HVAC in the field

Where answers come from

Four things feed an HVAC answer

Nothing here is a generic model database. Every source is either your record or a document you put in the workspace.

🧾
Your job history
Every completed call, the tech’s notes, the fault found and the fix — searchable by address, customer or model.
🏷️
Your equipment records
Installed units synced from your FSM, with serials, install dates and the plans attached to them.
📕
Manufacturer manuals
Install manuals and product data for the models we see in your records, plus anything you upload yourself.
🧮
Built-in calculators
Superheat, subcooling and airflow, run inside the chat so the tech does not switch apps mid-diagnosis.

What FieldIQ will not do

FieldIQ does not ship licensed code books. There is no bundled copy of the IMC, the IFGC or your state amendments — if your crew needs those searchable, upload your own copies and FieldIQ will index them. It also does not decide whether a repair is safe or correct. It shows the specification and the page it came from, and the technician verifies against the equipment in front of them before doing the work.
