Pepco Home Energy Audit Guide for 2025
Everything You Need to Know About a Pepco Energy Audit
Often homeowners don't know what a Pepco energy audit is or how it can help you understand energy waste in "three-dimensional" ways.
For example, an incorrectly installed bathroom exhaust fan will inevitably cost you far more in annual energy waste than perhaps all of the windows in your house.
Here are three benefits you'll get from a comprehensive home energy audit through the Pepco Home Performance with ENERGY STAR® program:
1. It can help you avoid choosing the wrong solution to a problem you are having
2. A Pepco energy audit is a great way to organize your home improvement priority list
3. It will undoubtedly guide you, or someone you know, to a more comfortable home
This article breaks it down for you and shows how getting the audit done can open your eyes to a few unexpected things!

Approved Pepco Energy Audit Contractor

There are only a select few contractors in the state of Maryland that qualify to perform a Pepco energy audit within the Pepco weatherization program. An approved auditing company in the program has a unique skill set.
Two certifications are critical to understanding the audit process and being accepted into the program. A contractor that carries a Building Analyst certification can identify energy issues. The Envelope Professional designation means that we also know how to fix problems.
Most contractors know how to sell you what you want and install what they sell. Pepco energy audit-approved energy firms know how to show you what you need and install it so it makes a difference.

How a Typical Pepco Energy Audit Will Flow
Hour 1 - Meet & Greet
First, the auditor needs to learn about what is happening with your house and what makes you interested in getting the audit done. You can give the auditor a tour of the house. You and your auditor should discuss any details or items of interest you might want to share.
Hour 2 - Auditor Data Collection/ Testing
Every auditor has their style and method. Data collection is a very important part of a home energy audit, and a house can be pretty complicated. Typically hour two is spent apart from the technician so that accurate information can be collected through testing and measurements.
Hour 3 - Attic Inspection/ Blower Door Test
Once all information from the key places around your home, including your attic and crawl space, has been collected, the only test left is the blower door test. The blower door test is an excellent opportunity to walk around the house, perform a physical inspection, and review all findings. This way, when reporting is provided, the information in the paperwork will align with what you see around your home on the day of the audit.

Why Do You Need a Pepco Energy Audit?
A great way to significantly reduce energy waste is to tighten up your house's envelope. When sealing is done correctly, your HVAC runs less, pests have a more challenging time getting in, and you feel more comfortable. Knowing where to look and how to accomplish improving your "building's shell" is the central focus of a Pepco energy audit.
A Pepco energy auditor will investigate areas of your home that typically do not see much "daylight." The dark places and small spaces sometimes yield the most information. Getting a Pepco energy audit to have a trained pro to check out the attic is well worth the small investment of $100!
Get questions answered, such as:
- How much insulation is needed in your attic?
- How do you properly vent your crawl space?
- Should you remove old insulation from your attic?
- What is the best way to seal your crawl space?
- Is spray foam insulation the best solution for your home?
- Why are your windows feeling drafty?
- Should you insulate the walls in your home?
- What areas should you seal to reduce drafts?

What Kind of Service is a Pepco Energy Audit?
Not every contractor in Maryland qualifies to perform a Pepco energy audit. Improving your home's building shell tightness is not as simple as adding more insulation.
Energy auditors have to be certified as Building Analysts to identify what a house needs. Calculating the number of air changes per hour your house loses uncontrolled to the outside is part of the assessment. Check out examples of interesting things we find tied to air leakage here.
A Pepco energy auditor evaluates your house as it stands now. The auditor accurately takes a "snapshot" of your home's energy performance.
Health and safety testing, pressure readings, and an air leakage test are all data points needed to complete a Pepco energy audit. Other evaluations depend on age, symptoms,s and preexisting conditions.

