Is airflow weak at several registers?
Weak airflow or visible buildup around accessible equipment may warrant an inspection of the blower assembly, evaporator coil, and condensate path. These are distinct components, and cleaning one does not establish that the others need the same work. Ask what must be removed for access, how the coil will be cleaned in place if that is proposed, and how condensate drainage will be checked. Photograph equipment labels and visible conditions beforehand; system design and access at your Chatham property shape the scope.
