Pause when a cheap offer turns into a fear pitch
Review coupon definitions, then connect the observation to its source, system location, and a written scope.
DIRECT ANSWER
Start with the condition, not the sales package
A low advertised price can become expensive when the offer covers only a few vents or excludes returns, equipment, access, and collection. The problem is not a discount by itself. The warning is a vague scope followed by urgent add-ons, health fear, unshown contamination, or a demand for immediate payment.
EPA advises consumers to get written estimates, reject sweeping health claims, and ask providers to show contamination that justifies cleaning. Keep the system closed and safe while you review any new finding. You do not have to approve an add-on at the doorway.

What deserves a closer look
Fear without evidence
Statements about toxic mold, endangered children, or imminent equipment failure require evidence and appropriate expertise. A sales photo without location context is not enough.
Uncontrolled add-ons
Sanitizers, sealants, UV devices, filters, repairs, and replacements need their own reason, terms, and approval.
