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.

"

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.

"I live in and own a 2-family home that has flat rook and that is located in the Bronx, NY. I live in the lower unit and my tenants live in the upper unit, which is right below the roof. Our current and previous tenants would often complain that the rental unit felt cold when the temperature outside fell and my wife said that even when the indoor temperature in that unit was high, the unit felt drafty, which can make the unit feel colder than it actually is as the heat escapes through the roof rapidly. A contractor who installed kitchen for us in that unit told us that our roof had absolutely no insulation- something he saw when he installed the exhaust for range hood. So last year, I decided to call this company for a quote. My hope was that insulating the roof would significantly decrease the release of heat, which would make the unit warmer and reduce airflow (i.e., drafts). When I called, a really nice receptionist answered the phone, took my information down, and answered a few questions, and told me that the owner, Joe, would call me back either the same day or the next. The reason for this is that Joe is usually out doing roof insulations himself. When Joe called back, I was quoted a price of $3.00/square foot, but decided not to go ahead at that time. He was very nice and polite and is willing to answer lots of questions. He seems really passionate about his work and will describe in pretty significant detail what he does. This year, we decided to pull the trigger so we called back and received a quote of $2.50/square foot- a savings of $500 to insulate our 1,000 square foot roof. As you can imagine, that made me happy. We spoke on Friday and set up an appointment for Wednesday (5 days later). Joe and one of his workers arrived with their truck at 7:30 am and were finished by 9:45 am. The process was so much faster than I could have imagined. And, they didn't even have to come inside the house! Joey and his worker used a 40-ft tall ladder to scale the front of the house (it's 3 stories high) and to take their equipment up to the roof. Once up there, they used an electric saw to make a hole (they might have made 2) through which to blow in the insulation. The noise from the saw lasted about 10-15 minutes, after which the work they were doing was relatively quiet. I was actually really amazed at how non-intrusive the whole thing was and how quickly the job was completed. Joey made sure to show me exactly what kind of insulation he was using and gave me written materials about the product he was using (blow-in fiberglass). If Angie's List lets me update this review, I will definitely write back once we have experienced the insulation in cold weather to describe how well it is working."

"They put in a switch box for our generator. They had to come back a couple of times because it did not pass inspection. Part of their proposal was for proposal and at the end of the job I ask them for a copy of the permit and apparently that had not gotten a permit."

"We were trying to sort out electrical issues as part of a home inspection, and Mister Sparky provided an estimate for service that was actually unnecessary.  Thus, we went with another company that accurately diagnosed the issue and gave an estimate."

"Very well. The guys from Clover were great. They identified many problems in my home that were costing me money in heating bills and greatly reducing energy efficiency. I have seen a big improvement in my energy bills as a result of this project."

Energy Efficiency Auditing FAQs, answered by experts

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

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.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

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.
