TERMS OF SERVICE

HVAC Office Solutions LLC dba Mainstreet MEP®

Effective Date: July 24, 2026 | Last Updated: July 24, 2026

These Terms of Service (“Terms”) govern your use of the websites myhvacoffice.com and mainstreetmep.com, and all services, tools, reports, dashboards, assessments, integrations, digital products, subscriptions, portals, courses, podcasts, and related offerings (collectively, the “Services”). The websites and Services are owned and operated by HVAC Office Solutions LLC dba Mainstreet MEP® (“Company,” “we,” or “us”).

By accessing or using any part of the Services, purchasing a product, creating an account, connecting an integration, or affirmatively accepting these Terms at checkout, you agree to be legally bound by these Terms, without limitation or qualification. If you do not agree, you may not access or use the Services.

1. Geographic Restrictions

All Services and access to myhvacoffice.com, mainstreetmep.com, and any associated programs or software are intended solely for users physically located within the United States of America.

We do not knowingly provide Services outside the United States. If you access the Services from outside the U.S., you do so at your own initiative and risk and are responsible for compliance with local laws. We reserve the right to suspend or terminate access if we determine Services are being accessed from outside U.S. jurisdiction.

2. Scope of Services

The Services may include, without limitation:

• Financial, corporate, or valuation reports based on customer-provided or connected data
• Business assessments, tools, calculators, courses, Blueprints, templates, downloads, and other digital products
• Report delivery through secure portal access and/or to your designated email address
• Data integrations with third-party accounting systems such as QuickBooks Online (QBO) and future platforms
• Live dashboard access and historical reporting for active subscribers
• Public educational content, including the Trade Finance in Ten podcast
• Business advisory, leadership coaching, and customized consulting services offered under separate written agreements

We reserve the right to change, suspend, modify, or discontinue any part of the Services at any time, with or without notice, including adding or removing features or modifying subscription tiers.

Quarterly Advisory, Elite Advisory, Private Leadership Coaching, Specialty Advisory Engagements, and other customized services require a separate signed agreement, service schedule, order form, or statement of work. If a signed agreement conflicts with these Terms, the signed agreement controls for the specific service covered by that agreement.

3. Account Registration and Responsibility

To access certain features, you may be required to register and provide accurate, current, and complete information.

You are solely responsible for:

• Maintaining confidentiality of login credentials
• All activity under your account
• Ensuring your provided email address remains accurate and secure

You agree to notify us immediately of any unauthorized access or suspected breach of your account.

4. Fees, Billing, Cancellation, and Refund Policy

Fees may be charged on a one-time or recurring subscription basis. By subscribing or purchasing any product or report, you agree to:

• Pay all applicable fees using a valid payment method
• Authorize recurring charges where applicable
• Review and accept the product name, price, billing frequency, minimum commitment, cancellation terms, and other material terms displayed at checkout

Except as expressly required by applicable law or expressly stated in a signed agreement or checkout offer, all fees are non-refundable and non-creditable. You understand and agree that onboarding, portal configuration, report preparation, digital access, course access, and data integrations require time and operational resources regardless of usage, satisfaction, or future termination.

Because access to courses, Blueprints, templates, downloads, and other digital products may be delivered immediately, those purchases are final once access is provided, except as required by law or expressly stated at checkout.

Unless the applicable checkout states otherwise, Command Center™ subscriptions renew monthly until canceled. You may cancel through an available online account function or by emailing [email protected] from the email associated with the subscription. Cancellation stops future renewals and becomes effective at the end of the current paid billing period. Monthly charges are not prorated or refunded. Setup and onboarding fees are non-refundable after setup work begins.

If a payment fails, Company may retry the charge, suspend access or report delivery, or terminate the applicable Service. You remain responsible for fees incurred before cancellation, suspension, or termination.

