Quark LA HVAC & Electrical

Quark LA HVAC & Electrical was formed as a California corporation on May 29, 2026, filed personally by owner Qing Yan, who also serves as the registered agent. The company is based in Diamond Bar, California, and operates as an HVAC and electrical contractor. Its website, registered eight months before the filing (September 2025) via Gandi SAS, suggests a planned launch. The site is a modern, single-page WordPress site with a 2025 copyright and comprehensive descriptions of electrical and mechanical contracting services for industrial and utility clients, indicating an established operation despite being newly filed. No annual report or EIN on file yet. We estimate revenue between $100K and $1M, with 1 to 5 employees, and a brick-and-mortar footprint typical of a small contractor requiring a physical workshop or office. The domain was registered 254 days before the filing, and the site was built with a modern JavaScript framework, giving the business a polished online presence. Notably, the owner filed personally rather than through a formation service, and the domain registration predates the corporate filing by over eight months, suggesting advance planning. The website matches the business name and confirms an HVAC license in nearby West Covina, California.
