"Spectacular! I had solar installed and Trevor was super helpful with the process. He made all the complicated paperwork easy. Just like that we have solar and I'd never go back! Double thumbs up for Trevor!"

"We purchased the home energy audit with the understanding that we would be receiving a more extensive analysis of our home energy usage along with possible solutions. Ultimately, the process was more about a presentation for solar panels that anything else, which was not what we were looking for when we purchased the offer. Richard was very professional and thorough in his presentation and presented options regarding areas to save in terms of energy usage but those areas were not as thoroughly explored as the solar discussion. Green Source Energy should be more direct about what the Home Energy Audit entails so buyers can make an informed decision."

"This was the absolute best company I could have ever chosen. They are not your average insulation company, they are a energy efficiency or home performance company so they are actual certified building scientists ! Air sealing the Attic flat and insulating the attic properly saved me 20% on my utility bill !"

Energy Efficiency Auditing FAQs, answered by experts

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.
