What is a home energy audit? A home energy audit is a comprehensive examination of a home’s energy use and energy waste. In the United States, audits generally address insulation, air sealing, heating and cooling systems, appliances, etc.
A typical audit consists of a walk-through inspection, blower door test and infrared scan. Those results indicate where simple fixes, like sealing gaps or adding insulation, can make the biggest difference.
Both immediate and long-term, these changes will lower monthly home operating costs, increase comfort, and protect the environment. The following sections explain what you can expect and how to maximize the benefits of an audit.
What Is a Home Energy Audit?
A home energy audit is an in-depth evaluation of a home’s energy use. It reveals where your energy is leaking out, identifies how you can save the most, and provides easy to understand recommendations for improvement. The process combines a detailed, hands-on inspection with advanced diagnostic tools, but the key is a knowledgeable, trained energy auditor.
The typical audit takes three to four hours. These audits don’t have to be in-depth examinations; they can be simple walkthroughs, if that’s all the homeowner requires.
1. Uncovering Hidden Energy Waste
Energy audits go beyond the surface to uncover how homes waste energy. They test heating, cooling, and appliances for waste. Old insulation and air leaks in attics and walls can increase your energy bills.
This can be particularly important in areas that experience extreme summer heat or winter conditions. Auditors test the efficiency of the systems and appliances in the home, and then compile everything into a detailed report. This analysis pinpoints where homes typically waste the most energy and which improvements pay off the most.
2. What Auditors Inspect Inside
From the first step through the door, each major system is thoroughly examined. Major HVAC units, including furnaces and ACs, are inspected for any signs of future issues. Insulation levels in attics, walls and floors are checked to determine whether more insulation should be added.
Auditors additionally examine lighting and outlets to identify easy energy-saving opportunities. They also examine how the home’s structure impacts how energy moves through the house.
3. Auditor Tools: A Closer Look
Smart tools help auditors uncover hidden waste. Blower door tests are used to identify air leaks. Thermographic cameras can identify cold or hot air leaks in your home.
Energy monitors are a great tool to track the amount of electricity appliances consume. Moisture meters test for moisture that can damage efficiency.
4. Health and Safety Checks Included
Health and safety solutions are included in every audit. During an energy audit, carbon monoxide is detected, air flow is tested, and hazardous electrical wiring can be identified.
Air quality and safety of systems should be the priority.
5. Your Personalized Energy Roadmap
The audit concludes with a personalized plan. It prioritizes specific upgrades, establishes clear energy goals, and provides a timeline for implementing improvements.
This personalized roadmap is designed to put more money back in the pockets of homeowners, while reducing energy usage.
Big Wins from an Audit
A home energy audit will provide you with a complete picture of where your house is wasting energy, and which improvements provide the best return on investment. By identifying leaks, inefficient appliances, or drafty windows, audits empower homeowners to understand what is working and what needs to be repaired or replaced.
These wins are more than just modestly lower bills—they improve comfort, boost home value, and help save the planet.
Lower Bills, More Savings
Homeowners who take audit recommendations typically save 15-30% of their energy use. That’s a huge reduction in bills. Replacing incandescent bulbs with LEDs, caulking around windows, and using a programmable thermostat are all 5-15% savings.
In colder climates, increased insulation and more efficient heating systems can reduce heating bills by 30%. The more time passes, the more the savings accumulate, but measuring bills before and after an upgrade helps illustrate the tangible difference.
You can achieve 20-30% savings on energy bills in the first year alone. For all of these reasons, these changes represent a wise investment!
A More Comfortable Home
Energy audits aren’t just about saving money—they increase comfort. You can seal gaps to prevent drafts and ensure heat or cool air stays in your home—saving you money and energy.
Insulation helps maintain a consistent temperature inside, so bedrooms feel warm and toasty in the winter and pleasantly cool during summer months. With improved air circulation and reduced temperature extremes, the home is now more comfortable overall.
Improvements to heating and cooling help ensure cleaner air and a healthier home 12 months a year.
Higher Home Resale Value
Buyers pay a premium for homes with lower expected energy bills. We know energy-efficient features, such as new insulation or smart thermostats, increase property value.
Marketing such cost-effective upgrades on tours will help these homes stand out from the competition. As homebuyers increasingly seek out greener, cheaper-to-run homes, these changes are marketing assets.
Greener Living, Smaller Footprint
Energy audits help direct homeowners to the biggest wastes and the best strategies to save money and reduce their carbon footprint. The less power we use, the more emissions we can avoid.
Installing solar panels or enrolling in your locality’s green programs have a much larger impact. Each of these moves is benefitting the planet, while helping to inspire transformative change in the external community.
DIY vs. Professional Audits
Which option is right for you will vary based on your unique circumstances. Consider how much time and money you’re willing to spend! Either choice will help you identify the areas in your home contributing to energy loss. The specifics, tools used, and results can vary greatly.
