For the air conditioning and sanitation construction industry: Simplifying complex estimates accurately.

From updating air conditioning equipment to large-scale renovations. Easily create unit price calculations for equipment by manufacturer, as well as duct and insulation work calculations, to increase order rates.

Estimates for air conditioning and sanitation work involve a wide range of considerations, including the selection of equipment (outdoor and indoor units), refrigerant pipes, drain pipes, ducts, insulation work, and the amount of refrigerant to be charged. Using handwritten notes or Excel can easily lead to calculation errors and omissions, which can result in profit pressure. "Koujiyasan" encompasses all the necessary unit cost data and material masters for air conditioning and sanitation work. It allows for flexible registration of equipment and associated work as a set, as well as adjustments to the rates based on the scale of the project. We can also respond immediately to sudden requests for estimate revisions from the main contractor or proposals for cost reductions (VE proposals) by utilizing past data. Fast and accurate estimate submissions are key to gaining trust and increasing order rates. Would you like to start experiencing a dramatic change in the speed of estimating air conditioning work?
