Conditions drive the plan, not the catalog
A system replacement in Troy typically means reconciling one of two construction eras — 1960s-70s ranch subdivisions or the office corridor that followed 1969 — each with its own starting point for duct condition and electrical capacity.
Make sure the scope addresses
- Current condition and the likely cause
- How the work area and rest of the home get protected
- Compatibility between new materials and existing equipment
- Permits, testing, cleanup, and finish restoration
- Exclusions, warranty coverage, and change-order handling
Troy context
A system replacement in Troy usually falls into one of two eras: the 1960s-70s ranch subdivisions built after the city's 1955 incorporation, or the office and retail construction that followed the Somerset Mall's 1969 opening on Big Beaver Road. Each era comes with its own starting point for duct condition and equipment sizing.
