Importance of Regular AC Service

  • Increase Efficiency and Performance

To optimize the efficiency and performance of any air conditioner, regular service plays crucial role to achieve it. Over the time we use the air conditioner, the dust particles, debris, and many other particles in the air conditioner affect the ability to provide cooling efficiently. So it is important to have routine maintenance that includes regular cleaning and inspecting its components for any kind of damage or wear and tear. This kind of care and maintenance minimizes the strain on the system.

Factors Responsible for AC Service Frequency

Following are the factors that influence the frequency of service.

  • Climate and Usage Pattern

The local climate plays a very important role in deciding the frequency of service of an air conditioner. The another factor is the frequency of AC usage, It also plays a very important role in determining the interval of service. All the regions where we have a harsher climate or AC used extensively, require more frequent services than regular areas.

  • Manufacturer Recommendations

Almost all the manufacturers of the air conditioner provide the manual and guidelines for recommended service frequency for their particular model. This is the first step from where you can get to know the maintenance and service frequency.

  • Age of the Air Conditioner

The age of the air conditioner also decides the frequency of the service. Older AC requires more maintenance and service because their components are very susceptible to wear and tear. Getting them to operate optimally, requires more service.

Recommended Service Intervals (How often should you service your AC?)

  • Annual

As per the general guidelines, it is recommended to have at least one service every year. This yearly maintenance includes proper inspection, cleaning of all the components, lubrication, and evaluating the performance of an air conditioner.
