If you are a regular customer of Lehigh HVAC or have scheduled consultations with our team, you might notice that we pay attention to duct cleaning. You might have heard our technicians state that HVAC duct cleaning keeps both your equipment and your loved ones healthy. That’s actually more important than many people realize.
HVAC ducts are one of the most critical components of a heating and cooling system. They carry the conditioned air to the rooms where it is needed. These ducts, if they develop cracks and leaks, can render the entire HVAC unit non-functional, ultimately costing you labor hours to find the exact cause of what restricts the system from delivering the desired comfort. In this post, we will present the complete, step-by-step duct cleaning process we follow at Lehigh HVAC Projects.

Though the exact process varies by duct type and equipment, here is a standard process we follow at Lehigh HVAC. Additional steps might be required in some special scenarios.
The technicians prepare the site for easy access and hassle-free cleaning of ducts. All the associated components are inspected and brought ready for easy access. Furthermore, all the furniture items and the household items are removed if they are surrounding the ducts or creating hurdles in the pathway.
Technicians apply negative pressure to the ducts to prevent the loose buildup from floating inside rooms. Instead, this debris is collected in a separate collection unit. This negative pressure is applied through a heavy-duty, truck-mounted, or HEPA-powered vacuum system.
The technicians access the entryways for the ducts by locating the holes in the ducts that are later filled with metal sheets or plugs. Once these holes are found, the technicians access the ductwork and begin the cleaning process.
The technicians use brushes, air whips, and compressed air tools to agitate and remove the debris settled inside the ducts. The technicians start from the farthest point and bring the debris towards the main trunk, step-by-step.
They wash, clean, and reinstall registers and grilles. They also clean and remove debris from other accessible components, such as blower motors, fan blades, and evaporator coils.
If algae or fungal colonies are found inside the ducts, some optional treatments, including the use of chemical-based sprays and cleaning agents, are required. This treatment removes the unpleasant odors from the system and prevents the risk of mold and mildew spores circulating inside the rooms.
The job is not completed after cleaning all components. Technicians are also responsible for doing some post-service chores as part of their duties.
Here is what you can expect.
Technicians seal the access points and covers once they are sure cleaning went as it was intended. This step also includes assembling the dispersed HVAC components to give them their final form for operational efficiency.
Before the technicians leave your site, they run a final commissioning of the system to confirm if it now works as intended. If some errors or flaws are noticed in the operation, they review the whole system and apply the troubleshooting steps. At the end, you can expect to get a fully operational, smooth-performing HVAC system.
When was the last time you got your HVAC ducts cleaned? If the answer is over 3 years, this is the right time to get them cleaned now. It boosts system performance and reduces the risk of fungal infections in your family. To learn more about our duct cleaning system, pricing, and process, feel free to book an appointment.
