How Is a Duct Cleaning Done?
Posted On: February 15, 2019
Nobody wants to live in a dirty, dusty house, and there are numerous things that can make a house dusty. One of the most common causes are dirty ducts; this is especially true if the homeowner lives in an older home.
Even if the homeowner has invested in custom ductwork, they need to regularly maintain the ducts. Before calling an HVAC cleaner, the homeowner should take the time to learn about the cleaning process.
1. Thoroughly Inspect the Ducts
When cleaning ducts, the first step is to thoroughly inspect the system. This can be done with the naked eye, however, many HVAC cleaners will utilize probing cameras.
This useful tool allows the HVAC cleaner to get a look at hard-to-see areas in the system. A probing camera also allows the HVAC cleaner to inspect the system for any damage or leaks.
2. Negative Pressure
The next step in the duct cleaning process is creating negative pressure. To do this, the HVAC cleaner needs to connect a vacuum collection device to what is known as the air handler.
After this has been completed, the cleaner needs to seal all of the registers. Once this is done, the HVAC cleaner turns on the vacuum; this creates a negative pressure within the ducts.
3. Uncover the Registers Individually
After the HVAC cleaner creates negative pressure, they will then have to clean each register individually. To do so, they will remove the seal.
This gives the HVAC cleaner the ability to clean each duct. Remember, professional HVAC cleaners will use high-quality tools to efficiently clean the ducts.
4. Finish Off the Rest of the System
The final step of the HVAC cleaning process is cleaning the rest of the system. This includes aspects like the drain pan, blower motor, and the evaporator coil. Giving these features a good cleaning will ensure that the system will perform at its full potential for years to come.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
