Conditions drive the plan, not the catalog
Winter lows near 18°F and relative humidity around 85 percent mean a heat pump proposal for a Troy home needs a real answer for cold-weather output, not just a mild-climate default.
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
Michigan's wide seasonal swing -- winter lows near 18°F to summer highs near 80°F -- means a heat pump sized for Troy has to perform across a bigger temperature range than milder climates require, whether it's serving a 1960s ranch or newer office-era construction.
