How to calculate condensate production

This calculator estimates condensate production from an HVAC system by multiplying relevant load and humidity factors — useful for sizing condensate drain lines and pumps.

How the calculation works

Condensate production = Cooling load factor × Humidity/moisture factor (specific formula depends on your reference method).

Example

A base condensate rate of 2 gallons/hour with a 1.3 humidity adjustment factor for high-humidity conditions: Condensate production = 2 × 1.3 = 2.6 gallons/hour.

Frequently asked questions

How is Result calculated?

Result = [Condensate rate] × [Runtime].

Is the Condensate Production free to use?

Yes — every calculator on Simple Calculator Tools is free, runs in your browser, and does not require an account.

Pro Tips for Condensate Production

  1. Condensate production varies significantly with indoor humidity and cooling load — size drain lines and pumps for peak, not average, conditions.
  2. Check manufacturer specs for your specific equipment's typical condensate output rather than relying solely on a generic estimate.

Common Condensate Production Mistakes to Avoid

  • Sizing condensate drainage for average conditions rather than peak humidity/load conditions, risking overflow during the most demanding periods.
