"John was excellent to work with. Very thorough in his pre energy inspection as well with post inspection. Without John s work the insulation crew would have had a difficult time finding the problem areas. Highly recommend for ANY insulation work."

Energy Efficiency Auditing questions, answered by experts

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

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.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.