5. Data Usage and Client Content

You grant HVAC Office Solutions LLC dba Mainstreet MEP® the right to access, use, process, and store all data submitted through the Services, including:

• Personal information
• Corporate and financial data submitted directly or imported from third-party platforms
• Assessment, course, and application responses
• Uploaded files and communications

We use this data solely to provide, support, secure, and administer the Services described, enforce our agreements, and comply with legal obligations. Additional information about our data practices appears in the Privacy Policy.

6. Report Delivery and Customer Responsibility

Reports and dashboards may be delivered through:

• Secure portal access
• Your designated email address

You acknowledge:

• Email transmission occurs across networks outside our control
• We cannot guarantee security once delivered to your email
• You are responsible for securing your own credentials and devices

You may use reports internally within your business and share them with professional advisors (e.g., CPA, attorney, lender) for legitimate business purposes. You may not reproduce, commercialize, publish, or distribute reports publicly without written authorization.

6a. Command Center™ Data Limitations

Command Center™ reports are generated from transactions marked as cleared in the Client’s connected QuickBooks Online account at the time of each scheduled data pull.

Transactions entered, changed, reclassified, matched, cleared, or reconciled after the data pull will not appear until a later refresh. Cleared status does not mean that a transaction has been reconciled, independently verified, or correctly categorized.

Company does not guarantee the accuracy, completeness, timeliness, or reliability of the underlying QuickBooks Online data. You are responsible for ensuring that transactions are entered promptly, categorized correctly, and cleared before the scheduled data pull.

Company does not perform bookkeeping, reconciliation, account coding, auditing, attestation, fraud detection, or verification of your financial records. Command Center™ reports reflect the information available in QuickBooks Online at the time of the pull and may change when your books are updated.

Friday delivery is an operating target, not a guaranteed deadline. Delivery may be delayed by incomplete data, authorization problems, third-party outages, system maintenance, email filtering, holidays, or events outside Company’s reasonable control.

6b. Group Coaching and Live Call Terms

This section applies only to live group coaching programs, webinars, or community calls offered by Company when those programs are expressly identified as group offerings.

Confidentiality: Information shared by other members during live calls is confidential. You agree not to disclose, share, or discuss other members’ business information, questions, or comments outside the group without their express permission.

Recording by Company: Group calls may be recorded and shared with current program members only when recording is disclosed for that program. By participating after receiving that disclosure, you consent to being recorded. Private advisory or coaching sessions are not recorded unless all participants separately agree in writing.

No Member Recording: You may not record, screenshot, capture, or redistribute any portion of live calls, chat discussions, or related group communications without prior written permission from Company.

Code of Conduct: You agree to participate respectfully and professionally. Personal attacks, discriminatory language, political debates, sales solicitations to other members, and disruptive behavior are prohibited. Company reserves the right to remove any member whose conduct negatively impacts the group experience, without refund.

Attendance: Participation in live calls is optional. Missed calls do not entitle you to refunds, credits, or makeup sessions.

7. Data Transmission and Security Disclaimers

While we employ commercially reasonable safeguards consistent with U.S. standards, you acknowledge:

• No data system or transmission method is 100% secure
• Data may transmit between systems to provide Services
• Online transmission carries inherent risks

To the maximum extent permitted by law, Company disclaims liability for unauthorized access, interception, system intrusion, or data loss resulting from circumstances beyond Company’s reasonable control.

8. Intellectual Property and Anti-Replication Protections

All content, code, reports, dashboards, templates, courses, Blueprints, financial models, calculations, data structures, valuation methodologies, visualizations, integrations, workflows, digital materials, and related outputs (collectively, “Proprietary Materials”) are the exclusive property of HVAC Office Solutions LLC dba Mainstreet MEP® or its licensors.

Access to the Services grants a limited, non-exclusive, non-transferable, revocable license to use Proprietary Materials solely for your internal business purposes.

