A Renter-Majority Area
The mall itself is a two-level enclosed shopping center in Sterling. The homes around it make up the Dulles Town Center census-designated place, and the housing looks nothing like the single-family neighborhoods nearby.

How Renters Should Ask for Duct Cleaning
Write Down What You See
Dust blowing from vents, visible mold, a musty smell when the system runs, or a dryer that won't dry. Take photos of registers and the filter.
Send a Written Request
Email or use the property portal so there's a date on record. Mention mold specifically if you see it — Virginia law requires landlords to address visible mold promptly.
Don't Hire on Your Own
Duct cleaning means opening the landlord's system. Get written approval, including who pays, before anyone works on it.
Keep Doing Your Part
Change filters on the schedule your lease sets and keep registers uncovered.
For musty smells in particular, the duct odor guide explains the common causes.
For Landlords and Property Managers
A rental unit changes occupants far more often than an owner-occupied home. Turnover is the natural time to inspect ducts and clean the dryer vent, before the next tenant's belongings arrive. Keep dated records of filter changes and vent cleanings; they answer most tenant complaints before they start. See dryer vent cleaning for what a full cleaning should include.
Renter and Condo Duct FAQs
Who is responsible for cleaning air vents in an apartment?
In Virginia, the landlord must keep the heating, ventilating and air-conditioning system supplied with the unit in good and safe working order, under Code of Virginia § 55.1-1220. Tenants usually handle simple upkeep the lease assigns, such as changing filters and wiping register covers. Duct cleaning, repairs and mold problems belong to the landlord.
Is HVAC the landlord's or the tenant's responsibility in Virginia?
The landlord's, for any heating and cooling equipment supplied with the rental. Virginia law also requires landlords to prevent moisture buildup and mold growth and to fix visible mold promptly. Leases can assign routine tasks like filter changes to the tenant, so read yours and report problems in writing.
Can a renter hire a duct cleaner without asking the landlord?
Ask first. Duct cleaning involves opening access panels and connecting equipment to the landlord's system, and most leases restrict alterations. Send a written request describing what you see, such as dust blowing from vents or a musty smell. If the landlord agrees, get approval in writing, including who pays.
Is Dulles Town Center in Dulles or Sterling?
The Dulles Town Center mall sits in Sterling, about five miles north of Washington Dulles International Airport. For census counts, the surrounding area is its own census-designated place, also named Dulles Town Center, separate from both Sterling and Dulles.
