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.

How often should I change my air filter in the DMV?

In the DMV area, change 1-inch filters every 30-60 days during peak seasons (summer and winter when your system runs constantly). During mild spring and fall months, every 60-90 days is typically fine. If you have pets, change every 30 days year-round. 4-inch and 5-inch media filters last 6-12 months. Check your filter monthly regardless — our region's pollen counts and humidity accelerate filter loading faster than drier climates.

What MERV rating should I use for my home?

MERV 11-13 is the sweet spot for most DMV homes. MERV 11 catches dust mites, pollen, mold spores, and pet dander effectively. MERV 13 also captures some bacteria and smoke particles — ideal during wildfire smoke events that increasingly affect our area. Going above MERV 13 in a standard residential system can restrict airflow unless your HVAC was specifically designed for it. Always check your owner's manual or ask your HVAC tech before upgrading.

Can a higher MERV filter damage my HVAC system?

Yes, if your system was not designed for it. Higher MERV filters have denser media that restricts airflow. A MERV 16 filter in a system designed for MERV 8 can reduce airflow by 30-40%, causing the evaporator coil to freeze, the blower motor to overheat, or the compressor to short-cycle. Most residential systems handle MERV 11-13 without issues. If you want MERV 14+ filtration, consider a separate bypass HEPA filter system instead of upgrading your return filter.

Are expensive filters worth the cost?

It depends on your situation. For a healthy household with no pets in a newer home, a quality MERV 8-11 filter ($8-$15) changed regularly works fine. For allergy sufferers, pet owners, or homes near construction, a MERV 13 pleated filter ($15-$25) provides measurably better particle capture. Avoid cheap fiberglass filters ($1-$3) — they catch less than 20% of particles and offer almost no protection for your HVAC system or your lungs.

What size filter does my HVAC system need?

Check the existing filter or the filter slot dimensions. Common DMV residential sizes include 16x25x1, 20x25x1, 16x20x1, and 20x20x1 for 1-inch filters. Some systems use 4-inch or 5-inch media filters (like 16x25x4 or 20x25x5). The exact size is usually printed on the side of your current filter. If the filter slot has no markings, measure the inside dimensions of the slot — you want a filter that fits snugly without gaps around the edges.

Does air duct cleaning reduce how often I need to change filters?

Yes. After a thorough duct cleaning, your filters accumulate debris more slowly because the ducts are no longer shedding dust into the airstream. Most of our DMV customers report their filters stay cleaner 20-30% longer after professional cleaning. However, this does not mean you should skip filter changes — it means your air quality stays better for longer between changes.

DMV Homeowner Guide

Air Filter Replacement Guide

The DMV area's unique mix of humidity, pollen, and seasonal allergens means your air filter works harder than in most US cities. The wrong filter — or a dirty one — costs you money, damages your HVAC, and worsens indoor air quality. This guide covers everything DMV homeowners need to know.

MERV Ratings Explained (In Plain English)

MERV stands for Minimum Efficiency Reporting Value. It measures how effectively a filter captures particles of different sizes. The scale runs from MERV 1 (barely filters anything) to MERV 20 (hospital operating room level). For residential HVAC in the DMV, you are choosing between MERV 8 and MERV 13 — and that choice matters more here than in less humid regions because our climate produces more mold spores, pollen, and moisture-related particulates than most of the country.

DMV Seasonal Filter Calendar

The DMV area's diverse allergen profile means your filter needs change with the seasons.

Spring (Mar-May)

Key Allergens:Tree pollen (oak, maple, cherry), grass pollen

Recommendation:MERV 13, change every 30 days

Summer (Jun-Aug)

Key Allergens:Mold spores (high humidity), ozone, wildfire smoke

Recommendation:MERV 13, change every 30-45 days

Fall (Sep-Nov)

Key Allergens:Ragweed, leaf mold, dust mites

Recommendation:MERV 11-13, change every 45-60 days

Winter (Dec-Feb)

5 Filter Mistakes DMV Homeowners Make

Using the cheapest fiberglass filter

Fiberglass filters catch less than 20% of particles. Spend $10-$15 on a MERV 11 pleated filter — the difference in air quality is dramatic.

Installing the filter backwards

Look for the arrow on the filter frame — it points in the direction of airflow (toward the blower). Installing backwards blocks airflow and can damage the filter media.

Jumping to MERV 16 for allergies

A MERV 16 filter in a standard residential system restricts airflow severely. Use MERV 13 in your return, and add a standalone HEPA purifier in bedrooms for extra filtration.

Forgetting about return vent filters

Some DMV homes have filters in individual room returns as well as the main return. Check all filter locations. A clogged secondary filter can create negative pressure in that room.

Not changing filters during mild weather

Even when your HVAC runs less in spring and fall, the fan still circulates air. Filters still collect dust, pollen, and mold spores. Check monthly regardless of HVAC runtime.

Why Filters Alone Are Not Enough

Your air filter catches particles before they enter the HVAC system, but it cannot clean what is already inside the ductwork. After years of accumulation, dust, mold, and debris build up on duct walls downstream of the filter. Every time the blower runs, some of that accumulated contamination breaks loose and enters your living spaces — completely bypassing the filter. Professional duct cleaning removes this internal reservoir, and a good filter prevents it from building up again as quickly. The two services are complementary, not interchangeable.
