How much does air duct cleaning cost?

Our pricing is customized to your home based on size and duct condition. We give you a FREE inspection first — no obligation, no pressure. You'll know the exact flat-rate cost before we start. Beware of $99 'blow-and-go' scams that upcharge you later.

How long does the process take?

A proper, professional-grade cleaning takes 3 to 5 hours for an average-sized home. We use a negative pressure system that requires careful setup to ensure zero dust escapes into your living space.

Will this make a mess in my house?

Absolutely not. Our negative pressure system pulls all debris directly into our specialized truck-mounted or portable HEPA vacuums. We wear shoe covers, use drop cloths, and leave your home cleaner than we found it.

How often should I have my ducts cleaned?

The EPA recommends every 3 to 5 years. However, if you have pets, recent renovations, allergies, or asthma, you may benefit from cleaning every 2 years.

Do you offer emergency or same-day service?

Yes. We have technicians on standby 24/7 for the DMV area. If you suspect a mold issue, have a severe allergy attack, or notice a burning smell from your vents, call us immediately.

Is a gas furnace or heat pump better for DMV winters?

Modern heat pumps (especially cold-climate models from Mitsubishi, Daikin, and Carrier) work efficiently down to 5°F, which covers 95%+ of DMV winter days. Traditional gas furnaces provide stronger heat output during the rare single-digit cold snaps. Dual-fuel systems — a heat pump with a gas furnace backup — give you the best of both worlds: heat pump efficiency above 35°F and gas heat below that threshold. For most DMV homeowners, a heat pump or dual-fuel system is the most cost-effective choice in 2026.

Which costs more to operate in the DMV?

At current 2026 DMV energy prices (Pepco electricity ~$0.14/kWh, Washington Gas ~$1.20/therm), a heat pump is typically 30-50% cheaper to operate than a gas furnace for heating, thanks to the heat pump's 300%+ efficiency (COP of 3+). The cost advantage narrows during extreme cold when heat pumps lose efficiency. For cooling, both systems use the same air conditioner compressor, so summer costs are identical. Annual operating savings of $400-$800 for heat pumps over gas are common in the DMV.

Do gas and electric systems use different ductwork?

The ductwork itself is similar, but sizing requirements differ. Heat pumps move larger volumes of air at lower temperatures than gas furnaces, so they need slightly larger duct sizes and properly sized returns. If your home was designed for a gas furnace and you switch to a heat pump, an HVAC contractor should verify duct sizing. Undersized ducts with a heat pump cause "cold blow" — air from the vents feels cool even though the system is heating.

What rebates are available for switching to a heat pump?

The DMV has some of the best heat pump incentive stacking in the country. Federal 25C tax credit: 30% of costs up to $2,000. Maryland EmPOWER rebates: $500-$2,000 depending on utility (BGE, Pepco). Virginia Dominion rebates: $250-$500. DC DCSEU rebates: up to $2,500 for qualifying heat pump installations. IRA HEEHRA rebates for low/moderate income: up to $8,000. Total stacking can reach $5,000-$12,000 for qualifying households.

Should I clean my ducts when switching systems?

Absolutely. Switching HVAC systems is the ideal time for duct cleaning because: the old system is disconnected (full access to the plenum), the new system starts with clean ducts for maximum efficiency, and the contractor can verify duct sizing and sealing during the process. We coordinate with HVAC installers throughout the DMV to schedule cleaning during the changeover day.

Ductwork Considerations When Switching

Switching from gas to electric or vice versa affects your ductwork. Heat pumps deliver air at 90-100°F (gas furnaces deliver at 120-140°F), so they need to move more air to deliver the same BTUs. If your existing ductwork was sized for a gas furnace, it may be undersized for a heat pump. This causes "cold blow" — air from the vents feels lukewarm even though the system is heating — and it strains the blower motor.

Before any system switch, we recommend a full duct assessment: sizing verification, leak testing, and cleaning. Homes in older DMV neighborhoods like Bethesda, Falls Church, and Takoma Park often have original ductwork from the 1950s-1970s that is undersized even for their current gas furnace. A system upgrade is the perfect time to right-size your ductwork.

Our Pre-Switch Duct Assessment Includes:

Duct sizing verification for new system type

Duct leakage test (duct blaster)

Airflow measurement at each register

Return air adequacy check

Interior cleaning of all ductwork

Joint sealing and insulation assessment

Our Recommendation for DMV Homeowners

For most DMV homes in 2026, a dual-fuel system (heat pump + gas backup) or a cold-climate heat pump offers the best combination of comfort, efficiency, and cost savings — especially with current rebates. Clean, properly sized ductwork is essential regardless of which system you choose.
