About Long Island Mechanical
NYC-LI MECHANICAL LLC, doing business as Long Island Mechanical, was formed as a New York LLC on June 10, 2026. The filing was done personally by the owner or officer, listed as C/O BLUMENFELD DEVELOPMENT GROUP, LTD., who also serves as the registered agent. The company's principal address is in Syosset, New York. No annual report or EIN on file yet. The business operates in the commercial HVAC sector, a subcategory of HVAC services. Its website, built with Go Daddy Website Builder, describes over 30 years of experience, offers maintenance plans and emergency service, and mentions working with NYSERDA and Con Edison incentives, suggesting a well-established operation. The site is modern, uses HTTPS, and has a copyright year of 2025. We estimate revenue in the $1M-$10M range and a team of 6-25 employees, based on the comprehensive services and physical office indicated on the website. The footprint appears to be a single brick-and-mortar location in Massapequa Park, NY. The domain was registered on September 25, 2020, over five years before the LLC filing, which suggests the business was operating under a different legal structure or as a sole proprietorship before formalizing as an LLC. The company was first recorded here on June 12, 2026, just two days after filing. Two other entities share the same principal address, which may indicate a shared office or related businesses.
