Frequently Asked Questions

Q:             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.

Q:             How should a residential HVAC system be cleaned?

All residential HVAC systems should be cleaned following NADCA (National Air Duct Cleaning Association) standards.  The entire system should be placed under negative pressure, through a commercial-grade vacuum with a collection device for safe containment of contaminants prior to disposal.  Any vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.  Technicians systematically go to every vent and trunk line using various tools to agitate, loosen and push debris from within the ductwork to the collection device (For example: brushes, air whips and “skipper balls.”) A professional cleaning job should include the cleaning of the furnace, furnace blower and evaporator coils.

Q:             Is sanitizer necessary to duct cleaning? Do I need it?

There are many air duct cleaning companies in the Kansas City area that offer this very service. Many times they are additional charges that can run into the 100’s of dollars. According to a study conducted by the EPA, sanitizer is not necessary to the cleaning of heating, ventilation and air conditioning systems. Mold, mildew and other bacterial growths can only function in the presence of organic material, not sheet metal. The only organic material present within a normal residential duct system is the dirt and debris, so if an air duct cleaner claims to remove all dust and debris from your system, such a service would be rendered unnecessary.

The EPA also mentions that though sanitizers advertised by many duct cleaners are EPA certified, they have not been tested for HVAC systems and thus do not recommend their application in the service.

Q:             What exactly does a professional HVAC cleaning job include?

A professional HVAC or air duct cleaning job includes the furnace , furnace blower, evaporator cils, supply and return ductwork and registers. Cleaning only part of the system is not effective. A dirty furnace blower, for example, will re-contaminate the air duct system after cleaning. Thus, it is very important to make sure the entire system will be cleaned and make sure the price quote provided covers the entire system.  Unfortunately some companies will advertise a very low price and then charge extra for the furnace, various components ductwork, sanitizing and so forth and before you know it the $99 price is $600 or more! So be careful.

Q:             What is the normal price range for the air duct cleaning service?

The EPA 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, system accessibility, climatic region, level of contamination and type of duct material.”  Consumers should 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. Representatives often show up in their own cars as opposed to company vehicles with nothing more than a vacuum unit similar to a shop vac.  These companies may also persuade the consumer into purchasing unneeded services with or without their permission. (If you have knowledge of a practicing “blow-and-go” air duct cleaner, please contact your local Better Business Bureau to report the company.)

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

The amount of time it takes to clean a residential HVAC system can vary depending on the complexity of the system.  A typical 2,500 sq. ft. home with one furnace will require three to five hours to clean.

Q:             What is a dryer vent and how is it cleaned?

Your dryer vent is the vent found behind the dryer, which carries moisture and lint through its length and expels these materials out of the home. Each company will vary in cleaning methods, but be sure that the company you choose utilizes an agitation tool with a long reach and is flexible in design.

Q:             What are the benefits of dryer vent cleaning?

Cleaning increases the life of your dryer.  When airflow is restricted, this causes your dryer to work harder to dry clothes and puts your appliance at greater risk for a breakdown.

Cleaning reduces energy bills.  With restricted air flow your dry will run longer which drives up your utility bills.

Cleaning reduces fire hazards.  Your clothes dryer is more likely to cause a fire than your furnace, stove and chimney combined.  Prolonged drying cycles can overheat the lint trapped in the dryer vent. This built-up lint can ignite within the dryer cabinet causing a fire in your home.
