Housing and equipment in West Chestermere
A converted cottage rarely has the mechanical layout of a purpose-built house.
- Heating may have been added after the fact, ducting threaded through a crawl space or a low basement, and successive additions served by extending runs that were never sized for the finished floor area.
- Rebuilt homes on the same street are the opposite: purpose-designed mechanical rooms, sealed high-efficiency equipment, and sometimes more than one system.
- Two neighbouring addresses can need entirely different assessments.
