Commercial, Institutional & Multi-Family PM Programs

What’s Included in a JLL Preventive Maintenance Visit

No pencil-whipped checklists. We inspect your mechanical rooms, rooftops, and ductless zones like building engineers—catching biological growth, clogged drain pans, and safety hazards before they turn into emergency shutdowns.

Ductless, VRF & Air Handlers

  • Indoor Unit & IAQ Inspection: Front panels, filter frames, louvers, and internal blower wheels inspected for mold growth, dust buildup, odors, and pest intrusion
  • Condensate & Sludge Prevention: Drain pans, traps, and float switches inspected for sludge and debris to prevent ceiling and wall leaks
  • Air Handler & Filter Cataloging: Full dimension cataloging, commercial pleated filter replacement, belt tension checks, and blower bearing diagnostics
  • Evaporator & Condenser Coils: Accessible coil brush-cleaning, fin damage assessment, and chemical washing recommendations for heavily soiled VRF and split condensers
  • Refrigeration & Controls: Subcooling, superheat, compressor amp-draw, and controls verification

Heat Pumps, PTACs & Ventilation

  • Heat Pump & Rooftop Heating: VRF reversing valves, defrost boards, and RTU heat exchanger safety checks
  • Ventilation Systems: Exhaust and supply fans, motors, belts and sheaves, dampers, and airflow checks
  • PTAC & Console Units: Coils, blower wheels, fan motors, condensate drains, and controls inspected and cleaned
  • Water-Source Heat Pumps: Strainer and loop-water flow checks, coil and drain-pan cleaning, and fault diagnostics
Multi-Page PDF Deliverable Included

Executive Maintenance Reports Built for Boards & Property Managers

After every visit, your team receives a structured, multi-page PDF report ready to share directly with building ownership, school administrators, or condo boards:

1. Executive Summary & Rating

Overall "Condition Found" grading, numbered Key Findings on Page 1, and a clear breakdown of all work completed during the visit.

2. Before & After Photo Proof

Labeled photos of internal blower wheels, drain pans, evaporator coils, outdoor condensers, and control panels, showing exact room-by-room conditions.

3. Scope vs. Deep-Clean Quotes

Clear separation between routine filter/coil maintenance and separately quoted deep-cleaning (full unit disassembly, bib-kit pressure washing, or heavy chemical descaling).

4. Risk & Pre-Existing Audit

Flags urgent safety concerns (seized valves, standing water, fin damage, or abandoned controls) and coordinates follow-up repair phases.

Commercial Refrigeration

Walk-in coolers and freezers, ice machines, reach-in units, and condensers. We diagnose and repair the systems that keep restaurants, kitchens, delis, and retail cold storage running, including TXV replacement, compressor diagnostics, and refrigerant recovery. When a walk-in goes down, product loss starts immediately, so we prioritize refrigeration emergencies.

VRF & Mini-Split Systems

Installation, commissioning, and ongoing service for variable refrigerant flow systems from Mitsubishi, Daikin, LG, and Panasonic, from single-zone residential mini-splits to 20+ zone commercial VRF. We handle refrigerant line routing, electrical tie-in, controls commissioning, and the diagnostic work that keeps multi-zone systems running efficiently.

24/7 Emergency Service

Equipment fails at the worst possible times. We answer nights, weekends, and holidays across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island, and prioritize by what's actually at risk: refrigeration with product loss, heat in winter, cooling in a heat wave.

Local Law 97 Retrofit Work

We work alongside Professional Engineers and architects to plan and carry out the physical retrofit work that gets NYC buildings under their carbon emissions cap: heat pump conversions, refrigerant transitions, and equipment upgrades. JLL is part of the NYSERDA Clean Heat contractor network.
