Start with diagnosis and load
Plan cooling around heat gain, humidity, airflow, electrical capacity, condensate, and realistic equipment placement. A useful evaluation connects the symptom to controls, distribution, envelope, ventilation, drainage, electrical or fuel supply, and equipment operation.
Questions for the scope
- What measurements support the diagnosis or equipment selection?
- What distribution, electrical, venting, piping, or condensate work is included?
- How will access and finishes be protected?
- What permits and startup checks apply?
- What maintenance and warranties follow?
Lowell building context
Lowell pairs mill-era brick buildings and dense worker housing with triple-deckers, later suburban streets, and adaptive-reuse lofts. HVAC planning must reconcile masonry, tall stacks, compact chases, old hydronics, electrical limits, heat-pump performance, humidity, and noise.
