Commercial HVAC & Building Performance

Stop the 2 A.M. Emergency Callout

A clogged filter or slipping fan belt turns into a costly emergency call and an angry client. MaxLinc watches compressor current, differential pressure and supply temps 24/7, firing instant SMS, voice and email alerts the moment a unit drifts out of range. Non-invasive retrofit, no monthly fee on WiFi.

Protect My Uptime

Priority One Feature

Predictive Maintenance.
Stop Catastrophic Failures.

Facility managers are exhausted by sudden breakdowns. The system utilizes CT clamps and pressure sensors combined with baseline algorithms to detect gradual drifting--alerting maintenance that a fan belt or compressor is failing weeks before the system actually dies.

Reactive

Fix it when it breaks. High cost, high downtime, catastrophic failures.

Preventive

Fix it on a schedule. Wasted parts, unnecessary labor, but fewer surprises.

Predictive

Fix it right before it breaks. Lowest cost, zero unplanned downtime.

Current Drift Detection

Predict motor wear via amperage creep.

Differential Pressure

Automate filter replacement schedules.

Non-Invasive Install

Clamps install without electrical shutdowns.

Equipment health score

The Equipment Health Indicator

Instead of drowning in raw data points, each asset gets a single 0-100% Health Score: green from 80%, amber from 50 to 79%, red below 50%.

✓Four factors: Sensors reporting, calibration drift, maintenance on schedule and service history.
✓Updated daily: The score is recalculated every day and on demand.
✓Maintenance reminders: Sent 7, 3 and 1 days before a scheduled task. A low score shows on the dashboard; no work orders are created automatically.

Frequently Asked Questions

How does monitoring catch HVAC failures before they cause downtime?+

MaxLinc sensors continuously log readings like compressor current, differential pressure across filters and coils, and supply/return temperatures. When a value drifts past a threshold you set, the cloud sends a real-time alert by SMS, voice call, push or email so a technician can act on a clogging filter or a slipping fan belt before it becomes an emergency service call.

Can I install these sensors without shutting down the equipment or cutting into pipes?+

Yes. Current monitoring uses a split-core CT clamp that snaps around an existing conductor with no rewiring, and differential-pressure sensors tap standard duct or filter-housing ports. Most zones can be instrumented without taking the unit offline, which makes them practical to retrofit across an existing portfolio of rooftop units, AHUs and chillers.

What temperature range do the probes cover for chilled-water loops and air handlers?+

The thermistor probes read the full HVAC working range, from chilled-water and refrigeration temperatures well below 0 C (32 F) up to hot supply air and condenser readings. Values are shown in both Celsius and Fahrenheit, and you set independent high and low alarm points for each sensor.

Is there a monthly subscription or per-sensor cloud fee?+

Not on WiFi. The BLOCK and EDGE devices on this page connect over WiFi and report to the MaxLinc cloud. Each device includes its first year of Premium; after that the free Standard tier keeps live data, every alarm and 45 days of history, and Premium (advanced reports, full history and sharing with new people) is optional at about $17.78/year (about $1.48/month), billed annually. Email and push alerts are free; texts and calls draw on a ~$3.70 alert credit included with each device.

How fast will I know when a unit goes out of range?+

Data is logged continuously, and alerting is real-time: the moment a reading crosses your threshold, the alarm fires through your chosen channels, including an automated voice call for critical events like a chiller fault or a server-room over-temperature, so the right person is reached even after hours.
