Terms of service

The agreement between your shop and MLJ, SASU for the use of SeasonTuneUp. Last updated March 2, 2026.

1. Acceptance of these terms

These terms form a binding agreement between MLJ, SASU, the company that publishes SeasonTuneUp and whose registration details appear on the legal notice, and the business that subscribes to the service. By creating an account, by paying an invoice, or by using any part of the service, you accept these terms on behalf of that business and confirm you are authorized to do so. If you do not accept them, do not use the service.

2. What the service does

SeasonTuneUp is a web based subscription service for residential HVAC contractors that sell maintenance agreements. It stores the agreements you have sold, tracks each one to its renewal date, sends renewal notices by email and text message, attempts card and ACH renewal charges with a retry sequence, records the equipment installed at each service address, keeps a ledger of the seasonal visits promised and delivered, and provides a booking board that places spring cooling and fall heating tune ups on your schedule. The service is delivered over the public internet through a standard web browser. It is a record keeping and scheduling tool. It does not perform HVAC work, it does not give technical or regulatory advice, and it is not a substitute for your own judgment about what a customer's equipment needs.

3. Accounts and eligibility

The service is sold to businesses, not to consumers. To open an account you must be a legally constituted business operating in the United States and the person who registers must be at least eighteen years old. You are responsible for the accuracy of the account information you give us, for keeping login credentials confidential, and for everything done under your accounts, including by your employees and subcontractors. Tell us promptly at jimenezjulien42@gmail.com if you believe an account has been compromised.

4. Acceptable use

You agree to use SeasonTuneUp only for your own business and only in compliance with the law. You will not upload customer contact data you have no right to use, send messages through the service to people who have asked you not to contact them, or use the messaging features for anything other than communication about the maintenance agreements and service visits you have with those customers. You are responsible for compliance with telephone and text messaging rules that apply to your business, including consent requirements and quiet hours in the states where you operate. You will not attempt to break, probe or overload the service, resell access to it, or copy its interface or content into a competing product.

5. Subscription plans and billing

Three plans are offered. Owner Operator is $45 per month and covers up to 300 active agreements. Growing Shop is $99 per month and covers up to 1,500 active agreements. Multi Truck is $229 per month and covers an unlimited number of agreements along with multiple locations. All prices are in United States dollars, are stated exclusive of any applicable sales tax, and are billed monthly in advance on the anniversary of the day you started. There is no setup fee, no annual commitment and no charge per user seat.

If your active agreement count passes the limit of your plan, we will tell you and move you to the plan that fits, with the difference prorated on your next invoice. You may change plans yourself at any time in the billing screen. Payment is by card or by ACH debit. If a payment fails we will retry it and notify you. If an invoice stays unpaid for fourteen days after the due date we may suspend access until it is settled, and your data remains intact during any such suspension.

6. Cancellation

You can cancel at any time from the billing screen, without calling anyone and without giving a reason. Cancellation takes effect at the end of the monthly period you have already paid for, and the service stays fully usable until then. We do not refund partial months. For thirty days after cancellation you keep read and export access to every agreement, equipment record, visit history and renewal note, in CSV and PDF. After those thirty days the account and its contents are permanently deleted. We may suspend or terminate an account that breaches section 4, and we will explain why in writing when we do.

7. Your data

Everything you put into SeasonTuneUp remains yours. That includes your customer list, your agreement terms, your equipment records, your visit history and your notes. We process that data only to operate the service for you, we do not sell it, we do not share it with advertisers or data brokers, and we do not use it to train automated systems. You can export it in full at any time. Handling of personal data collected through this website is described in the privacy policy. You are the controller of your customers' personal data and are responsible for having a lawful basis to hold and contact them.

8. Availability and support

We aim for 99.9 percent monthly availability and we publish planned maintenance in advance. Planned maintenance is scheduled outside United States business hours and never during the first two weeks of March or the first two weeks of September, which are the weeks this trade cannot spare. Support is by email at jimenezjulien42@gmail.com on business days, with a target first reply inside one business day and the same treatment on every plan. Multi Truck accounts also get a named contact and phone access.

9. Warranty disclaimer

The service is provided on an as is and as available basis. To the fullest extent permitted by law, we disclaim all implied warranties, including implied warranties of merchantability, fitness for a particular purpose and non infringement. We do not warrant that the service will be uninterrupted or error free, that every renewal notice or text message will be delivered by the networks that carry it, or that any specific renewal rate, booking rate or revenue result will follow from using it. Benchmark figures published on this website are observed medians, not promises.

10. Limitation of liability

To the fullest extent permitted by law, neither party is liable for indirect, incidental, special or consequential damages, or for lost profits, lost revenue or lost business opportunity, arising out of or relating to the service. Our total aggregate liability for any claim relating to the service is limited to the subscription fees you actually paid us in the twelve months before the event that gave rise to the claim. Nothing in these terms excludes liability that cannot lawfully be excluded, including liability for fraud or for gross negligence.

11. Indemnity

You agree to indemnify and hold MLJ, SASU harmless from claims, damages and reasonable costs arising from your use of the service in breach of these terms, from data you upload that you had no right to use, or from messages sent through the service to recipients who had not consented to receive them.

12. Changes to these terms

We may update these terms as the service changes. Material changes are announced by email to the account owner and posted here at least thirty days before they take effect, and the date at the top of this page is updated. If you keep using the service after a change takes effect, you accept the updated terms. If you do not accept them, cancel before the effective date and section 6 applies.

13. Governing law and contact

These terms are governed by French law. Any dispute that cannot be settled amicably falls under the exclusive jurisdiction of the competent courts of Paris, France. If any provision is held unenforceable, the rest stays in force. Questions about these terms go to MLJ, SASU, for the attention of Jimenez Julien, at jimenezjulien42@gmail.com.
