Duct and Vent Cleaning: What Is Completed?
Have you noticed your house getting dusty more quickly than usual lately? Are your utility bills slowly creeping up every month? HVAC system components and ductwork may be to blame. If your house is older or has undergone significant water damage, consider hiring a professional duct cleaning company to clean your home’s ductwork.
How is air duct cleaning done?
The right method uses pressure technology. Pressure air duct cleaning is a systematic, straightforward process that deliver outcomes, but less-than-reputable companies have given the industry a bad rap in recent years.
If you have had your ducts cleaned by a company that was in and out in an hour and seemed to leave more dirt and dust than they actually eliminated, you were probably left wondering what, if anything, was done.
To combat these negative experiences, legitimate duct cleaning contractors are happy to educate homeowners about the National Air Duct Cleaning Association’s (NADCA) standardized methods for cleaning services.
These procedures establish how to properly clean ducts in addition to registers, filters, plenums, evaporator coils, and air handlers–almost every part of a forced-air HVAC system–and the results will be evident.
The methods employed by licensed contractors are called source-removal techniques by NADCA, and they involve cleaning the ducts by hand and with compressed air tools while a vacuum collection device extracts dislodged dust and debris.
Read on to understand more about the duct cleaning industry’s best practices.
How Duct Cleaning Works
Step 1: Inspect the ducts
A simple visual inspection of the ducts leading to the return and supply registers is important for 2 reasons. It’s a step that you can take to assess the level of buildup from the ducts beforehand and confirm the gap after they have been cleaned.
(A duct cleaning contractor will probably have cameras that can probe even farther into the ducts and reveal the entire extent of the buildup before cleaning.)
Second, a professional duct cleaning is an chance for the technician to inspect the ductwork for leaks or, in the case of flexible ducts, kinks. Duct cleaning contractors can also make repairs and replace ductwork.
Step 2: Create negative pressure
Duct cleaning contractors use large, portable or truck-mounted vacuum collection devices to suck up dust and debris from your ductwork. Before turning on the suction and scrubbing the ducts, the technicians must perform a few steps that are preliminary.
First, they need to hook the vacuum collection device’s large hose to a duct near the air handler–the center of your HVAC system. The technician seal where they combine as closely as possible, insert the vacuum hose, and will just cut an access hole in the duct.
(Note that your HVAC system contains a supply side and a return side–ducts that send treated air into the chambers of the house, and ducts that return air to the air handler. The supply side and return side are different, and the duct cleaning procedure must be done on each.)
Next, the technician should seal each register with an adhesive cover. This is an important step because an vacuum collection device if the registers in every room of the house are uncovered will be ineffective.
When the technician completed these preparatory steps, he or she will turn on the vacuum . Pressure that is negative is created by this step, and particles within the ductwork will be sucked into the collection device since they’re brushed or blown.
Step 3: Agitate the dust
When the machine is under negative pressure, the tech will uncover each register and clean the ducts one . 1 thing that distinguishes a duct cleaning contractor is the period of time each spends per register.
Improperly trained technicians have been known to proceed after a quick burst from an air compressor and a spritz of disinfectant; this technique is largely ineffective and generally results in dust being blown back into the room.
Legitimate technicians will use rotating brushes, compressed air tools, and simple vacuum cleaners to ensure dust is dislodged and sucked into the vacuum collection device.
Step 4: Clean the rest of the system
NADCA recommends cleaning the other elements of the HVAC system as well, including the air handler’s blower motor, evaporator coil, and drain pan.
Cleaning these elements, together with cleaning or changing the filter, will improve the air quality in your house as well as extend the life and increase the efficiency of your HVAC system. To discover more about these tasks, read our care strategies.
The Most Important Thing
Does negative pressure air duct cleaning work? Yes! But it must be done by qualified professionals and correctly.
NADCA states that a thorough cleaning should take three to five hours. The results of a cleaning done according to the best practices of NADCA will justify the cost and time Although this service might be more expensive than what contractor charges for a brisk cleaning.
A properly trained contractor will perform the job thoroughly and carefully, ensuring that your ductwork winds up clean and undamaged. Hire a Best duct cleaning contractor to ensure that you get a service that meets the industry standard for quality.
