I conduct energy audit tests for homes, whether they are colonial or brand new construction. I can recommend you various forms of weathersealant, thermal wrappings, and storm window techniques, saving you thousands in the form of long-term heat insulation tech-forward solutions.

"Our house was brand new - only 1 year old. Since moving in I had been very sick with lots of ailments - nausea, light headed, constant sinus/ear infections, dizziness and vertigo. We had high end all wood floors, kitchen, etc. After many, many medical exams and tests showed no cause and the so called "experts" had no suggestions - we consulted with Bob. Luckily our air quality tests showed no mold - but showed "debris" such as VOC's, etc. from a newly built home. Since our new home was made extremely tight and energy efficient, the poor air quality could not escape on it's own. Bob "scrubbed" our air. I felt immediate improvement in my health and within a week's time - all symptoms of chronic stuffiness, dizziness and other were gone. Back to having fun and breathing well! I had no idea I was so allergic to VOC's, etc. Bob was just superb. Thank you!"

"They did an excellent assessment, were good listeners for our goals, gave us updates as to when the custom windows would arrive, installed promptly and expertly respecting our time limits due to our children's nap schedule, cleaned up, communicated with us through the installation, and we have had reductions in our energy bill since the installation.

We are NOT owned by a trade or supplier, thus we will provide you all the options you need to effectively make your home more energy efficient \nWe have considerable experience in building energy efficient homes and in using the different technologies, modular, timberframe. SIPS, ICF and 2x6 panelized to build a home. This experience makes it easy to identify problem that are caused by the specific construction. Without this experience opportunities will be missed.

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.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.
