Stop VRF Failures Before They Start.
Active Monitoring watches your building’s VRF equipment in real time, so our team sees trouble before your tenants do — and we dispatch before it becomes a shutdown.

Most VRF failures are not sudden. They’re scheduled.
Manhattan’s commercial VRF boom ran from roughly 2012 through 2017, which means thousands of systems are now eight to twelve years old — the window where compressors, inverter boards, and refrigerant joints start to go. Rooftop exposure, thermal cycling, and the fact that VRF compressors run in both heating and cooling modes all accelerate wear.
The problem is not that these failures are unpredictable. The problem is that no one is looking until the call comes in. By then it is already an emergency repair, and you are paying a multiple of what planned intervention would have cost.
There is a second reason this matters now: Local Law 97. A VRF system running at degraded efficiency is a system running over its emissions limit, and NYC charges $268 per metric ton of CO2 over the limit — every year, forever. Proactive monitoring protects your building’s LL97 compliance numbers, not just its comfort.
“All of this could be avoided if they would take into consideration basic connectivity, such as a Hero system to monitor problems before they become a problem. Something that is proactive instead of reactive.”

What we actually watch for.
Active Monitoring is not a dashboard we hand you and walk away from. It is our team — not yours — keeping a continuous eye on the operating signals your VRF system already produces, and responding when those signals say something is wrong.
What we monitor:
- Fault and error codes across all indoor and outdoor units
- Compressor operating conditions, amperage, and modulation behavior
- Refrigerant circuit pressures and temperatures
- Condenser head pressure and discharge temperature trends
- Branch selector valve state on heat recovery systems
- Communication health between outdoor units, branch controllers, and indoor heads
- Zone-by-zone comfort performance against setpoint
- Airflow and filter status where sensors report it
We work with whatever connectivity your VRF system already has — the manufacturer’s own cloud platform (Daikin Hero Cloud Services for Daikin VRV systems, and the equivalent for other brands), an existing building management system, or a dedicated gateway we install during the baseline assessment.
If a code pops up between monitoring checks, you can also look it up yourself on our free VRF error code tool.
Four steps from install to peace of mind.
1. Baseline assessment.
Our team walks your building, inventories the VRF equipment, and confirms what is already connected and what is not. You get a plain-English report of the system’s current state and what it would take to bring it under Active Monitoring.
2. Secure connection.
We connect your VRF equipment to our monitoring workflow — through the manufacturer’s own cloud service, your existing BMS, or a dedicated gateway we install. No new app for your team to learn. No dashboard you are responsible for watching.
3. Continuous watch and triage.
Your system’s operating data flows to our team. We filter the noise from the signal — a routine code clearing itself in 30 seconds is not an alarm. A pattern of rising discharge temperatures on a compressor that is about to fail is.
4. Proactive dispatch.
When we see a real problem, we call you — not the other way around. We schedule the technician, coordinate building access, and resolve it on our terms, not during an emergency after hours.
Why this only works with a real VRF specialist.
Mountain Mechanical services hundreds of VRF systems every year across Manhattan and the NYC metro — enough volume to see failure patterns most contractors only read about.
Factory-certified across every major VRF brand.
Mountain Mechanical is factory-certified on Daikin, Mitsubishi, LG, Fujitsu, and Samsung. Buildings running mixed manufacturers get one team, one point of contact, one accountable owner — instead of juggling five different service relationships.
Built for Manhattan, not the suburbs.
We know the realities of NYC commercial work: freight elevator windows, tenant coordination, after-hours access, Local Law 97 pressure on older equipment. Monitoring only pays off if we can actually respond inside this environment, and that is what MM does every day.
You will always deal with an owner.
Peter Montana has been in HVAC for more than 35 years and personally oversees MM’s VRF service relationships. When something on your building needs a judgment call, it is not routed through a call center — it comes to someone who owns the outcome.
Is Active Monitoring a fit for your building?
Active Monitoring is designed for commercial buildings in the 10,000 to 500,000 square foot range with existing VRF equipment — especially systems installed during Manhattan’s 2012–2017 VRF boom that are now eight or more years into their service life. Common fits include hotels, luxury condos, mixed-use buildings, boutique offices, houses of worship, retail, and high-rise commercial properties.
If your building already has a scheduled service contract and you want proactive coverage between those visits — or if you do not yet have a service contract and want a better first step than waiting for the first failure — this is for you.
Tell us about your building.
We will follow up within one business day with next steps for a baseline assessment. No obligation, no hard sell — just a conversation with someone who understands your equipment.
