Fieldkiln is being built with the first HVAC field technicians. Join the waitlist and help shape what ships first.

Built for the moment you're stuck on-site

Not a filing cabinet of PDFs. A search bar that gets you to the exact step you need, fast, while the customer is still standing there.

Search by equipment or symptom

Type a model number, an error code, or plain language like "won't start after capacitor replacement." Fieldkiln matches it to the exact manufacturer procedure, not a general troubleshooting article.

No monthly cap

Bluon3 manuals / mo
FieldkilnEvery brand, no cap

Bluon caps free access and paywalls the rest. Fieldkiln doesn't ration your library.

Offline brand packs

Download Carrier, Trane, Lennox, or Rheem procedures over WiFi before the job, then keep working once you're in a basement or rural area with zero bars.

Checklist mode while working

Mark steps complete as you go. No scrolling back through a PDF to find your place mid-repair.

Confirm airflow restriction
Clear lockout at board

Bookmarked equipment, one tap away

Save the models you service most so you never re-search the same unit twice. V1 covers Carrier, Trane, Lennox, and Rheem, residential and light commercial.

From error code to job closed, one visit

Here's what a typical call on an unfamiliar unit looks like, start to finish:

Service call · Carrier Infinity 96Dallas, TX
On arrival
Unit displays error code 33. Tech has never touched an Infinity 96 before, opens Fieldkiln and searches the code.
Procedure found
Error 33: limit circuit lockout from airflow restriction. Four-step relearn sequence loads with a button diagram, downloaded for offline use.
Working the checklist
Tech clears the filter restriction, clears the lockout at the board, and runs the relearn sequence, checking off each step.
Closed
Airflow verified, system restarts clean. First visit fix, no forum thread, no callback needed.

Nobody else is built for this moment

Dozuki, VKS, and Operations1 are factory-floor knowledge tools built for a desk, not a basement. MaintainX runs your whole maintenance operation but isn't equipment-specific. Fieldkiln does one thing: get you the right manufacturer procedure on your phone, fast, while you're standing in front of the unit.

What techs ask before signing up

Which equipment brands are covered?

V1 covers Carrier, Trane, Lennox, and Rheem, residential and light commercial. More brands get added based on what technicians actually ask for.

Does it work without cell signal?

Yes. Download a brand pack over WiFi before the job, then every procedure in that pack works offline, basement or rural call included.

Is this a full field-service management tool?

No. Fieldkiln doesn't do dispatch, invoicing, or scheduling. It does one job: get you the right procedure fast. Pair it with whatever FSM tool you already run.

Can I add my own notes to a procedure?

Yes. Notes attach to the procedure and sync to your job if you connect your FSM system on the Enterprise tier.
