"I looked for a local building scientist to examine my very large, leaky and complex house, recommend and install ecologically sound insulation. John was not the cheapest, but he noticed a number of things about the house that others missed, and he was very willing to explain my options in great detail. I had a lot of confidence in his company, and I am very pleased with the results. The crew was very professional, organized, hard-working. They checked the blower door data after every major portion of the work, and exceeded their targeted reduction in CFM 50 by approximately 2-fold."

"We had purchased a de-humidifcation system for our basement through Frank Petrullo a few years ago.  Once installed, gone were the days of having to constantly empty the bucket from our old stand alone unit.  The new system was operating without a hitch until suddenly, it ceased functioning.  We called Eco Green and explained the problem.  Frank made sure that a service appointment was scheduled promptly.  We didn't have to wait around for the technician to arrive as he came to our home as scheduled.  The problem was identified - the culprit was our cat, who had taken a liking to the  tubing and had managed to damage the system.  There was little doubt in the technician's mind as to what had happened since our cat was kind enough to attack the unit in his presence! 
The Eco Green technician devised a solution to protect the unit from our cat allowing our unit to resume functioning and keeping our basement dry.  
We are very happy with the customer service and attention that we have received from Eco Green and gladly recommend this company.

"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."

"It went well at the time. The furnace installation price included a 3 year service contract for my 2 ac units and 2 furnaces.  I have had 3 maintainance  services so far which were ok.  Now they seem to have gone out of business for the last 4 months.  I am still due 3 more included  maintainance  service calls.   Are they coming back in business or am I out the money and hire someone else?"

"They got here in a short period of time. They were done in a couple of hours, end of story. They were very clean.  I am satisfied with their work, it is wired correctly and everything is up to code and done in a proper manner."

"Excellent experience from start to finish! The home energy audit showed me where I was losing heat and areas that needed attention. Getting the house sealed and getting blown in cellulose and an attic cap installed professionally is something I would recommend to any homeowner. Expediant energy came to install it soon after the initial estimate. which in this winters bitter cold temps is something I really appreciate. I Noticed the difference immediately. Anyone who is paying for heat and looking to improve their insulation should give these guys a call you won't regret it!"

"Arrived 1 hour late. Said they were bringing parts Brought "guts" for toilet flushbox. Didn't need it. Five minute repair had toilet working again. Brought bathroom faucet with them. Did not bring kitchen faucet which he said he had when we spoke. So the went to Home Depot and came back with faucet. He then proceeded to install both faucets. He then told me I owed him $900.00 which I was not prepared for. And I told him so. Angi's estimated a repair for somewhere around $342, I think. I had $550.00 put aside for the job. I gave him that. I usually keep $200.00 at home for emergency. Gave him that as well. Since he still didn't seem satisfied I wrote a check for the final $150.00. He said make it out to cash. And check HAS been cashed. I felt completely intimidated. I'm 82 years old and live only on social security. I have never felt so 'taken advantage of' in my life. And since my name will be provided to them, I guess I now need to be afraid of retaliation. A bit scary. But I need to do this anyway. If only to save others from the same fate. He actually had the audacity to charge me $100.00 for the toilet repair which, as I said, took 5 minutes. That's $20.00 per minute! After they left I went on Home Depot's website. The bathroom faucet retailed for $27.00. He charged me $50.00. The kitchen faucet retailed for $89.00. He charged me $150.00. On the phone I was told how 'fair' they were. No way!"

Energy Efficiency Auditing FAQs, answered by experts

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.

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.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.
