HVAC Load Plus Mobile App for iOS

The HVAC Load Plus app for the iPhone was the first HVAC Manual J8 (abridged) load calculation mobile app for Apple iOS. See why Carrier, Trane, Mitsubishi Electric, JCI, and tens of thousands of engineers, technicians and architects have licensed our mobile software for their HVAC engineering needs. (Please note that this app is not ACCA-approved. It is based upon the abridged Manual J8 load calculations. For our ACCA-approved iPad app, click here.)

The HVAC Load Plus app is an HVAC load calculation software tool that allows you to perform heating and cooling loads for small commercial and residential buildings out in the field, by taking advantage of the simplicity and power of the iPhone:

  1. Create HVAC load calculations while at the work site
  2. Explain project details to your clients using advanced on-screen reports
  3. Email the results back to the office
Even better, save your projects for reference and further analysis. You can even use it as a template for new projects similar in scope - saving your company costly mistakes and virtually eliminating the time it takes to win new business and calculate loads for new projects.
