HVAC Load Calculator

Our HVAC Load Calculator is a powerful and user-friendly tool designed to help you accurately determine the heating and cooling requirements of your space.

By simply inputting key data such as room dimensions, insulation levels, window types, occupancy, and local climate conditions, the calculator provides precise recommendations for the ideal HVAC system capacity.

Whether you're designing a new indoor grow facility, upgrading an office climate system, or planning residential comfort improvements, this tool ensures your HVAC selection promotes energy efficiency, optimal comfort, and long-term cost savings. Take the guesswork out of climate control and make informed decisions with our smart load calculation solution.


Disclaimer: The BTU and tonnage calculator is designed to provide you with a rough estimate to determine the size of air conditioner you need. You should not rely on this calculator to decide whether to purchase an air conditioner. If you need to perform detailed load calculations to determine the exact cooling load for your home, please contact our professional HVAC team. We would be happy to help you determine the right size air conditioner for your home.
