How it works
From the first attic photo to the report on the kitchen table.
A RhoeFlow assessment follows the way a good comfort advisor already works a house: look, measure, ask, calculate, then explain. The app keeps track of where every number came from so the result holds up when a homeowner, GC or inspector asks.

01 · On the phoneStart the assessment
Open the job from WorkEdge Pro or start one in RhoeFlow. Enter the address and the app pre-fills year built, square footage and orientation from the county record. Pick a home template for the era and style, and its construction defaults load in, each one tagged defaulted with its source.
✓Templates: 1940s brick, 1960s ranch, 1980s brick, 2010s multistory townhome, extendable by region
✓Job, customer and property stay in WorkEdge; RhoeFlow only stores the engineering

02 · On the phoneWalk the house
Go room by room. Photograph windows, walls, the attic, ducts, the air handler and the condenser, and dictate notes as you go. The app reads what it can from the photos (window type and count, duct condition, insulation depth) and proposes an answer. You accept it, correct it, or mark it unknown.
✓Every photo is filed to the WorkEdge job and linked to the input it supports
✓Short on time? The 12-question quick pass covers the inputs that move the load most
03 · On the phoneCalculate the block load
The calculation engine runs the cooling and heating load on the spot, with a component breakdown (walls, windows, ceiling, infiltration, ducts, people, appliances). A square-feet-per-ton gauge flags results outside the bands seen on real Texas installs. Inputs still marked unknown widen the result into a range instead of being treated as zero.
✓Each run is frozen with its inputs, method version and engine version
✓Re-open a run years later and get the same number

04 · Phone or desktopModel upgrades and choose equipment
Toggle duct sealing, attic insulation, new windows, air sealing, spray foam or a radiant barrier and see each change the load, alone and combined. Then match equipment to the load using manufacturer performance data at your design conditions, not just nominal tonnage.
✓Show the homeowner how an envelope upgrade can mean smaller, cheaper equipment
05 · On the desktopDesign the ducts
Back at the office, lay out the system on the floor plan. Draw by hand with drop-in supplies, returns, wyes, trunks and duct types, or trace over an uploaded blueprint. RhoeFlow sizes each run from room airflow and available static pressure and shows the result as a schematic for the engineering and a floor view for the crew.
✓The house map is saved, so the design can be updated on the next visit

06 · In front of the customerPresent the work
Generate a printable homeowner report: loads, the recommended system, the component breakdown, upgrade scenarios, a measured-versus-assumed table and the photos behind it. Customers who want the full engineering can open a portal view with every input and source. The report and design summary are written back to the WorkEdge job.
✓The same report works for homeowners, GCs and permit offices
AI proposes, you decide
Nothing the app reads from a photo goes into the calculation until a person accepts it. Manual entry always works with AI off.
Unknown is never zero
Anything you could not see shows up as a range with the assumption written out, not a hidden guess.
Same inputs, same answer
Deterministic, versioned code does the arithmetic, so a quoted load can always be reproduced.
