"We have had NECS to our home several times for different projects: energy audit, attic insulation, and wall insulation. These are very professional, considerate, and honest people to do such work in your home. Our house is much more energy efficient after all we have done. Insulation pays for itself very quickly, and NECS took care of all incentive programs for us. You won't go wrong with them."

"The service was great. They gave a lot of really helpful suggestions. They replaced our bulbs with low energy bulbs. They put in weather stripping in areas needed as well. They were great to work with. They gave a detailed report on how to lower our energy usage."

"HARP gave us text and email notices prior to arriving, including a photo of our technician so we knew who to expect. He was very thorough and did a great job cleaning and inspecting. He did find a rusted part that needed to be replaced, which he did during the same appointment. Received in-time estimates and invoices by email so we were very clear on what we were getting an paying for. Very professional and supportive of clear electronic and verbal communication. Would definitely recommend to others."

"We lost our hot water.  We had no idea what was wrong and at first neither did Taylor energy, but they kept coming back (in a very timely manner) and trying to fix it.  When all was said and done they did a great job, quickly.  They were very considerate to our plight and they were very fair in their pricing of what was fixed.  We have used them ever since we bought our house and have, to this date, always been happy with their services."

Energy Efficiency Auditing FAQs, answered by experts

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

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.

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.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.
