Warranty

Whose warranty it is

Every unit we sell carries the manufacturer's limited warranty from Costway. We pass that warranty through to you. We do not add a warranty of our own, and we do not shorten the manufacturer's.

How long

Coverage varies by model. Costway's published coverage is often 5–8 years on the compressor and often 5 years on parts, but the exact years for each SKU are printed on its product page under Warranty. Read that line before you buy. If it is unclear, ask us and we will check the manufacturer's listing.

What is covered

Defects in materials and workmanship in the unit itself, for the period and under the terms Costway publishes for that model. Costway's terms control; if this page and the manufacturer's document differ, the manufacturer's document wins.

What is not covered

• Labor, installation, and service calls. We do not provide or pay for labor, and we add no labor warranty.
• Refrigerant recovery, recharge, or line set work.
• Damage from improper installation, wrong voltage, undersized wiring, or a missing disconnect. Improper installation can void the manufacturer warranty entirely.
• Shipping damage. That is a DOA claim; see the Returns page.
• Storms, flooding, power surges, pests, or neglect.
• Normal wear: filters, remote batteries, cosmetic marks.
• Units bought secondhand or installed outside the US.

This list is a summary. The manufacturer's warranty document has the full terms.

How to make a claim

1. Keep your invoice from The Mini Split Shop. It is your proof of purchase, and the manufacturer will ask for it.
2. Register the warranty with Costway if the manufacturer requires it. That is your responsibility. Check the product page and the paperwork in the box.
3. Have the unit installed by an EPA Section 608 certified HVAC technician and keep the installer's invoice. A claim on a self-installed unit may be denied.
4. If something fails, contact us first. Email setpile@gmail.com with the order number, the MPN, the serial number (on the unit labels), a description of the fault, and photos or a short video.
5. We open the claim with the manufacturer or the supplier and relay what they need. Typical outcomes are a replacement part shipped to you or a replacement unit. Labor to swap the part is on you.

Claims move faster with a clear fault description, the serial number, and any error code on the indoor display. Questions before you buy: contact us.
