The Rheem Calcu Save mobile app provides on-the-go access for contractors to calculate cost savings for homeowners by comparing residential HVAC system replacement options.

Made of the good stuff:

The Rheem Calcu Save app uses Emerson Climate Technologies Online Product Information (OPI) database for Rheem Heating & Cooling products to give contractors the ability to generate reliable, accurate, graphical reports.

Beautiful reports, in 3 easy steps:
1. Enter in a few parameters relevant to the specific residential HVAC task, such as current system efficiency standards and their considered replacement options.
2. After the details of the job are entered into the app, the app generates a professional-looking report that shows annual cost savings of high efficiency systems.
3. Email your customers or even yourself a copy of the reports generated.

More than meets the eye:

The Rheem Calcu Save app offers up to three replacement system options, which are also compared with current industry minimum standards, for the contractor and the homeowner. This will allow homeowners to more easily choose a replacement HVAC system to meet their particular needs.
