Local considerations
What Cornwall conditions change about the plan
- Humid summers along the river
- The St. Lawrence corridor produces humid summers, so cooling design here leans on moisture removal. Correct sizing matters more than extra capacity: an oversized system cools quickly and leaves the air damp.
- Post-war and mid-century housing
- Much of Cornwall's housing stock dates from the post-war and mid-century period, with ducts originally designed for older, less demanding equipment. Duct and return capacity is worth measuring before higher airflow equipment is selected.
- What we still need before this page can carry local evidence
- Completed Cornwall project details, photos, and permission to publish them are outstanding.
