LG mini split systems offer efficient climate control solutions for homes and businesses, but understanding the warranty that protects your investment is equally important. LG typically provides a 10-year limited warranty on compressors and a 5-year limited warranty on parts for their mini split systems, though coverage varies by model and installation circumstances. This comprehensive guide explores the details of LG’s mini split warranty offerings, registration requirements, claim processes, and how they compare to competitors in the HVAC industry. Knowing your warranty coverage ensures you can maintain your system properly and access support when needed.
LG offers a tiered warranty structure for their mini split systems. The standard limited warranty includes 10 years of coverage for the compressor and 5 years for parts when properly registered within 60 days of installation. Without registration, the warranty defaults to a 5-year compressor and 1-year parts coverage. This warranty applies to original owners in residential applications under normal use conditions.
The compressor, often considered the heart of the system, receives the longest coverage period due to its critical function and higher replacement cost. Parts coverage includes electronic components, fans, motors, and other internal components that may fail during normal operation.
Labor is not typically covered under the standard warranty, meaning while replacement parts may be provided at no cost, you’ll likely pay for the technician’s time to diagnose and repair the system. Some authorized dealers may offer complementary labor warranties during the first year.
| Component | Registered Warranty | Unregistered Warranty |
|---|---|---|
| Compressor | 10 Years | 5 Years |
| Parts | 5 Years | 1 Year |
| Labor | Not Included | Not Included |
Commercial vs. Residential Warranty Differences
The warranty terms differ significantly between residential and commercial applications. For commercial installations, LG typically offers a 5-year compressor warranty and a 1-year parts warranty, regardless of registration status. This reduced coverage reflects the increased demands and duty cycles placed on units in commercial settings.
Multi-zone systems that serve both residential and commercial purposes may have specific warranty provisions based on the predominant use case. It’s essential to clarify these details with your dealer before purchase, as misclassification could affect warranty claims later.
Some commercial-grade LG mini split models may qualify for enhanced warranty terms when installed in light commercial applications such as small offices or retail spaces. These special provisions should be documented at the time of purchase.
LG Extended Warranty Options
Beyond the standard coverage, LG offers extended warranty plans through their dealers and authorized service providers. These extended plans can provide up to 12 years of additional coverage and often include labor costs that aren’t covered in the standard warranty. The pricing varies based on the model, coverage length, and specific terms.
Extended warranties typically must be purchased within a specific timeframe after installation—usually 90 days to one year. They’re particularly valuable for high-end models or installations in areas with extreme weather conditions that may stress system components.

| Extended Warranty Type | Additional Coverage | Approximate Cost Range | Includes Labor |
|---|---|---|---|
| Basic Extension | +2 Years | $100-$300 | No |
| Premium Coverage | +5 Years | $300-$600 | Yes |
| Comprehensive Plan | +10 Years | $500-$900 | Yes |
Third-party warranty providers sometimes offer alternative extended coverage plans. While these may seem cost-effective, using non-LG authorized warranty services could potentially void the remaining manufacturer warranty. Always verify a provider’s relationship with LG before purchasing additional coverage.
How to Register Your LG Mini Split Warranty
Registration is critical to securing the full warranty benefits. LG offers online warranty registration through their website at www.lghvac.com under the “Product Registration” section. You’ll need your model number, serial number, installation date, and installer information to complete the process.
The registration must be completed within 60 days of installation to qualify for the extended standard warranty terms. After this window closes, the warranty defaults to the shorter unregistered coverage periods.
Required Information for Registration
- Unit model and serial numbers (found on the specification label)
- Date of installation
- Installer company name and contact information
- Proof of purchase (receipt or invoice)
- Property address where the system is installed
- Your contact information as the owner
Retaining a confirmation of your warranty registration is recommended. This documentation can expedite any future warranty claims and confirm your coverage start date, which begins on the installation date rather than the purchase date.
Making an LG Mini Split Warranty Claim
When your system experiences issues, the warranty claim process involves specific steps to ensure prompt service. Start by contacting your installing dealer or any LG authorized service provider, who will diagnose the problem and determine if it’s covered under warranty. They’ll need your registration information and a description of the system’s behavior.
The technician will submit the warranty claim to LG on your behalf after diagnosing the issue. LG then reviews the claim and, if approved, provides the replacement parts directly to the service provider. This process typically takes 3-7 business days, though some common parts may be immediately available.
Documentation Needed for Claims
- Proof of warranty registration
- Original purchase receipt or invoice
- Maintenance records showing regular servicing
- Photos or videos of the issue (if applicable)
- Description of the problem and when it began
Keep in mind that even under warranty, you’ll likely be responsible for the diagnostic service call fee and labor costs unless you have an extended warranty that includes labor coverage. These charges typically range from $75-$200 per service call, depending on your location and the complexity of the diagnosis.
Common Issues Covered Under LG Mini Split Warranty
The warranty covers manufacturing defects and component failures during normal operation. Common covered issues include compressor failure, refrigerant leaks due to faulty components, circuit board malfunctions, motor failures, and sensor defects. These represent the majority of warranty claims for LG mini split systems.
Electronic control issues are particularly common warranty claims, including display malfunctions, communication problems between indoor and outdoor units, and temperature sensor failures. These typically fall under the parts warranty and are relatively straightforward to replace.

