Since these are tightly assembled, it is rare that stale air or fresh air will circulate at the same time. If this occurs, then there may be accumulated pollutants in the air ducts. This will typically create air that is unhealthy for everyone living in the home. Subsequently, these same pollutants will become irritants, negatively impacting the health of the occupants of the building. In many cases, people will suffer from respiratory conditions and in other cases, the pollutants could likely cause damage to the home. Reducing or Eliminating Pollutants When you clean the HVAC air ducts, it will drastically eliminate or reduce the pollutants, creating healthier air and improving the health of the occupants. There are several suggestions for air duct cleaning. However, it is best to hire a HVAC contractor with more knowledge about the best practices for air duct cleaning.

In so doing, the project will be done more properly and it will reduce the appearance of annoying rodents. The disadvantage of air duct cleaning if you do this yourself is that you could ultimately damage the air ducts. So, to improve the air quality in your home, it is strongly recommended to get professional assistance. The HVAC technician will be able to tell when your next duct cleaning will be necessary. It is especially important, though, to know as much as you can about air duct cleaning so as to establish the one that is ideal for you. best cleaner for worn wood floorsWhile you will be relying on a professional HVAC contractor, you will still have personal knowledge about what is involved and the methods used.best vacuum cleaner 2013 review The most common methods used for air duct cleaning over the years is industry standard. dryer vent cleaning requirements

As time goes on, advancements are being made to continue improving the methods involved in the process. However, for now, the methods employed are as such: Power Vacuum or Air Sweep – this is a meticulous method of duct cleaning, although, more expensive. It does the best job of removing dirt in an extremely careful manner. Point of Contact – while this may not be as thorough as the air sweep method, it is safer for the vents and air ducts. best way to clean leather car seats bmwIt is also less expensive, but still uses a vacuum, and spinning brush as the best cleaning tools Removing the Source – this is the most common of all three methods for air duct cleaning. Mechanical agitation loosens the dirt and debris and extraction helps to remove everything entirely in a safe manner. Methods of air duct cleaning have been around since the 1900s. However, the techniques have evolved since that time due to the work done by knowledgeable and experienced HVAC contractors.

When you hire a professional HVAC technician, you stand a better chance to have improved air quality in your home.

However, you might not know it from watching cheap, fly-by-night duct cleaning contractors work. Their spurious methods often take a fraction of the time as an accredited professional’s, and disappointing results can leave a homeowner wondering exactly what, if anything, was done. Unlike their industry’s outliers, legitimate duct cleaning contractors are eager to educate homeowners about the National Air Duct Cleaning Association’s (NADCA) standardized methods. These procedures establish how to properly clean ducts as well as registers, filters, plenums, evaporator coils, and air handlers—almost every component of a forced-air HVAC system—and the results will be obvious.

The methods used by accredited 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. A simple visual inspection of the ducts leading to the return and supply registers is important for two reasons. First, it’s a step homeowners can take themselves to assess the level of buildup in the ducts beforehand and confirm the difference after they’ve been cleaned. (A duct cleaning contractor will likely have cameras that can probe even farther into the ducts and show the full extent of the buildup prior to cleaning.) Second, when a professional performs the inspection, it affords an opportunity for the technician to check the ductwork for leaks or, in the case of flexible ducts, kinks; many duct cleaning contractors are also capable of making repairs and replacing ducts.

Basically, duct cleaning contractors use large, portable or truck-mounted vacuum collection devices to suck dust and debris out of your ductwork. However, before turning on the suction and scrubbing the ducts, the technicians must perform a few preliminary steps. First, they must hook the vacuum collection device’s large hose to a duct close to the air handler—the heart of your HVAC system. The technician will simply cut an access hole in the duct, insert the vacuum hose, and seal where they join as tightly as possible. (Note that your HVAC system includes 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 must be performed on each.) Even an extremely powerful vacuum collection device will be ineffective if the registers in each room of the house are uncovered, so the technician should seal those with adhesive covers.

Turning on the vacuum will now create negative pressure, and particles inside the ductwork will be sucked into the collection device as they’re brushed or blown loose. Once the system is under negative pressure, the technician will uncover each register and clean the ducts one by one. One thing that distinguishes a NADCA-certified duct cleaning contractor from a fly-by-night is the amount of time each spends per register. Improperly trained technicians have been known to move on after a quick burst from an air compressor and a spritz of disinfectant; this technique is largely ineffective and usually 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. NADCA recommends cleaning the other components of the HVAC system as well, including the air handler’s blower motor, evaporator coil, and drain pan.
