Routine duct cleaning is not automatically necessary.
EPA guidance says duct cleaning should generally be considered when there is substantial visible mold growth inside hard-surface ducts or HVAC components, vermin infestation, or excessive dust/debris that is actually being released into the home.
What EPA actually says
The EPA does not recommend routine duct cleaning simply on a fixed calendar. The reason matters: visible contamination, pests and actual debris problems are different from normal household dust.
Renovation dust is a different clue
Recent construction or remodeling can create an inspection reason if substantial debris entered the system. That is different from assuming every older home needs a full cleaning.
Be careful with mold claims
Suspected mold in HVAC components can require a different professional pathway than ordinary duct cleaning, especially where Texas mold rules apply. Moisture source control matters more than simply treating a symptom.
What a useful duct quote should explain
- What evidence shows cleaning is warranted?
- Which system components are included?
- Is pricing per system, per vent or a fixed scope?
- Are sanitizers/biocides optional, and why are they being proposed?
Check this against your own home.
