ADE Systems

ADE Systems operates as a general contractor serving Freeport, New York, and surrounding communities in Nassau County. The business holds a 3.4-star rating derived from 19 customer reviews, with operating hours Monday through Friday from 8:30 AM to 5 PM. ADE functions primarily as a manufacturers' representative, distributing HVAC equipment to contractors, engineers, and architectural professionals across New York and New Jersey.

ADE Systems distinguishes itself as a premier representative for commercial HVAC equipment, offering air distribution products, fan applications, air handling units, fan coils, variable frequency drives, electric heating, and humidification systems. The company carries products from major manufacturers including Greenheck, serving the professional trade community rather than retail homeowners. Their website emphasizes technical expertise and product knowledge as the core competitive advantage.

Customer feedback presents a mixed picture of service quality. Several reviewers describe interactions with staff members as condescending, with one contractor reporting frustration when requesting a quote for Greenheck ERV parts. Another customer purchased 10 VFDs that experienced control board failures within one year, with the company refusing to provide replacement parts despite an advertised three-year warranty. A separate reviewer reported receiving a damaged fan with no refund or shipping compensation. In contrast, one reviewer described the team as knowledgeable, professional, and helpful.
