FAQ
Questions We Hear Every Day
Honest, engineer-level answers — no sales fluff.
A VRF system in commercial use should receive professional maintenance at least twice a year — once before peak cooling season and once before heating season. A thorough visit covers coil cleaning on all indoor and outdoor units, filter replacement, refrigerant pressure checks, inverter board diagnostics, drain pan inspection, and a review of error codes logged since the last service. Neglected coils can reduce efficiency 15–25% within a single season.
The most frequent VRF repair calls involve inverter board failures, thermistor faults, refrigerant leaks at flare fittings, clogged drain pans on ceiling-cassette indoor units, and blocked outdoor unit fan motors. Error codes on Daikin and Mitsubishi VRF systems are specific enough that a trained technician can often diagnose the issue before opening the unit. Branch controller circuit boards also fail in aging systems and are worth checking during any major repair visit.
Yes. Micro-leaks at flare connections — particularly in high-vibration rooftop or mechanical-room installations — allow refrigerant to escape slowly over months. A VRF system running low on charge shows symptoms like reduced cooling capacity, longer run times, higher superheat readings, and eventually high-pressure lockout faults. Technicians check static and operating pressures against manufacturer tables and perform nitrogen pressure tests to confirm leak-free piping before recharging.
In most NYC co-ops and condos, the outdoor unit and shared refrigerant piping are the building's responsibility, while each shareholder or unit owner maintains their own indoor cassette or fan coil. House rules often require board approval before any VRF repair involving roof penetrations or riser access. Some buildings negotiate a single service contract for all indoor units to ensure consistent maintenance and coordinated refrigerant tracking.
Adding zones is possible if the existing VRF outdoor unit has spare capacity — most systems are designed with 10–30% expansion headroom. A technician verifies the outdoor unit's rated capacity versus current connected load, then sizes the new branch controller ports and piping runs accordingly. If the outdoor unit is already at or near its rated tonnage, adding a tandem module (where the manufacturer supports it) is more practical than full replacement.
