📝 About this app
The HVAC Quick Load is the one and only rule-of-thumb HVAC heating and cooling load application for the iPhone and iPad.
This app now includes the HVAC Equipment Locator. Click here for details: http://bit.ly/1yTq539
This app performs rule-of-thumb HVAC cooling and heating load calculations for many types of commercial, industrial, institutional, and residential buildings. It allows you to quickly calculate the total required cooling and heating loads (in BTU/hr or Tonnage) and air flows (CFM or L/s) by inputting just the building type, total square area and number of people.
You can email all of the inputs and results to any email address. In addition, the email includes an Excel spreadsheet attachment from which you can perform more extensive calculations.
The basis of the calculations for this utility come from various authoritative HVAC texts that list average cooling and heating load values per square foot for many building types.
All values can be displayed in English (IP) and Metric (SI) units.
The following is a sample of some of the types of buildings that can be modeled:
1. Cocktail Lounges, Bars, Taverns, Clubhouses
2. Computer Rooms
3. Dining Halls, Lunch Rooms, Cafeterias, Luncheonettes
4. Hospital Patient Rooms, Nursing Home Patient Rooms
5. Jails
6. Kitchens
7. Libraries, Museums
8. Malls, Shopping Centers
9. Medical/Dental Centers, Clinics, and Offices
10. Nightclubs
11. Offices, Commercial
12. ..... and many more
This app is great for use out in the field to quickly analyze the cooling and heating properties of a building. However, please note, that it is by no means a substitute for rigorous heating and cooling load calculations, and HVAC equipment and materials should not be selected based upon the results from this application.
We also offer the following additional HVAC applications for the iPhone and iPad:
1. HVAC Duct Sizer
2. HVAC Pipe Sizer – Gas Low Pressure
3. HVAC Pipe Sizer - Gas High Pressure
4. HVAC Pipe Sizer – Liquid
5. HVAC Pipe Sizer – Steam
6. Steam Tables
7. Psychrometric Plus

Customers like it since it shows that we are tech-savvy and I can tell them instantly what size …
★★★★★ Exceeds my expectations
At first I was skeptical about a load calc app on my iPhone, since it is often so complicated. However, this app is so easy to use and I compared it to more rigorous load calc apps, and amazingly it came within 10% of those calcs.
I like t…

★☆☆☆☆ Not for residential

Please give me a refund…
★☆☆☆☆ Garbage
Doesn't work as advertised. Calculations are wrong and the app is almost unusable.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
