Seattle Air Duct Cleaning Done Right: Our Diamond Package, Step by Step

R

No Compromises

Since 1969, we’ve been a trusted, consistent, and highly rated air duct and heat pump cleaning company. We don’t just clean, we REDEFINE service excellence, delivering unparalleled quality and a customer experience unlike anything you’ve ever had with any service company.

Our 5-Star Customer Experience Guarantee

 From your first call to the final walkthrough, we guarantee a 5-star experience. If anything falls short, tell us and we’ll make it right.

We have the highest quality TRUCK POWERED air duct cleaning equipment

Cleaning a complex air duct system isn’t a job for a carpet cleaning machine or shop vacuum. Our “Truck-Mounted”  Super Trucks create the negative airflow needed to remove even the worst contaminants and pull them into our truck where they belong.

We use a very powerful 12,000 CFM vacuum HyperVac system and 300 PSI of constant air pressure.

We are a NADCA member company, and every tech is trained to NADCA standards. 

NADCA is the global trade association for the air duct cleaning industry. They support member’s success with standards, education, certification, and advocacy to promote the highest quality and ethical services. It’s VERY important to only use a NADCA member company for air duct cleaning.

Electronic Indoor Air Quality Test Emailed To You

We test your air for the following and discuss/email you a report:

Volatile Organic Compounds (VOCs)
Detects the presence of Volatile Organic Compounds (chemical pollution) commonly given off by interior building materials such as carpet, paint, upholstery, vinyl flooring, cleaning products, cosmetics, burning wood, etc.

Carbon Dioxide (CO2)
It uses an NDIR (Non-Dispersive Infrared) sensor to detect carbon dioxide (non-combustible gas) formed during respiration, organic decomposition, or combustion. CO2 may threaten humans if breathed in high enough concentrations.

Particulate Matter (PM2.5 & PM10)
Measures the amount of inhalable particulate matter that can penetrate the lungs and cause health problems. Examples include dust, pet dander, pollen, and other airborne substances less than 2.5 and 10 microns in size.

Temperature, Humidity, Dew Point and Pressure
Measures indoor air Temperature, Dew Point Temperature, Relative Humidity, and Building Pressure, any one or all
of which may adversely affect building occupants or the building itself.

We set up a HEPA AIR CLEANER filtration system to control dust while we work

This system continually cycles your home’s air over 10 times to filter out any remaining dust particles during the cleaning process.

We protect your home

A complete and in-depth cleaning requires us to go into every room that contains an air duct or cold-air return. At Alpine, the work will not begin until the floors, doorways and outside wall corners are protected. Slip-on shoe covers, floor tarps and plastic corner guards create a barrier between our equipment and your home.

Air Duct Cleaning Protection
R

We open an access port to connect our hose

To connect our 10″ vacuum hose, your technician cuts a small access port into your main trunk line or plenum, the large duct right at your furnace or air handler. It is a normal part of a whole-system duct cleaning.

When the cleaning is done, we close the opening with a sheet-metal access plate, screw it in place, and seal every edge with foil tape made for ductwork, so the opening is fully closed. The plate can be removed for future access and sealed back in place.

Prefer a permanent door that opens and closes for future access? We can install a metal access door instead, at additional cost. See our add-on services below.

Super vacuum attached to the main trunk line

We connect a 10″ vacuum hose to your main trunk line and create the massive negative air flow needed to remove the dirt, dust and contaminants that are hiding in the system.

R

Compressed air tools into each individual vent for superior agitation

Pulling large volumes of air toward the truck, we now feed our soft rubber, high-pressure air scrubbing tools down each of the vent lines, forcing all the contaminants into the trunk line where it’s extracted into the super truck. This removes dirt, dust, pollen, and pet dander that has been collected over the years.

Cold air return cleaning

After all the duct work on the supply side is completed, we move to the cold-air return system. The main return grill is removed (unless attached to a wall or painted surfaces) and the venting is cleaned, followed by the vent covers and lines throughout the home.
R

Trunk/Plenum/Air Handler

This step is completed with the removal of the furnace panels and cleaning of the exterior surface of the blower, electric motor, and cabinet. We use a vacuum and compressed air. We clean only; we do not inspect, test or service burners, heat exchangers or gas parts (call a licensed HVAC contractor for that). The trunk lines and plenums are also cleaned.

We will also deep clean electrostatic filter systems if equipped or clean existing filters/replace them with customer supplied.

We email you BEFORE & AFTER cleaning photos of the inside of your ducts

Alpine BioGuard™ Sanitizing & Disinfecting Treatment

This ADDS our EPA-registered BioGuard™ sanitizing & disinfecting treatment to each register, grill & vent boot to help kill bacteria, viruses & remove allergens! And as a final step, we fog our cleaning treatment through the system, which leaves a light fresh scent.

