When Should Your Air Ducts Be Cleaned? 


A question often asked to our technicians is how often should I have my air ducts cleaned. The honest answer is, it varies system to system, based on the living environment of the home, and the customer’s needs and allergies. The Heating Ventilation and Air Conditioning (HVAC) system is vital for the health and cleanliness of your home. We usually spend 4-8 hrs a day sleeping in our homes. Having clean air inside your home to breathe greatly affects the health of the people inside of the home. Many systems we encounter have never been cleaned or inspected, and have significant amounts of dust, dirt, fecal matter, mold, fungus, bacteria, and dead animals inside them. This dust over time if left unsanitized or cleaned will always grow some form of bacteria which you can smell every time your system turns on, dust mites will call your dusty system home as well and be cycled throughout your system and home, and if this dust becomes moist, a dust fungus or mold can grow inside your system and seriously affect the health of the people inside the property. 

Ducts should be cleaned

Whenever:

➢ There is a visible amount of dirt or dust that has accumulated on returns 

➢ There is any amount of mold found in the system 

➢ Funky smells are coming from the system when it runs 

➢ The dust layer in your house won’t seem to go away for longer than a day or two

Common Types of Biotic Indoor Air Contaminants

Mold: There are 15 different types of mold that usually will grow within a residence. Mold is a type of fungus that grows primarily in dark and moist places. Metal air ducts in the basement are obviously a perfect environment for mold growth. If the ducts become dusty the smallest amount of moisture will cause the dust in the ducts to grow a fungus. The air movement from the system will cause these fungus spores to spread throughout the system and eventually into the home. It is not uncommon for our technicians to come across a mold outbreak within a system. Especially if the system has not been sanitized in the last year. 

Some quotes from https://www.cdc.gov/mold/faqs.htm on their informational page about basic facts about mold and dampness:


“Many building materials provide suitable nutrients that encourage mold to grow. Wet cellulose materials, including paper and paper products, cardboard, ceiling tiles, wood, and wood products, are particularly conducive for the growth of some molds. Other materials such as dust, paints, wallpaper, insulation materials, drywall, carpet, fabric, and upholstery, commonly support mold growth”


“In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people”

“Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies”


When mold is present in a system it is very important to have it cleaned and sanitized. A number of studies of indoor air quality have shown that the relationship between mold growth in a home and respiratory symptoms 

Fungi Spores: Molds thrive on moisture and reproduce by means of tiny, lightweight spores that travel through the air. This is how mold spreads throughout a system and possibly into damp areas in your house to grow. When you inhale tiny airborne mold spores, your body recognizes them as foreign invaders and develops allergy-causing antibodies to fight them. ... This reaction triggers the release of substances such as histamine, which cause itchy, watery eyes, runny nose, sneezing and other mold allergy symptoms. 

According to: https://www.mayoclinic.org/diseases-conditions/mold-allergy/symptoms-causes/syc-20351519

Dust Mites: Dust mites are microscopic arachnids (Spiders and Ticks family) that are invisible to the naked eye, and are commonly found in many places throughout the home. Fabrics, carpeting, upholstery, bedding, and drapery are some of the most common. Their fecal matter contain a protein that is toxic to humans, and in significant quantities, may cause illness. A walk across the carpet, or moving pillows or drapes will launch the dust mite fecal matter into the air where it may remain for up to 10 minutes. The particles will be sucked into the air ventilation system where these toxins will accumulate along with other dust and contaminants. When the system runs this fecal matter will be spread back throughout the home only to be cycled back through the air system making the problem worse and worse. A regular deep cleaning and sanitization is the only way to keep these contaminants out of your system.

Examples of Furnace and System

Cleaning Services

HVAC Deep Cleaning: A deep cleaning is a very thorough cleaning of the system. First we hook our negative air machine into the system by the furnace or directly into a trunk line. Our negative air machines are all gas powered and pull at a minimum of 5000 Cubic Feet Per Minute (CFM). Next, we go to each vent, cold air return, register, and trunk line individually and send a pressurized air whips on the end of a snake down each individual part of the system. The air whips kick and knock off all the baked on dust, debris, pet dander, bugs, batteries, drywall, etc. within the system and once the dust is loose the negative air machine (which runs the entire time) vacuums it all out. With the pressurized air, we are able to guide the dust and debris towards the negative air machine. This process pulls all of the dirt that is in the system out. Leaving the system perfectly clean with nothing left behind.

Furnace Blower Cleaning: Cleaning the blower of the furnace is the most important part of keeping a system clean and healthy. The blower is what pushes all of the air through the property, so when you have a dirty blower you will usually get a dirty system soon after. When we clean the blower unit we clean all the components, we scrub the motor and fan blades, we beat the carpets out with the air whips, we blow out the heat exchange, and wipe down the burners. We recommend having your furnace cleaned every 2-3 years. Again it is the most important part of the system to keep clean. Remember that

Dryer Vent Cleaning: Cleaning your dryer vent is an essential part of home maintenance. Having a clean dryer vent pipe is essential for the dryer to work at its peak efficiency. Many times when a dryer is taking longer than normal to dry your clothes it is due to a dirty dryer vent pipe. If neglected you might even end up with clogged pipe and then you are at high risk for a fire. We recommended cleaning the dryer vent piping every 1-3 years depending on build and use. 

Sanitizing: System sanitization is the only way to prevent allergies, bacteria, dust mites, and fungus/mold from growing inside the dust of your air system. Many homes our technicians clean, have some form of dust fungus growing inside the blower compartment, trunk lines, or vents. This fungus will cause health problems for the residents of the home and can lead to a mold outbreak within the air system of the house. The only way to prevent or treat this fungus is to have a sanitizing solution sprayed in the system periodically. When we sanitize a system we make sure we sanitize the whole thing. Our process is that we use a fogger which foggs out the two natural sanitizers that we use. We turn your system on and fog in through the return side. This fog is then pulled through the returns by the blower into the furnace. The blower then pushes the fog through all the components of the furnace sanitizing the furnace completely and then into all of the vents of the home. Our company performs a full system sanitization not just a vent of unit sanitization. We sanitize every part of the system.
