The Replacement Guide
Building a replacement system?
Our Replacement Guide walks you through building a replacement system in 5 easy steps:
1. Existing System
Input the details of your existing system, including:
- Existing equipment manufacturer
- Existing outdoor tonnage
- System orientation
- System direction
- Does the existing return adapter need replacing?
- Does the system have a heating coil?

Note: if we know the outdoor unit tonnage, the system will give us what we need. So we do ask which equipment model you’re replacing, but the important data for the app to capture is the outdoor tonnage
2. Replacement System
Enter the retails of your replacement system, including the new:
- Blower orientation
- Blower direction
- Outlet adapter

3. Replacement Summary
You'll then get a summary of all suggested replacement equipment for the new system.
4. Design Check
Check other aspects of the existing system to ensure the best compatibility.
You'll also get a calculation for the minimum number of outlets required.
Be sure to input and check each field for accuracy.
5. Overview
Here is where you'll get your material list for your new system that you can download as a pdf 
You'll also get a breakdown of specs for the old system and full list of specs for the new system.
