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.

1

Set Up Your Workspace in Minutes

Create a company account, upload your logo and colors, and invite your team with role-based access.

Average setup time: 12 minutes.
2

Run Calculations and Export Reports

Pick a module, enter project parameters, and get an engineering-accurate result with a branded PDF.

PDF reports in under 3 seconds.
3

Share Access and Collaborate

Invite clients and partners into a white-label portal and keep a full history of every calculation.

White-label ready: your brand, not ours.

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

Steam absorption in the duct
AirflowSteam injectionAbsorption zone (Bn)Condensation-risk bandBn

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
