At sunrise an HVAC engineer with a tool bag walks away along a long row of rooftop units on a large commercial roof, copper lines beside him and a city skyline far behind.

Maintenance Calendar · service agreements · call-outs

Every round on every roof, on one calendar.

Your service agreements set the rhythm: rooftop units quarterly, chillers monthly, the cooling tower through the season. Frigalto is built to turn each agreement into recurring maintenance rounds, building by building, keep every engineer’s day in view, and make room for the call-out that won’t wait.

One service agreement

A building’s agreement, set as the rounds it needs.

A commercial service agreement isn’t one visit on repeat. Each kind of plant on the building has its own rhythm, and each rhythm is a recurring series on the Maintenance Calendar — every round created up front, each with its own record.

  1. Open the agreementAshcombe Tower, on the service agreement with Ashcombe Property Group. Nothing scheduled yet.
  2. Rooftop units: quarterlyThe east roof’s four rooftop units, one round every three months, starting Wednesday, January 14.
  3. Chillers: monthlyThe two chillers in plant room B1, a round every month, all year.
  4. Cooling tower: monthly, in seasonFrom the spring start-up to the end of October — the series ends on whatever date you mark as the close of the cooling season.
  5. Air handling units: every two monthsFilters, belts and coils on the four AHUs, every second month.
  6. Your client hears when a round is bookedThe facilities team gets the booking email in your company’s name — the round, the day and the time.

Your month

Six clients, one October — and the week the heating comes on.

Every agreement lands on the same Maintenance Calendar: the tower’s quarterly round, the hospital’s weekly visits, the data center every two weeks, the supermarket stores one by one. In October the changeover week sits across it all.

The call-out

2:40 on a hot afternoon. A dairy case is warming up.

Marlow Market’s Elm Street store calls: the condensing unit behind the dairy case has tripped. The call-out goes in as a one-off task, takes its place in S. Brennan’s afternoon — and the coil quote visit that can wait moves to Thursday.

  • A call-out is a one-off task: client, building, unit, time and engineer.
  • Drag a one-off visit to another day; the recurring rounds keep their rhythm.
  • Times in quarter hours, from 7 AM to 6 PM.

Seasonal changeovers

Start-up in spring. Changeover in the fall. Both on the calendar.

The two busiest stretches of the year are series too: you set what each changeover covers and the dates it runs, building by building, and the rounds appear where they belong.

  • Cooling-season start-up

    The weeks before the first hot day: towers back in service, chillers started, rooftop units checked in cooling.

  • Heating changeover

    Before the first cold morning: heating sections checked, heat pumps switched over, towers drained down where the winters freeze.

An HVAC engineer leans into the open access door of a rooftop cooling tower, checking inside, with office towers behind under a bright sky.

The seasons are yours: a client in the southern hemisphere runs them the other way round, and the dates on the calendar are the ones you set.

Recurring rounds

Set the rhythm once. Every round is its own record.

The scheduling underneath a service agreement — the same engine for every building you look after.

    A rhythm for each kind of plant

Questions

About the Maintenance Calendar

Can I give each kind of plant in a building its own frequency?

Yes. Each frequency is its own recurring series — rooftop units quarterly, chillers monthly, the cooling tower in season — all on the same building and the same service agreement.

Can a series stop at the end of the cooling season?

Yes. A series ends after a number of rounds or on a date you choose, so a cooling tower series can finish on the day you pick as the season’s close.

What happens when my client cancels a round?

Cancel that round with a reason and your client gets the cancellation email; the rest of the series stays booked. To end a series early, stop the rounds still to come — completed, invoiced or paid rounds don’t change.

Does Frigalto plan routes between buildings?

No. The calendar shows each engineer’s day in time order; it doesn’t optimize routes or reorder visits for you.

What do my client’s emails say?

Booked, started, completed and canceled — each in your company’s name. The completed email says the round is complete and the invoice follows; findings and records go in the reports you choose to send.

Is the Maintenance Calendar available today?

Frigalto is launching soon. What you see on this page is how it is built to work at launch; every scene is illustrative, built on invented clients and sample data.
