Is airflow uneven from room to room?
Furnace and AC cleaning may involve the blower assembly, evaporator coil, drain path, and nearby compartments, but the appropriate scope depends on equipment design and access. For a Burlington home, photograph the furnace or air-handler model label, note unusual noise or weak airflow, and identify which registers are affected. Ask whether the blower will be removed, whether coil washing is performed in place, and how controls and sensors are protected. This makes the proposed work easier to compare with the equipment condition.
