Home Energy Assessment

Find out how you’re using energy & how you can save money.

Most homes have areas where energy is wasted or overused — and wasted energy costs money you could be keeping in your pocket. A home energy assessment can help identify the best and most cost-effective strategies to reduce your energy bills — and consumption — by up to 30%. It pinpoints energy “leakage” and how to fix it through things like weather-stripping, insulation, heating and cooling tune-ups, etc.

An energy assessment report gives you a list of things you can do along with estimates for cost, savings potential, and payback period. Many utilities are also now offering energy assessments at a reduced price.

All utilities serving Montgomery County offer Quick Home Energy Check-Ups (QHECs), often for free. They’re not as detailed as a full assessment, but can identify some quick energy-saving options. And many of these check-ups will offer you free energy savings products such as efficient lighting and water heater blankets as part of the visit.

How does a home energy audit save me money?

It all depends on what you do after you get the audit results. Every action you take to improve energy efficiency helps reduce your utility bills. Click here to learn about different home energy improvements, and how each method can save you energy and money.

How much does a home energy audit cost?

There are two basic types. A basic “walk through,” or Quick Home Energy Check-up, where a specialist goes through your home and identifies opportunities for energy-saving fixes or enhancements (such as weather-proofing, changing lighting or upgrading appliances) is usually in the neighborhood of $40. Many utilities offer check-ups for no cost if you take advantage of low-cost fixes that will be offered to you onsite.

A more robust assessment may include a blower door test and/or thermographic scan, which more precisely pinpoints exactly where hot or cool air are escaping from your living space, indicating the need for more insulation or other measures. These can cost $350–$700.

Utility companies often offer incentives for all these types of tests. Click on the “Incentives” tab above to see current offers.

How do I find a contractor who is qualified to do energy improvements?

Click on the “Resources” tab above for several web resources that can help you find a certified or accredited auditor in your area. Be sure to choose one that works with your utility so you are eligible for incentives for select improvements.

I live in a condominium.  Can I still get an audit?

A full-scale assessment may not be your best choice, unless your management company can organize an audit for the whole building. However, a Quick Home Energy Check-Up from your utility can help you to identify quick energy-saving opportunities. Check the Resources tabs for information about audit opportunities for condominiums from your utility. Talk to your management company and condominium board if you think your building could use a full-scale audit.

    Today 2 people knocked on my door doing a survey for energy saving for Pepco…I did not schedule an audit.

    If Pepco is going to be auditing my neighborhood, I would appreciate an email “heads up” as I turned these two people away. They did not provide me with any identification when introducing themselves to me.
    They wanted to see a copy of my Pepco bill, which I did not provide to them.

    The typical power company audit is more a conversation and visual inspection. A blower door test is more indepth and telling but obviously comes with a price tag. A great in-between option is thermal IR test. You can visualize thermal boundaries, barriers, and bypasses and will usually present you a some obvious areas of concern to tackle first.

      There are two options for homeowners, as you mentioned. The Quick Home Energy Checkup is a fast, easy way to reduce energy use in your home and save money. The QHEC allows homeowners and tenants to get energy efficient products such as LEDs, efficient-flow showerheads and smart strips installed at no additional cost to their usual utility bills. As existing customers of utility companies, owners and tenants bear no additional cost for these energy conservation measures.

      The more comprehensive option, with the blower door test is part of the Home Performance with Energy Star Program and is a $100 Home Energy Assessment. Using state-of-the-art equipment, a specially trained Participating Contractor trained and certified by the Building Performance Institute will:

      – Conduct a comprehensive Home Energy Assessment, including a complete visual inspection and diagnostic tests.
      -Provide a Home Energy Assessment Report that includes recommended improvements specific to your home, as well as projected energy savings.

      Both of these are available through your utility supplier!
