"Had the best experience with Tom and his team! I obtained three estimates for the work, and Tom spent the most time of any of them reviewing the attic, taking measurements, and speaking with me about his recommendations. The crew was fantastic as well - and they cleaned up after themselves each night - which I appreciated very much. The work was not rushed and was done well. I only wish I had another need to use their services because it was such a positive experience. I highly recommend!"

"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."

"Went well. Gary the technician was very professional and personable. He inspected the 23 year old system, provided me with a detailed explanation of what he found with recommendations for the future. Left me a written report. For this upcoming season, I should be OK. Would definitely hire Green Heating, Cooling, Electrical again."

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.

"The contractor came even earlier than expected and spent over 2 hours looking at my home. Needless to say, his suggestions to improve energy efficiency were numerous, some more costly than others, some things that I could do on my own. The estimate I got from this company was in line with another insulation company's estimate. I'm uncertain which of the two companies I'd go with, though. The $25 charge for an estimate was more than I'd usually pay for an estimate (ha) but he had lots of information and didn't mind all of my many questions. A good place to start if you're wanting information.

"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 FAQs, answered by experts

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.
