Estimation App Cost


The HVAC Toolkit app for the iPhone and iPad is the essential app for anyone in the HVAC industry. It includes a combination of many of our stand-alone iOS applications. Individually, the apps cost a total of $70. By purchasing the Toolkit, you pay only $24:

1. HVAC Equipment Locator
2. HVAC PT Chart
3. HVAC Refrigerant Charge
4. HVAC Duct Sizer
5. HVAC Quick Load
6. Psychrometrics
7. Steam Tables
8. Pipe Sizer - Liquid
9. Pipe Sizer - Steam
10. Pipe Sizer - Gas High
11. Pipe Sizer - Gas Low

This is a universal app that works on both the iPhone and iPad.

The "HVAC Equipment Locator" module allows you to track, share, and customize your equipment nameplate and maintenance data. The version here includes the ability to customize your input screens.

The "HVAC PT Chart" module allows you to easily view the pressure-temperature properties of 75 refrigerants. Think of this app as a digital version of the paper PT charts that you may have carried around with you in the past.

The "HVAC Refrigerant Charge" module allows you to perform superheat and subcool refrigerant charge calculations on-the-fly. This app includes pressure-temperature data for over 75 common refrigerants.

The "HVAC Duct Sizer" module allows you to quickly size one HVAC duct run and a range of duct sizes. You can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters).

The "HVAC Quick Load" module allows you to perform quick and simple HVAC cooling and heating load calculation analysis. You can specify the building type, total area, and # of people. The results include the total cooling and heating loads and airflows.

The "Psychrometrics" module allows you to easily perform single-state and mixed-air HVAC psychrometric calculations for a wide range of barometric air pressures.

The "Steam Tables" module allows you to calculate the properties of saturated or superheated steam by specifying 2 input properties.

The "HVAC Pipe Sizer - Liquid" module allows you to size a pipe run with many different types of liquids (or fluids), pipe material and fitting types.

The "HVAC Pipe Sizer - Steam" module allows you to size a steam pipe run, and it also includes a bonus steam table calculator.

The "HVAC Pipe Sizer - Gas High/Low" module allows you to quickly size a simple low (less than or equal to 1.5 psi) and high (greater than 1.5 psi) pressure gas piping system by inputting a number of piping and gas properties.

This application includes all of the great features of the individual HVAC iOS applications such as the use of slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. It also allows you to specify different types of liquids, gases, pipe material types, fitting quantities, min and max ranges, and step values.

All of the above modules display units in English or Metric.

Also, all of the above modules allow you to send emails with inputs and results.

The "HVAC Toolkit" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. In addition, Carmel has developed customized apps for organizations such as ASHRAE, Mitsubishi Electric, and Pacific Gas and Electric, amongst others.

We also offer all of the above modules as individual apps for the iPhone/iPad:

1. HVAC ResLoad-J
2. HVAC Psych HD
3. HVAC Duct Sizer
4. HVAC Pipe Sizers
5. Steam Tables
6. Psychrometric Plus
7. Psychrometric LT
8. HVAC Pipe Sizer Plus
9. HVAC Pipe Sizer Gas Plus
10. HVAC Quick Load
11. HVAC Load Plus
12. HVAC Residential Load Calcs
13. HVAC Toolkit Ultimate
14. HVAC ASHRAE 62.1
15. HVAC ResVent 62.2
16. HVAC ASHRAE DFDB
17. HVAC ASHRAE Psych Chart

Well Done

I like the toolkit. Its quite useful for the HVAC engineer cause its possible to use SI-Units. But please add an PT-properties for refrigerants module. And also make these properties available in the pipe size modules to earn the fifth star.

Really a good app

A good application useful to do fast calculations "on the run" without need of charts. Some minor bugs have been fixed in the later release. Excellent communication with the developing team for further improvements.

HVAC Psychrometric bug

The calculation of enthalpy in SI unit not correct. Example: Dry-bulb temperature +25°C, relative humidity 50%, the enthalpy is 50,3 kJ/kg and not 68,15 kJ/kg. Please fix the bug, thank you.

Quite unique and clever

I love the Toolkit. I was thinking of buying all of the individual apps like duct sizer, pipe sizer, and psych. But, I decided to just buy the Toolkit which includes all of these apps and more like steam tables. I really can use it for all my basic HVAC engineering needs. Great job.

All in one HVAC calcs

This app contains almost everything I need for my hvac business: duct sizing, pipe sizing, quick load calcs, psychrometrics. I did some comparisons to my desktop programs, and the results look good. Now, heres my wishlist: 1. Add simple cost estimating 2. More detailed load calcs 3. Allow me to email results 4. english/metric conversions (I know there are tons out there, but itd be nice to have it in this app) Great work!!!

Great App!

This is a must-have toolkit for HVAC engineers. The program keeps getting better with each and every update. The developer has been very responsive and has even added some of my suggestions. Thanks again for making this program. I use it daily.

Lots of functionality

I really like this HVAC app. It has most the functionality that I need out in the field for sizing duct, pipes, doing quick loads, psych calcs, and other stuff. It looks pretty accurate after doing some comparisons back at the office. Id like to see some email functionality added to it. Also, how about adding the HVAC Load Plus function, too.
