Train across HVAC, Plumbing, Electrical, and Welding with dedicated AI Senseis. EPA 608, A2L, R-454B, NATE prep — all included. Apprentice tier is free. Future franchisees get AI Maestro Cloud bundled as the operational backbone.
ATH meets you wherever you are — entering the trades for the first time, or scaling a contracting business toward a franchise model.
Years 1-4 of your career: free unlimited AI Sensei chat, EPA 608 prep, A2L + R-454B training, NATE drilling, equipment database, code library, mentor tracking.
Cross-train across HVAC + Plumbing + Electrical + Welding. Each trade has its own dedicated AI Sensei — Socratic-style drilling tuned to that domain.
Graduate from Apprentice (free) to Journeyman ($499/mo) when you're managing your own apprentices, then to Contractor Fleet for multi-location operators.
No incumbent (One Hour, Aire Serv, Ben Franklin) trains technicians from day-one. ATH does. That's the moat: pipeline economics > recruiting economics.
Future ATH franchisees get AI Maestro Cloud — fractional CFO AI, fractional general-counsel AI, multi-agent orchestration — included. No incumbent matches this.
600K HVAC/electrical/plumbing jobs posted vs 150K new apprentices entering annually (US). AGC: 92% of contractors can't find qualified hourly workers. ATH owns the supply side.
Domain-trained. Socratic-style. Unlimited drills. Each Sensei tracks specific equipment by model number, surfaces relevant code citations (EPA 40 CFR, NEC, IMC, ASHRAE), and ladders your progress through the certification pathway.

We're building the FDD — Franchise Disclosure Document — through 2026. Pilot Franchisee #1 candidate is in conversations. When ATH opens to outside operators, qualified franchisees will get:
| Franchise | Initial Inv | Fee | Royalty |
|---|---|---|---|
| One Hour Heating & Air | $134K-$312K | $43K | 6% / $1.5K min |
| Aire Serv (Neighborly) | $88K-$216K | $40K | 5-7% |
| Benjamin Franklin Plumbing | $143K-$287K | $43K | TBD |
| ATH (post-FDD) | TBD | TBD | TBD |
We're not selling franchises yet — we're collecting interest from qualified operators so we can prioritize the FDD. Drop your details and we'll loop you in when the disclosure document drops.
Direct answers. Same answers our AI Senseis would give.
Advanced Training HVACR (ATH) is an AI-powered trades mastery platform with dedicated AI Senseis across HVAC, Plumbing, Electrical, and Welding. The Apprentice tier (Years 1-4) is free with unlimited Sensei chat, EPA 608 prep, A2L and R-454B training, NATE prep, equipment database, and code library. Operated by Torus LLC.
Three tiers: Apprentice (Years 1-4) is free. Journeyman is $499/month plus $499 setup and adds apprentice management, job management, QBO/HubSpot/Zoho integration, and a KPI dashboard. Contractor Fleet is custom pricing for multi-location operators with white-label, full API, SSO/SAML, and dedicated account management.
EPA 608 (Type I, II, III, and Universal), NATE certification (per track — Air Conditioning, Heat Pump, Gas Heating, Light Commercial, HVAC Efficiency Analyst), A2L refrigerant handling, and R-454B field service. New tracks added as the AI Senseis expand across plumbing, electrical, and welding trades.
Yes. Online HVAC training is widely accepted for the theoretical and code components of certification. The EPA 608 exam itself can be taken online (Type I) or in-person (Types II, III, Universal). NATE testing requires proctored exam centers. ATH preps you for both — the AI Senseis run unlimited diagnostic drills before you sit the exam.
An AI Sensei is a domain-trained AI tutor specialized in one trade. It runs Socratic-style diagnostic drills, troubleshoots specific equipment by model number, surfaces relevant code citations, and tracks your progress across the certification pathway. The HVACR Sensei is rated at 92% accuracy across 5,200+ training sessions.
Yes — ATH is building a franchise model launching post-FDD in 2026. The wedge no incumbent has: train-from-day-one through ATH then graduate to franchise operator. Future franchisees get AI Maestro Cloud bundled as the operational backbone.
SkillCat and HVACRedu are training platforms — they teach the curriculum. ATH adds two layers on top: dedicated AI Senseis per trade for unlimited Socratic-drilling, and a franchise pipeline so successful trainees can move from technician to fleet operator. Apprentice tier is free at ATH; SkillCat starts at $10/month. Multi-trade scope (HVAC + Plumbing + Electrical + Welding) is unique to ATH.
A2L refrigerants are mildly flammable, low-GWP refrigerants replacing high-GWP A1 refrigerants like R-410A across new HVAC equipment in 2026. R-454B is the most common A2L for residential and light commercial. ATH's A2L training covers safety classification, leak detection, equipment-compatibility codes, and field-service procedures.
