Problem
Sound Familiar?
HVAC engineering teams lose weeks every year to tooling that was never built for them.
There is a better way.
Onboarding
Up and Running in Three Steps
No IT department needed. Your first calculator can go live in a single afternoon.
Set Up Your Workspace in Minutes
Create a company account, upload your logo and colors, and invite your team with role-based access.
Run Calculations and Export Reports
Pick a module, enter project parameters, and get an engineering-accurate result with a branded PDF.
Share Access and Collaborate
Invite clients and partners into a white-label portal and keep a full history of every calculation.
Modules
Built for Every HVAC Calculation Your Team Faces
Purpose-built modules with engineering accuracy validated against industry standards.

Use Cases
How HVAC Teams Use ClimaHub
Industrial Humidifier Manufacturer
Challenge
Sales engineers spent 3–5 hours preparing each quote by hand.
Solution
Humidifier Selection deployed as a white-label portal for the whole sales channel.
Outcomes
- Quote time: 4 h → 25 min
- 3× more quotes per week
- Distributors independent from support
Regional HVAC Distributor
Challenge
Every branch used its own Excel formulas, causing discrepancies and warranty risk.
Solution
Branches standardized on centralized, versioned modules.
Outcomes
- Zero formula discrepancies
- 2,400+ calculations in one archive
- New engineer onboards in 1 day
MEP Engineering Consultancy
Challenge
Calculations lived on laptops with no audit trail and no versioning.
Solution
Migration into shared projects with defined roles.
Outcomes
- Full audit trail
- 8 engineers in one workspace
- Reports stay fully branded
“Before ClimaHub, only one engineer could run proper humidifier selections. Now the whole sales team completes calculations in under 30 minutes.”

Platform Depth
More Than a Calculator Platform
ClimaHub unifies calculation logic, project workflows, branded reporting, and managed collaboration in one environment — instead of scattered files and isolated expertise.
Growth
A Growing Platform, Not a Fixed Toolset
A managed, expandable library — controlled by the manufacturer, localized for each market, and scaled without fragmentation.
Enablement
From Legacy Software to Cloud Infrastructure
We rescue engineering methodology from technical debt, build new modules from scratch, and use AI to accelerate — not to replace expertise.
Engineering Proof
What Our Engine Actually Calculates
We don’t just size equipment by capacity. Our engine computes the physical steam-absorption zone in the duct — accounting for channel geometry, obstacles, flow direction, and condensation risk in a single calculation.
What the engine accounts for
- Base absorption-zone calculation
- Cross-check between tabular and analytical methods
- Obstacle influence coefficients: bend, narrowing, expansion, diffuser, branch, filter, fan
- Flow direction
- Configuration-specific limitations
- Condensation-risk analysis by dew point
- ASHRAE methodology
- Barometric pressure for the specific city
- Climate data from NASA POWER / MERRA-2
