The temple priests perform the puja (rituals) during festivals and on a daily basis. As at other Vishnu temples of Tamil Nadu, the priests belong to the Vaishnavaite community, the Iyengars. The temple rituals are performed three times a day: Ushathkalam at 7:30 a.m., Uchikalam at 12:00 p.m. and Sayarakshai at 6:00 p.m.
Each ritual has three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Perumal and Thayar. During the last step of worship, nagaswaram (pipe instrument) and tavil (percussion instrument) are played, religious instructions in the Vedas (sacred text) are recited by priests, and worshippers prostrate themselves in front of the temple mast.

There are weekly, monthly and fortnightly rituals performed in the temple. The temples have Brahmotsavam (major festivals) in three subsequent months namely Panguni, Chittirai and Vaikasi. The Garuda Sevai function during the Tamil month of Vaikasi has assembly of 18 Garuda festive deities from 18 different temples.
The temples are revered in Naalayira Divya Prabandham, the 7th–9th century Vaishnava canon, by Thirumangai Alvar and Bhoothathalvar in one hymn each. The temple is classified as a Divya Desam, one of the 108 Vishnu temples that are mentioned in the book.
