Which heating or cooling components need attention?
Dust or construction residue around a furnace or air conditioner does not automatically mean every component needs the same work. Ask which parts are included, such as the blower assembly, evaporator coil, or accessible heat-exchanger face, and whether the equipment design permits the proposed access. Photograph model labels and visible buildup before requesting an estimate. A clear component-by-component scope helps distinguish cleaning from diagnosis or repair, which may require a separate qualified assessment.
