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.

"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."

"

Eco Green Solutions were great to deal with.  They came to the home for an initial consultation and provided me with great solutions for the heat loss problem I had in the home.  The salesperson provided me a clean understandable proposal with different options I could choose from depending on my budget.

When we agreed upon the scope their office scheduled an appointment with me to schedule the work.  Their crew showed up on time, wore booties on their feet to keep my floors as clean as possible and did a remarkable job patching and priming the walls for painting.  I wasn't home when the work was performed, but the painting contractor I had in the home at the same time commented on how professional they were and how they made his job so much easier.

As a homeowner, heating and cooling cost are real concerns.  I highly recommend anyone considered with those things like I am to have Eco Green Solutions do an energy audit of their home and see where they can save.

"Joe did a great job on this, our dining room was a add on to connect the original home and the garage and had no insulation and boy in the winter it was unusable as well as the kitchen basically (the best part of the house). Joe came and drilled small holes in the attic floor that they sealed up later to allow for blowing in the insulation. And they cleaned up well. we have a 20 month old but there was nothing left over for the baby to put in her mouth. Joe is great! Our dining room is toasty and the kids can play in there year-round Plus they are were less than half of the expensive "efficiency" guys PSEG sent over. Those providers wanted to charge $10,000+ for basically the same job."

"The work he did was good but they did charge too much for the work. They did try to upsell other services. The charge for the additional work was too much. The charge for the part was very high. I did not have them do the additional work."

Energy Efficiency Auditing FAQs, answered by experts

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

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.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.
