The operation of air conditioners (air conditioning) requires reliability, especially in hot summers or cold winters. At the same time, air conditioners are subject to wear and tear and breakdowns. Manufacturers and importers therefore usually offer a warranty on various parts, but this air conditioning warranty is only valid if certain conditions are met.
In the following overview, we'll explain what is covered by the air conditioning warranty, what conditions apply, why maintenance is key - and give you some examples of warranty schemes from well-known brands.

Warranty and guarantee: basic concepts
- Any air conditioning system in Hungary at least 1 year warranty must be undertaken by law.
- In addition, under the Civil Code 2 years product warranty (3 years in total, if all conditions are met).
- However, many importers or brands voluntarily undertake extended warranty, which can be up to 5, 7 or 10 years for certain parts - but usually with conditions (e.g. compulsory maintenance).
So when buying an air conditioner, it's always worth reading the manufacturer's warranty conditions - they can often be stricter than the legal minimum.
What is covered by the air conditioning warranty?
The warranty typically covers failures due to manufacturing defects or defects in materials, not normal wear and tear or damage resulting from misuse. Typical warranty cases include:
- Compressor failure due to a manufacturing defect
- Electronic control panel faults
- Refrigerant leakage, if not due to installation or misuse
- Failure of fan motors (indoor and outdoor)
- Other key parts if there is a material defect or a manufacturing defect
The air conditioning warranty does not normally cover:
- Normal wear and tear (e.g. wear of filters)
- Problems due to lack of maintenance
- Damage resulting from incorrect or unprofessional installation
- Damage caused by storms, hail or other external environmental influences
This is why it is important that the conditions of the guarantee, such as compulsory maintenance, are strictly respected.
Why is regular maintenance compulsory for the warranty to be valid?
Many brands and importers require that maintenance at least twice a year be carried out by a professional. The aim is to:
- Cleaning the appliance: cleaning the indoor and outdoor units, heat exchangers and filters from dust and dirt - reducing energy consumption and increasing efficiency
- Checking the condition of the refrigerant and refilling if necessary
- Examination of system operating parameters (pressure, current consumption, software faults, sensors)
- Documentation: a record of maintenance must be kept and presented when the guarantee is invoked
If maintenance is not carried out - for example, if there is no record of it, or if it is not done professionally - the air conditioning warranty is often cancelled or the repair is refused.
Other things to consider: it is advisable to carry out maintenance before the season (e.g. in spring or autumn), so that the air conditioner can operate without any faults during peak periods.
