Conditions drive the plan, not the catalog
Furnaces original to Troy's 1960s-70s subdivision boom are working through winters that regularly drop near 18°F, and that combination of age and cold puts a lot of this equipment past a reasonable service life.
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
Winters in Troy average lows near 18°F in January and February, with relative humidity running near 85 percent -- a combination that puts real strain on heating equipment installed during the city's original 1960s-70s subdivision boom and hasn't been replaced since.
