How Is a Duct Cleaning Done?

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.

by Rita, Scarborough on Twintech Heating and Cooling
We were so pleased with their service

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Within a couple of hours, we had a new unit up and running!

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.

Professionally done and took care to cover all entry floors

Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.

by Bill, Pickering on Twintech Heating and Cooling
Proud to support this local company

Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.

by Taz on Twintech Heating and Cooling
