Your first alert that a system is failing shouldn't be an angry resident.
Vetralis mounts on the outdoor condenser and reads refrigerant pressure and line temperature continuously. It computes superheat and subcooling, learns what normal looks like for that specific unit, and alerts your maintenance team when a system drifts out of range — days or weeks before it quits. Every unit rolls up into one fleet view.
At portfolio scale, HVAC is not a comfort problem — it is a dispatch problem, a capital planning problem, and a resident retention problem. Vetralis moves the alert earlier, to the people who can act on it cheaply.
A no-cool call at 9 PM in August costs after-hours labor, a second truck roll for parts, and a concession to the resident. The same fault caught on a Tuesday morning is a scheduled visit.
Every alert carries the readings from the moment it tripped, plus the run history behind it. Your technician arrives already knowing what the system has been doing instead of re-measuring yesterday.
Between residents, a failing condenser has no one to report it. Offline and out-of-range detection means an empty house is still supervised — and still rent-ready on turn day.
Compressor decline and repeated out-of-range events are visible across the portfolio, so replacement budgets are built from equipment condition instead of age assumptions.
New equipment fails from commissioning faults — undercharge, a kinked line set, a metering device never set correctly. Those show up in superheat and subcooling immediately, while the labor warranty is still live.
Pricing scales with volume, deployment pattern and how your maintenance organization is structured, so the number you evaluate reflects your actual rollout rather than a published rate card.
Nothing to provision on site, nothing for a resident to set up, nothing to keep logged in.
Two pressure sensors go on the liquid- and vapor-side service ports a technician already uses. Two temperature probes strap onto the lines with a ratchet clamp. Nothing is cut and nothing is drilled. Opening the refrigerant circuit requires a certified technician, so this is never a DIY or maintenance-staff install.
Each monitor has its own cellular connection, with cellular service included for the lifetime of the unit. It never touches a resident's Wi-Fi, and there is no site gateway, hub or bridge to install, secure or maintain at the property.
Every monitor across every market appears in a single portfolio view with health at a glance. Your team sees the whole book; a regional manager sees their markets.
Out-of-range conditions reach your maintenance organization by text, email and in-app, with a morning digest listing only the units that need attention, most urgent first.
The same hardware serves the person planning capital, the person dispatching trucks, and the person standing in front of the unit.
Condition data across the book
Every monitored unit in one place, with health and open alerts at a glance across all markets.
Group units the way your organization is actually structured, so a regional lead sees their own book and nobody drowns in the national list.
Make, model and metering type held against each address, so the portfolio has an equipment inventory instead of a spreadsheet.
Units that keep drifting out of range surface as patterns, which is what turns a maintenance line item into a replacement decision.
If a monitor goes dark you are told. No silent blind spots where a unit is unsupervised and nobody knows.
Turn the emergency queue into a schedule
One morning email listing only the units needing attention, most urgent first. Each team member opts in individually.
A developing problem reaches dispatch while it is still schedulable, instead of arriving as an after-hours emergency.
Healthy, worth watching, and service recommended — so a dispatcher can triage a morning list without opening every unit.
An issue closes itself in the app once the next reading comes back healthy, so the queue reflects reality instead of accumulating stale warnings.
Invite staff with a join code, set roles, and choose exactly who receives which alerts and digests.
Arrive knowing, not guessing
Superheat and subcooling trends, high- and low-side pressures, line temperatures, runtime and condenser split — the working data, not a consumer summary.
Each alert carries the readings from the moment it tripped, so the diagnosis starts from data rather than from a description of the symptom.
A single most-likely root cause — low charge, restriction, airflow, condenser fouling — with recommended next steps, and an explicit statement when the read is uncertain.
Photograph the dataplate and the model and serial are read and filed against the unit. The indoor unit reveals the metering type.
What the system has been doing for days before the call, so a technician is not re-measuring yesterday to find out.
Real-time alerts run on a physics engine — pressure and temperature evaluated against the range that specific unit has established as normal, latched with hysteresis so it does not chatter. A second layer reads roughly ninety days of history with a language model to catch slow-developing problems that no instantaneous reading can see. We keep those separate on purpose, because they carry different confidence.
Evaluated continuously against the unit's own established operating range.
Reads roughly 90 days of history. Catches drift too gradual to trip an instantaneous threshold.
These are the conditions Vetralis is looking for. It is a monitoring product and cannot detect every possible fault — monitoring two refrigerant lines cannot assess a heat exchanger, electrical connections, condensate drainage, or airflow at the air handler.
An alert nobody trusts is worse than no alert at all. At portfolio scale a false-positive rate becomes a dispatch cost, so accuracy is the product.
Thresholds are set against the baseline that specific unit establishes in service, not against one-size-fits-all textbook numbers that fit no real installation.
Outdoor conditions are part of every evaluation, so a 105-degree afternoon that explains higher head pressure does not generate a truck roll.
Alarms use hysteresis and debounce, so a condition that hovers at the edge of a limit produces one alert rather than forty overnight.
The actual make, model and metering type inform the read, which sharpens the diagnosis on the units where it matters most.
An uncertain read is reported as uncertain. The technician view and the owner view always tell the same story, and neither one guesses.
Firmware improves in the field without a site visit, so a fleet installed this year benefits from next year's engineering.

Vetralis is a monitoring and alerting product. It is not a substitute for professional maintenance or inspection, and it cannot detect every possible fault in an HVAC system.
We would rather tell you what is coming than let you assume it is already here.
Pushing alerts straight into the system your team already dispatches from, rather than into an inbox. Tell us which platform you run and it informs the order we build.
A growing database of HVAC models with charging targets and specifications, for deterministic model-aware diagnostics.
A tracked performance trend per unit, to flag degradation as a number rather than an event.
Purpose-built thresholds for commercial refrigeration, where downtime spoils inventory rather than comfort.
Pricing depends on volume, deployment pattern and how your maintenance organization is structured, so it is quoted rather than published. Start with a pilot on one community, and we price the rollout against what that pilot actually shows you.
The way every portfolio should start.
For operators extending across markets after a pilot.
For developers fitting whole communities at once.
Per-unit pricing depends on volume and deployment pattern, so it is quoted rather than published. Installation is performed by a licensed technician and is quoted with the units.
Tell us roughly how many units you hold and how your maintenance organization is structured, and we will come back with a pilot scope and a per-unit number within one business day.
Talk about a pilotPortfolio enquiries reach us directly, not a queue. If you would rather send a specification request or a vendor onboarding pack first, that is fine too.
