All State Air Control

All State Air Control has earned a 4.9-star rating across 87 verified client reviews, establishing themselves as Mount Vernon's most trusted heating and cooling specialist. Operating from Westchester County, the company maintains standard weekday hours from 8 AM to 5 PM, closing on weekends to focus on scheduled service calls. Their client base spans both residential homeowners and commercial operations including Curry Automotive, a local auto shop that relies on All State for equipment reliability. The team serves the greater Mount Vernon area and surrounding Westchester communities, handling everything from emergency repairs to new system installations.

The company differentiates itself through its maintenance contract program, offering seasonal check-ins and priority scheduling for signed clients. Homeowners consistently praise the team's responsiveness and straightforward communication, technicians explain repair options clearly before work begins, and service fees are described as reasonable across multiple reviews. This combination of proactive service agreements and transparent pricing builds long-term client relationships, with one reviewer noting a 13-year history with the company.

Customer stories reveal technicians who go the extra mile during challenging conditions. When Wil Pollock's dual aging systems failed during peak summer heat, Russ and his crew arrived at sunrise and worked continuously until sunset, without complaint, to complete the replacement in a single day. Winston has become a trusted name for routine maintenance, with multiple reviewers specifically citing his thoroughness and willingness to answer technical questions. Patrick's diagnostic skill at Curry Automotive demonstrated the team's ability to quickly identify root causes, saving the business from unnecessary repairs.
