GWIN Tech Assisted DIY Commissioning Guarantee, Labor Warranty, Refrigerant Warranty, and Parts Warranty Terms

The GWIN Tech Assisted DIY Commissioning Guarantee is offered in good faith as a limited service guarantee for eligible complete GWIN systems purchased from GWIN or from an authorized GWIN dealer, reseller, or GWIN-approved technician.

This Guarantee is not unlimited. It does not cover customer-caused installation errors, delays, unsafe conditions, incomplete installations, misrepresentation, bad-faith conduct, additional refrigerant before certification, leaks caused by customer installation, unauthorized work, or any condition outside GWIN Tech’s reasonable control.

This Guarantee applies only to eligible complete systems and only when the customer follows all GWIN Assisted DIY requirements, installation instructions, communication requirements, scheduling requirements, and commissioning procedures.

1. Eligible Systems Only

This Guarantee is valid only for complete GWIN HVAC systems purchased directly from GWIN or through an authorized GWIN dealer, reseller, or approved Techs.

A “complete system” means the required outdoor condenser, indoor air handler or air handlers, required communication wiring, line sets, controls, and required system components purchased together as a qualifying GWIN system.

This Guarantee does not apply to:

• Used systems.
• Open-box systems unless expressly approved by GWIN in writing.
• Incomplete systems.
• Mismatched systems.
• Systems purchased from unauthorized sellers.
• Systems with missing required components.
• Systems altered, modified, damaged, or installed outside GWIN’s instructions.
• Systems installed with non-approved parts, accessories, line sets, electrical components, refrigerant components, or controls.
• Systems installed in a manner that violates manufacturer instructions, GWIN instructions, applicable code, permit requirements, or safety standards.

2. Purpose of the Guarantee

The purpose of the GWIN Tech Assisted DIY Commissioning Guarantee is to give eligible customers access to a certified technician for commissioning after the customer completes the DIY installation.

This Guarantee is not a promise that the customer’s installation was performed correctly. It is not a promise that the system will operate if the customer’s installation is incomplete, defective, unsafe, inaccessible, delayed, improperly performed, or otherwise not ready for commissioning.

GWIN Tech’s role is to inspect, verify, and commission the system during the first eligible technician visit. GWIN Tech does not assume responsibility for the customer’s DIY installation.

3. First Technician Visit Only

This Guarantee applies only to the first scheduled GWIN Tech commissioning visit for the applicable system.

The Guarantee does not apply to any:

• Second visit.
• Return trip.
• Follow-up appointment.
• Continuation appointment.
• Repair visit.
• Diagnostic visit after the first attempted visit.
• Additional labor required after the first technician visit begins or is attempted.
• Trip caused by customer delay, customer error, incomplete installation, unsafe conditions, lack of access, missing information, or installation defects.

If the first visit cannot be completed due to any customer-side issue, the Guarantee is void.

Customer-side issues include, but are not limited to:

• Customer delay.
• Incomplete installation.
• Improper installation.
• Unsafe installation.
• Lack of access.
• Missing components.
• Missing power.
• Incorrect wiring.
• Installation-related leaks.
• Required repairs.
• Communication delays.
• Customer rescheduling.
• Customer cancellation.
• Customer not being available.
• System not being ready for commissioning.
• Any other condition caused by, created by, or within the control of the customer.
• GWIN may also determine on a case by case if the customer intended to make commissioning unsuccessful intentionally which would result in a void of this promise. 

4. Customer DIY Installation Responsibility

Customer is solely responsible for completing the DIY installation correctly, safely, fully, and in accordance with:

• GWIN installation instructions.
• Manufacturer manuals.
• Product specifications.
• Electrical requirements.
• Mechanical requirements.
• Local building codes.
• Local electrical codes.
• Local mechanical codes.
• Permit requirements.
• Safety standards.
• Any applicable federal, state, county, city, or municipal requirements.

GWIN Tech does not assume responsibility for, cover, reimburse, repair at no charge, or guarantee any customer-performed installation work.

