From site visit to completed climate control plan
Calculate cooling loads room by room instead of estimating with rules of thumb, select the right indoor and outdoor units, and generate reports and quotes in one go. No Excel, no manufacturer tools, and no external calculations required.
Cooling load, equipment selection, and quote in one go




Calculate cooling load by room
Instead of estimating with 100 W/m², calculate each room individually: window orientation and surface area, internal loads from people and equipment, plus an allowance for humidity. Design conditions are preset and can be adjusted, and you can override individual room values.
Unit selection and climate planning
autarc suggests the appropriate indoor unit size for each room and warns you if a unit is under- or oversized. You choose between single-split and multi-split, assign indoor and outdoor units, and place them directly on the floor plan.
Report and quote
Finally, generate the report as a PDF – including on-site documentation for condensate and power connections with photos. You can add the planned units to your quote with a single click, without having to enter them a second time.