You may not:

• Copy, reproduce, duplicate, archive, or redistribute Proprietary Materials
• Reverse engineer, decompile, disassemble, inspect, or extract underlying formulas, calculations, data mappings, logic, structures, source elements, or workflows
• Create derivative works
• Replicate report layouts, dashboard architecture, financial categorization logic, calculations, delivery methods, or methodologies
• Use Proprietary Materials to build, train, test, benchmark, or assist in building a competing reporting, course, software, consulting, or advisory system
• Share login credentials or provide unauthorized access

Unauthorized replication constitutes material breach and may result in immediate suspension or termination, injunctive relief, damages, and recovery of attorneys’ fees.

9. Protection of Trade Secrets and Proprietary Information

You acknowledge that the Services provide access to proprietary methodologies, financial frameworks, report structures, dashboard architectures, data categorization logic, calculations, delivery workflows, valuation models, course materials, and related confidential business information (collectively, “Trade Secrets and Confidential Materials”) that constitute trade secrets and proprietary intellectual property of HVAC Office Solutions LLC dba Mainstreet MEP®, protected under the federal Defend Trade Secrets Act (18 U.S.C. §1836 et seq.) and applicable Oklahoma law.

Nothing in these Terms creates or implies an employment, agency, partnership, joint venture, or fiduciary relationship between you and Company. You are a customer accessing Services on a contractual basis only.

As a condition of access, you agree that you will not:

• Use, disclose, reproduce, or transmit Trade Secrets and Confidential Materials outside the scope of your permitted internal business use
• Use Trade Secrets and Confidential Materials to design, develop, build, or assist in building a substantially similar reporting, dashboard, course, valuation, financial advisory, or business-support product or service targeted to service trades businesses
• Reverse engineer or extract proprietary methodologies, formulas, calculations, data mappings, or structures from any report, dashboard, course, integration, or output

These obligations are grounded in trade secret and intellectual property law and apply for so long as the information qualifies as a trade secret, and for a minimum of three (3) years from your last access to the Services, regardless of the reason for termination.

Nothing in this section prohibits you from operating your own trade or service business in the normal course, provided you do not misappropriate or replicate Company’s Proprietary Materials or Trade Secrets. Unauthorized use or disclosure constitutes misappropriation of trade secrets and breach of contract, entitling Company to injunctive relief, damages, and attorneys’ fees.

10. No Warranties; No Licensed Professional Advice; No Fiduciary Relationship

All Services are provided “as is” without warranty of any kind. We do not guarantee that:

• Reports, courses, templates, calculations, or other outputs will be error-free
• Integrations will remain functional
• Access or delivery will be uninterrupted
• Any Service will produce a particular financial, operational, leadership, compliance, financing, valuation, or business result

Courses, digital products, podcast episodes, free materials, calculators, templates, and other public or self-service content are provided for general informational and educational purposes only. They are not based on your complete financial records or specific facts and do not constitute legal, tax, accounting, audit, investment, employment-law, safety, licensing, mental-health, or other licensed professional advice.

Trade Finance in Ten and other podcast or public content is general education, not advice specific to any listener, company, transaction, employee, or situation. Listening to, downloading, or acting on public content does not create a client, advisory, fiduciary, or professional relationship. You are responsible for evaluating whether information applies to your circumstances and for consulting qualified professionals before making significant decisions.

Company may provide business advisory, management consulting, or leadership coaching only when expressly described in a separate signed agreement. Even then, Company does not act as your CPA, auditor, attorney, broker, investment adviser, licensed therapist, company officer, director, employee, or fiduciary unless a separate written agreement expressly and lawfully states otherwise.

Nothing in the Services creates a partnership, agency, joint venture, employment, or fiduciary relationship between you and Company.

11. Customer Notice and Reasonable Opportunity to Remedy

You are responsible for promptly reviewing products, reports, access credentials, billing, integrations, downloads, and other deliverables and notifying Company in writing if you believe there is an error, defect, delivery problem, billing issue, nonconformity, or other problem with any Service.

Your notice must provide reasonable detail and any information Company reasonably requests to investigate the issue. Before seeking a refund, credit, chargeback, cancellation for cause, damages, or other remedy, you agree to give Company a reasonable opportunity to investigate and, when appropriate, correct, reperform, replace, restore access to, or otherwise remedy the affected Service.

