Biofilm sludge jammed the condensate lift pump float sensor while a loose outdoor flare fitting lowered R410A operating pressure. Upon arrival in Subhanpura, Vadodara, our mobile engineering squad recorded baseline electrical amperage, voltage stability, manifold operating pressures, and airflow Delta-T before opening any enclosure or refrigeration joint.

2. Engineering Rectification Executed

Removed decorative grille, sanitized drain sump and lift-pump impeller, torqued flare nut, evacuated and weighed R410A in liquid phase, and verified balanced 4-way louver airflow with zero ceiling leakage.
