AI Master Tech · on site, at the machine
46 years of troubleshooting, on every service call
Stuck on a tough call? Enter the model, the symptom and any error code. ThermalForce HQ triages the most common problems for that exact machine, walks you through starting its diagnostic mode, then guides you test by test until you find the fault — with the schematic, the part and the supplier one tap away.
AI triage: the most common problems
Enter the model, the symptom and any error code (type it or say it). Get the top probable causes for that exact machine ranked High / Medium / Low, what the fault code means for that brand, and the root cause explained.
Start diagnostic mode on that machine
Step-by-step instructions to enter service or test mode on the model in front of you — the exact buttons and sequence — and how to exit when you're done.
Troubleshoot step by step
An ordered test sequence, cheapest and safest checks first, with expected ohms and voltages. Tap Pass or Fail on each test and save the results to the job. Safety warnings come first — power, capacitors, gas and refrigerant.
Schematics & wiring diagrams
Open the schematic, wiring diagram and parts list for the model right on the job. Add your own library of diagrams and OEM part numbers for your team.
Get the part
See if it's on your truck or in the warehouse. If not, the parts suppliers are already set up — one tap searches the model, and the part goes on the ticket.
Tap to talk — hands-free on the job
Hands full or gloves on? Tap the mic and say it. Symptoms, error codes (“F twenty-one” becomes F21), model numbers, your diagnosis, work completed and photo notes fill in by voice — in the diagnostics and across the whole job ticket.
Parts suppliers already set up — search the model in one tap:
- Marcone
- Encompass
- Repair Clinic
- Parts Dr
- Johnstone Supply
- Ferguson
- Bluon
- Parts Town
- WebstaurantStore
AI diagnostics are included on Pro (30 a month, shared) and Small Team (2,000 a month, shared). AI guidance supports a qualified technician's judgment — always confirm against the manufacturer's tech sheet and follow safe work practices.

FAQ
Common questions
What is the best software for an appliance repair business?
Look for software built around the appliance itself, not just the appointment: model and serial capture, parts organized by brand and appliance, truck stock, diagnostic fees and on-site payment. ThermalForce HQ was built by appliance repair techs to do exactly that, alongside dispatch, invoicing and online booking.
Can technicians capture model and serial numbers without typing?
Yes. The technician takes a photo of the rating tag and AI reads the model and serial numbers into the job. They can correct any character by typing or by voice.
Does it track parts on each technician's truck?
Yes. Each truck is its own stock location. Techs load parts from the warehouse, return them, and see what's on board — parts used on a job come off inventory automatically.
Can I charge a diagnostic fee and mark up parts?
Yes. Set a default diagnostic fee and parts markup in your invoice settings, and price parts at retail or cost plus markup on each job.
Is there a free trial?
Yes — 14 days free with no credit card needed, plus a live demo company you can open right now.
