Terms and Conditions

Effective Date: October 11, 2026

Welcome to VentilatePro.com, operated by Patil Engineers, a sole proprietorship based in Maharashtra, India ("Patil Engineers," "we," "us," or "our"). These Terms and Conditions ("Terms") govern your access to and use of our website, services, and digital products, including the VentilatePro HVAC engineering software, its AI features, Pro subscriptions, and access codes for Professional Engineer (PE) practice exams (collectively, the "Services"). By accessing or using our Services, you agree to be bound by these Terms. If you do not agree, please do not use our Services.

1. Scope of Services

VentilatePro provides HVAC engineering software for design work, including load and ventilation calculations, project tools, a Revit add-in, a command-line tool and an MCP server that lets AI agents work in your projects, together with AI features such as the Mimir assistant and AI drawing reviews. VentilatePro also sells access codes for PE practice exams. Plans, prices and usage limits are described on our Pricing page. All content, data, and materials we provide through our Services are proprietary and subject to these Terms.

2. User Eligibility and Responsibilities

By using our Services, you represent and warrant that you are at least 18 years of age and have the legal capacity to enter into these Terms. You agree to:

  • Provide accurate and complete information when creating an account or purchasing access codes.
  • Maintain the confidentiality of your account credentials and access codes.
  • Use the Services for your own professional or personal work, and not resell them or provide them to others.

Prohibited Activities: You may not:

  • Share, distribute, or transfer access codes to any third party. Access codes are strictly for individual use and are non-transferable.
  • Copy, reproduce, modify, or distribute any content, questions, or materials from our Services, including practice exam questions, all of which are proprietary and protected by intellectual property laws.
  • Attempt to reverse-engineer, decompile, or access the underlying code or structure of our Services.
  • Use automated access, including MCP and the command-line tool, in a way that disrupts the Services for others, gets around plan limits, or goes beyond fair use.
  • Use our Services for any unlawful or unauthorized purpose, including violating applicable laws in the United States or India.

3. No Guarantees and Engineering Responsibility

While our Services are designed to assist in PE exam preparation, we make no representations or warranties regarding your ability to pass the PE exam or achieve any specific outcome. Success on the PE exam depends on numerous factors beyond our control, including your preparation, knowledge, and performance. You acknowledge that use of our Services does not guarantee passing the PE exam or obtaining licensure.

VentilatePro is a design aid, not a professional engineering service. Calculation results, AI-generated content and drawing review findings can be incomplete or wrong, and must be checked by a qualified engineer before they are relied on. You remain responsible for your designs, drawings, and compliance with applicable codes and standards.

4. Intellectual Property

All content, materials, and data provided through our Services, including but not limited to practice exam questions, text, graphics, and software, are the exclusive property of Patil Engineers or its licensors and are protected by copyright, trademark, and other intellectual property laws. You are granted a limited, non-exclusive, non-transferable license to access and use the Services for your own professional or personal work, subject to these Terms.

You own the project data and files you put into VentilatePro. You give us permission to store, process and display them, including by sending them to AI providers when you use an AI feature, only as needed to provide the Services to you.

5. Payment Terms

By purchasing access codes or other Services, you agree to pay the fees specified at the time of purchase. All payments are subject to our Refund and Cancellation Policy, which governs refunds, cancellations, and non-refunded used access codes. You are responsible for providing valid payment information and resolving any payment disputes directly with your payment provider. VentilatePro is not liable for errors or delays caused by third-party payment processors.

Pro subscriptions. Pro is billed monthly in advance and renews automatically until you cancel. You can cancel at any time, and Pro stays active until the end of the period you paid for. The weekly AI allowance, storage, and fair-use MCP access are described on the Pricing page. We will give you at least 30 days' notice of a price change before it applies to your next renewal. Prices are in US dollars, and taxes may apply.