BioGuard™ uses Bioesque, an EPA-registered disinfectant (EPA Reg. No. 87742-1-92595), on your registers, grills & vent boots. Wood grills are porous, so we skip those and let you know. We use professional, EPA-registered products applied per manufacturer directions. Safety Data Sheets for all our products are on our SDS page.

Alpine CoilRenew™ Outdoor HeatPump/AC Unit Cleaning Process

Before-and-after air duct cleaning results

Your outdoor AC or heat pump collects dust, pollen, leaves, and nesting debris all year. Once that packs into the coil fins it restricts airflow — the system runs longer cycles, uses more electricity, and puts extra strain on the compressor, one of the most expensive parts of your system.

Our process includes:

  • Power shut off at the exterior breaker before the unit is opened
  • Top grille and protective panels removed to reach the interior, where most debris collects
  • Leaves, nesting material, and pollen mats hand-removed and vacuum-extracted
  • A coil-safe foaming treatment worked between the aluminum fins to lift embedded buildup
  • Controlled low-pressure rinse, then reassembly and a full operation check

Most systems benefit from this once a year — more often with heavy pollen or nearby vegetation. This is not a surface rinse: if buildup is visible from the outside, there is usually more of it hidden inside.

Metal Duct Access Door Upgrade ($110 installed)

Permanent metal duct access door with frame and latches

Our standard close is a removable sheet-metal plate, screwed in place and sealed with foil tape made for ductwork. Prefer a permanent door that opens and closes? For $110 installed, we put a metal access door in that opening instead.

The upgrade includes:

  • A metal access door with its own frame and latches
  • Installed at the port we already open, so there is no extra cutting
  • Screwed to the duct and sealed around the frame
  • Opens and closes with its latches, with no screws or tape to redo

Ask your technician on the day of service, or let our office know when you book.

Ours is. We set up a HEPA air cleaner to control dust while we work, and we protect your floors, doorways and wall corners before we start.

Common Questions

How much does air duct cleaning cost in Seattle?

Our Essential Basic Package starts at $474.95 for homes up to 1,500 sq ft, with $75 off already applied through December 31, 2026, plus Washington sales tax. Area minimums apply for outlying cities. Larger homes are priced by square footage, and we confirm your exact price before any work starts.

What does the Diamond Package add?

We highly recommend our Diamond Package! For +$249.95 it ADDS our EPA-registered BioGuard™ sanitizing & disinfecting treatment to each register, grill & vent boot to help kill bacteria & viruses and remove allergens! As a final step, we fog our cleaning treatment through the system, which leaves a light fresh scent. Diamond also includes an Indoor Air Quality test with emailed results and our 2-Year Diamond Loyalty Program.

How do you clean air ducts?

We protect your floors, doorways & wall corners and set up a HEPA air cleaner to control dust. Then we connect a 10″ vacuum hose from our truck right to your main trunk line and feed soft rubber, high-pressure air scrubbing tools down each vent line, pushing the dust to the trunk line where the truck pulls it out. We clean the cold-air returns too, and email you before & after photos of the inside of your ducts.

How long does air duct cleaning take?

A typical single-system home takes 2 to 4 hours. Bigger homes or homes with two systems take longer.

Do you have to cut an access port?

Yes. To connect our 10″ vacuum hose, your tech cuts a small access port into your main trunk line. When we finish, we close it with a removable sheet-metal plate, screwed in place and sealed with foil tape made for ductwork. Want a metal door that opens & closes instead? We install one for $110.

Do you sanitize the ducts?

We clean the duct runs mechanically with our truck system. No product is EPA-registered to sanitize the inside of ductwork, so we won't claim that. What we do on Diamond is sanitize and disinfect every register and vent boot where most grime builds up. Safety Data Sheets for everything we use are on our SDS page.

Are you a NADCA member?

Yes. We are a NADCA member company, and every tech is trained to NADCA standards. The NADCA badge on this page is live, so you can click it to confirm our membership on NADCA's own website.

Do you clean air ducts on weekends?

Yes! We clean air ducts 7 days a week, Monday through Sunday. The first appointment of the day arrives between 8:00 and 8:30 am, and you get a text when your tech is on the way.

How often should air ducts be cleaned?

We recommend cleaning every 2 to 3 years. Sooner if you have had construction work, smoke or pet issues, or if anyone in the home has bad allergies.

Can you clean my dryer vent on the same visit?

Yes. Dryer vent cleaning is $99.95 when you add it to your air duct cleaning, since we are already there.
