Terms and Conditions: By using our offers, you agree to the terms below, which are designed to protect both parties and ensure transparency. 1. How to Redeem Special Offers To take advantage of our offers, visitors must book an appointment using the provided Book Appointment Form by clicking on the blue button available on this page. The request must be successfully submitted to our CSR (Customer Service Representative) team before the expiration date specified for the offer. For offers with expiration dates falling on the same day as the request, we accept submissions until 23:59 (11:59 PM) of the prior day. During the booking process, you must include the offer code in your form submission or explicitly mention the code when calling us directly. Offers will not be valid if the code is not provided during the booking process or if the expiration date has passed. The CSR team will only apply the promotional code once the code is verified and the booking is confirmed. 2. Offer Redemption Rules Each offer is valid for a single job appointment only. Offers cannot be combined, stacked, or used in multiple ways. A customer may redeem only one offer per appointment to ensure fairness and compliance. 3. Expiration and Late Redemption Policy We understand that unforeseen circumstances may arise. While our offers are designed to expire as stated, we aim to ensure flexibility and fairness: 3.1. Delays Due to Supply Chain Issues In the rare case of a delay caused by supply chain disruptions from third-party distributors for parts or equipment, customers will have the option to late redeem the offer even after the expiration date has passed. This extension applies to the same service and will honor the original offer with either the same or a similar product or equipment. 3.2. Unavailability of Parts at the Time of Service If specific parts or equipment are unavailable at the time of your scheduled service, we will provide the option to redeem the offer at a later date, even if the original expiration date has passed. This ensures you receive the full value of the offer without additional inconvenience. 4. Fair Use Policy Our offers are intended for personal use and designed to deliver value to our community. We reserve the right to deny redemption in cases of misuse, such as attempts to manipulate the system, use fake codes, or combine multiple offers in violation of these terms. 5. Trust, Safety, and Transparency At SumZero Energy Systems, our mission is to ensure that you feel safe and valued while doing business with us. These offers reflect our commitment to providing accessible, high-quality services. Here's how we ensure your peace of mind: Dedicated Support: Our CSR team is here to assist you at every step of the process, from booking to service completion. Flexibility: We prioritize customer satisfaction and make adjustments, such as late redemptions, whenever possible. No Hidden Surprises: We clearly communicate all terms upfront to ensure transparency and trust. 6. Disclaimer While we strive to fulfill all services promptly, external factors such as weather, supply chain delays, or equipment unavailability may impact service delivery times. If any delay affects your service, we will notify you immediately and provide options to honor your offer. 7. Updates to Terms and Conditions These terms and conditions are subject to updates and changes to ensure compliance with our policies and provide the best customer experience. The latest terms will always be available on this page. Thank you for choosing SumZero Energy Systems! We're proud to serve you and are committed to making your experience with us exceptional.
