If you’re a Maryland homeowner dealing with high utility bills, rooms that are too hot or cold, or signs of energy loss like condensation or drafts, an energy audit could be your first step toward a more efficient, comfortable, and cost-effective home.
In this guide, we’ll break down everything you need to know about energy audits in Maryland, including their benefits, what they cost, available rebates, and a step-by-step look at the process.
Why Now Is a Great Time for a Maryland Home Energy Audit
Over the past winter, homeowners across Maryland have taken to Facebook, Nextdoor, and community forums to voice frustration over soaring electric and gas bills in January and February. While some of these cost increases are due to rate hikes and colder-than-usual weather, another huge factor is what’s happening inside each home.
Older houses, split-levels, Cape Cods, and homes with rooms over garages often have unsealed attics, leaky ducts, poor insulation, and aging HVAC systems that are not energy efficient. That means your heating and cooling system works overtime—and your bills reflect it.
A professional home energy audit by a certified energy auditor can help you some of the issues that caused high bills this winter and prevent a repeat performance during the coming summer months, as well as next winter.
You’ll find out why your upstairs bedrooms are boiling, why your A/C runs constantly, and what simple upgrades can solve these problems long-term.
You’ll also get guidance on the many different rebates available for improvements, from federal to state to local.
What Is a Home Energy Audit?
An energy audit is like a home inspection, but with a laser focus on energy performance. It identifies where your home is losing energy and how you can improve comfort while reducing utility bills. A certified energy auditor assesses insulation, ventilation, HVAC systems, and areas of air leakage using tools like:
- Blower door testing to locate drafts
- Infrared imaging to find hot or cold spots
- Combustion safety testing for gas appliances
- Utility bill analysis to identify usage patterns
The result is a detailed report outlining where your energy dollars are going—and how to minimize energy costs.
How Much Does an Energy Audit Cost in Maryland?
Thanks to the Home Performance with ENERGY STAR® program, homeowners in Maryland pay only $100 for a complete home energy audit. EmPOWER Maryland funding (which you are already paying into via your utility bills) covers the rest of the audit.
What Are the Benefits of an Energy Audit?
Beyond identifying problem areas, an energy audit unlocks immediate and long-term benefits:
- Lower energy bills
- Greater comfort year-round
- Reduced HVAC strain and longer system life
- Healthier indoor air quality
- Access to rebates and federal tax credits
- Peace of mind before the next extreme season

What Happens During an Energy Audit?
Here’s what to expect from a professional audit:
- Initial Consultation: The auditors set expectations and learn about your specific comfort or efficiency concerns.
- Attic and Insulation Inspection: They evaluate insulation levels and check for air leaks.
- Ventilation Review: They assess attic airflow to prevent moisture buildup and heat gain.
- Whole-Home Measurements: Dimensions and conditioned space are recorded for modeling.
- Blower Door Test: This depressurizes your home to expose air leaks.
- Infrared Imaging: Thermal cameras identify hidden insulation gaps and leaks.
- Combustion Safety Testing: Gas appliances are checked for safe operation.
- Utility Bill Analysis: Your bills are compared to similar homes.
- Custom Energy Audit Report: You get a full breakdown of issues, solutions, estimated savings, and eligible rebates.
Who Should Get an Energy Audit?
Energy audits are especially valuable for homeowners who:
- Have high electric or gas bills
- Experience hot or cold rooms or moisture issues
- Own older homes, Cape Cods, split-levels, or homes with rooms over garages
- Notice condensation on ductwork
- Plan to upgrade HVAC or insulation
Does the auditor also do the improvements?
Typically, yes. The same company that performs your energy audit will normally have in-house crews who can handle the recommended upgrades. That means no middlemen or guesswork. After the audit, their team can complete improvements like:
- Air sealing and insulation (attics, crawlspaces, walls)
- Duct sealing and ventilation adjustments
- Kitchen and bath fan venting
- Storage platform adjustments to increase insulation depth
- Crawlspace encapsulation
- Minor HVAC and water heater upgrades (or coordination with trusted subcontractors)
This “audit-to-upgrade” model ensures a seamless process and allows the company to apply for rebates on your behalf, since they’re a participating contractor with Pepco and BGE. You get a single point of contact from start to finish—and better accountability for the results.
Final Thoughts: Don’t Let the Next Season Catch You Off Guard
If your energy bills felt out of control this past winter, an energy audit can give you answers—and a roadmap to lower costs, better comfort, and a healthier home. With record-breaking heat expected this summer, now is the perfect time to identify and correct inefficiencies before your A/C starts running non-stop.
You’re already paying into these rebate programs—put that money to work for your home.

FAQs About the Energy Audit Process
❓ What does the attic inspection portion of an energy audit involve?
The attic is one of the most important parts of the audit. The auditor checks:
- Insulation depth and condition (anything under 17 inches is below code)
- Penetrations like open chases, junction boxes, plumbing and wire holes, bath fan vents, attic stairs
- Whether bathroom or kitchen exhaust fans are improperly vented into the attic
- Ventilation setup, including soffit vents, gable vents, and attic fans
They’re especially focused on places where hot or cold attic air may be infiltrating your living space—like around attic hatches or unsealed top plates.
❓ What is a blower door test in an energy audit?
The blower door test uses a powerful fan mounted in an exterior doorway to pull air out of your home, creating negative pressure inside. This exaggerates where outside air is entering, so the auditor can:
- Feel leaks around windows, doors, and penetrations
- Use thermal imaging to show hot or cold air movement
- Identify leaks traveling from the attic into wall cavities and out through outlets and switches
❓ How is infrared imaging used in an energy audit?
Infrared imaging is done during the blower door test to spot areas of significant heat gain or loss. Common findings include:
- Ceiling registers connected to the attic (can be as high as 100+ degree zones in summer!)
- Uninsulated attic hatches or stairs
- Wall cavities behind outlets or switches due to unsealed top plates
- Missing insulation in knee walls, cantilevers, and crawlspaces
❓ What is combustion safety testing?
If you have gas appliances like a furnace, boiler, or water heater, the auditor’s assistant performs combustion safety checks, including:
- Backdraft testing to ensure flue gases are venting properly
- CO testing (carbon monoxide) in both flue and ambient air
- Gas sniffer checks for leaks
❓ What kind of data is collected during a home performance energy audit?
In addition to blower door and infrared data, the auditor will:
- Measure the full square footage and volume of conditioned space
- Record the type, age, and size of all HVAC and water heating equipment
- Review your utility bills and plot your usage against homes with similar square footage and heating types
❓ How long does a typical home energy audit take?
Most audits take between 2 and 3 hours, depending on the size of the home and how many issues are found. The process is detailed and includes multiple types of testing, equipment review, documentation, and homeowner consultation.
❓ What do I get after an energy audit?
Within a week, you’ll receive a personalized package that includes:
- A detailed energy audit report
- A prioritized list of recommended improvements
- Estimated energy savings
- Rebate eligibility, often totaling thousands of dollars
- A professional proposal for completing the work
