About All Island Mechanical
All Island Mechanical holds a 4.7-star rating across 25 verified reviews, establishing solid credibility in the Setauket- East Setauket market. This HVAC contractor serves residential clients throughout the area, handling heating and cooling installations, repairs, and maintenance. The company operates Monday through Friday from 8 AM to 4:30 PM, providing scheduled service appointments for standard HVAC needs.
Without access to the company website, specific brand partnerships or specialized certifications cannot be verified. The available customer feedback consistently references heating system and air conditioning installations, suggesting a broad focus on residential HVAC replacement rather than niche specialty services.
Multiple reviewers describe specific scenarios that demonstrate the company's approach to service. One homeowner recounting a frozen pipe emergency notes that Jeff answered the initial call and assured help was available, while technician Rob arrived and provided professional, understanding assistance. Another client describes hiring Jeff and his son Brandon for an oil furnace installation, noting the pricing was fair compared to other company quotes. A third reviewer mentions the team installed a new HVAC system and replaced a heating unit, describing the technicians as always available by phone for follow-up questions.
