Use this heat pump size calculator to determine the appropriate size heat pump you need for your space.
Heat Pump Size Calculator
Use this calculator to estimate the size of the heat pump you’ll need for your space.
How to Use the Calculator
Input the square footage of the area you want to heat or cool, the average ceiling height of the space, and the level of insulation of the building (on a scale from 1 to 10). Hit “Calculate” and you will receive the estimated BTUs (British Thermal Units) required for your heat pump.
How It Works
The calculator estimates the number of BTUs needed to heat or cool a space based on its volume and the quality of insulation. It assumes a base value of BTUs required per cubic feet and adjusts this value based on your insulation input, which can affect heat loss and gain.
Limitations
This calculator provides an estimate and does not account for every factor, such as windows, doors, and local climate. For an accurate assessment, consult with a heating and cooling professional.
