Quick answer
A warranty comes free with the product and covers manufacturing defects for a fixed period. An extended warranty is a paid add-on that stretches defect cover beyond that period. An AMC is a paid yearly maintenance contract that covers routine servicing and breakdown support — not just defects — and can be taken from the brand or an independent service provider.

|---|---|---|---|
| Cost | Included in product price | Paid extra | Paid yearly |
| Provided by | Manufacturer | Manufacturer, retailer or third party | Brand service network or independent provider |
| Covers | Manufacturing defects | Defects, after standard warranty | Routine servicing and breakdowns |
| Preventive servicing | Usually not included | Usually not included | Core part of the contract |
| Spare parts | Defective parts replaced | Defective parts replaced, as per terms | Depends on type — comprehensive or not |
| When it applies | From purchase | After standard warranty ends | Any time, typically after warranty |
| Renewable? | No | Usually fixed term | Yes, yearly |
Warranty
The manufacturer's promise that the product is free of defects in material and workmanship for a stated period. If something fails because of a defect, the brand repairs or replaces it.
What a warranty typically does not cover: wear and tear, damage from misuse or power issues, installation problems, and routine servicing like cleaning filters or coils. Many people assume "under warranty" means free servicing — it usually does not.
Extended warranty
An extended warranty is bought separately, often at the time of purchase, and continues defect cover after the standard warranty ends. Terms vary widely: some cover only specific parts, some have claim limits, and some are sold by third parties rather than the brand.
It is still defect cover. It usually does not include regular maintenance visits.
AMC
An Annual Maintenance Contract is a service agreement, not defect cover. The provider commits to a set number of preventive visits plus breakdown support for the year. In a comprehensive AMC, most parts are covered too; in a non-comprehensive AMC, parts are charged separately.
The big difference: an AMC keeps the equipment serviced. Warranties only respond after something has failed. For a full introduction, see What Is AMC?
How they fit over the equipment's life
| Stage | What usually applies |
|---|---|
| Purchase to end of standard warranty | Warranty for defects. Servicing may be paid separately, or covered if an AMC is taken. |
| After standard warranty, if extended | Extended warranty for defects, as per its terms. |
| After all warranties end | AMC for servicing and breakdowns, renewed each year. |
An AMC can also run alongside a warranty. Some customers take one during the warranty period purely for scheduled servicing.
Which should a customer choose?
- New equipment: the standard warranty covers defects. Consider an AMC if regular servicing matters, such as for commercial ACs or RO plants.
- Expensive, high-risk parts: an extended warranty may make sense, but read the claim terms closely.
- Equipment out of warranty: an AMC is the usual choice for ongoing care.
- Several units, or business-critical equipment: an AMC with clear response terms gives the most control.
Common points of confusion
- "Extended warranty from the shop is the same as the brand's." Not necessarily. Third-party plans have their own claim process and exclusions.
- "Any repair keeps my warranty valid." Some warranty terms say unauthorised repairs can affect cover. Customers should check their terms before calling an outside technician during warranty.
- "An AMC covers everything." Only a comprehensive AMC covers most parts, and even then with exclusions.
- "Warranty and AMC cannot overlap." They can. The AMC handles servicing; the warranty handles defects.
For service providers: the warranty-end moment
The month a product leaves warranty is one of the best times to offer an AMC. If you install or repair equipment, note the warranty end date when you add the unit, and plan a friendly message before it lapses. More ideas in turning repair customers into AMC customers.
Whether you serve home appliances, ACs or RO purifiers, tracking contracts per unit is what AMC software is built for. See how our AMC management software works.
How AMCFlow helps
- Add customers and each of their units, and record an AMC per unit with its start and end dates.
- Log complaints against the AMC, so covered and chargeable visits are easy to tell apart.
- Assign complaints to technicians with a WhatsApp job alert carrying customer, mobile, address, product, problem and complaint number.
- Expiry dashboard showing AMCs nearing expiry.
Frequently asked questions
What is the difference between warranty and AMC?
A warranty comes free with the product and covers manufacturing defects. An AMC is a paid yearly contract that covers routine servicing and breakdown support.
Is an extended warranty the same as an AMC?
No. An extended warranty continues defect cover after the standard warranty ends. An AMC is a maintenance contract with scheduled servicing and breakdown visits.
Does a warranty include free servicing?
Usually not. Most warranties cover defects only. Routine servicing such as cleaning and inspection is typically charged separately unless an AMC or a specific service offer applies.
Can I take an AMC while my product is under warranty?
Yes. Some customers take an AMC during the warranty period for scheduled servicing, while defects continue to be handled under the warranty.
Which is better, extended warranty or AMC?
It depends on the need. An extended warranty suits customers worried about expensive defects. An AMC suits customers who want regular servicing and breakdown support every year.
