❌ Failed Permit Submissions
You paid for Manual J calculations. They come back rejected — wrong values for Rhode Island's climate, doesn't meet the Rhode Island Energy Code (2021 IECC). Now you're delayed and your client is frustrated.
✓ ProCalcs gets it right: Rhode Island-specific climate data, Rhode Island Energy Code (2021 IECC) compliant. First-time approval.
"Why Do You Ask So Many Questions About My Project?"
Because Rhode Island's climate has unique characteristics — and generic HVAC calculations miss them entirely.
Rhode Island is the smallest state in the US but packs significant climate diversity. Providence has genuine cold winters with design temps around -4°F, while Newport and the southern coastal communities are moderated by the Atlantic Ocean. Rhode Island has 5 counties but permitting is handled at the municipal level across 39 cities and towns. High energy costs make proper sizing especially important for Rhode Island homeowners.
- Actual window U-factors and SHGC values (not generic assumptions)
- Real insulation type and R-values (Zone 5A (Cool-Humid) statewide — Providence, Cranston, Woonsocket, Pawtucket, East Providence, Newport, and all Rhode Island communities. Long Island Sound and Narragansett Bay coastal moderation reduces extreme temperature events. code minimums apply)
- The products you're actually installing (not what "usually" gets installed)
- Rhode Island-specific construction details (local climate conditions, elevation, regional building practices)
Yes, it takes 5 extra minutes. But it saves you days of permit delays and expensive resubmittal fees.
We don't guess. We ask. We verify. We get your Rhode Island HVAC calculations right.
