Fast load calcs for permit deadlines

Most delays are missing information, not design time. Here is what to send the first time so your calculations come back fast.

The fastest projects we deliver are not the simplest ones. They are the ones where everything arrived in the first email. A Manual J on a 3,900-square-foot new build went back to one contractor within a day because the questionnaire was complete.

Send this with your first email

  • A dimensioned floor plan as a PDF
  • Elevations and a wall section, if available
  • Window sizes and types, or a window schedule
  • Insulation values for walls, ceiling and floor
  • The project address
  • The equipment type you plan to use, and any brand preference
  • What your building department asked for, or its comment letter if the permit was rejected

What slows things down

  • Plans without dimensions
  • Unknown window specs on a glass-heavy design
  • Changing equipment after Manual S is done
  • Finding out late that the jurisdiction also wants an energy report

When it is truly urgent

Call. We have turned around weekend requests for Monday permit appointments, and rush service is available. Tell us the deadline up front and we will tell you honestly whether we can make it.

Need a Manual J?

The Manual J is the number every other decision rests on. We calculate the heating and cooling load of every room from your plans, your orientation and your climate, so the equipment and ducts that follow are sized to the house, not to a rule of thumb.
