Remote Monitoring for
Commercial HVAC
Infrastructure
Facility managers and mechanical contractors are replacing expensive building automation systems and outdated alarm panels with AccuDose — getting real-time visibility across rooftop units, cooling towers, boilers, chillers, and mechanical rooms without the BAS overhead.
HVAC failures go unnoticed until tenants call
Commercial HVAC equipment fails constantly — compressors lock out, cooling towers lose flow, boilers drop pressure, hydronic pumps trip offline. In most facilities, these failures aren’t caught by a monitoring system. They’re caught when someone complains it’s too hot, too cold, or the space is flooding.
Building automation systems exist to solve this, but they’re expensive to install, require proprietary controllers and licensed integrators, and are built for large facilities with dedicated building engineers. Smaller commercial buildings, multi-site portfolios, and mechanical contractors are left with standalone alarm dialers or no monitoring at all.
The result is reactive maintenance — dispatching technicians to investigate complaints instead of responding to real-time data.
Real-time HVAC monitoring.
No BAS required.
AccuDose delivers continuous monitoring for commercial HVAC infrastructure using built-in LTE-M cellular — no building network integration, no BAS programming, no proprietary controllers or licensed integrators required.
Mount AccuDose inside an existing HVAC control panel, wire it to temperature sensors, pressure transmitters, compressor run contacts, and equipment alarm outputs, and you’re transmitting live data to the cloud within the hour. Equipment faults, temperature excursions, and pressure alarms go out immediately by SMS and email.
Facility managers and mechanical contractors get real-time visibility across every piece of mechanical equipment — across one building or across an entire portfolio — without touching the building network or engaging a BAS integrator.
Every mechanical system.
AccuDose monitors them all.
From rooftop units to chiller plants, AccuDose delivers real-time data and alarm coverage across commercial HVAC and mechanical infrastructure — without BAS infrastructure or programming.
If your equipment
outputs it, AccuDose monitors it
AccuDose connects directly to standard HVAC sensor outputs and equipment control signals — the same signals already present in any commercial mechanical system.
Analog inputs accept 4–20mA signals from temperature transmitters, pressure transducers, flow meters, and level sensors. Digital inputs connect to dry contact outputs from equipment run confirmation relays, fault outputs, and alarm panels.
No protocol conversion, no gateway programming, no BAS middleware. If the signal is at the terminal strip, AccuDose can monitor it.
Up and running
in hours, not weeks
AccuDose mounts inside an existing HVAC control panel or electrical enclosure. No new field devices, no additional wiring infrastructure, no BAS programmer on-site.
Connect AccuDose to the sensor outputs and equipment signals that already exist inside the panel — temperature transmitters, pressure transducers, compressor run contacts, alarm dry contacts — power it on, and it connects to the cellular network automatically.
Facility managers can begin monitoring equipment from the cloud dashboard within the same visit. When something faults, the alarm reaches them by SMS or email immediately — not the next morning when someone walks in and notices it’s hot.
Less downtime.
Fewer emergency calls.
Real-time HVAC monitoring shifts maintenance from reactive to proactive — catching equipment issues the moment they occur, before they escalate into tenant complaints, emergency service calls, or equipment damage.
