Conditions drive the plan, not the catalog
Troy's summer highs near 80°F aren't extreme on their own, but combined with genuine humidity they keep cooling systems working a full season, whether the ductwork dates to the 1960s ranch boom or the office-era construction that followed.
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
Troy's summers run warm enough -- average highs near 80°F -- that air conditioning load has to be sized for the newest office-era construction and the original 1960s-70s ranch stock alike, since equipment installed decades apart can share the same duct system after a partial retrofit.
