HVAC maintenance reports your customers actually read

Checklist, pressures, temperatures and before-and-after photos, filled on the roof and sent as a clean PDF with your logo. Next spring, the unit’s last readings are already there.

What changes

Three things you stop doing

Readings scribbled on the back of an invoice

Supply and return temps, suction and discharge pressures, amps and static pressure each get a labeled field with units, so the report reads the same no matter which tech wrote it.

Maintenance agreements that renew themselves only on paper

Set agreements to two visits a year. The call list shows who is due for the spring or fall visit, with the contact’s number.

“What did you do last time?”

Open the address and see every unit, its refrigerant and filter size, and what was found on each visit, including findings you have not quoted yet.

Service due

The call list builds itself

Every customer on a cycle shows up before they are due, with the contact’s name and number. Call, book, mark it booked, and it leaves the list.

Rules & filing

What to know for hvac

Requirements vary by state, city and the code edition your authority having jurisdiction uses. This is a starting point, not legal advice.

  • Residential maintenance reports are mostly warranty and customer records, not a legal filing.
  • For commercial systems with 15 lb or more of HFC refrigerant, EPA rules require refrigerant service records; the report keeps refrigerant type and findings per unit to support that record.
Questions

HVAC contractors ask

Does it work alongside Jobber or Housecall Pro?

Yes. Keep scheduling and invoicing where they are. Use this for the report your customer gets and for the unit history at each address.

Can I add my own checklist items?

Yes. Switch off items your crew doesn’t do and add your own, for example economizer checks only for commercial RTUs.

Does it work on the roof with no signal?

The phone app keeps the draft as you type. Sending needs a connection; offline sync is on the roadmap for the native app.

What does it cost?

Free for 5 reports a month. Pro is $29 a month for unlimited reports and automatic reminder emails; Team is $69 a month for 3 field technicians. Every account gets 14 days of Pro starting with the first report, no card needed.
