Read full description

CoolSync is the filter maintenance companion app for NJ Filters clients, giving building managers and technicians a live view of every air handler on site. TRACK EVERY FILTER CHANGE Log filter changes in seconds with the exact filter type, quantity, and timestamp. Every change is recorded against the specific air handler, so you always know what was serviced, when, and by whom — no more paper checklists or guesswork. KNOW YOUR AIR HANDLERS Browse a complete registry of your building's air handlers organized by area, with each unit's filter specifications at your fingertips. Technicians see exactly which filters a unit takes before they open the panel. STAY AHEAD OF INVENTORY Real-time stock levels update automatically as filters are used. Configurable minimum-level thresholds trigger in-app alerts before you run out, so reorders happen on time — without overstocking. MANAGE WORK ORDERS Create, track, and complete filter change work orders from the field. Built-in scheduling keeps changes on the optimal interval for air quality and HVAC efficiency. REPORTS ON DEMAND View Filter Activity and Inventory reports right in the app, or email a polished PDF to stakeholders with one tap — perfect for compliance records and management updates. BUILT FOR MULTIPLE BUILDINGS Manage a portfolio? Switch between your authorized buildings instantly. Each building's handlers, inventory, and work orders stay cleanly separated. SECURE ACCESS Sign in with Face ID or fingerprint. Role-based access ensures technicians and building managers each see what they need. CoolSync is available to NJ Filters clients.
