"I was very pleased with the audit which helped to identify needed fixes. As a result, last winter was a much more pleasant experience at home and we used less propane"

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.

"We had a whole house Generac generator installed by K Hanrahan in August 2021. We were beyond pleased with their prompt and efficient service. They handled the whole process from planning to permitting and installation. Everyone in their company was efficient and friendly. I highly recommend them."

"Ira was cordial and professional. He has practical experience and knowledge of residential energy audits. He was able to provide useful suggestions but not definitive solutions to issues. That may have been due to inaccessible interior walls. I am frustrated that a full written report that had been promised still has not been produced six weeks later."

"I hired Eco Green because I know people that have used them with no complaints. They were on the ball with everything. Fast, informative and ready to help. I had a hose break free from my washer and it flooded my office with 2 inches of water, the unit below us and the 3 floors below them. Within hours their team was in my unit, the water was up, the dehumidifier and industrial fans were running. Hours later, things were dry to the touch. By the next day, the floors didn't squish. We have no mold, no funny odors and they were able to save my wood floors by acting so quickly. If you value massive experience and the right tools for the job, Eco Green is your last call.

"My husband and I are first time home buyers and we thoroughly did our research before choosing a home inspector. We are more than pleased with Igor's professionalism and quality of work. He took his time with us and explained everything. Most importantly he gave us pointers on how to maintain our house after we purchase it. Igor is extremely knowledgable and thorough in everything that he does. In fact our real estate agent thought he was great as well and now she recommends him to other clients as well! Defiantly go with Igor from Eagle Eye Inspections, you would not be disappointed!"

"After I called for an estimate, Joey came promptly and assessed our insulation needs. He took his time to explain everything and also gave valuable energy savings tips. We scheduled a date and he and his crew arrived on time and insulated our attic. Within a couple of hours they were done with a thorough clean up."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

Energy Efficiency Auditing questions, answered by experts

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
