HVAC Calculators
Explore our collection of essential HVAC calculators designed to help contractors quickly and accurately calculate airflow, load, duct size, and more. These tools streamline complex calculations, ensuring efficient system design and optimal performance for every project.
ACH Calculator
The ACH (Air Changes per Hour) Calculator helps HVAC contractors determine how many times the air in a room is replaced each hour.
Air Flow Rate Calculator
The Air Flow Rate helps calculate the flow rate of air moving through a duct or pipe based on its diameter and the velocity of the air.
BTU Calculator
The BTU Calculator estimates the heating or cooling needed for a space by calculating the required British Thermal Units (BTUs).
CFM Calculator
Calculate the required airflow (CFM) for proper ventilation by entering room dimensions and air changes per hour (ACH).
Duct Calculator
The Duct Calculator helps HVAC contractors determine the optimal duct size based on airflow and velocity.
Parts Markup Calculator
The Parts Markup Calculator helps HVAC contractors quickly calculate the optimal selling price for parts.
Pipe Volume Calculator
The Pipe Volume Calculator helps HVAC contractors calculate the volume of a pipe based on its diameter and length.
Line Charge Calculator
This Calculator determines the correct refrigerant charge needed for a system based on the length and size of the refrigerant lines.
Water Velocity Calculator
This Calculator helps determine the speed of water flowing through a pipe based on the pipe's diameter and flow rate
