What is HVAC Load Calculation, And Why is It Important?

The mathematical process of measuring different aspects of a building to calculate the HVAC system's size, application, and style is called heat load calculation. The main purpose of heat load calculation is to ensure energy efficiency, save energy bills, and increase comfort inside the house.

What is an HVAC Load Calculation App?

The software application that helps in calculating the heating and cooling loads in the field while being installed on a smartphone is an HVAC load calculation application. This application will help calculate loads only in small commercial and residential buildings in a fast manner.

Top 7 HVAC Load Calculation Apps To Use Today

1. HVAC Load Plus

Finding the correct cooling and heating load is a chore, whether a small residential building or commercial property. The Caramel software company launched this super handy HVAC calculator app to aid the field workers in this matter.

It helps HVAC technicians calculate the correct heating and cooling block loads for any HVAC system. By entering the relevant details such as the location, number of rooms, windows, and building construction materials of the HVAC system, you can instantly get the load calculation results.

The biggest benefit of this top apps for hvac contractors are it allows you to create an unlimited number of projects.

This heat load calculation app contains the weather data of 100+ cities and data on structural components. Based on the included data, you can use this application for only small commercial or residential projects, as various factors should be considered for big properties.

Besides calculation, it lets you create graphs and pie charts and use them inside the progress report or work-related data for better understanding. You can also send the work report to your senior or other employees via email, making it super convenient for field workers. They don't need to wait for an in-person meeting to determine the ongoing problems.

Like others, this app is available in the app store and official website to be accessed directly, though it will charge you around $11.99 to avail of all premium features.

2. HVACR Check and Charge

Manual refrigerant charge calculation could lead you towards overcharging or undercharging and end up with a damaged HVAC system. Luckily, Emerson Climate Technologies launched an easy and efficient on-site refrigerant charge calculator for air conditioning and refrigeration applications.

With an easy-to-use interface, this calculator app determines the charge limit, indicates the depleted levels, and figures out the factors that have depleted the sufficient resources.

The application calculates airflow and targets superheat for fixed orifice expansion devices. For calculating the correct system charge, it requires some information, such as the system temperature with sensible and latent environmental loads.

This free-to-use handy tool just simplifies the jobs of HVAC workers, as well as enhances accuracy in the workflow. You can install this HVAC app on both iOS and Android smartphones.

3. Duct Calc Elite

Small ducts force the entire HVAC system to work more to keep the projected area cool or heated at the desired temperature; hence, the system could get damaged due to overload. Conversely, the big duct negatively affects velocity, restricting the system from providing the most out of it through the vents.

Calculating the proper duct size isn't a chore for those who use this handy Duct Calc Elite. It's one of the most efficient HVAC calculator apps you can rely upon without a second thought.

You will get the accurate measurement suggestion if you input the right information on the square footage of each room and the entire property, cubic feet per minute, and existing friction loss rate.

This app will let you enter this information with various units with an intuitive, user-friendly interface. It offers various unit options for elevation, velocity, airflow, air temperature, pressure loss, duct dimension, and input options for duct material.

Apart from these unit input options, it offers multiple calculation modes, like airflow mode, dimension mode, and pressure drop mode, to ease the calculation process and enhance the accuracy level. You can install this application on your iOS or Android smartphone.

4. HVAC Superheat Calculator

Measuring the exact superheat values on different temperature points is important to keep running the HVAC, specifically the air conditioning devices, efficiently and prevent damage from all possible HVAC issues.

As you know, small amounts of liquid could cause detrimental damage to the compressor of your HVAC system. But, you can ensure that the entire refrigerant entering the compressor is free of liquid with this super-handy HVAC Superheat calculator.

The application has a very easy-to-use interface; plus, you will get detailed instructions on using the app. You can also consider it one of the best HVAC troubleshooting apps. You may have noticed that most clients come with overheating issues. If you have this application on your mobile device, you can easily determine whether the excess heat is overheating or not and take steps accordingly.

5. Bluon HVAC

The Bluon HVAC is another great application that lets you accurately calculate the maximum heating and cooling loads for residential and commercial buildings. The best part of Bluon HVAC is it empowers the HVAC technicians with everything.

From accurate calculation tools to training on the usage, including 24/7 support, you will get everything you need to get the job done faster when you open the app.

Like other load calculation apps, it also helps you calculate the airflow, subcooling, and superheating loads just with a few clicks. In addition to that, you will get a nitrogen pressure test tool, which is missing in most HVAC load calculation apps.

Not all applications have included the environment-friendly R-22 alternative refrigerants, unlike Bluon HVAC. So, we suggest using only this HVAC load calculation app if you're going to take up a project based on environment-friendly cooling or heating devices.

If this application sounds interesting, then install it on your Android or iPhone now.

6. Hytools Calculator

HVAC engineers calculate heat load, airflow, and other complicated hydraulic calculations before designing air ducts. Thanks to the Hytools, that easily helps to measure every complicated thing, like pipe and valve sizing, radiator power and sizing, air pressure maintenance, pressure drop, and controls.

Moreover, the tool for making status reports and sending an e-mail enhances its utility in the HVAC field. I think there is no one who wouldn't like to have multiple features in a single application.

Conclusion

If the HVAC system is oversized for the house, it consumes more power, causes inefficiency, short-cycling, and fails to give the consistent temperature a properly sized system could give. Meanwhile, if the HVAC system is undersized, it is also a problem. Instead of short cycling, the HVAC system will have a long air conditioning cycle, which is again a problem.

Also, small-sized systems are prone to breakdowns, and constant maintenance is required to keep them from running optimally. So all these problems arise when you don't calculate the HVAC load for the house before installing the system.

Now that you've read the list of HVAC calculator apps, you can create estimate using hvac estimate template free of the heat load and pick the right sized HVAC systems for the house fast and efficiently.
