How Air Conditioner Warranties Work
Every air conditioner sold at Air Conditioners Shop is covered by a manufacturer’s warranty — a guarantee provided directly by the brand (LG, Frigidaire, Mitsubishi, etc.) that the product will be free from defects in materials and workmanship for a stated period of time.
Air Conditioners Shop is an authorized retailer. This means your warranty is fully valid when purchasing from us — the same coverage you’d receive buying directly from the brand or from a big-box retailer.
If your AC unit develops a defect covered by the warranty, the manufacturer will repair or replace the unit at no cost to you. Some warranties cover parts only; others cover parts and labor. The scope and duration vary by brand and product type.
Important: Warranty claims are handled directly with the manufacturer — not through Air Conditioners Shop. We are happy to help you locate manufacturer contact information and navigate the process, but we are not a service center and cannot authorize warranty repairs ourselves.
Warranty Coverage by Brand
The table below reflects the standard warranty periods for new units purchased from authorized retailers. Some brands offer extended coverage when you register your product online within 30 days of purchase.
| Brand | Product Type | Parts Warranty | Compressor Warranty | Labor Warranty |
|---|---|---|---|---|
| LG | Window AC | 1 year | 5 years | 1 year |
| Frigidaire | Window / Portable AC | 1 year | 5 years | 1 year |
| GE Appliances | Window AC | 1 year | 5 years | 1 year |
| Midea | Window / Portable AC | 1 year | 5 years | 1 year |
| Mitsubishi Electric | Mini Split | 5 years | 7 yrs (12 w/ reg.) | 1 year |
| Daikin | Mini Split | 5 years | 7 yrs (12 w/ reg.) | 1 year |
| Carrier | Central AC / Mini Split | 5 years | 10 years w/ reg. | 1 year |
| Goodman | Central AC | 10 years | 10 years | Not included |
| Hisense | Window / Portable AC | 1 year | 5 years | 1 year |
Warranty terms are subject to change by the manufacturer. Always refer to the warranty documentation included with your product for the most current terms. “w/ reg.” = extended period available with product registration.
What’s Covered vs. What’s Not
✓ Generally Covered
- Manufacturing defects in parts and materials
- Compressor failure under normal use
- Electrical component failures
- Fan motor defects
- Refrigerant leaks due to defective parts
- Control board failures
- Sealed system failures
✗ Generally Not Covered
- Physical damage from misuse or accidents

- Normal wear and tear
- Clogged or dirty filters (user maintenance)
- Damage from power surges or lightning
- Unauthorized modifications or repairs
- Commercial use of residential units
The exact coverage varies by manufacturer. Always read the warranty card included with your product for the specific terms applicable to your unit.
What Can Void Your Warranty
Certain actions can void your manufacturer’s warranty entirely. The most common causes of warranty voidance are:
- DIY installation of mini splits or central AC — Most manufacturers require installation by a licensed HVAC technician for systems requiring refrigerant line connections. Self-installation typically voids the warranty on these units.
- Using an unauthorized service provider — Having your unit serviced or repaired by someone who is not a manufacturer-authorized technician.
- Removing or altering the serial number — The serial number is required to validate your warranty claim. Never remove or deface it.
- Using non-approved refrigerants — Only the refrigerant type specified in the manual should be used.
- Commercial use of residential units — Running a residential-rated unit in a commercial environment (24/7 operation, non-residential settings) typically voids coverage.
- Physical damage — Dropping, crushing, or otherwise physically damaging the unit.
Window and portable AC units are generally safe to install yourself — these units do not require professional installation and self-installation does not void the warranty. Only mini split and central AC systems carry professional installation requirements.
How to File a Warranty Claim
Warranty claims are filed directly with the manufacturer. Here is the general process:
Gather Your Information
Locate your model number and serial number (on the label on the back or side of the unit) and your proof of purchase (order confirmation email from Air Conditioners Shop).
Contact the Manufacturer
Use the warranty contact information in your product manual or see the Brand Warranty Contacts section below. Most manufacturers have online claim portals and phone support.
Describe the Problem
Clearly describe the defect, when it appeared, and any error codes the unit is displaying. Photos or video of the issue can speed up the process significantly.
Schedule a Service Visit or Return
Depending on the product and defect, the manufacturer will either dispatch a service technician, send replacement parts, or authorize a return of the unit for replacement or repair.

Product Registration — Why It Matters
Many manufacturers offer significantly extended warranty coverage — sometimes double the standard period — when you register your product online within 30–90 days of purchase. This is especially important for mini split systems where Mitsubishi and Daikin extend compressor warranties from 7 years to 12 years with registration.
To register your product, visit the manufacturer’s website (listed in the Brand Contacts section below) and follow their registration process. You’ll need your model number, serial number, and date of purchase.
Register immediately after installation. Most extended warranty offers require registration within 60–90 days of the original purchase date. Don’t wait — set a reminder today.
