About Jay's Heating and Air
Jay's Heating and Air has kept Yonkers comfortable for more than two decades, building a reputation on reliable installations, honest diagnostics, and responsive service across Westchester County. The company holds current licensing and maintains full insurance coverage, with 63 verified customer reviews averaging a 4.7-star rating reflecting consistent quality work. Owner Jay and his team operate from 23 Chestnut Street in downtown Yonkers and extend service to neighboring communities including Bronxville, Scarsdale, and Tuckaho.
What sets this contractor apart is their around-the-clock emergency availability paired with a genuine focus on energy-efficient system design. Unlike large franchises that push replacement, Jay's team regularly repairs existing equipment by sourcing hard-to-find parts, saving homeowners the full cost of a new installation. Their residential services cover thermostat upgrades, central air installations, and ductwork modifications, while commercial capabilities include rooftop units and high-capacity ventilation systems for larger properties.
Customer stories reveal the personal attention that drives referrals. When Keith DeFino's furnace failed with a newborn at home during a February cold snap, Jay arrived by 7:30 the next morning and worked nearly 14 consecutive hours to restore heat rather than leave the family waiting. Months later, Jay still calls to check in on the system's performance. Another reviewer noted Jay personally answered the phone on a weekend and provided fair pricing without upselling unnecessary repairs. These scenarios illustrate why the company has surpassed 1,000 satisfied clients over 22 years of operation.
What Customers Say
Five of five sampled reviews award 5 stars, with three explicitly praising owner Jay for answering calls directly and working through weather emergencies. Two reviewers highlight same-day or next-morning response times during heating breakdowns, and one mentions fair pricing as a differentiator from competitors.
