Duct cleaning is one of the most oversold services in the HVAC industry. Aggressive marketers pitch “$99 whole-house duct cleaning” specials that turn into $800–$1,500 upsells once the technicians arrive, and blanket-clean every duct in the house whether the ducts actually need attention or not. PolarCore’s approach is different: honest scope evaluation using static pressure measurement and visual inspection first, targeted cleaning of the sections that actually need attention, and transparent pricing that isn’t padded with unnecessary “sanitizer” charges or upsells. Ducts in a well-maintained house with correct MERV-rated filtration don’t accumulate significant dust or biological growth. Ducts do benefit from cleaning under specific conditions: post-renovation cleanup, remediation after prior improper HVAC work, biological growth from humidity issues (which requires addressing the humidity source, not just cleaning), or pest infestation in vacant properties.
Major renovation or new construction produces substantial dust, sawdust, and drywall particulate that accumulates in the HVAC system. Duct cleaning after renovation removes this construction debris and prevents ongoing recirculation. Recommended when: renovation involved drywall work, flooring installation, framing modifications, or extensive interior work. Typical scope: full supply and return duct cleaning, air handler cleaning, evaporator coil cleaning, and filter replacement.
Prior HVAC service by inexperienced contractors sometimes leaves contamination: fiberglass debris from cut duct insulation, adhesive residue from improper repairs, or biological growth from moisture-related installation defects. Duct cleaning addresses this legacy contamination as part of correcting the underlying installation issue.
Mold, mildew, or biofilm growth in ducts or on the evaporator coil typically indicates chronic humidity issues that must be addressed for cleaning to have lasting effect. Diagnostic includes humidity measurement, evaporator coil inspection, and duct interior inspection. Remediation combines: cleaning of affected sections, evaporator coil cleaning and UV-C lamp installation, and humidity control equipment (whole-home dehumidification or ventilation modifications). Cleaning alone without addressing the humidity source produces regrowth within months.
Vacant properties with rodent or insect infestation can have accumulated contamination in ducts that requires cleaning as part of remediation. Typically part of a broader pest control and property preparation process.