Fan motor problems, while less common, are also covered when they result from manufacturing defects rather than external factors. Signs include unusual noise, irregular operation, or complete failure to start.
What’s Not Covered by LG’s Mini Split Warranty
Understanding exclusions is equally important as knowing what’s covered. The warranty specifically excludes damage from improper installation, inadequate maintenance, power surges, corrosion from coastal environments, and damage from external factors like storms or accidents. These limitations are standard across most HVAC warranties.
Consumable components like air filters require regular replacement and aren’t covered under warranty. Similarly, cosmetic damage that doesn’t affect performance falls outside warranty coverage, including scratches, dents, or discoloration from sun exposure.
Common Warranty Exclusions
- Damage from improper installation or unlicensed installation
- Issues caused by failure to perform regular maintenance
- Damage from power fluctuations or improper power supply
- Corrosion in coastal areas (unless using coastal-rated models)
- Damage from natural disasters or accidents
- Normal wear and tear of components
- Refrigerant replacement after the initial charge
It’s worth noting that installation by non-certified technicians can void your warranty entirely. LG recommends installation by professionals certified in their products to ensure proper setup and continued warranty coverage.
Comparing LG Mini Split Warranty with Competitors
When evaluating mini split options, warranty comparisons can be a deciding factor. LG’s warranty terms are competitive but not necessarily the most generous in the industry. Here’s how they stack up against major competitors:
| Brand | Compressor Warranty | Parts Warranty | Labor Included | Registration Required |
|---|---|---|---|---|
| LG | 10 Years (registered) | 5 Years (registered) | No | Yes (60 days) |
| Mitsubishi | 12 Years (registered) | 12 Years (registered) | No | Yes (90 days) |
| Daikin | 12 Years (registered) | 12 Years (registered) | No | Yes (60 days) |
| Fujitsu | 10 Years (registered) | 10 Years (registered) | No | Yes (60 days) |
| Gree | 7 Years | 5 Years | No | No |
Mitsubishi and Daikin generally offer the most comprehensive coverage with 12-year terms for both compressors and parts when registered. Fujitsu matches LG’s compressor coverage but extends parts coverage to 10 years instead of 5. Gree offers less extensive coverage but doesn’t require registration.
The warranty value should be considered alongside system cost, efficiency ratings, and dealer support in your area. Some brands with longer warranties may have higher upfront costs or limited service networks in certain regions.
Maintaining Your LG Mini Split to Protect Warranty
Regular maintenance is not just recommended—it’s required to keep your warranty valid. LG’s warranty terms typically require proof of annual professional maintenance and regular owner maintenance like filter cleaning. Neglecting these requirements can result in denied warranty claims.
Professional maintenance should be performed at least annually by an authorized technician. This service typically includes checking refrigerant levels, cleaning coils, testing electrical components, and ensuring proper operation. Keep all maintenance receipts and records in a safe place.

Required Homeowner Maintenance
- Clean or replace air filters every 2-4 weeks during heavy use periods
- Keep outdoor units clear of debris, vegetation, and snow
- Clean indoor unit vents and louvers regularly
- Ensure proper drainage from condensate lines
- Visually inspect for any unusual operation or noises
Some LG models include self-diagnostic features that can alert you to potential issues before they cause major damage. Responding promptly to error codes can prevent more serious problems and demonstrate your commitment to proper system maintenance if warranty questions arise later.
Transferring LG Mini Split Warranty When Moving
If you sell your home, you may wonder about transferring the warranty to new owners. LG mini split warranties are generally transferable to subsequent homeowners, but the process requires documentation and notification to LG. This transferability can be a selling point when marketing your home.
The transfer process typically requires submitting a warranty transfer form along with proof of the property sale and system maintenance records. Some warranty aspects, particularly extended coverage purchased separately, may have different transfer terms or additional fees.
New homeowners should request all warranty documentation, registration confirmation, and maintenance records during the property transaction. Having this information readily available will simplify any future warranty claims and confirm the remaining coverage period.
Smart Home Integration and Warranty Implications
Many modern LG mini splits offer smart home integration through Wi-Fi connectivity and compatibility with systems like Google Home, Amazon Alexa, or Apple HomeKit. Using these features doesn’t void the warranty, but any third-party devices or software that modify the unit’s operation beyond manufacturer specifications might.
LG’s ThinQ technology allows for remote monitoring and control, which can actually help maintain warranty compliance by alerting you to maintenance needs or potential issues before they become serious problems. The app can also store your warranty information and maintenance schedule for easy reference.
When using smart home integration, stick to LG-approved connections and avoid unauthorized modifications to the control systems. Software updates provided by LG should be applied promptly to ensure proper operation and compatibility with connected devices.
