.
- Smaller carbon footprint: Using less energy means less environmental impact.
When Should You Get a Home Energy Audit?
If your utility bills seem unusually high or certain rooms in your home feel drafty or uneven in temperature, your home may be wasting energy. Homes built several decades ago or fitted with outdated appliances often lack the insulation or efficiency found in newer builds. These are clear signals that an audit could help.
Some of the common signs include:
- Rising monthly energy costs
- Noticeable drafts or cold and hot spots
- Outdated HVAC systems or appliances
- Lack of recent energy upgrades
Getting ahead of these issues can help prevent larger costs down the road and improve your overall comfort at home.
Ideal Times for an Audit
It’s best to schedule a home energy audit before making major changes to your home. If you’re thinking about installing solar panels, an audit helps reduce the size and cost of the system by improving your home’s energy use first. Buyers of older homes can also benefit by identifying problems early.
Here are a few good times to consider an audit:
- Before installing solar panels
- After buying a home
- Every 5 to 10 years as part of routine home maintenance
Types of Home Energy Audits
DIY Home Energy Audits
Some energy inefficiencies can be spotted through simple at-home checks. Using online tools or checklists, you can walk through your home and identify visible problem areas.
Common issues include:
- Gaps around doors and windows
- Poor insulation in the attic
- Outdated, inefficient lighting
These checks are a good starting point for raising awareness, but they can’t replace a full professional assessment. DIY audits don’t uncover hidden problems or provide precise energy modelling.
Professional Home Energy Audits
For a more accurate view of your home’s energy use, professional audits are the better choice. They come in two main formats. Virtual audits rely on questionnaires and your utility bills. In-person audits include diagnostic tools and a full home inspection.
Professional audits may cost anywhere from nothing (through select utility companies) up to $1,000. In return, you receive a detailed report with savings estimates and upgrade recommendations tailored to your home.
Preparing for Your Home Energy Audit
What to Gather
Getting ready for a home energy audit doesn’t require much, but providing the right details will help the auditor give better recommendations.
Prepare the following:
- Utility bills from the past year
- Notes on drafty or uncomfortable rooms
- Information on insulation, appliances, and HVAC systems
- An overview of your daily energy habits
This background gives the auditor a clearer picture of how your home functions day to day.
What to Expect During the Audit
The auditor will inspect each room and examine insulation, windows, appliances, and ductwork. Blower doors and infrared cameras may be used to measure heat loss and air leaks.
In-person audits typically take one to two hours. Virtual audits are shorter, lasting about 30 to 60 minutes depending on the size of your home.
The Audit Process and Recommendations
What the Auditor Will Do
Expect the audit to focus on areas with the highest potential for energy loss. These include:
- Attic and wall insulation
- Seals around windows and doors
- Ductwork connected to your HVAC system
- Appliance efficiency and lighting choices
Each item is assessed for performance and prioritised based on improvement potential.
What You’ll Receive
Once the audit is complete, you’ll get a report that outlines key findings. It typically includes:
- Areas where energy is being lost
- Recommended upgrades
- Estimated costs and expected annual savings
- Available tax credits and rebates
Implementing Energy Efficiency Upgrades
Common Recommendations
Most audits recommend starting with energy efficiency upgrades after audit, such as air sealing and insulation, which address major energy losses. Upgrading to an ENERGY STAR-rated HVAC system can save up to 15% on heating and cooling costs. Replacing old appliances with efficient models further reduces consumption. These upgrades are often eligible for rebates, enhancing their cost-effectiveness.
Advanced Upgrades
For greater savings, consider advanced upgrades such as ventilation systems, smart thermostats, or renewable energy options. Installing solar panels can reduce electricity bills by 50 percent or more when the home is already running efficiently. These improvements lower energy use, increase property value, and support long-term sustainability.
Cost and Incentives for Home Energy Audits
How Much Does an Audit Cost?
The question of how much a home energy audit cost depends on the type. Free home energy audits are offered by utilities like Duke Energy, while comprehensive audits range from $300 to $1,000. For example, SRP offers audits for $49 or free for income-qualified customers. The investment often pays off through energy savings and available incentives.
Available Rebates and Tax Credits
Numerous incentives make audits and upgrades affordable. The federal home energy audit tax credit offers up to $3,200 annually for efficiency improvements, per ENERGY STAR. Utilities like Duke Energy provide rebates up to $3,050 for upgrades like insulation or HVAC replacement. Check with your local utility or state programs for additional savings opportunities.
