How Does Air Duct and Vent Cleaning Work?
Have you observed your home getting dusty more quickly than normal recently? Are your energy bills slowly creeping up each month? Dirty ductwork and A/C system components may be to blame. If your home is older, has experienced considerable water damage, or just hasn't had duct cleaning recently, consider employing a reputable, professional duct cleaning company, like ours, to clean your house's ductwork.
The proper method uses negative pressure technology. Negative pressure duct cleaning is a systematic, straightforward process that delivers clear results, but less-than-reputable, unprofessional companies have actually given the process a bad reputation the last few years.
If you have had your ducts cleaned by a company that was in and out in an hour and appeared to leave more dust and dirt than they removed, you were most likely left wondering exactly what, if anything, was done. To combat these unfavorable experiences, legitimate duct cleaning contractors, like All Pro Air Duct Cleaning, are eager to educate house owners about the National Air Duct Cleaning Association's (NADCA) standardized methods for vent cleaning services. These procedures outline how to effectively clean ducts in addition to registers, filters, plenums, evaporator coils, and air handlers, practically every component of a forced-air HVAC system, and the results will be apparent.
The techniques utilized by accredited specialists are called source-removal strategies by NADCA, and they include cleaning the ducts by hand and with compressed air tools while a vacuum collection gadget extracts dislodged dust and particles. The process generally follows these steps:
Step 1: Examine the ducts
A simple, visual inspection of the ducts leading to the return and supply vents is necessary for two reasons. Initially, it's a step that you can take yourself to evaluate the level of accumulation in the ducts in advance and verify the difference after they have been cleaned. We actually have cameras that can probe even further into the ducts and show the complete extent of the buildup prior to cleaning.
Second, a professional duct cleaning provides a chance for the technician to check the ductwork for leaks or, in the case of flexible ducts, kinks. We make duct repairs and replace broken ductwork if an issue is discovered.
Step 2: Develop negative pressure.
Duct cleaning professionals use large, portable or truck-mounted vacuums to draw dust and debris out of your ductwork. However, prior to switching on the suction and scrubbing the ducts, we perform a couple of initial steps.
Initially, we hook the vacuum up to large hose pipe to a duct near the air handler, which is the heart of your HVAC system. The service technician will cut an access to hole in the duct, place the vacuum tube, and seal where they join as securely as possible. Your HVAC system consists of a supply side and a return side, ducts that send treated air into the rooms of the house, and ducts that return air to the air handler. The supply side and return side are separate, and the duct cleaning process needs to be performed on each..
Next, the technician must seal each register with an adhesive cover. This is a crucial step due to the fact that even a very powerful vacuum will be ineffective if the registers in each room of the house are uncovered.
Once the technician completed these preparatory steps, he or she will switch on the vacuum unit. This action develops negative pressure, and particles inside the ductwork will be sucked into the collection gadget as they're brushed or blown loose.
Action 3: Agitate the dust.
As soon as the system is under negative pressure, the service technician will find each register and clean the ducts one by one. One thing that identifies a NADCA-certified duct cleansing professional from a fly-by-night is the amount of time each spends at each register.
Poorly-trained professionals have been trained to leave after a quick burst from an air compressor and a spritz of disinfectant. This method is largely ineffective and usually results in dust being blown back into the room. Genuine specialists will utilize spinning brushes, compressed air tools, and a strong vacuum to ensure dust is removed and sucked into the vacuum collection device.
Step 4: Clean the rest of the system.
NADCA suggests cleaning up the other parts of the HVAC system too, including the air handler's blower motor, evaporator coil, and drain pan.
Cleaning these components, in addition to cleaning or changing the filter, will enhance the air quality in your home along with extending the life and increasing the performance of your HVAC system.

The Bottom Line.
Does negative pressure duct cleaning work? Yes! However it needs to be done correctly and by certified experts.
NADCA mentions that an extensive cleaning should take three to 5 hours. While this service might cost more than what an uncertified contractor charges for a quick cleaning, the results of a cleaning carried out according to NADCA's best practices will justify the time and cost. A properly trained contractor will carry out the task completely and thoroughly, ensuring that your ductwork end ups clean and intact.
