"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?"

"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."

"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!"

Energy Efficiency Auditing questions, answered by experts

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

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.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
