HVAC jobs it fits

ProtoPM runs jobs that last days to months and end in a commissioning and a handover. Office and crew work from the same project, from the load calculation to the final balance.

  • Furnace and air conditioner replacements
  • Heat pump installs, including the final inspection
  • New-build mechanical, as a sub to a general contractor
  • Ductwork modifications and retrofits
  • Commercial rooftop unit changeouts and tenant fit-outs

From load calculation to final balance

Pick HVAC as your company's trade and new projects start from a template you can edit. Furnace, air conditioner, heat pump and ductwork jobs each start from their own shorter list. The main HVAC template spreads these milestones across the job's dates:

  1. Load calculation.
  2. Equipment.
  3. Ductwork.
  4. Rough-in inspection.
  5. Start-up.
  6. Final balance.

In the field

  • Daily logs: crew count, work done, weather and delays for each day.
  • Inspections: rough-in and final come pre-filled on the HVAC template. Add the permit number, date and inspector, then mark each passed, failed or re-inspect.
  • Punch list at start-up: the template adds balance the system, set the thermostat, register the warranty and check the filters.
  • Files: keep the load calculation, equipment submittals, the permit and photos of the install from your phone with the job.

Money and change orders

  • Change log: record a different unit size, extra duct runs or a new line set found on site, with the cost and schedule impact, before you do the work.
  • Budget and actuals in Financials, hidden from the client.
  • Invoices: send progress and final invoices; invite the GC or owner as a read-only Viewer who can see them.
  • Risks: long-lead equipment such as rooftop units or chillers, tracked before it holds up the job.

How ProtoPM works

Free covers unlimited projects and people, your first company free (extra companies are an add-on), and 2 GB of storage per company (more is optional, from $5/mo per company). See every feature.

  1. Sign up and create a project. A title is enough.
  2. Financials: budget, actuals and invoices.
  3. Schedule and Field: dates, daily logs and punch items.
  4. Project Delivery: changes, risks and lessons learned.

Why teams pick ProtoPM

  • $0 Free plan with no end date. No credit card.
  • Sign up yourself. No demo call.
  • Plain tabs for schedule, field, costs and changes.
  • Projects and users are unlimited on Free; core modules never cost extra. Optional company add-ons start at $5 CAD/mo when you need extras like more storage or branded documents — nobody pays per user.

When another tool wins

If most of your work is service calls and maintenance agreements (dispatching techs, recurring tune-ups, quoting on site and taking card payment), a field-service tool such as ServiceTitan, Jobber or Housecall Pro fits better. ProtoPM is for project work. It doesn't do load-calculation software, estimating or dispatch, so keep those tools, and large firms that need ERP integrations or single sign-on fit enterprise suites.

How to start

  1. Sign up free, or start from the HVAC homepage.
  2. Set your company's trade to HVAC so new projects start from the HVAC template.
  3. Create the job (for example, a heat pump install) with dates and a budget.
  4. Invite your crew, and add the GC or owner as a read-only Viewer.
