Heat load calculation is used to calculate the total cooling capacity of a piece of equipment. This information is used to determine the size and type of HVAC unit that is needed for a particular space.

### HVAC CFM Calculator, HVAC Labor Rate Calculator, HVAC Financing Calculator, HVAC EER Calculator

The HVAC CFM calculator can be used to determine your air conditioner efficiency and how much electricity you will need for it. The HVAC labor rate is the cost, in dollars per hour, of an HVAC professional doing the job. The HVAC Financing Calculator is used to calculate the cost of ownership based on estimated annual energy and utility usage. The HVAC EER Calculator is used to measure the efficiency of an HVAC unit.

### The Complete Guide of Basic HVAC formulas in excel - (Online HVAC heat load calculator)

In this article we will discuss some basic hvac formulas and equations. We will learn how to calculate the amount of air needed in a room and how to calculate the temperature, humidity levels and relative humidity inside a building. Many hvac formulas are shown in live excel

### Ohms Law

Ohm's law is a fundamental principle of electricity that states the current through a conductor between two points is directly proportional to the voltage across those points. This law is named after Georg Simon Ohm, who discovered it in 1827.

### Three Phase Motor Voltage Imbalance

When an imbalance exists in a three-phase motor, the largest imbalance will be divided by average volts to calculate a percentage

### Wattage Formula

The wattage formula is a calculation that can be used to determine how much power is needed for a task. It takes into account the voltage and current of an electrical circuit to calculate the wattage.
