In this work, a technical and economic comparison of options for the technical design of an integrated heating and cooling system in the Yakutsk city was carried out. A qualitative and quantitative assessment of the socio-economic, modes and environmental effects of the operation of an integrated heating and cooling system was obtained. The discounted payback period was six years for the option of decentralized cooling with local installation of absorption chillers. The use of waste heat by absorption chillers in the production of cold can reduce electricity costs by up to 29% per month of total consumption and save up to 519 million rubles per year. The introduction of integrated heating and cooling technology can reduce CO2 emissions by up to 58 tons.
