HVAC Tech Helper

Terms of Use

Effective November 14, 2026

These terms are an agreement between you and Ao Yang Ren (“we”, “us”), the publisher of HVAC Tech Helper (“the app”). By using the app you agree to them and to our Privacy Policy.

Safety first. The app’s AI suggestions can be wrong. They are a starting point for troubleshooting, not a diagnosis. Always confirm with your own measurements, the nameplate and the manufacturer’s instructions. Only do work you are trained and licensed for, lock out and test before touching electrical parts, and follow all rules for gas, combustion and refrigerant handling.

1. Who can use the app

The app is for trained HVAC/R technicians and apprentices working under a qualified technician. It is not for homeowners or do-it-yourself repairs. You must be at least 18 years old and confirm your status when you start using the app. You are responsible for holding the licences and certifications your work requires.

2. Your account and your company

3. AI suggestions and your responsibility

4. Customer information

When you record customer details and signatures in the app, you confirm that you are allowed to collect them for your work and that you will use them only for that purpose. Do not photograph people without their permission; use the blur tool to hide private details.

5. Your content

You and your company keep ownership of the reports, photos and text you create. You give us permission to store and process them to run the app, and to add an approved, de-identified technical summary of a case to the shared case library that helps all users. Summaries never include names, addresses, contact details, signatures or your own words.

6. Acceptable use

Do not misuse the app: no unlawful use, no attempts to access other companies’ data, to break or overload the service, to get around usage limits, or to copy the app or its case library in bulk.

7. Fees and limits

The app is currently free. AI features have daily and monthly usage limits. We may introduce paid plans; we will tell you before any charge applies, and paid features will be sold through the App Store.

8. Changes and availability

We may change, suspend or stop features. We may suspend accounts that break these terms. If we change these terms in an important way, we will ask you to accept them again in the app.

9. No warranty

The app is provided “as is” and “as available”, without warranties of any kind, including accuracy, fitness for a particular purpose and uninterrupted service, to the fullest extent the law allows.

10. Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental or consequential damages, or for property damage, injury, lost profits or lost data arising from use of the app or reliance on its suggestions. Our total liability for any claim is limited to CAD $100. Some places do not allow these limits, so they may not apply to you.

11. Apple

These terms are between you and us, not Apple. Apple is not responsible for the app or its content, has no obligation to provide maintenance or support, and is not responsible for any claims about the app. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them. Your use must also follow the App Store’s terms.

12. Governing law

These terms are governed by the laws of the Province of British Columbia and the federal laws of Canada that apply there, without limiting any consumer rights you have where you live.
