Start from what's actually wrong
So much of Sterling Heights went up in one single-generation building wave that a cooling-repair visit is often diagnosing the same ranch-era ductwork and electrical panel that a neighbor three streets over is also dealing with.
A written scope should spell out
- The existing condition and probable cause
- Prep and protection for the rest of the house
- Material and equipment compatibility
- Permit filing, testing, cleanup, and restoration

Sterling Heights context
Much of Sterling Heights was built during the 1950s-70s postwar boom that followed Chrysler and Ford's expansion into the township, so a large share of the city's cooling equipment and ductwork shares that same construction era. Summer highs in the low 80s combined with real humidity keep air-conditioning systems working through a genuine cooling season here.
