Residential Duct Cleaning

Residential

Your duct system functions as the respiratory system of your home. When it becomes contaminated and congested, it should be cleaned so it can 'breathe' normally and efficiently.

Maintaining clean heating, ventilation and air-conditioning (HVAC) systems is an important part of sustaining acceptable indoor air quality (IAQ). When an HVAC system is a source of contaminants introduced into occupied spaces, properly performed system cleaning services should take place to reduce or eliminate contaminant introduction.

Contaminants in HVAC systems may take many forms. Common contaminants include dust particles, active bacterial or fungal growth, debris from rusted HVAC components, man-made vitreous fibers, mold spores, and other items.

What You Should Know About Residential Air Duct Cleaning

Your HVAC system and air ducts should be cleaned for the same reason that your home needs cleaning. Suppose that your home had not been cleaned for three to five years? Most homeowners keep very clean homes and they cannot believe what is commonly found in HV AC systems. Even new homes have air ducts that are filled with construction debris. It is recommended that HVAC systems be cleaned every three to five years.

A five-year study conducted by the Environmental Protection Agency (EPA) showed that indoor air pollutant levels exceed outdoor levels by 200 to 500 percent. Many hazardous contaminants, such as mold spores, fungi, bacteria, pollen, animal dander, etc. have the potential to affect your health. Harmful contaminants are pulled into air ducts where warmth, darkness and humidity create a breeding ground for these contaminants. Your HVAC system will continue to disperse these contaminants back into the air that you breathe. The removal of such contaminants from the HVAC system and home should be considered as the first step in an overall plan to improve indoor air quality.

Research conducted by the EPA and Louisiana State University has shown that removal of debris that builds up inside HVAC systems can improve airflow up to 20% or more. This means that your system should not have to run as long to do the job it was intended to do. Running your system less will reduce energy bills.

There are several factors that could affect the time needed to clean a residential HVAC system. These factors include the type of home, accessibility of ductwork, number of systems, and amount of ductwork circulating the air in your home. Average size homes require 3 to 4 hours for two technicians. Our technicians will stay as long as necessary to thoroughly clean the entire system(s).

The most effective way to clean air ducts and ventilation systems is to use a vacuum system that is strong enough to remove all the harmful debris that has accumulated in the HVAC system. The most powerful vacuum systems are truck-mounted systems that place your ductwork under negative pressure up to 10,000 cubic feet of air per minute. While the vacuum draws the air through your system, various devices are inserted into the ducts to dislodge the debris that is contaminating your system. These devices include whips, brushes, and "skipper balls", etc., most of which are powered by compressed air of up to 200 psi. Duct Doctor technicians are trained to select the proper tool designed for your particular type ductwork. In some rare instances, it may not be practical to run our vacuum hose from the truck-mounted system. In those cases, for example in a high-rise apartment building, we may bring a large portable unit right to the system. Our portable units are powerful enough to do the job.

The Environmental Protection Agency says that "duct cleaning services typically - but not always - range in cost from $450 to $1,000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climactic region, and level of contamination."

Sanitizers are anti-microbial chemicals applied to the interior surface of the air ducts and are designed to control microbial contamination. Before any sanitizers are used, the system should be thoroughly cleaned. It is critical that any anti-microbial treatment used in your system be EPA registered for use in HVAC systems. Ask to see the chemical's Material Safety Data Sheet (MSDS). It should be noted that there are no EPA registered anti-microbial products for use on porous system surfaces - such as fiberglass surfaces.

NADCA members have signed a Code of Ethics stating they will do everything possible to protect the consumer, and follow NADCA Standards for cleaning to the best of their ability. Air duct cleaning companies must meet stringent requirements to become a N ADCA member. Among those requirements, all NADCA members must have a certified Air System Cleaning Specialists (ASCS) on staff who have taken and passed the NADCA Certification Examination. Passing the exam demonstrates extensive knowledge in HVAC design and cleaning methodologies. (For more information, go to the NADCA web site)

Consumers should beware of 'blow-and-go' firms who use scare tactics and bait you with cheap prices for "whole house duct cleaning". Most of these type firms send one person with no more than a shop vac. Before you agree to let these people into your home, we suggest you call them back and ask the following questions:

1. What is your procedure and what kind of equipment do you use to clean my ductwork?
2. How long do you estimate that it will take to properly clean my ductwork?
3. Are you a member of the National Air Duct Cleaners Association (NADCA)?
4. Will your price change once you arrive at my home?

Light Commercial Duct Cleaning

Commercial

Duct Doctor has extensive experience working with building engineers and construction managers to meet their Air Duct Cleaning needs. We have successfully worked with leading mechanical contractors, construction companies, government agencies, and healthcare facilities to solve their indoor air quality problems.

With companies today paying closer attention to environmental issues, poor indoor air quality can pose a great threat to human health. The United States Environmental Protection Agency has labeled poor indoor air quality as a high risk given the different types of contaminants, bacteria, mold, dust, and other harmful particles that are often resident in a building. The HVAC system, of course, plays a critical role in the indoor air quality in a building. It is logical, then, that dirty air ducts should be cleaned- especially in environments where indoor air quality is a top concern.

Commercial

In order to maintain acceptable indoor air quality (IAQ), it is commonly recommended that mold, fungi, dust and other contaminants be cleaned out of the HVAC system. Cleaning HVAC systems provides many benefits. Cleaning lessens the likelihood of indoor air pollution in the building and may help to alleviate health and comfort complaints by occupants. Clean HVAC systems perform more efficiently, which may decrease energy costs. Well-maintained mechanical components are likely to last longer, reducing the need for costly HVAC system replacement or repairs.

Air Duct Cleaning provides a cost-efficient and practical solution to ensure the air circulating in an HVAC system is free of airborne contaminants. Having your Air Duct System cleaned will both remove potential health hazards and create an un-congested duct system that will help your HVAC system run more efficiently.

Dryer Vents

Dryer vent Fire

A clothes dryer works by forcing hot air through a turning drum. Wet clothes placed in the drum are then dried by the moving hot air. It is possible for a full load of wet clothes to contain as much as one and a half gallons of water. Lint is created from the clothes as the water is removed and the clothes dry. While much of the lint is trapped by the dryer's filter, lint also is carried through the venting system, together with moist air. The accumulation of lint, both in the dryer and in the dryer vent, reduces the airflow and creates a highly flammable fuel source.

In addition to the accumulation of lint, blockage in dryer exhaust vents also can occur from the nests of small birds and animals or from bends in the venting system itself. A compromised vent will not exhaust properly to the outside. Overheating may result. If enough heat is produced to ignite the lint itself or nearby combustible items, such as the clothes in the dryer or combustibles left nearby, the engineered safety mechanisms are compromised and fire ensues.

In most cases, clothes dryer fires can be prevented. "Failure to clean" is the number one factor contributing to clothes dryer fires, followed by mechanical and electrical failure. Clogged dryer vents occurring from lint buildup may make the dryer operate incorrectly and raise the temperature of the dryer machinery high enough to ignite lint or nearby combustibles. The exhaust vent should be as short as possible and have limited bends to allow sufficient airflow. Improper items placed in the dryer, such as plastic, foam, or other synthetic materials also can increase the risk of fire. Make sure to follow the recommended safety tips for operating clothes dryers safely.
