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

December 06, 2022

Ever done a double take when you viewed your last energy bill? While high energy bills can be the result of severe weather conditions, repeatedly high bills can quickly indicate an inefficient HVAC system or your home is misusing energy by other means, including drafty windows or inadequate insulation.

One of the easiest ways to figure out whether your home is using too much energy is by hiring a home service expert 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 key elements.

What Is a Home Energy Audit

An energy audit is a thorough inspection of how much energy your home uses up and whether – and where – your home might be losing or wasting energy. An inspector will take a look at older energy bills during an energy audit to figure out where energy is being used and how much.

The general goal of an energy audit is to help homeowners save money on their energy bills by suggesting energy-efficient improvements, which might include swapping out your existing HVAC system, putting in new insulation, closing up leaks, or replacing old windows.

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

Benefits of a Home Energy Audit

It can be hard for the typical homeowner to know for certain how efficient their home is in comparison to other similar homes in their area. However, many energy companies often offer information about where your home stands when compared with similar homes and whether it’s more efficient, about average, or inefficient versus your neighbors’ homes. This could be a great starting point to decide if you need an energy audit scheduled.

Some 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 leaking air, it could result in a sizable increase in your energy bills and increased wear and tear on your HVAC system because it has to stay on longer to properly heat or cool your home.

Making Energy-Efficient Improvements

An energy audit can outline where you need to make energy-efficient improvements to conserve energy and decrease utility bills. This can include replacing worn-down weatherstripping or getting a new energy-efficient furnace.

Enhancing Health and Safety

Enabling air to seep into your home through doors and windows, or as a result of a lack of insulation can cause excessive moisture to form, which could negatively impact your home’s humidity levels or lead to mold. This can lead to health conditions, particularly for people dealing with asthma or allergies.

Adding to Your Home’s Retail Value

Energy-efficient homes are desired by homebuyers. You can sell your home more quickly or for more money by demonstrating to potential buyers that it’s energy efficient.

How to Complete an Energy Audit of Your Home

Although handling an energy audit by yourself might not be as thorough as calling a professional, it’ll offer you a generalized understanding of how energy efficient your home is. If you don’t find any problems during the DIY test, then you probably don’t need to bring in a professional. Use this step-by-step checklist:

  • Inspect your HVAC system. Leaky ducts can lose up to 20% of conditioned air, resulting in steeper energy bills and greater wear and tear on HVAC equipment. If you find leaks, use duct tape to close them. If your HVAC equipment is old and inefficient, upgrading to a new system can save you a significant amount on your energy bills. In some cases, it can be better to contact a reputable HVAC company in the Bay Area to inspect your system.
  • Look for air leaks. Air leaks on average can raise the energy bills by 10 to 20%. Inside, look for air leaks in areas where there is a draft, such as along the edge of flooring and close to baseboards and electrical outlets. Outside, you can look for air leaks in 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 spinning properly, and look for evidence of rot or moisture.
