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 Unrivaled Guarantee
Always yes—Quality and experience you can trust, no questions asked. We always 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-certified company and have NADCA-trained technicians.
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 only to use a NADCA-certified 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 for a dust free experience
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.
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.
Compressed air tools into each individual vent for superior agitation
Cold air return cleaning
Trunk/Plenum/Air Handler
This step is completed with the removal of the furnace panels and cleaning of the exterior surface of the blower, gas combustion chamber, electric motor, and cabinet. We use a vacuum and compressed air. The furnace is inspected to make sure everything is running efficiently. 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
SEE the difference with our cleaning process! We have the proper equipment to get the job done right since 1969!
We clean your existing furnace filters OR replace with CUSTOMER SUPPLIED filters at no extra charge

Respicare Whole Home Air Purification Systems
Alpine CoilRenew™ Outdoor HeatPump/AC Unit Cleaning Process
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.

A live feed of new reviews as customers post them.
The company was great to work with - they were quick to follow up answering questions, arrived on time, and were very detailed to provide information on what needs to be done to clean HVAC ducts and dryer vents. Their technician Jesus was right on time, very knowledgeable about how to get the job done, and completed it ahead of schedule. Everything was clean and put back together correctly, he provided additional information on how to keep the system and house clean. Pictures before and after were provided, a huge difference in the entire system.
Sebastian performed the duct cleaning, sanitizing, air quality testing and some other services. Very personable and efficient. Cleaned up like he wasn’t here.
We had our HVAC duct and vent cleaning with Alpine Specialty Services. Great service from our first phone call through the whole cleaning. Thank you to our very professional technicians, Steve and Sebastian. We had a walk-through before and the results were shared right after the service, complete with before and after pictures. We highly recommend!
Great service from start to finish. They cleaned the HVAC ductwork in a system that had not been cleaned in over twenty years. They took before and after photos and the results were amazing.
Polite, experienced salesperson and service provider. We felt confident that Anthony had been thorough and done an excellent job cleaning our air ducts and HVAC. Recommend!

Common Questions
How much does air duct cleaning cost in Seattle?
Pricing depends on number of vents and the size of the system. Most single-system homes land in the $400 to $700 range. We ask a couple of questions on the phone so we can give you an honest quote up front.
Are you NADCA-certified?
Yes. We follow NADCA cleaning standards and our AirLux method covers the full system, not just the vent covers.
How long does air duct cleaning take?
A typical single-system home runs 2 to 4 hours. Bigger homes or homes with two systems take longer.
How often should ducts be cleaned?
Most experts say every 3 to 5 years for an average home. Sooner if you have had construction work, smoke or pet issues, or if anyone in the home has bad allergies.
Do you clean the dryer vent at the same time?
We can. A lot of customers bundle dryer vent cleaning with air duct cleaning since we are already on site.
