How can I monitor rooftop HVAC units across 100 locations?

Nobody watches 400 rooftop units on a dashboard. What multi-site monitoring looks like when it is built around exceptions instead of screens: one connection per site, nightly scoring, and a short ranked list each morning.

How can I tell whether an RTU is losing refrigerant remotely?

Refrigerant loss leaves a signature in the data: shrinking temperature drop across the coil, stretching runtimes, stages working longer for the same result. What to watch for, and why thermostats stay quiet until it is an emergency.

How much does commercial HVAC monitoring cost per rooftop unit?

The three pricing shapes in the market, what each tier costs per unit, the hidden fees to check in any quote, and the ROI math against a single avoided emergency call.

Software-only vs hardware-bundled HVAC monitoring: which fits commercial buildings?

The two approaches compared on cost, installation, contracts, and depth. Which fits sites that already have controls, which fits sites with nothing, and when to combine them.

What is fault detection and diagnostics (FDD) for rooftop units? A plain-English guide

FDD finds developing HVAC problems in operating data before they become failures. What it is, what it catches, what it cannot do, and five questions for evaluating any FDD product.

How to monitor HVAC across all your locations without installing anything

Nobody knows how the whole fleet is doing right now. The four real options for fleet-wide visibility, what each actually costs, and why the data you need probably already exists.

The cheapest fix in HVAC, and why it almost never happens on time

Coil cleaning costs almost nothing. Ignored coils cost compressors. Why calendar-based maintenance gets this wrong, and what condition-based looks like instead.

Case study

Finding refrigerant leaks before they find your energy bill

A slow leak does not stop cooling. It just costs more every day. Nine days of warning before a technician found five separate leaks in one coil.

Case study

One location, three failing units, zero phone calls

A struggling compressor, a failed compressor, and blown fuses, all at one address, all invisible from inside the building. One screen turned three emergencies into one visit.

The failure timeline nobody sees

Every rooftop unit failure has two timelines: the day the store finally calls, and the day the unit actually started failing. The gap between them is where all the money is.

Case study

A failing kitchen unit, flagged five days before anyone noticed

Nobody at the store called it in. The platform had already flagged the unit, the operator scheduled the repair on their own timeline, and the health score proved the fix held.

See your fleet the way we see it

Every rooftop unit, every location, scored nightly. No new hardware.