Company may determine the reasonable method of cure based on the nature of the Service and the issue reported. A reported issue does not automatically entitle you to a refund, credit, replacement, or extension. Failure to provide prompt notice and a reasonable opportunity to cure may limit the remedies available to you to the maximum extent permitted by law. This section does not limit any right that cannot lawfully be waived.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, COMPANY SHALL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, OR SPECIAL DAMAGES, INCLUDING LOST PROFITS, DATA LOSS, LOSS OF BUSINESS OPPORTUNITY, OR BUSINESS INTERRUPTION.

Company’s total cumulative liability arising out of or relating to the Services shall not exceed the total fees paid by you for the affected Service in the three (3) months immediately preceding the claim. Any claim must be brought within one (1) year from the date it first arose or it is permanently barred, to the maximum extent permitted by law.

13. Dispute Resolution and Governing Law

Before initiating arbitration, the parties agree to attempt good-faith resolution. The party raising a dispute must provide written notice describing the issue and requested resolution. If unresolved after thirty (30) days, the parties agree to participate in non-binding mediation administered by the American Arbitration Association (AAA) in Rogers County, Oklahoma.

If mediation does not resolve the dispute, it shall be resolved exclusively through binding arbitration administered by AAA under its Commercial Arbitration Rules. Arbitration shall occur in Rogers County, Oklahoma and be governed by the Federal Arbitration Act and Oklahoma law.

You waive:

• Any right to a jury trial
• Any right to participate in class or representative actions

14. Injunctive Relief

Company may seek immediate injunctive relief in Oklahoma courts to protect intellectual property, Trade Secrets and Confidential Materials, account security, or data, or to enforce the obligations set forth in Sections 8 and 9. You consent to personal jurisdiction in Rogers County, Oklahoma for purposes of such relief.

15. Indemnification and Attorneys’ Fees

You agree to indemnify and hold harmless HVAC Office Solutions LLC dba Mainstreet MEP®, its owners, officers, employees, contractors, and affiliates from claims arising from:

• Your use or misuse of the Services
• Violation of these Terms
• Misuse of Proprietary Materials or Trade Secrets
• Information, files, or data you provide without proper authority
• Decisions or actions taken by you or your business based on the Services

If Company prevails in enforcing these Terms, Company shall be entitled to recover its reasonable attorneys’ fees and enforcement costs. Nothing herein grants you a reciprocal right to recover attorneys’ fees unless required by non-waivable law.

16. Force Majeure

Company shall not be liable for delays or failure to perform due to events beyond its reasonable control, including natural disasters, cyberattacks, government action, labor disputes, utility failures, internet or email disruptions, or third-party outages.

17. Termination

We may suspend or terminate access at any time for violation of these Terms, misuse, security concerns, or nonpayment. Termination does not entitle you to a refund except as required by law or expressly stated in a signed agreement.

Sections concerning fees, intellectual property, trade secrets, confidentiality, disclaimers, notice and cure, limitations of liability, disputes, indemnification, attorneys’ fees, and any other provisions that should reasonably survive will remain in effect after termination.

18. Changes to Terms

We may update these Terms at any time. Updates will be posted with a revised Effective Date. Continued use of the Services after the revised Terms take effect constitutes acceptance of the revised Terms.

19. Entire Agreement and Severability

These Terms, the applicable checkout or order details, and the Privacy Policy constitute the entire agreement governing self-service and automated Services and supersede prior understandings relating to those Services.

If the parties enter into a signed advisory agreement, coaching agreement, service schedule, order form, or statement of work, that signed document controls over these Terms regarding the specific service it covers.

If any provision is held unenforceable, it shall be modified to the minimum extent necessary, and the remaining provisions remain in full force and effect.

20. Contact Information

This document does not constitute legal advice. HVAC Office Solutions LLC recommends that all parties seek independent legal counsel prior to acceptance.
