HVAC Vault Support
Professional HVAC troubleshooting, training, diagnostic tools, and AI-powered assistance built for HVAC technicians.
Getting Started
Download HVAC Vault, create an account, and complete the initial setup. From the home screen you can access troubleshooting workflows, diagnostic tools, training material, and the AI assistant.
Account & Login
Sign in with the credentials you used when creating your account. If you cannot sign in, use the password reset option on the login screen. If you no longer have access to the email on the account, contact support.
AI Assistant
The HVAC AI assistant provides guidance and reference support for HVAC work. You choose what you submit to it. Your AI conversations and messages may be saved to your account so your conversation history can be provided back to you. AI submissions are transmitted to third-party AI infrastructure required to generate responses — currently routed through Lovable's AI gateway infrastructure to a Google Gemini model. Avoid submitting unnecessary personal, confidential, or sensitive information to the AI assistant.
Uploading HVAC Images
You may voluntarily upload HVAC-related images for AI analysis. Uploaded images are stored in private Supabase Storage associated with your authenticated account and are transmitted to the AI infrastructure used to generate a response. Question and image usage counts are recorded to apply plan limits.
Safety & Accuracy
HVAC Vault provides educational information, troubleshooting information, training resources, diagnostic assistance, and AI-assisted information. AI-generated or troubleshooting information may not always be accurate, complete, or appropriate for every HVAC system or equipment configuration. You remain responsible for following manufacturer documentation, electrical and mechanical codes, and proper safety procedures, using appropriate PPE, verifying equipment specifications, and exercising professional judgment. HVAC Vault and Jownah Labs do not replace required professional training, licensing, certification, manufacturer documentation, or appropriate safety procedures.
Subscription & Billing
Web subscriptions are processed by Stripe. HVAC Vault does not store your full payment card number. The app maintains the information needed to manage subscription access, including your plan, subscription status, subscription period and renewal information, Stripe customer identifier, and Stripe subscription identifier. The mobile application is being prepared for Apple App Store and Google Play billing.
Troubleshooting
Try these steps first: fully close and reopen the app, confirm you are on the latest version, check your internet connection, then restart your device. If the issue continues, contact support with your device model, OS version, and app version.
Report a Bug
Send us a description of what happened, the steps to reproduce it, and a screenshot or screen recording if possible. Include your device model, OS version, and app version so we can reproduce the issue quickly.
