Arrived onsite for no heat service call. Upon arrival found system disabled. Gas valve at the unit was turned off. Thermostat wire was disconnected. Molex plug to the control board was removed. Reassembled system and was able to get it to fire up. It took some time for the ignition control to start. This could be due to sitting for so long. Recommend updating ignition system. Spoke briefly with contractor for the building and explained my findings. Will provide estimate for repair or replacement of the system.
