DIY vs. Professional Home Energy Audits: Which Is Better?

When it comes to improving the energy efficiency of your home, one of the first steps is to conduct an energy audit. An energy audit helps identify areas where your home may be losing energy and provides recommendations for improvements. While professional home energy audits have been the traditional choice, many homeowners are now considering the option of conducting a DIY energy audit. In this article, we will explore the pros and cons of both DIY and professional home energy audits to help you determine which option is better suited for your needs.

1. Cost

One of the primary factors that homeowners consider when deciding between a DIY and professional home energy audit is the cost. DIY energy audits are generally more affordable as they do not involve hiring a professional auditor. Instead, you can use online resources and tools to conduct the audit yourself. On the other hand, professional home energy audits can be more expensive, as you will need to pay for the services of a certified energy auditor.

However, it is important to consider the potential long-term savings that can result from a professional energy audit. A professional auditor has the expertise to identify energy-saving opportunities that may not be apparent to an untrained eye. By investing in a professional audit, you may be able to make more significant energy efficiency improvements, leading to greater savings on your energy bills over time.

2. Accuracy and Expertise

When it comes to accuracy and expertise, professional home energy audits have the upper hand. Certified energy auditors undergo extensive training and have in-depth knowledge of building science and energy efficiency. They are equipped with specialized tools and equipment to measure energy consumption, detect air leaks, and assess insulation levels.

On the other hand, DIY energy audits rely on the homeowner’s knowledge and understanding of energy efficiency. While there are online resources and guides available, conducting a thorough and accurate audit can be challenging without the proper training and equipment. Without the expertise of a professional, there is a higher chance of overlooking potential energy-saving opportunities or misinterpreting the results of the audit.

However, it is worth noting that a DIY energy audit can still provide valuable insights and identify some energy-saving measures. It can be a good starting point for homeowners who are looking to make initial improvements before considering a professional audit.

3. Thoroughness

Professional home energy audits are typically more thorough compared to DIY audits. Certified energy auditors follow a standardized process that involves a comprehensive assessment of your home’s energy performance. They conduct a detailed inspection of various components, including insulation, HVAC systems, windows, doors, and appliances.

During a professional audit, advanced tools such as thermal imaging cameras and blower doors are used to detect air leaks and assess the overall energy efficiency of the home. These tools provide accurate measurements and help identify areas of improvement that may not be visible to the naked eye.

On the other hand, DIY energy audits may not be as thorough due to the limitations of available tools and resources. Homeowners may not have access to specialized equipment, making it difficult to detect hidden air leaks or assess insulation levels accurately. However, with careful attention to detail and following comprehensive guides, homeowners can still perform a reasonably thorough audit.

4. Time and Effort

Another factor to consider when deciding between a DIY and professional home energy audit is the time and effort involved. DIY energy audits require homeowners to invest their time in researching and understanding energy efficiency concepts, as well as performing the audit itself.

While DIY audits can be time-consuming, they offer the flexibility of conducting the audit at your own pace. You can choose to focus on specific areas of concern or prioritize energy-saving measures based on your preferences and budget.

On the other hand, professional home energy audits are typically more efficient in terms of time and effort. Certified auditors have the knowledge and experience to quickly identify energy-saving opportunities and provide recommendations tailored to your home’s specific needs. They can also help prioritize improvements based on their expertise and industry standards.

5. Recommendations and Follow-up

One of the key benefits of a professional home energy audit is the detailed recommendations and follow-up support provided by the auditor. After conducting the audit, a certified energy auditor will provide you with a comprehensive report that outlines the findings, identifies areas of improvement, and suggests energy-saving measures.

These recommendations are often prioritized based on their potential impact and cost-effectiveness. Additionally, a professional auditor can provide guidance on available incentives, rebates, and financing options for implementing the recommended improvements.

DIY energy audits may not offer the same level of detailed recommendations and follow-up support. While online resources and guides can provide general suggestions, they may not be tailored to your specific home and energy needs. However, homeowners can still benefit from researching energy-saving measures and seeking advice from professionals or local energy efficiency programs.


When it comes to DIY vs. professional home energy audits, there are several factors to consider. While DIY audits may be more cost-effective and offer flexibility, professional audits provide greater accuracy, thoroughness, and detailed recommendations. Ultimately, the choice between the two depends on your budget, time availability, and the level of expertise you require.

If you are confident in your ability to conduct a thorough audit and have the time to invest in research and implementation, a DIY energy audit can be a good starting point. However, if you want a comprehensive assessment of your home’s energy performance and access to expert recommendations, a professional home energy audit is the recommended choice.

Regardless of the approach you choose, the important thing is to take action towards improving the energy efficiency of your home. By identifying and addressing energy inefficiencies, you can not only reduce your carbon footprint but also enjoy long-term savings on your energy bills.