What Does a Pepco Energy Audit Test Around Your House?
Health & Safety Testing
Several health and safety tests are performed during a Pepco energy audit. You can expect the following:
- Combustion testing of any gas appliances
- Carbon monoxide testing
- Gas line leakage testing
A gas leak was detected and confirmed at this Maryland residence.
Air Flow Testing
Ventilation is essential to healthy living and must be part of the overall plan to improve efficiency.
- Measure exhaust fan ventilation speed
- Blower door testing
- Duct leakage testing
Take the smart step and schedule your Pepco energy audit as soon as you can! It is a steal at $100!

How Can a Pepco Energy Audit Give You a Check-In on Your Home's Indoor Air Quality?
Indoor air quality is commonly misunderstood as a number calculated in particles. Instead, it refers to getting fresh air into a home.
A Pepco energy audit is a great way to determine your indoor air quality "score" and how to fix any deficits that may exist. A great way to determine indoor air quality is to consider a common misconception.
An excellent carpenter who works around houses every day once said to me during a discussion about air sealing a house:
"Well, gee, don't you need to let the house breathe?"
This comment has a direct tie to indoor air quality. The answer is, YES, of course. But, we need to discuss the difference between uncontrolled and controlled "breathing."
A Pepco energy audit, using sophisticated modeling software, calculates the required air changes per hour for each home that is inspected. A Pepco energy audit looks to tighten a building's shell, therefore calculations are made as the house stands now and projections are calculated if the house is tightened.
The great thing about the Pepco energy audit is that you can find out your indoor air quality status now without having to do any additional work. Some houses are too tight before any measures are taken, and the occupants are happy to know there is a deficit and how to remedy the issue. An energy audit consistently delivers solutions that give the homeowner complete control.

What Does a Pepco Energy Audit Look for on the Exterior of Your Home?
A walk around the perimeter of your home by a certified auditor is an essential part of taking a whole-house approach to remodeling. Uncovering issues that have gone unnoticed is an effective way to prioritize your home remodeling projects.
For example, if downspouts are not adequately extended from the home, recommendations on how to remedy the issue will be provided to keep water away from the foundation wall.
Other areas of importance are siding, windows, doors, HVAC, and trim. Looking at ventilation areas outside the home will also help you prioritize your following home improvement projects.

A Pepco energy audit has one primary purpose: to tighten your home's envelope. This means to let less air leak in or out. Insects travel in and out through the same pathways.
The answer is yes! A Pepco energy audit will search your entire home for air leakage. Taking advantage of the available incentives to get the work done will also help reduce pests.

Will the results of a Pepco energy audit save you money?

A Pepco energy audit will save you money - no questions asked! Upon your initial inspection, the auditor will install energy-saving measures. This will help you save right away!
On a grander scale, the answer gets more complicated. Many factors must be in the equation to determine an answer.
For example:
- How long will you live in the home?
- How much work does the home need?
- What type of fuel do you use for heating and cooling?
A Pepco energy audit is the absolute best way to figure out the answer to the question. That is the design of the program. The audit is the analysis step. Information obtained during the audit can set a pathway to comfort and efficiency.

What Types of Recommendations Come Out of a Pepco Energy Audit?
If you believe that improving comfort and efficiency is as simple as adding insulation to what you have, then a Pepco energy audit is something you should strongly consider.
A typical prescription for tightening up a house and making it more efficient will include caulking, air sealin,g and weatherization treatment to the attic hatch. Walls accessible in the attic (knee walls) may be recommended for treatment,t and the basement rim joist is a big opportunity in unfinished areas.
Each home is different, and the "low-hanging fruit" is different for each home. A good auditor will find differences in the same model in the neighborhood. A Pepco energy audit takes a snapshot of your home's insulation levels around the house, reports on them,, and recommends how to improve the boundary locations.

Conclusion
Residential houses and commercial buildings account for approximately 39 percent of U.S. energy consumption.
Energy consumption within a building is made up of many parts; the building envelope is the most significant factor in what part of the usage is waste. The envelope serves as the barrier between the inside and outside.
A Pepco energy audit evaluates your home's envelope and finds easy ways to tighten things up. A Pepco energy audit can lead to more home comfort and smaller energy bills.
