The building material of the church is brick, which is unusual for its construction period.
Hjärsås Church is the only church in the province of Skåne which retains traces of paint on the facade from decorations made in historical times.
The south walls of the nave and choir, as well as the apse, are decorated with ornamental paintings.
It is not known when these were made; they might date from the Middle Ages or the 16th century, but they may also be of later date.
They were restored in 1939.

Inside, the vaults of the choir and apse are decorated with murals made in the early 16th century and probably no later than 1510.
Stylistically these differ from any other medieval murals in the province.
They depict similarities to decorations in the church of Mary Magdalene in Djursland, Jutland, as well as those in Nørre Herlev, Zealand and may have been made by either one of the artists decorating these churches.
The subjects depicted are visions of Heaven and Hell, including the Last Judgment, and the Trinity with Mary.
The depictions show a throng of people and beasts in the narrow space of the vaults.

The pulpit of the church was bought in 1593 and was made by artisan Daniel Thomissen in Malmö.
The larger of the two church bells dates from 1703, and the smaller one from 1748.
The still present furniture of the sacristy was donated by a priest to the church in 1735.
During the 19th century, a new altarpiece was installed (1840).
In 1888 the church organ was installed and the pulpit repainted.
