Text Small-Hello there! As a marketing manager in the SaaS industry, you might be looking for innovative ways to engage your audience. I bet generative AI has crossed your mind as an option for creating content. Well, let me share from my firsthand experience.
autarc launches cooling load calculator: Plan air conditioning systems and generate professional documentation in minutes
Berlin, July 2026 – autarc GmbH is expanding its planning software with the cooling load calculator, a new tool for rapid cooling load calculation designed for HVAC contractors, solar installers, and refrigeration technicians. The new module allows for the dimensioning of air conditioning systems, enabling users to plan systems and generate client-ready PDF reports in just a few minutes. This release comes at a time when demand for cooling solutions is rising significantly across many European regions due to persistent heatwaves.
Rising demand meets complex planning processes
During the summer months, an increasing number of specialist companies are receiving inquiries about retrofitting air conditioning systems. These requests frequently come from customers who have already installed a heat pump or photovoltaic system and now want to add cooling capabilities to their existing setup.
Many companies currently handle this planning using Excel spreadsheets or simplified rough estimates. This is time-consuming, hinders professional consultation, and delays the quote generation process.
"Every summer, we see the same pattern: customers who have already installed a heat pump or PV system suddenly become interested in air conditioning. At the same time, many companies lack the time to process these inquiries efficiently," says Etienne-Noel Krause, co-founder and CEO of autarc GmbH. "With the cooling load calculator, we are creating the fastest path from a customer inquiry to a professional plan, complete with a client-ready report—without the need for extra Excel spreadsheets and, in many cases, even without an additional on-site visit."
Cooling load calculation as part of an end-to-end workflow
The cooling load calculator is fully integrated into the autarc platform, complementing the existing workflow from lead capture to planning, quoting, and invoicing.
Key features include:
- Multiple room capture options: via LiDAR scan, AI-assisted floor plan reading, or manual floor plan drawing.
- Cooling load calculation based on building data such as postal code/location, year of construction, and U-values, as well as room-specific factors like orientation, window areas, and internal heat loads.
- Design of single and multi-split air conditioning systems with automatic equipment recommendations.
- Automatic generation of a client-ready PDF report.
The focus is deliberately not on highly detailed simulation, but on a fast, practical planning process tailored to the daily operations of installation businesses.
Benefits for various specialist trades
Heating contractors can reuse existing LiDAR scans from the heat load calculation, often saving an additional on-site visit.
Solar installers can plan air conditioning systems in direct conjunction with existing photovoltaic systems and increase the self-consumption of the generated solar power.
Refrigeration and air conditioning companies gain access to the autarc platform for the first time with the cooling load calculator and can fully digitize their processes.
