Duct Cleaning

How to select an air duct cleaning company?

There are health advantages for all residents from frequently cleaning the Heating, Ventilation, Air Conditioning (HVAC) Method.

Heating, ventilation, and air conditioning (HVAC) systems gather mold, fungi, bacteria as well as a variety of contaminants that reduce the high quality of the air residents and guests breathe. A dirty air duct contributes to poor indoor air high quality and impacts the wellness of individuals within the residence.

The objective of residential air duct cleaning is always to remove these contaminants from a home’s HVAC program to acquire the very best indoor air top quality.

Probably the most successful way to clean an air duct and/or ventilation system is always to use a specialized, powerful vacuum which puts the air duct / ventilation program under negative stress. Whilst the vacuum draws air via the program, devices are inserted in to the ducts to dislodge contaminants and debris from the interior surfaces, moving the contaminants/debris from the home’s air ducts and ventilation systems in to the vacuum.

Vacuum collection alone doesn’t clean the HVAC method. Brushes, air whips, “skipper balls” as well as other tools that agitate contaminants and debris scrub the surfaces within the air duct system and propels contaminants and debris in to the vacuum collection device(s).

Anti-microbial chemical sanitizers are applied towards the interior surface of the air ducts to control microbial contamination…but…prior to sanitizers are used, the program should be thoroughly cleaned. All anti-microbial chemicals used need to be EPA registered for use in HVAC systems. Ask to find out the chemical’s Material Security Information Sheet (MSDS). If you are still concerned, contact the EPA at 1-800-438-4318. You’ll find no EPA registered anti-microbial goods for use on porous method surfaces – such as fiberglass surfaces.

When sanitizing air ducts you would like to produce sure the air duct cleaning organization utilizes protected; successful EPA approved products which can be safe for people, pets, and the environment. An atomizer fogs the sanitizing solution all through the complete ventilation method.

Allergic people, infants and elderly are specifically sensitive for the microbes that trigger respiratory difficulties like bacteria, mildew, fungi algae and dust mites which need a highly-effective sanitizer to eradicate odor-causing microorganisms as well contaminants associated with allergies, mildew and bacterial growth. Make certain the sanitizer is rated by the EPA as a category IV item with all the lowest toxicity rating. Sanitizing air ducts indicates toxicity and security safeguards that establish and make certain you will find no dangerous dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects in the products.

There are two well-known types of vacuum collection systems…these mounted on trucks and trailers versus portable units. Truck/trailer mounted equipment is generally a lot more powerful than transportable equipment. By contrast, portable equipment usually could be brought straight into a facility, locating the vacuum closer to the ductwork. Both kinds of gear clean to air duct industry standards. Vacuum units ought to be attached to a collection device for secure containment before disposal. A vacuum collection device which exhausts indoors should be HEPA (high efficiency particulate arrestance) filtered.

The frequency of air duct (HVAC) cleaning is determined by a number of factors:

*before occupying a brand new house.

Extended Equipment Life 9 out of 10 method failures are caused by dirt and dust according towards the Louisiana Cooperative Extension Service. One from the functions in the fan, located inside of your air handler, is to keep the heat exchanger cool. Accumulated dirt and debris can minimize the CFM (cubic feet of air per minute) as significantly as 50%! This is essentially the most common cause of cracks in heat exchangers. Having your HVAC program cleaned may prevent pre-mature breakdown & aging of your heating and cooling system.

Decrease Dusting Air duct cleaning helps to minimize household dust by removing the dust where it travels most – via your air duct program.

Energy Savings According towards the EPA, a buildup of only.042 inches of dirt on a heating coil can result in a decrease of efficiency of 21%. A clean air conveyance method may help to increase efficiency and therefore may help to minimize heating and cooling costs.
