Rooftop HVAC equipment serviced by JJR Mechanical
Mechanical Service

Service, maintenance and energy work.

A full-service mechanical contractor for the New York and New Jersey area — repair, scheduled maintenance, and measures that bring operating cost down.

Service & maintenance

Repair and maintenance across the mechanical plant.

We service heating, cooling and ventilation equipment of most types and sizes. Our technicians are trained on current equipment and can advise on the right approach for installation, maintenance and repair of your specific system.

  • Rooftop units
  • Packaged units
  • Mini-split systems
  • VRF systems
  • Chillers
  • Ventilation systems
  • Ductwork & distribution
  • Air handlers
  • Same-day emergency service

    When a system goes down in a heat wave or a cold snap, response time is the whole service. We keep capacity for emergency calls.

  • Factory-trained and certified technicians

    Trained on the equipment we carry and on current HVAC technology — which matters most on control and communication faults.

  • Supplemental unit installation

    Adding capacity to a space the existing system was never sized for — server rooms, additions, converted space.
