When you come back to a report, the app may ask you to rate it on the App Store. After that it won't ask again for 120 days. Calculations and your saved jobs are unchanged.

Tapping the App Store event "Equipment Check by Manual S" opens the equipment check in the app. The App Store listing also has a new name and a Spanish (Mexico) description. Your calculations and saved jobs are unchanged.

See where the load comes from: walls, ceiling, floor, windows, sun, infiltration, people, and ducts. The PDF has a second page with the design conditions, where they came from, the load by component, and every input. Equipment check: compare a unit's cooling capacity, heat pump capacities, or furnace output with the load and the ACCA Manual S range. See the heat pump balance point and the backup heat it needs. Fuel use check: compare the load with last year's gas, oil, or propane use. New inputs: indoor design temperatures, shaded glass, window U-factor and SHGC from the label, a blower door CFM50, and ducts in the attic, crawlspace, basement, or garage. Can't see the insulation? Fill it in from the year the house was built. Saved jobs, company details, and your logo now sync through iCloud, and your logo appears on the report. On iPad, picking a weather station by town takes one tap again.

Pick up where you left off. The app now saves a draft of your calculation and restores it when you reopen the app, including changes you haven't saved to a job yet. Add a client's name, property address, notes, and your company contacts to the PDF. Long notes continue onto additional pages. You can save your company details once and reuse them on new jobs. Drafts and saved jobs stay on this device. Your saved calculation changes only when you choose Save changes.

Use "New job" to start a separate calculation for each customer. "Save changes" updates the current job, while "Save a copy" keeps a separate version. The app asks before you leave unsaved changes. Find weather stations by city, state code, or full state name. If there are no matches, you can search by ZIP code. The Report button is easier to find. The app checks each PDF before opening the share sheet and shows an error if it can't create the report.

Design temperatures now cover the whole country. Enter the site ZIP code and the app picks the nearest weather station, anywhere in the US. You can see which one it chose and change it, search by town instead, or enter your own design temperatures. The subscription screen now lists what the subscription includes: saved jobs and the one-page PDF report, as well as the load. You can see what you are getting before the trial starts.

Saved jobs. Name a calculation and it is waiting on your next visit, with every input exactly as you left it. The list shows the heating load, cooling load and tonnage for each job, so you can find the right one without opening it. One-page PDF report. See the page before you send it — design loads, equipment size, and every input the numbers came from — then share it from anywhere iOS can share a file. It is named after the job. Built for iPad. On a 13-inch screen the form and the report sit side by side, and the page updates as you change the envelope. All orientations, and correct in a resized window. Fixes: reopening a saved job now keeps the humidity band and the hand-entered U-factor it was saved with, instead of resetting them to the defaults for that city.

Enter your own U-values. Walls, ceiling and floor now take a custom assembly U-factor alongside the presets — for the build that isn't on the list. Pick "Custom…" in any insulation row and type it in. A value outside the usual range for that assembly is flagged, so an R-value typed into a U-factor field can't quietly turn into a tonnage.
