  In this paper, we initiate the study of conformal $\eta$-Ricci soliton and
almost conformal $\eta$-Ricci soliton within the framework of para-Sasakian
manifold. We prove that if para-Sasakian metric admits conformal $\eta$-Ricci
soliton, then the manifold is $\eta$-Einstein and either the soliton vector
field $V$ is Killing or it leaves $\phi$ invariant. Here, we have shown the
characteristics of the soliton vector field $V$ and scalar curvature when the
manifold admitting conformal $\eta$-Ricci soliton and vector field is pointwise
collinear with the characteristic vector field $\xi$. Next, we show that a
para-Sasakian metric endowed an almost conformal $\eta$-Ricci soliton is
$\eta$-Einstein metric if the soliton vector field $V$ is an infnitesimal
contact transformation. We have also displayed that the manifold is Einstein if
it represents a gradient almost conformal $\eta$-Ricci soliton. We have
developed an example to display the alive of conformal $\eta$-Ricci soliton on
3-dimensional para-Sasakian manifold.
