The Problem

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.

Equipment failures go undetected overnight A rooftop unit that locks out at 10 PM isn’t discovered until the building opens the next morning — costing hours of uncontrolled temperature exposure and an emergency service call.
BAS infrastructure is too expensive for most buildings Full building automation deployments can run $30,000 to $100,000+ per building — requiring proprietary hardware, licensed controllers, and integrators who bill accordingly.
Multi-site portfolio management has no unified view Managing HVAC across multiple buildings with different systems, different BAS platforms, and different service contractors means no single picture of what’s actually running across the portfolio.
Outdated alarm dialers offer no real-time data Legacy alarm panels call a phone number when something trips — but provide no continuous monitoring, no historical trending, and no visibility into what was happening before the alarm.
Traditional BAS Monitoring — Typical Costs
BAS hardware per building $30,000 – $100,000+
Proprietary BAS integrator Required
BAS programming / commissioning $10,000 – $40,000
Annual software licensing $2,000 – $12,000/yr
Building network integration Required
Legacy alarm dialer systems Alarms only, no data
Real-time analog trending Requires full BAS
Deployment time Weeks to months
The Solution

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.

Signal Compatibility

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.

Typical Deployment

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.

Every additional building deploys the same way. All equipment across every facility appears in one unified dashboard — no additional software required.
Operational Benefits

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.

Detect Failures Immediately
Compressor lockouts, pump trips, boiler faults — AccuDose sends alarms the moment equipment goes down, not hours later when someone notices the building is uncomfortable.
Reduce Emergency Service Calls
Catching failures at 2 AM instead of 8 AM means a scheduled morning response instead of an emergency dispatch — reducing after-hours labor costs significantly.
Improve Preventive Maintenance
Historical trending across temperature, pressure, and runtime reveals gradual equipment degradation before it becomes a failure — enabling planned maintenance instead of reactive repair.
One Dashboard Across All Buildings
Facility managers and mechanical contractors get real-time status for every building in the portfolio from a single cloud dashboard — without logging into multiple systems or making site visits.
Reduce Equipment Downtime
Faster fault detection means faster technician dispatch — reducing the window between equipment failure and restored operation from hours to minutes.
No BAS Infrastructure Required
AccuDose delivers real-time HVAC monitoring without building network integration, proprietary controllers, or licensed integrators — at a fraction of what full BAS deployment would cost.
