You Asked, We Answer: Is a Home Energy Audit Worth It?

December 06, 2022

Ever done a double take when you took a look at your last energy bill? While high energy bills can be the end result of intense weather conditions, repeatedly high bills can often signify an inefficient HVAC system or your home is using too much energy by other means, including drafty windows or insufficient insulation.

One of the easiest ways to figure out whether your home is consuming too much energy is by calling a home service professional to carry out a home energy audit, also known as a home energy assessment. Keep reading to find out more about home energy audits, including what they are and their advantages.

What Is a Home Energy Audit

An energy audit is a comprehensive inspection of how much energy your home consumes and whether – and where – your home could be losing or wasting energy. An inspector will go through older energy bills during an energy audit to determine where energy is being wasted and how much.

The overall goal of an energy audit is to help homeowners save money on their energy bills by recommending energy-efficient renovations, which may include swapping out your existing HVAC system, putting in new insulation, plugging up leaks, or replacing loose windows.

While completing the energy assessment, the auditor carries out an inspection of the outside and inside of your home. The auditor performs a blower door test on doorways, windows and fireplaces to figure out if there are air leaks in your home. They’ll also check your home’s HVAC system, which also includes the ductwork, the water heater, and the insulation in your attic. Some assessments might also include checking your current lighting system.

Benefits of a Home Energy Audit

It can be hard for the average homeowner to be sure how efficient their home is compared to other similar homes in their area. However, lots of energy companies often offer information about where your home ranks when compared with similar homes and whether it’s more efficient, about average, or inefficient versus your neighbors’ homes. This can be a useful starting point to figure out if you need an energy audit completed.

A few of the benefits of a home energy audit include:

Recognizing How Efficient Your Home Is

It’s beneficial to learn more about how efficient your home is and where you’re consuming the most energy. For example, if your ducts are damaged, it could lead to a large increase in your energy bills and increased wear and tear on your HVAC system because it has to run longer to properly heat or cool your home.

Making Energy-Efficient Updates

An energy audit can outline where you need to make energy-efficient upgrades to cut back on energy and reduce utility bills. This may include replacing old weatherstripping or getting a new energy-efficient furnace.

Improving Health and Safety

Permitting air to slip into your home through doors and windows, or due to a lack of insulation can cause excessive moisture to appear, which can negatively impact your home’s humidity levels or lead to mold. This can exacerbate health problems, particularly for people suffering from asthma or allergies.

Adding to Your Home’s Retail Value

Energy-efficient homes are preferred by homebuyers. You can sell your home more quickly or for more money by telling prospective buyers that it’s energy efficient.

How to Perform an Energy Audit of Your Home

Although handling an energy audit by yourself might not be as thorough as hiring a professional, it’ll give you a broad idea of how energy efficient your home is. If you don’t discover any flaws during the DIY test, then you probably don’t need to bring in a professional. Use this step-by-step checklist:

  • Examine your HVAC system. Leaky ducts can lose nearly 20% of conditioned air, contributing to more expensive energy bills and increased wear and tear on HVAC equipment. If you discover leaks, use duct tape to eliminate them. If your HVAC equipment is old and wearing down, upgrading to a new system can save you a significant amount on your energy bills. In some cases, it is better to contact a reputable HVAC company in Lafayette to inspect your system.
  • Check for air leaks. Air leaks on average can raise the energy bills by 10 to 20%. Inside, look for air leaks in areas where you can find a draft, like along the edge of flooring and along baseboards and electrical outlets. Outside, you can look for air leaks around the home’s foundation, siding and mortar. Plug, caulk or seal any air leaks to save money.
  • Inspect insulation. If your home is older, it could mean your insulation is too. If you can see the joists, you likely need more insulation.
  • Check the ventilation. Make sure that all of your kitchen and bathroom exhaust fans are functioning properly, and look for evidence of rot or moisture.
