What Is a Home Energy Audit and Why Should You Get One?

Quick Answer

8 min read — here's the short version

The cost of a home energy audit can vary, but many utility companies in Pennsylvania, such as Duquesne Light and FirstEnergy, offer them at a reduced cost or even for free to eligible customers. It's best to check with your local utility provider for specific program details and pricing.

As a homeowner in Western Pennsylvania, you're likely accustomed to seasonal temperature swings and the energy costs that come with them. You might wonder if your home is running as efficiently as it could be. A professional home energy audit is one of the most effective ways to answer that question, providing a comprehensive roadmap to lower energy bills, increased comfort, and a safer home. This assessment goes beyond simple DIY checks, offering a detailed analysis of your property's energy performance and uncovering hidden issues that could be costing you money.

What Happens During a Professional Home Energy Audit?

A certified energy auditor conducts a thorough inspection of your home, which typically takes a few hours. The process is designed to be non-intrusive and highly informative. The auditor will examine your home from top to bottom to identify sources of energy loss and potential safety concerns.

Key steps in a home energy audit include:

  • A review of your past utility bills to understand your home's energy consumption patterns.
  • An exterior inspection to check for air leaks, insulation gaps, and other structural issues.
  • An interior, room-by-room inspection of insulation, windows, doors, and lighting.
  • A health and safety check, including testing for carbon monoxide and ensuring proper ventilation.
  • Specialized testing, such as a blower door test to measure air leakage and thermographic imaging to visualize heat loss.

Electrical System Insights from an Energy Audit

While an energy audit covers the entire home, it often reveals important information about your electrical system. Inefficient appliances, outdated lighting, and poor wiring can contribute significantly to energy waste. An audit can pinpoint these issues, helping you prioritize upgrades that offer the greatest return on investment. For instance, the report might highlight phantom loads—electronics that draw power even when turned off—or recommend upgrading to ENERGY STAR® certified appliances.

An energy audit can also uncover potential electrical safety hazards, such as overloaded circuits or outdated wiring. Addressing these issues not only improves efficiency but also protects your family and property.

Cost Savings and Available Programs in Pennsylvania

The primary motivation for many homeowners to get an energy audit is the potential for significant cost savings. By implementing the recommended improvements, homeowners can often reduce their energy bills by 5% to 30%. In Pennsylvania, several programs and incentives are available to help offset the cost of both the audit and the subsequent upgrades.

Pennsylvania homeowners can explore options such as:

  • Utility-sponsored programs, like those offered by Duquesne Light and Columbia Gas, which may provide free or discounted energy audits and rebates for efficiency upgrades.
  • State-level initiatives, such as those listed on the PA Department of Environmental Protection website, which offer financial assistance for energy-saving home improvements.
  • Federal tax credits for energy-efficient home improvements, which can further reduce the financial burden of making your home more sustainable.

From Audit to Action: The Role of a Licensed Electrician

Once you receive your home energy audit report, the next step is to take action. While some recommendations, like sealing air leaks, can be DIY projects, many electrical-related improvements require professional expertise. It is crucial to hire a licensed and insured electrician to perform any work on your home’s electrical system. This ensures that all upgrades are performed safely, are compliant with local codes, and will deliver the expected energy savings.
