How Is It Done?

Our Process

First we’ll walk the home with you to identify the location of your heat registers and furnace. Throughout our visit, we’ll explain our process and the value we’re adding. We finish each air duct cleaning with our detailed 3 Step Quality Control process.

Cleaning Process

  1. First we will remove all large debris from each heat register boot with a portable shop vac.
  2. We will then seal each register with plastic or magnetic material (depending on the surface we are covering).
  3. Each register is placed under negative pressure by attaching our industry leading Hypervac Negative Air Machine (big vacuum) at the location of your furnace.
  4. Once your system is under negative pressure, we will run two powerful compressed air cleaning tools (“agitation” and “air sweep”) down the full length of each register.
  5. The last air ducts to be cleaned are the main trunk lines that lead back to the furnace.
  6. Finally, we agitate and remove dust and debris from your furnace including the blower motor, air handler and interior cage.

Three-Step Quality Control

  1. To ensure quality, we inspect accessible internal surfaces of the duct work to ensure cleaning is thorough and complete.
  2. We then run the HVAC system to ensure that the system is fully operational.
  3. After all work is done, we complete a final walk through with vacuum and duster to ensure all work areas are as clean as or cleaner than their state prior to the air duct cleaning service.

Frequently Asked Questions

Is it ok to be home during the air duct cleaning?

Absolutely. You are more than welcome to stay during the cleaning, we like to show off our equipment and air duct cleaning process. The process can be pretty noisy as we work from room to room as well as a constant noise from the furnace area and at our van.

Is it ok to have my pets at home during the air duct cleaning?

Absolutely. Friendly dogs and cats are usually fine, although if they are escape artists we will work with you to keep them safe from escape. During the air duct cleaning we run a compressed air line in through the front door. The door will be propped open about 1” with a door stop, but this might not be sufficient depending on your animals.

What furnace filter to you recommend?

We don’t currently sell air filters with our air duct cleaning. We strongly recommend that you use a MERV 11 or MERV 13 air filter with as many pleats as possible. Use the largest size filter possible, if your furnace or filter cabinet has room for a 4” filter, we strongly recommend using a 4” filter.

I noticed that your air duct cleaning includes a “furnace cleaning” is this the same as a furnace service?

Our furnace service goes above and beyond the furnace cleaning that is included in the air duct cleaning. These services should be scheduled separately when needed. If both services are needed we recommend having the air ducts and furnaced cleaned prior to having it serviced.

Do you offer air duct repair services?

No. Unfortunately we don’t currently offer air duct repair services, but if they need to be cleaned we are happy to help!

Do you clean flexible ductwork?

Yes! Using our compressed air tools are able to clean flexible ductwork without causing tears or abrasion.

Is Better Air NW NADCA Certified?

While we aren’t NADCA certified, we do follow all of their suggestions and guidelines!

How often should I get my air ducts cleaned?

It is recommended every 3-5 years. If you’ve had remodeling done, live in a dusty environment, or have pets, you may need it done more frequently.

Recent Testimonials

We use this company for vent cleaning and HVAC maintenance. Couldn't recommend them more!

They are super helpful and responsive. Very respectful of your home, take their time and are thorough.

Suggest getting a quote at min! Their online tools and payment options are easy to use. I also find their prices fair. You can get a discount if you bundle, so why not!

Steve T. | Seattle, WA | 2022

We just moved into our home a year ago and have been meaning to swap our our oil furnace and upgrade our water heater. We called BetterAirNW for a quote and the first time Matt came out, we knew these guys would be the vendor we went with.

Their prices are competitive, but the real silver lining here is their entire team provides white glove service throughout the whole process. You can tell customer service and satisfaction is a top priority. The team always arrived on time and their communication around what is being done and why its being done is amazing.

Andrew D. | Seattle, WA | 2022

I was referred to this great company by "The Duct Cleaners," who had cleaned our air ducts in our new house but were unable to clean our absolutely filthy furnace.

Their guy showed up on the dot of 2pm, with their arrival window being 2pm - 4pm. I am a big fan of such punctuality! He was super nice and did an excellent job cleaning our furnace. The rates were reasonable and he got it done quickly. He used several different tools and items in order to do this job. So appreciative of this company!
