Synhelm for HVAC contractors

Installs, service calls, and the paperwork in between.

HVAC shops juggle installs that run for days and service calls that run for an hour. Synhelm's schedule, time clock, and job paper keep both kinds of work straight.

Free for up to 5 crew · no card to start · one price per shop

What gets in the way

The paperwork HVAC contractors shouldn’t be doing by hand.

  • Who's on which install this week?

    Drag people onto jobs by day; each tech sees their own week on their phone.

  • Mechanical drawings emailed around in five versions.

    The blueprint reader keeps one current set per job, with older revisions a tap away.

  • Quotes that don't look like the company you are.

    Estimates and invoices carry your logo and colour, with deposits and discounts built in.

The tools you’ll use

Everything on the job, nothing you don’t need.

  • Weekly crew schedule

    Put people on jobs day by day, drag to change, and copy last week in one click. Each person sees their own days on their phone.

  • Crew time clock

    Crew clock in and out of a job from their own phone with a PIN — no app store, no email accounts. Switch jobs and take breaks in a tap.

  • Blueprint reader

    Upload the PDF set and every page becomes a sheet to zoom and flip. Compare revisions, and mark up a copy to save, post in the job chat, or email.

  • Estimates that win work

    Your logo and colour on clean paper, with deposits, discounts, and tax. Email the PDF from the app; replies come back to you.

  • Invoices and reminders

    Turn the estimate into the job and the job into the invoice without retyping a line. Record partial payments and see what's owed.

  • Job photos

    Photos land on the job, not in someone's camera roll. Mark them up on upload; they shrink on the phone so they send on a weak signal.

  • Job costing

    Pro

    Labour at each person's rate plus expenses against the price, so you see the margin on every job while it's running.

  • Job chat

    Every job has its own conversation with the crew on it, so the office and the field talk about the same thing.

Questions

Asked by HVAC contractors

More in the full FAQ.

Can techs see their schedule on their phone?
Yes. Each person sees the days and jobs you've put them on. On Pro, they also get a phone notification when it changes.
Do my crew need to download an app?
No. They open one link or scan your QR code on any phone and sign in with a PIN. You can add it to their home screen so it opens like an app.
