Rockville Air Duct Cleaning — City Code Paths, Not MoCo DHCA
King Farm, Twinbrook, and Town Center: municipal complaint doors plus County DEP humidity science
Inside Rockville city limits, rental maintenance complaints go through City code channels — Montgomery County DHCA does not take those interiors. County DEP still publishes mold and IAQ guidance for everyone. We clean ducts and dryer vents from Bethesda with flat rates and photos. Call (301) 809-4544.

Two governments, one set of trunks
Montgomery County DHCA Code Enforcement states it does not have jurisdiction inside Rockville (or Gaithersburg) for those municipal interiors. For leaks and maintenance inside the City, Rockville points residents to report a property maintenance code violation after written notice to the landlord. That split is the Rockville-specific civic angle.
County science still applies: DEP’s mold and indoor air quality pages push 30–50% humidity, venting dryers outdoors, and regular HVAC filter changes. City of Rockville has also aligned multifamily licensing updates with Maryland’s Tenant Mold Protection Act timelines (assessment after written notice, remediation windows) — read the City’s latest housing inspection news for the live dates.
King Farm townhomes, Twinbrook ranches, and Town Center condos all show up on our Bethesda route with Gaithersburg and Silver Spring. Local humidity reading: Rockville basement humidity and air ducts.

Rockville-only useful distinctions
Wrong agency wastes a week
Calling MoCo DHCA for a Rockville city rental interior is the wrong door. City code reporting after landlord notice is the civic path; we are the duct/vent path.
DEP still teaches humidity
30–50% RH and exhaust habits from County IAQ pages apply whether you are in the City or the unincorporated county.
Tenant mold timelines are state + city
Maryland’s Tenant Mold Protection Act sets assessment/remediation clocks after written notice — City multifamily rules are aligning. Duct cleaning does not pause those clocks.

Does Montgomery County DHCA handle my Rockville apartment mold complaint?
Generally no for interiors inside Rockville city limits — DHCA notes it lacks jurisdiction in Rockville. Use landlord notice, then City property maintenance reporting.
What humidity does County DEP recommend?
Montgomery DEP IAQ cites about 30–50% relative humidity and regular filter changes.
Do you enforce City housing code?
No. We clean ducts and dryer vents. Code and landlord-tenant processes stay with the City.
