8. Professional Use Disclaimer

HVAC Pro Calculator is a calculation aid intended for licensed HVAC professionals and informed users. Results are produced from the inputs you provide using documented formulas (ASHRAE-derived load sizing, ASHRAE friction-rate equation, NEC voltage-drop method tied to NEC Table 310.16 ampacity, SMACNA HVAC Duct Construction Standards, manufacturer-supplied refrigerant P-T tables). We do not guarantee the accuracy, completeness, or suitability of results for any specific project, installation, or code submittal. The BTU / Cooling Load calculator is explicitly an estimation tool and is not a substitute for ACCA-certified Manual J software when code requires one. You are solely responsible for verifying every result against applicable codes, manufacturer specifications, local Authority Having Jurisdiction (AHJ) requirements, and your own professional judgment before purchasing materials, sizing equipment, sizing or installing wiring, charging a system, or proceeding with any installation. We are not liable for equipment damage, code violations, refrigerant loss, electrical fires, undersized or oversized systems, fabrication errors, or any other outcome resulting from reliance on calculations produced by the App.

9. Intellectual Property

The App, including its source code, graphics, design, and content, is owned by PLAYRIOT LLC and protected by copyright, trademark, and other intellectual property laws. This Agreement does not transfer any ownership rights to you. References to ASHRAE, NEC (NFPA 70), SMACNA, ACCA, and refrigerant manufacturer data are made for educational and identification purposes only; PLAYRIOT LLC is not affiliated with, endorsed by, or sponsored by any of these organizations or manufacturers.

10. Privacy

Use of the App is also governed by our Privacy Policy, which is incorporated into this Agreement by reference.

11. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS, OR THAT CALCULATIONS WILL BE ACCURATE OR SUITABLE FOR YOUR INDIVIDUAL APPLICATION.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, PLAYRIOT LLC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF THE APP — INCLUDING BUT NOT LIMITED TO EQUIPMENT DAMAGE, CODE VIOLATIONS, REFRIGERANT LOSS, ELECTRICAL FIRES, UNDERSIZED OR OVERSIZED SYSTEMS, OR FABRICATION ERRORS. OUR TOTAL LIABILITY FOR ANY CLAIM SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE APP IN THE 12 MONTHS PRECEDING THE CLAIM.

13. Termination

We may terminate or suspend your access to the App at any time, with or without cause or notice. Upon termination, your license to use the App ends immediately. Sections 8, 9, 11, 12, and 14 survive termination.

14. Governing Law

This Agreement is governed by the laws of the State of Delaware, United States, without regard to its conflict of laws principles. Any disputes shall be resolved in the state or federal courts located in Delaware.

15. Apple-Specific Terms

You acknowledge that this Agreement is between you and PLAYRIOT LLC, and not with Apple Inc. ("Apple"). Apple is not responsible for the App or its content. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any). To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App. Apple is a third-party beneficiary of this Agreement and may enforce it against you.
