Louis, his son , Vinny, and the crew completely transformed the house in just 1.5 days--insulating everything from the walls to the rim joists and crawl space. Louis came by to look at my house, used thermal imaging and brought pictures to show me what to expect. Very thorough, knowledgable, trustworthy and truly helpful. Honestly, I was a little anxious about them drilling into the mortar of our brick exterior, but decided to trust the process. Their work is seamless. I can't even see where the holes were! They left the house spotless, can't even tell they were here. We felt the comfort levels improve immediately. Highly recommend this team if you want honest, expert work from people who actually respect your home and know what they're doing!

They sealed all the high hats and breaches. They filled it with blown cellulose to R49. Which has settled now after a few months. Not the R49. They came back 5 times to redo items that were not properly done. The AC problem is not what we were hoping for. Better somewhat. They recommended a larger fan to exhaust bathroom moisture. Not resolved. We spent over 15g . Not really happy with the outcome. We will have to hire an engineering company to access whatever is necessary to fix this problem.

He thoroughly explained how they would be taking care of my crawl space and cantilever insulation issues. The project was done in one day just before thanksgiving of 2023. The work crew was terrific along with the project manager Mike. There was one small glitch and Mike came back with another worker and took care of my concerns. I can't say enough as far as how satisfied we are. I delayed on writing this post until after this recent very cold snap ( wind chills to below10 degrees )to be sure that my heating issues were abated. They know what they are doing and never cut corners at all. They also exceeded my expectations!

Everything was about, "you've got to sign by tomorrow or you'll lose this great price". It wasn't a great price. According to him It was supposed to cost $6800 but if I had less than a certain income then it miraculously dropped to $3500 to do various insulations around the house, about half a day's work. The way the proposal was written it sounded very involved, but it was essentially insulating the attic and caulking around the house. That's a ton of money for that work. He then called me constantly, pushing for me to sign. When I finally told him I don't react well to these kind of deadlines he said "have a nice day" and hung up. This company is preying on people who don't know pricing and fall for their sales pitch.

After talking to a number of companies, I contacted our real estate agent from 18 years ago, Jeremy…read moreZucker. He recommended Long Island power solutions and my representative the wonderful David Kowalsky. One of the scam companies I had spoken with and never signed a contract nor indicated I wanted to move forward - after almost a year- out of nowhere, applied for a permit to put solar panels on our house. We live in Yonkers. I was horrified! I had no communication with them and they did this behind my back. It took a couple of months to straighten this out because a fine had to be paid by them to remove the permit. We first needed to put a new roof on before putting solar. It was such a scam and the company was located actually out west. That's when I called my real estate agent Jeremy and asked for his advice because he went solar and was extremely happy, and he had done all of the research. We took Jeremy's advice and we are thrilled! From the very beginning, it was a pleasure working with David Kowalsky. Not pushy. Very easy to reach at any time. He answered all of our questions, very straightforward and was always there for us. He searched around to find the best financing and any of the New York incentives. We first had to get a new roof on our 100 year old house. Once we got our new roof, we moved forward with Long Island power solutions. Everything went smoothly with them and they made the process actually enjoyable. Once they came out to install the panels on our 100-year-old colonial house, we didn't even know what they were here. It was very smooth, and they finished perfectly within the day and put up protection against the squirrels and raccoons of which we have a lot. I was afraid of them getting on the roof and destroying things. Where we live, we have a lot of wildlife. When they finished that day, they left our yard cleaner than when they arrived. We went online finally last September. We have the Ephase app on our phones and enjoy enormously, seeing minute by minute how much power we are drawing in from the sun. We even get power on cloudy days. Like everyone around the New York City and Westchester area, we have been stuck with consolidated Edison, which is a monopoly and for profit. Our bills have been jumping sky high and ConEd has been pocketing huge profit from everyone in this area that are stuck with them. We are so happy to have solar! We have only great things to say about this solar company. We have only had excellent interaction with them and the panels are working great and our representative David Kowalsky is always there for any questions that we have. Highly recommend!

LIPS had already obtained permits for project. When I notified Charles, he suggested that perhaps I leave remainder of my first payment (deposit) with them and we could try to spec out a system on the home we moved to. We are doing reno's to the home we moved to and decided not to move forward with solar. I let Charles know and asked if we could get balance of our deposit back (of course net of any expenses LIPS had incurred). Charles said he would see what he could do and ultimately passed the ball to the owner Joe, saying he was "just a salesman" and could not do anything else. I left messages/emails for Joe, but he didn't respond to a single message. If he responded and said no that my agreement didn't provide for any return of monies, I would have understood. (maybe not agreed but understood). But to ignore messages/emails from a client, does not seem right.
