Indoor Air Quality


Indoor Air Quality 2

Have you been sneezing too much recently? Are you experiencing runny nose frequently? Are your employees having hard time concentrating or performing efficiently?

If the answer is yes, it might have something to do with the maintenance of your HVAC system!

According to United States Environmental Protection Agency (EPA) central HVAC systems can collect pollution if they are not maintained and cleansed regularly which can make the air indoor 2 to 5 times more polluted than the air outdoor! IAQ is ranked among the top 5 environmental public health risks by this organization.

Occupational Safety & Health Administration (OSHA) also considers inadequate HVAC maintenance as a major cause of poor indoor air quality which can cause concentration difficulty, fatigue, headaches, skin rashes and eye, nose, throat and lung irritation.

Research data conducted by The American College of Allergy, Asthma & Immunology shows that 50% of all illnesses are either caused or aggravated by poor IAQ.

At Fairfax Mechanical, we offer indoor Air Quality (IAQ) services for HVAC owners in North Virginia to help you breathe the cleanest air possible inside your own property along with your family, employees and clients.

AS part of any high quality HVAC system is the air filtration system which places high tech HEPA filters over vent coverings in order to capture pollutions and contaminants of any kind. The HEPA filters are built from several layers to ensure that no allergen or pathogen can pass through.

Proper ventilation is important to maintain the right ratio of gases to ensure not too much carbon dioxide is in the air you breathe. It might be achieved by remodeling ductwork and vent coverings, adding make-up air or reconfiguring your HVAC settings.

Air humidification is critical in terms of both adding and removing moisture. Too much moisture can lead to mold build up that spread to other areas. Too little moisture can lead to dryness and spread of dust and mites. Central humidifier is a critical part of any HVAC system.

Air purification is possible with the help of air purifiers to remove microorganisms from the air by the use of both an advanced HEPA filter for larger particles and electrostatic fields for microscopic particles. Ultraviolet ray air purifiers are also available to destroy microbial particles without using any physical filter.

According to EPA there are many pollutants in the environment resulted from particulate emissions, building materials, fabrics, moisture and pesticides, just to name a few. If they get trapped inside your HVAC system, they will be circulated with the air that is flowing into your rooms. The health effects might be immediate after exposure like allergy symptoms or it may show up years later as a chronic disease like lung or heart issue.

As scary as it sounds, there is a solution for this problem and it is called Duct Cleaning!

We are expert at HVAC systems and Duct Cleaning in order to optimize your health and maximize the performance of your HVAC which will also lead to a decrease in your energy bill!

How is Duct Cleaning performed?

Duct cleaning is the process of removing pollutions from your entire HVAC system with more emphasize on ductwork, filters and humidifier.

It starts by covering the vent coverings in order to prevent any debris from leaking into your rooms. Flooring and any surface that might be affected is covered too.

An industrial air pressure vacuum containing HEPA filters is connected to your ductwork from the outside.

The vacuum pulls the dust and debris collected in your ductwork into a truck.

The ductwork is inspected by our experienced staffs to confirm the result.

The equipment cabinets of your HVAC system are inspected and cleaned as well with more focus on coils that either absorb or release heat and moisture from the air which makes them an ideal place for dirt collection.

Any water leak is fixed and resulting mold is removed accordingly. If necessary, chemical solutions are used safely to remove molds.

Refrigerant leak is also corrected which is extremely harmful.

Most importantly, the filters are replaced with a new set.

Advantages of Regular Duct Cleaning:

  • Prevents buildup of pathogens and allergens
  • Reduces asthma and allergy symptoms
  • Increases your lifespan
  • Increases HVAC performance
  • Reduces energy bill
  • Reduces HVAC repairs
  • Increases HVAC lifespan
