Have these ready when you reach out and we'll turn your report around fast.
-
Project location
The full address, or at minimum the county the project is in.
-
A basic scaled plan
A scaled print showing the windows and measurements. We can work from hand drawings, but non-professional plans add $0.01/sq ft since they take more time.
-
Front-door orientation
Which direction the front door faces (south, northeast, etc.).
-
Insulation R-values
R-values for floors, walls, and ceilings — only if they differ from standard.
-
Window values
Window U-values, or the approximate age of the windows and the number of panes — only if they aren't standard.
-
Equipment models
Models of the installed or preferred units (condenser, coil, and furnace/air handler). We can size to the outcome of the Manual J with a basic model number.
