GWIN is the only DIY mini split warranty that stands behind a homeowner self-install. Parts and compressor are covered for ten full years and shipped free. Year one adds bumper-to-bumper labor and refrigerant — covering leaks the tech didn't catch at commissioning — with no deductible. Coverage on your install begins the day a licensed GWIN tech commissions and certifies the system.
Most DIY mini split warranties void the moment a homeowner does the install. GWIN's does the opposite — once a licensed GWIN tech commissions and certifies your system, full coverage engages and stays with the equipment for ten years.
Labor, refrigerant, and tech commissioning — with no deductible.
A full decade of parts and compressor coverage, shipped free to your door.
A licensed HVAC tech is included with every system — never an upsell.
Nearly every DIY mini split warranty voids the moment a homeowner does the install. GWIN works the opposite way: coverage attaches to your self-install the day a licensed GWIN tech commissions and certifies the system.
Before a tech certifies, the install work is yours (and must be complete and ready) — meanwhile GWIN still has your back on the equipment.
The day after a licensed GWIN tech commissions the system and certifies the install, full coverage engages — your install and the tech's work are covered.
Stated plainly, because the difference is the point: For other DIY HVAC manufacturers, a self-install is the fastest way to void a mini split warranty. This is where GWIN is different.
Most DIY warranties end where your install begins. GWIN's starts there.
If your compressor fails from a manufacturer defect within one year of commissioning and a licensed tech confirms it, GWIN will ship you a brand-new condenser and cover cost of the labor to install and recommission it, as part of your year-1 bumper to bumper warranty.
GWIN's warranty follows the equipment and the original commissioning date — not the owner. If you sell your home, both the year-1 and 10-year coverage transfer automatically to the new homeowner, with no re-registration required.

Once a licensed GWIN tech commissions and certifies your system, here's what stands behind it. The complete terms — including exclusions and the claim process — are on the warranty terms page.

The questions homeowners ask most about how GWIN's warranty works — start to finish.
Yes — once a licensed GWIN tech commissions and certifies your system, coverage attaches to your self-install. That's the key difference: most DIY mini split warranties void the moment a homeowner does the install, while GWIN's engages after a tech certifies the work.
The day after a licensed GWIN tech completes commissioning and certifies the system. Manufacturer defects and hidden shipping damage the tech finds are covered before that point, but full year-1 coverage on your install begins at certification.
No. Year-1 bumper-to-bumper labor and refrigerant coverage has no deductible.
Parts and compressor are covered for ten full years and shipped free. Year one adds bumper-to-bumper labor and refrigerant — including leaks the tech didn't catch at commissioning — on top of that.
If the compressor fails from a manufacturer defect within one year of commissioning and a licensed tech confirms it, GWIN ships a brand-new condenser and covers the labor to install and recommission it. After year one, the compressor is still covered as a part for the full ten years.
A leak the tech didn't catch at commissioning is covered under your year-1 refrigerant warranty. One note: if a leak is behind a wall or other non-exposed area, exposing and restoring it is the homeowner's responsibility — the repair itself is covered. Full details are on the warranty terms page.
Yes. Coverage follows the equipment and the original commissioning date, not the owner. Both the year-1 and 10-year terms transfer automatically to the new homeowner, with no re-registration required.
Customer installation errors, leaks caused by your installation, additional refrigerant before certification, damage from improper use or electrical/water issues, natural disasters, non-approved parts, and routine maintenance. The complete exclusions list is on the warranty terms page.
