Hvac Installation Services GST Rate for SAC Code 995463
HVAC and refrigeration installation services, including AC installation and cold room setup, are treated as works contract or construction related services under GST. Earlier, different ways of splitting equipment supply and installation sometimes created different effective tax outcomes for similar projects, which made quotation and tax planning difficult for contractors and clients.
After the September 2025 rationalisation, most HVAC and refrigeration installation services under SAC 995463 generally fall in the 18% slab with input tax credit. This standard rate applies where HVAC or cold room systems are supplied and installed as part of a works contract, unless a specific notification grants concessional treatment for a particular public or social sector scheme.
