Job Description

Build on a 65+ year legacy in Yonkers, NY

Step into a third-generation, family-run team that’s been trusted since 1959. As our HVAC Service Diagnostics Technician, you’ll keep homes and light commercial spaces comfortable and efficient by maintaining, troubleshooting, and repairing a wide range of systems.

A day in the life

You start your day in Yonkers, NY, reviewing your service queue. First stop: a split system needing seasonal maintenance. Next, a light commercial rooftop unit that’s short-cycling. You read and interpret wiring diagrams, trace controls, and walk clients through what you’re seeing—clear, courteous, and solution-focused. Between calls, you log notes with precision to maximize productivity and minimize downtime. When needed, you’re comfortable on a 40-foot ladder or navigating a confined space to get the job done. Some days include after-hours on-call rotation to keep customers up and running.
