They can include; mold, fungus, bacteria, dust particles, and yes rodents and droppings. The removal of such contaminants from the homes air circulation system is an essential step in improving your indoor air quality.

How do I know if my dryer vent needs to be cleaned?

Clothes should generally dry in one drying cycle. If they do not the dryer is most likely not venting properly.

Turn on your dryer and find the exhaust on the outside of the building, if air flow is weak or non-existent, then it needs to be cleaned or repaired.

Many times a burnt out heating element is a sign that the dryer overheated due to improper venting, or restricted airflow.

How do I know if my HVAC system is in need of cleaning?

Furnace and air duct cleaning is recommended when:

  • Residents with allergies or asthma are agitated by the indoor air quality.
  • There are high levels of dust in your home no matter how much you clean.
  • You inspect your furnace and air filter, and it is visually dusty and dirty.

What are the building code requirements for dryer vents?

Building code for dry vents states that they are not to exceed 14′ and two 90 degree elbows before exiting the building. If they exceed this criteria they are required to have a booster fan installed, these greatly improve the ability to exhaust, but still require cleaning.

What are the components of my HVAC system?

HVAC stands for Heating Ventilation and Air Conditioning.  The return air ductwork “returns” air to the furnace to be filtered and pulled through the fan. Where it then pushes air over the heating element or cooling coils. The air then flows through the supply side ductwork where it “supplies” the home with cleaner temperature altered air for your indoor comfort.

What is the price range for air duct cleaning services?

The EPA says “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.”

Generally a small cabin starts around $500, and a large house with a single HVAC system can be about $1500.

Will having my HVAC system cleaned improve efficiency?

Research by the U.S. EPA has shown that cleaning of the HVAC system allows system to run more efficiently by removing debris from sensitive mechanical components, as well as ensuring unrestricted airflow. Clean efficient systems are less likely to have mechanical failure, have a longer life span, and operate more effective than dirty systems.
