"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"Green Audit performed a home energy audit on my home. I originally purchased the deal they offered through Angie's List for $75, but was informed by Green Audit that the audit can be done for free provided by funding through PSEG so Green Audit refunded the $75 and there was no charge for the audit. Matt and Richard performed the audit. I thought they were very professional and provided a lot of useful information. After the completion of the audit they provided me with an estimate for recommended efficiency work and a ROI summary of what the work could save me in money over time. The estimate they provided was extensive and included a lot of items for energy efficiency, some of which you would not get from a typical insulation company, I thought their pricing was a bit on the high side and I decided not to use them."

"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.

"Powersmith (Mike and his team) was the most professional, courteous, clean and prompt group of plumbers we have ever had the opportunity to work with. They arrived EARLY to perform the job both days.  The job which was a very large one, included removal of our old oil system including the tank, prepping of our chimney, installation of our new gas burning system.  Each team of workers was more efficient than the next.  The first day the Salesperson, Joe came to our house, we knew they were the ones for the job.  They operated like a (pardon the pun) well operated machine.  They were so professional and looked genuinely happy to be here (which is very rare these days).  They left our house looking as if nothing was even done (and this was a huge and dirty job). This was a costly, long and well thought out change for us and we interviewed no less than 5 other plumbers from all over Nassau County. We are SO happy we chose them.  I would recommend them to anyone and wouldn't hesitate to call them in the future.  Thank you Powersmith!"

"Joey Jacinto was prompt, courteous, and happy to share his extensive knowledge. With his infrared camera we could see where the major loss of heat was occurring. Much to our surprise, our walls turned out to be insulated and the attic insulation was adequate. Our main problem was the old wooden windows which we are planning to replace, and one or two small house extensions that needed ceiling installation. Joey made lots of wallet-friendly suggestions throughout his tour of the house that respected our old home's charm, and we could tell that he really knew housing thoroughly."

Energy Efficiency Auditing FAQs, answered by experts

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.
