In this article, we study the sensitivity of RES-NOVA, a novel cryogenic calorimetric experiment employing PbWO$_4$ crystals grown from archaeological lead, to neutrino non-standard interactions (NSI). We perform a sensitivity study for a benchmark setup with a nominal energy threshold of 1 keV and an exposure of 1 ton$\\cdot$y, both for a conservative (only heat readout) and ideal (heat and scintillation) background rejection scenario. We find that, in its nominal configuration, RES-NOVA can reach sensitivities to NSI at the level of current global fits. With moderate or significant improvements of the threshold down to 0.5 keV and 0.1 keV, RES-NOVA will be able to achieve sensitivities beyond NSI global fit results, testing new areas of the parameter space in the electron and tau sectors, $\\varepsilon_{ee}$, $\\varepsilon_{ττ}$, and $\\varepsilon_{eτ}$. A similar improvement in sensitivities is expected when instead increasing the exposure to 10 ton$\\cdot$y.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='hep-ph'/>\n    <published>2026-02-26T19:00:00Z</published>\n    <arxiv:primary_category term='hep-ph'/>\n    <author>\n      <name>D.
