The management system for companies that sell and install air conditioning.
Create quotes for air conditioners and heat pumps with models, accessories, compatibility checks and tax deductions. Use the home simulation to help customers understand where to place units and which capacity to choose.
More complete quotes, clearer choices
From a single split unit to systems with multiple indoor units, YumaOS helps you select components, check combinations and present proposals customers can understand.
A price that includes the accessories
Add air conditioners from your price list with model, capacity in BTU and pipework distance between indoor and outdoor units. Include brackets, access platforms, cranes, old equipment disposal and Wi-Fi modules.
Fewer mistakes with multiple units
Create quotes for single-split and dual, triple or four-unit multisplit systems, with compatible components listed first and alerts for missing units. Manufacturer-unsupported combinations are blocked unless you enter a reason, which stays on record.
VAT and tax deductions without manual calculations
YumaOS calculates mixed VAT at 10% and 22%, while the salesperson selects the tax deduction in the quote: 50% for a primary home or 36% for a second home. The invoice includes the correct bank transfer payment reference.
Fewer surprises before signing
Before the customer signs, YumaOS warns you if the selected combination is excluded from the 65% or 110% tax deductions or Italy's Conto Termico incentive. This helps you identify exclusions during the sales process.
A proposal that is easier to explain
Customers see a separate section for each installation position, showing the selected air conditioning units. The proposal link also includes the manufacturer's technical datasheets.
More solutions for your customers
Alongside split and multisplit systems, you can quote heat pump water heaters in a dedicated area. You can also add air-to-water heat pumps with fan coil units to your price list.
Help customers decide where to place air conditioners
Available on the Business plan, the illustrative home simulation shows the quoted air conditioning units in a 3D house, including two-storey layouts. Start with sample rooms or a computer-drawn floor plan in PDF format. To estimate capacity room by room, it uses local job-site weather data, the design day and the UNI EN ISO 15927-2 standard, with 26°C in summer and 20°C in winter. It is not a certified calculation.
Suggests the number, position and capacity of units, finding the lowest-cost multisplit solution.
Shows airflow, room temperatures, humidity and thermal views of walls, with condensation and mould warnings.
Measures refrigerant pipe runs in 3D to update the quote and shows customers the unit layout.
Know where every job stands after signing
Air conditioning jobs follow their own stages: technical site visit, ordering, warehouse, installation, inspection, ENEA filing and final documentation. From the signed quote, you can follow the job through to completion.

Yes. You can quote single-split and dual, triple or four-unit multisplit systems. YumaOS checks manufacturer combinations, alerts you to missing units and blocks unsupported configurations unless you enter a reason that remains on record.
YumaOS calculates VAT at 10% and 22% and lets the salesperson select a 50% deduction for a primary home or 36% for a second home. Before signing, it flags combinations excluded from the 65% and 110% deductions and Conto Termico, while invoices include the correct bank transfer reference.
No. It is an illustrative simulation available on the Business plan. It helps estimate how many units are needed, where to place them and their capacity, avoiding corners, windows and direct airflow onto beds or sofas. It also includes checks for electrical cable cross-section and minimum room area for R32 refrigerant.
Customers get a separate section for every installation position and manufacturer technical datasheets in the proposal link. With the home simulation, you can also show the unit floor plan in the summary, shared link and PDF, plus an explorable 3D view of the house.