Customer installation responsibility includes, but is not limited to:

• Mounting indoor and outdoor units correctly.
• Installing line sets correctly.
• Installing flareless or connection fittings correctly.
• Preparing fittings correctly.
• Tightening fittings correctly.
• Routing and insulating line sets correctly.
• Installing communication wiring correctly.
• Installing electrical wiring correctly by an electrician
• Ensuring proper breaker, disconnect, and electrical supply.
• Installing condensate drainage correctly.
• Ensuring the system is powered and accessible.
• Ensuring the installation is complete before the technician arrives.
• Ensuring the system is safe for the technician to inspect and commission.

5. Installation Errors, Leaks, Repairs, and Additional Charges

If the GWIN Tech finds any leak, improper installation, incomplete installation, unsafe installation, code concern, customer-caused defect, missing component, damaged component, incorrect connection, communication issue, wiring issue, refrigerant issue, or condition requiring correction before commissioning can be completed, the Guarantee is void.

GWIN Tech does not cover the cost of diagnosing, repairing, correcting, reworking, replacing, or completing customer DIY installation errors.

This includes, but is not limited to:

• Leak searches.
• Leak repairs.
• Fitting repairs.
• Line-set repairs.
• Electrical corrections.
• Drain corrections.
• Mounting corrections.
• Wiring corrections.
• Communication wire corrections.
• Condenser or air handler repositioning.
• Replacement of damaged customer-installed parts.
• Additional labor.
• Technician waiting time.
• Additional materials.
• Any second technician visit.
• Any return trip required because of customer-side issues.

Any work required because of customer installation issues must be separately agreed to and paid for by the customer. Such work must be negotiated directly between the GWIN Tech and the customer before the work is performed.

GWIN does not cover, reimburse, or pay for a second GWIN Tech visit when the second visit is required because the system was not properly installed, not ready, inaccessible, unsafe, leaking, incomplete, or otherwise unable to be commissioned during the first visit.

6. Refrigerant Exclusion Before Certification

Additional refrigerant is not included in the GWIN Tech Assisted DIY Commissioning Guarantee before the system is successfully commissioned and certified.

If additional refrigerant is needed before certification for any reason, including but not limited to line-set length, leakage, improper installation, loss of charge, evacuation issues, repair work, commissioning requirements, damaged fittings, improper connections, or customer-caused conditions, the cost of refrigerant, refrigerant labor, recovery, evacuation, recharge, leak repair, and related materials is the customer’s responsibility.

Any refrigerant-related charges before certification must be negotiated directly between the GWIN Tech and the customer.

7. Certification Requirement for 1-Year Labor and Refrigerant Warranty

The 1-Year Labor Warranty and 1-Year Refrigerant Warranty do not begin at the time of purchase, delivery, or customer installation.

The 1-Year Labor Warranty and 1-Year Refrigerant Warranty activate only after:

1. The customer completes the Assisted DIY installation;
2. A GWIN Tech performs the commissioning visit;
3. The GWIN Tech confirms the system is properly installed;
4. The GWIN Tech certifies the system is free of leaks and visible defects at the time of commissioning; and
5. The GWIN Tech successfully completes the commissioning process.

Any customer installation error, leak, defect, improper connection, missing component, unsafe condition, or installation-related issue discovered before certification is not covered under the 1-Year Labor Warranty or the 1-Year Refrigerant Warranty.

Once the GWIN Tech leaves the job site and certifies the system as successfully commissioned and good to operate, the 1-Year Labor Warranty and 1-Year Refrigerant Warranty go into effect according to GWIN’s warranty descriptions.

8. Coverage After Successful Certification

Once the system has been successfully commissioned and certified by a GWIN Tech, the applicable GWIN warranty coverage begins according to the warranty terms for that system.

Subject to the applicable warranty descriptions, exclusions, limitations, and approval requirements, coverage may include:

• Diagnosis.
• Labor.
• Refrigerant.
• Control board replacement.
• Covered parts.
• Compressor replacement.
• Warranty-approved repairs.
• Other approved warranty service as described in the applicable GWIN warranty documents.

The 10-Year Parts Warranty, where applicable, begins and applies according to GWIN’s written parts warranty terms.

