Get matched with top energy efficiency auditors in Commack, NY

"Frank is extremely professional and offers expert service. He is prompt in returning phone calls and he is available by phone and text. His prices are excellent. I highly recommend FLG Performance to service your furnace."

"Ultimate pros. Extremely efficient and knowledgeable. Called for a quote for insulation and received an education on all aspects of my attic. Brian performed a complete in house audit of my energy systems while he was here. Just wish I was in a financial position to hire a top shelf professional organization such as theirs. My loss."

"Very professional and Helpful. Gave me great things to start with and a ton of information. Would highly recommend"

I conduct energy audit tests for homes, whether they are colonial or brand new construction. I can recommend you various forms of weathersealant, thermal wrappings, and storm window techniques, saving you thousands in the form of long-term heat insulation tech-forward solutions.

"Everything went smooth - a lot smoother than I thought! They were in and out very quickly. They were one of the only companies where the owner was there from the estimate to the installation."

"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!"

"Joey could not be better to work with. Prompt responses, on time (early actually) day of the job and completed in less time than anticipated. Walked me through every step of the process, why he was doing what he was doing, and stands behind his work. He and his crew are clean and restored everything back to it's original spot when completed."

"The customer service and work done was great, they came quickly assessed what work needed to be done, gave me an estimate that was very close to final price and a reasonable price at that. I’ve had to call plumbers in the past and they’ve left my place a mess, but these guys cleaned up way more than I expected. I was in complete panic before calling and they were extremely helpful and made the process an ease. I would definitely call them again if I need the services."
