How often does an air conditioner require service?

Are service checks mandatory?

To know if your air conditioner must adhere to compulsory service checks, you first need to see how much refrigerant the unit can hold. If the unit contains less than three kilograms of coolant, maintenance is not required. If your air conditioner holds more, then the following rules apply: 

• 5 TCO2 of coolant: annual maintenance is required 

• 50 TCO2 refrigerant: the unit requires a service check every six months 

• 500 TCO2 refrigerant: the unit requires a service check every three months 

How do you know if an air conditioner needs maintenance? 

Although you are not required to perform regular maintenance checks, it is sometimes necessary. Even without noticeable defects, we recommend getting an air conditioner checked at least once a year to ensure it’s performing at its best. Here are the signs to be on the lookout for that may indicate an air conditioner needs immediate maintenance. 

• If your unit makes more noise than usual, the filters may be clogged. Clean the unit by removing dust with a vacuum cleaner. If the same noise persists, or you hear a chatter or rumble sound, there could be a mechanical issue. 

• If it takes an air conditioner takes longer to cool a room, then the coolant level is too low. 

• If you see higher energy costs from your air conditioner, that could mean the unit is not installed correctly and needs to be checked.
