"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."

"

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.

"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."

"The folks from Weather Busters came out to my house a few times to understand the problem and even tried some temporary fixes. Eventually they helped reduce the noise by putting some foam padding along the basement pipes but it did not eliminate the noise. They were very friendly, very courteous, and genuinely nice guys. They said they would send a proposal for getting the noise fixed permanently as well as a proposal to replace our old furnace. After investing all of this time and energy you would think that they would be super responsive when it came time to sign me on as a client. Not So. I had to chase after them several times before I got a proposal in the mail. When it finally arrived, it was only a proposal for replacing the furnace. This was not my big concern and I had only agreed to see this proposal as a consideration for a later time. My urgent request was to fix the noise so that my 3 month old baby and recovering wife could sleep better. I chased after them again for a proposal to fix the noise but nothing was sent. To this day I never heard back on this proposal. I was fully ready to give them the business based on their wonderful service but they lost my business by not closing the deal and getting me the proposal I needed. After chasing them for a month I ended up going with another company who came out and fixed the problem all within the same week. Sorry Weather Busters but you lost a potential client for life. "

Energy Efficiency Auditing FAQs, answered by experts

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Audits typically take 2-4 hours, depending on the property size and energy systems.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.
