"Robert Moore was very knowledgeable and experienced when he did the home assessment. He knew exactly what our attic needed. Then when the crew arrived a week later to do the job they were fast and efficient. Best part was they were very neat and organized when they were performing the work. Would recommend Arc insulation to all my friends and family."

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

"He was prompt and professional. made a complete inspection. explained everything in detail. estimate was completed in appropriate time frame. Price came in a little above my expectations. I did not have the work done because I have several major projects going on for my house. This gave me the information to prioritize and plan my work. Will possibly use him if and when i do this part of renovation."

Energy Efficiency Auditing FAQs, answered by experts

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

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.

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

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.
