"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."

"It went really well. They came in immediately and sealed off the basement from the rest of the house (There's no door to the basement)). They also set up very large and powerful hepa-air-cleaning units which they kept running through the whole job and in fact until the industrial hygienist returned for post-testing after the job was completed. The manager Mike assured me that the job would be done with the utmost effort and care and that's exactly what happened. The main workers, Marcello and Israel were terrific, meticulous, hard-working, reliable, responsive to any concerns I raised. I really couldn't have asked for any more. The post-test results showed Zero spores of the two bad molds with high readings in the pre-job testing. It's a really nice feeling when people come in and do the job just as they promised to."

"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!"

"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."

"A lot of folks say they donâ  t normally leave reviews and they do this time either out of extreme discomfort or appreciation. Iâ  ll join the band. My first review of all time. These folks not only did the job how it was meant to be, not how I asked for, but also came back at no cost for a correction at a very short notice and they aced it. They are a testament to Integrity; Doing the right thing even when no one is watching. After having two home gutted out and redone, I can say with confidence that they are by far the most professional company I worked with. Jacob handled and oversaw the project. Real difference lied with his personal touch. He is the best I could think of for the job. Make no mistake, if you think all this comes at a premium, it doesnâ  t. They also provided the best value on the continuum of delivery and cost, by a long shot. Do I recommend them? Hell yes. It will be the best decision youâ  d make if you need to improve insulation in your house. A special thanks goes to PS&G for vetting them as an approved contractor, which is how I got a hold of them in the first place."
