His services were very much appreciated and very professional. Lee"

"Ryan was patient and allowed me to ask questions and did not pressure me. If I get approval, from HOA, will hire Ryan to do my solar on the condominium. If approval is not met with the HOA, I will be referring him out and using Sunpower on my next single-family home purchase."

Energy Efficiency Auditing questions, answered by experts

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.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

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.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.