The 1-Year Labor Warranty, 1-Year Refrigerant Warranty, and 10-Year Parts Warranty do not cover customer abuse, unauthorized repairs, improper maintenance, non-GWIN parts, misuse, tampering, improper electrical supply, installation changes after certification, acts of nature, code violations, or any condition excluded under the applicable warranty descriptions.

9. Damaged Units Upon Delivery

Customer must inspect all equipment upon delivery.

Any system or component with visible shipping damage must be reported to GWIN immediately at:

contact@gwinhvac.com

Customer should provide:

• Order number.
• Delivery date.
• Photos of the damaged packaging.
• Photos of the damaged equipment.
• Photos of labels, model numbers, and serial numbers.
• A description of the damage.
• Any carrier documentation, if available.

Systems with visible damage upon delivery will be evaluated by GWIN for repair, replacement, parts support, claim assistance, or another resolution determined by GWIN.

Customer should not install visibly damaged equipment unless GWIN provides written approval. Installing visibly damaged equipment without written approval may limit or void replacement eligibility, shipping damage claims, commissioning eligibility, labor coverage, refrigerant coverage, or warranty coverage related to that damage.

10. GWIN’s Process to Guarantee a Tech in Your Area

GWIN uses a multi-step process to provide eligible customers access to a certified technician. Once DIY installation is complete, the customer must call us that they are ready for a GWIN Tech. We may review DIY installation before scheduling GWIN Tech to come out and charge the system. Countdown begins after GWIN reviews DIY installation unless stated otherwise. 

Week 1: Local Tech Dispatch

In GWIN first week attempts to dispatch a local technician through its nationwide technician network. This network has been developed to support customers in many areas, including difficult, rural, and hard-to-service locations. 

Week 2: Travel-Ready Tech Dispatch

If a local technician is not available, in the second week GWIN may coordinate with a travel-ready technician who is willing to drive to the customer’s location.

When this option is required and approved by GWIN, GWIN coordinates the dispatch and covers the eligible travel arrangement for the initial commissioning visit, subject to these terms.

Week 3: GWIN In-House Tech Travel

By the third week, if neither a local technician nor a travel-ready technician is available, GWIN may send an in-house GWIN Tech to the customer’s home.

When required and approved by GWIN, this may include flying a GWIN Tech to the customer’s area. GWIN’s goal is to have a technician available within two weeks after the customer’s installation is complete, the customer has submitted all required commissioning information, and GWIN has confirmed the system is ready for commissioning.

At 30 days: Full System Refund if GWIN Cannot Provide a Certified Tech

If GWIN cannot provide a certified technician to an eligible customer within 30 days of delivery, GWIN will refund 100% of the customer’s purchase price for the qualifying system.

No return is required. No restocking fee applies. The customer keeps the equipment.

However, this refund guarantee applies only if all of the following conditions are met:

• The system was purchased from GWIN or an authorized GWIN dealer, reseller, or approved GWIN Tech.
• The system is a complete eligible GWIN system.
• Customer has completed the installation according to GWIN requirements.
• Customer has submitted all required commissioning information.
• Customer has provided requested photos, videos, documentation, and installation verification.
• Customer has responded promptly to GWIN Tech communications.
• Customer has accepted the earliest reasonable technician appointment offered.
• Customer has not delayed, rescheduled, cancelled, ignored, or refused technician scheduling.
• Customer has not prevented access to the property or equipment.
• Customer has not misrepresented the installation status.
• Customer has not engaged in conduct that voids the Guarantee.
• The delay is caused solely by GWIN’s inability to provide a certified technician, not by customer-side issues.

The 30-day refund guarantee does not apply if the technician delay is caused by customer delay, incomplete installation, improper installation, unsafe conditions, delivery damage that has not been reported or resolved, lack of access, missing information, missed communications, customer rescheduling, customer cancellation, weather, force majeure, permitting issues, utility issues, or any condition outside GWIN’s reasonable control.

16. No Waiver

If GWIN chooses to assist a customer with an issue that is not covered by this Guarantee, that assistance does not waive GWIN’s rights, does not expand the Guarantee, does not create future coverage, and does not require GWIN to provide the same assistance again.