Professional Audits: The Full Picture
Professional audits—especially those offered by specialists with a home performance background—provide a full picture of your home’s energy use. Using advanced diagnostic tools such as blower doors and thermographic cameras, certified auditors can identify air leaks and areas with inadequate insulation.
The whole process usually only takes two to three hours. Costs vary from $100 to $1,650, based on the size of your home and where you live. The audits involve an examination of previous utility bills. They go beyond energy alone to include health and safety checks, and inspections of wiring and combustion systems.
Professional reports are thorough, explaining in detail where you are losing energy and which measures will be the biggest bang-for-your-buck. This insider knowledge can result in far greater savings, particularly if your home has more obscure or intricate problems. As an example, only trained professionals should ever attempt to find leaks in concealed walls. They do a great job testing for air flow in attics.
DIY Audits: A Good Start
DIY audits are a cost-effective way to identify basic problems. You can look for drafts by running your hand along windows and doors. By unplugging appliances, you’ll learn which ones are energy hogs.
Helpful online guides and checklists—often put together by local utilities—can simplify the process and get you started. You can often identify damaged weatherstripping or gaps in insulation in your own home. However, how a DIY check pales in comparison to a professional audit is significant.
Most people don’t have access to the specialized tools or the expertise to identify more subtle defects.
Making the Right Choice for You
If you’re a little handy and looking to save costs, then a DIY audit is an excellent first move. For homes that have more extensive issues or if you want a more comprehensive review, a professional audit is a worthwhile investment.
Communicating with potential local auditors can provide you with unique insight into what services they provide and what services you truly need.
Choose Your Energy Auditor Wisely
Your choice of energy auditor will greatly determine the level of value you receive from a home energy audit. A qualified auditor is the promise of better results, clearer savings plans and peace of mind. If you’re looking to hire one, you need more than a Google search or the cheapest bid.
Comparing at least two or three providers will ensure that you are getting the most bang for your buck. It also makes sure your home gets the most complete inspection possible!
Key Auditor Certifications (US Focus)
Choose auditors with credentials from reputable organizations, such as the Building Performance Institute (BPI) or RESNET. These indicate the auditor has completed rigorous examinations and continues to stay informed on industry standards.
Ongoing training is crucial, because building codes and methods of achieving efficiency are rapidly advancing. Since both BPI and RESNET are deeply rooted in energy efficiency and home performance, the quality of their credentials has to count for something.
Always request proof of these certifications. It’s perfectly okay to ask if the auditor is working under a certified supervisor.
Questions to Ask Potential Auditors
Find out whether they have experience in your type of project and any similar past projects. Ask what measures they use—blowers to test for leaks, thermal cameras for hidden drafts, etc.
Inquire about the duration of the audit (typically two to three hours) and when you can expect the report to be issued. Check whether they’re familiar with local efficiency programs and whether they require your energy bills in advance.
A qualified, competent auditor should be able to address each of these questions with specific information.
Tap Into Local US Incentives
Learn more about US-centric rebates and tax credits available in your area. Federal tax incentives for home energy audits maximum out at $150 per audit under specific regulations.
Many local utilities provide free or low-cost energy audits. Visit their websites or have your auditor guide you through the application process.
Done correctly, these programs will make your upfront costs much lower, while increasing your total savings.
Post-Audit: Your Action Plan
After a home energy audit, what most people get is a laundry list of recommended upgrades. These upgrades range from minor retrofits to major capital endeavors. This is where an action plan comes in handy. By taking a step-by-step approach, homeowners can take tangible steps today that reduce energy use and save money.
Prioritize Audit Recommendations
Begin with prioritizing the recommendations from your audit. Start by prioritizing the energy upgrades that save the most energy for the lowest cost. Sealing drafts and putting in insulation usually lead this list, because they’re inexpensive and pay off immediately.
Replacing them with energy-efficient windows and doors will be more expensive initially. However, they create more savings on your heating and cooling bills over time. Quick wins, such as shutting off lights or unplugging appliances, yield immediate savings.
After some time, take a look and update your plan to make sure it’s meeting your evolving needs and objectives.
Calculate Your Payback Time
In order to determine if an upgrade is worth it, calculate payback time. Use this formula: Payback Time = Upfront Cost ÷ Yearly Savings. For instance, if a smart thermostat costs $150 and saves you $50 a year, your payback is three years.
This process allows you to prioritize improvements that return their investment more quickly. It casts a new light on the true value of larger projects, such as solar installations!
Monitor Your Energy Use
Once you’ve implemented changes, use energy tracking tools to monitor how much you’re saving. Real-time usage is available on most smart meters and through apps today.
Review your bills monthly to see patterns or radical increases. Create alerts for unusual increases. Monitor performance and continue to search for opportunities to achieve even greater savings.
This both keeps savings in line and allows for new issues to be identified quickly.
Energy Audit Myths & Future
Energy audits are known for having a very negative connotation as being expensive, overly invasive or only necessary in homes that are older. As standards evolve and smart technology continues to develop, the truth is a much more useful and applicable for today’s homebuyers.
