FAQ

 

Why should I clean my air ducts?

There are a number of reasons why you should clean your air ducts . Heating and Air Conditioning Systems have been shown to be a source of a variety of contaminants that have the potential to affect your health. These contaminants include such things as mold, fungi, bacteria, pet dander and dust, all of which accumulate in your HVAC System over time. The removal of these contaminants from your homes heating and cooling system should be considered a major part of your overall plan to improve indoor air quality and ensure the safety of your family, employees, or customers.

How often should I clean my air ducts?

The frequency of air duct cleaning depends on several factors, smokers or pets in the home, water contamination, residents with allergies or asthma, after renovations or prior to moving into a new home all are factors in determining when and how often a Heating and Air Conditioning system should be cleaned. Our general rule of thumb is an air duct system could be cleaned as often as every two years but no more than five years should elapse between cleanings.

How do you clean a residential air duct system or central air system?

We use gas Power Vacuums and HEPA Negative Air Vacuum Machines. These vacuums place the system under negative air pressure. We then use dislodging equipment to knock loose the dust, dirt, and debris from the duct walls. Once the debris is airborne, the vacuum is able to remove it. Our cleaning includes the entire Air Handling System. View our steps to professional air duct cleaning.

Are there any health benefits that come from HVAC system cleaning?

Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.

Will HVAC system cleaning reduce our home energy bills?

Research by the U.S. EPA has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to break down, have a longer life span, and generally operate more effectively than dirty systems.

How should a residential HVAC system be cleaned?

The most effective way to clean air ducts and ventilation systems is to employ Source Removal methods of cleaning. This requires a contractor to place the system under negative pressure, through the use of a specialized, powerful vacuum. While the vacuum draws air through the system, devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home.  What kind of equipment is best for cleaning-truck mounted vacuums or portable vacuums? 
There are two main types of vacuum collection devices: (1) those mounted on trucks and trailers, and (2) portable units. Truck/trailer mounted gas motor equipment is generally more powerful than portable equipment. However, portable equipment can often be brought directly into a facility, allowing the vacuum source to be located closer to the ductwork. Both types of equipment will clean to NADCA standards. All vacuum units should be attached to a collection device for safe containment prior to disposal. Any vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.
 A vacuum collection device alone will not get an HVAC system clean. The use of methods and tools designed to agitate debris adhered to the surfaces within the system, in conjunction with the use of the vacuum collection device(s), is required to clean HVAC systems. (For example: brushes, air whips, and “skipper balls.”)

 

How often should residential HVAC systems be cleaned?

Frequency of cleaning depends on several factors, not the least of which is the preference of the home owner. Some of the things that may lead a home owner to consider more frequent cleaning include:

  • Smokers in the household.
  • Pets that shed high amounts of hair and dander.
  • Water contamination or damage to the home or HVAC system.
  • Residents with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in the home’s HVAC system.
  • After home renovations or remodeling.
  • Prior to occupancy of a new home.

What is the normal price range for the air duct cleaning service? The Environmental Protection Agency says that “duct cleaning services typically – but not always – range in cost from $450 to $1000 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” and type of duct material. Consumers should beware of air duct cleaning companies that making sweeping claims about the health benefits of duct cleaning – such claims are unsubstantiated. Consumers should also beware of “blow-and-go” air duct cleaning companies. These companies often charge a nominal fee and do a poor job of cleaning the heating and cooling system. Most of them will not use the right equipment or will use poor cleaning techniques.

What are sanitizers, and why would they need to be used?

Sanitizers are anti-microbial chemicals applied to the interior surface of the air ducts, 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 the intended use in HVAC systems.

How long should it take to clean a typical residential HVAC system?

The amount of time it takes to clean a residential HVAC system depends on many variables such as the size of the home, the number of systems, the extent of the contamination and the number of HVAC cleaners performing the job.
