The NADCA Guide to Proper HVAC System Cleaning

 

This time of year the money mailers and coupons are everywhere, the most important thing you can do is to compare the SERVICE not the price.

 

Cleaning your homes hvac system includes more than just the ducts. To completely clean and treat the entire system this is what should be cleaned:

Vent covers, duct work, furnace fan and fan compartment, air conditioning coil, coil compartment and drain pan, lower heat exchanger compartment.

 

This is everything air will pass through in your homes ventilation system. Some companies claim to “clean” or “air wash” the fan or blower in place……this is not good enough if you want to stop air borne particulate, removal, washing and re assembly is the correct way to ensure proper cleaning.

 

Now that you know the proper items to be cleaned we will cover the proper tools of the trade. There are specialized tools just for duct cleaning contractors these do not include:

Carpet cleaning machines, home center shop vacs, attachments for truck powered carpet cleaning machines, leaf  blowers or suckers etc.

They should include HEPA filtered vacuums, large HEPA filtered vacuums to capture the dirt or a truck powered vacuum, agitation devices powered by compressed air or brushes. The goal is to agitate the dirt and debris and capture it.

 

Complete cleaning also needs to have inspection, the company performing the cleaning should have access openings for inspection and cleaning. If a contractor says “we don’t cut into your duct work” this is most likely the wrong contractor for the job. Access openings are necessary for vacuum attachment, insertion of cleaning tools, and inspection.

 

Remember you want trained specialists working on your expensive furnace and duct system, proper training and knowledge take time to develop and to perfect.

RCS spends a considerable amount of money on training and state of the art tools to  ensure a quality job every time.

RCS is one of only a few companies statewide with a powerful gas powered vacuum truck to perform the cleaning. Equipment makes a difference and we can prove it!

RCS provides ventilation cleaning services to Missouri and southern Illinois customers. NADCA trained and certified technicians ensure that standards are being followed and met.

Has Duct Cleaning Been Recommended To You?

 

Where do you start? How do you hire the best contractor? Duct cleaning is not as simple as most carpet cleaning, window cleaning etc companies would lead you to believe. It takes a true specialist with proper training, education, and equipment.

 

 

 

You first starting place should be NADCA the national air duct cleaners association. They set the standards, provide education and certify companies. This alone will not guarantee a proper cleaning job.

Consult with your neighbors and friends to see who they used, and where they happy with the job performed. Many sites have contractor reviews: angie’s list, service magic, google places, yahoo, BBB etc. Read the comments left by customers.

 

I highly recommend using a contractor that only performs duct cleaning, remember you want a specialist working on your expensive heating and cooling system.

 

Ask the proper questions, who will come to my home? A sub-contractor? Are they capable of cleaning the entire air handling system?

A complete and thorough cleaning to help asthma and allergy suffers should include cleaning of the supply and return air  duct work interior , vent covers, washing of the fan and fan compartment, washing of the air conditioning coil and coil compartment.

By cleaning all of these components you have cleaned everything that air passes through in your HVAC system.

Experience plays a big part in the quality of service, how long have your technicians been cleaning air ducts?

 

 

vacuum truck

Powerful vacuum truck provides the suction for cleaning.

 

 

What type of equipment do they use? “Negative air” (under suction)  cleaning systems are considered industry standard for duct cleaning.

Roto brush, shop vacuums and carpet cleaning equipment will not provide a thorough cleaning job.

 

 

 

 

Last but not least don’t expect a thorough and professional job for $49.99!  Do you think a company can spend an entire day at your home for that? Through takes time, an average duct cleaning for a 1000 square foot home is about $400.

This may not include the furnace cleaning. Time will range from 4 hours to 6 hours or more depending on the access and dirt load.

Clearing the Air: What an HVAC cleaner should really do in your home

Filthy furnace fan, can you imagine not having this cleaned?

 

(ARA) – Those statistics about indoor air pollution and it’s relation to respiratory problems convinced you it was time to get your heating, ventilation and air conditioning system (HVAC) cleaned. You were even looking forward to the increased energy efficiency that a clean system can provide. But $49 and one very noisy service call later, you’re still sneezing and you haven’t seen any dip in your energy bill.

 

 

 

What happened?

“A very low service charge may indicate the service provider isn’t performing a thorough cleaning and maintenance of your home’s entire HVAC system,” says Matt Mongiello, president of NADCA, the HVAC Inspection, Maintenance & Restoration Association. “He or she may have done nothing more than blow air through the ducts and clean off vent grills inside the home. A cleaning performed to NADCA standards – which are cited by the EPA as a best practice – encompasses much more than just the ductwork.”

 

HVAC companies are among the top 10 industries with the most complaints, according to the Better Business Bureau. So how can a homeowner know if a service provider is doing a good job, or just blowing hot air?

The EPA recommends you interview companies to ensure they have experience working on your type of system, that they will take steps to protect your home and everyone in it from contamination, and that they comply with NADCA’s air duct cleaning standards.

NADCA members carry general liability insurance, have at least one person on staff trained and certified as an Air Systems Cleaning Specialist, and clean and restore heating and cooling systems following the association’s standards and guidelines. A job done to NADCA standards should include:

* A thorough inspection of the HVAC system before doing any work, and full disclosure of any problems discovered during the inspection.

* Examination of metal ductwork at several random sites to ensure the interior surfaces are free of visible debris.

* Cleaning of both the supply and return air ductwork.

* Removal, cleaning and resetting of all supply registers, return air grilles and diffusers.

* Cleaning of the supply and return air plenums.

* Inspection and/or installation of access panels.

* Cleaning of the air-stream side of the heat exchanger and cleaning of the secondary heat exchanger.

* Removal, cleaning and reassembly of the blower motor.

* Cleaning and inspection of the blower blades and blower compartment.

* Cleaning of the evaporator coil, drain and pan. If the cooling coil is clean, light should shine through it when you point a flashlight at the coils.

* Inspection and repair of the coil fins if needed.

* Replacement of air filters.

* Washing of the air cleaner.

While some companies may tout “duct-cleaning” for very low prices, be wary of these offers,

Mongiello, advises. “A cleaning typically costs between $450 and $1,000 per heating and cooling system, depending on the services offered, the size of the system, how easily accessible it is, the climate in your region and how dirty it is,” he says.

Many of those variables will influence how long the job takes, too. Before you hire a contractor, contact at least two NADCA member companies to provide you with a time estimate for the job. “You’ll get an idea of how long the job should take,” Mongiello says. “But in general, a service provider who’s in and out of your home in an hour or less may be leaving out some steps that are necessary to do the job right.”

Finally, Mongiello advises, feel free to stick around while the technicians do their job. “As long as the homeowner’s presence isn’t compromising anyone’s safety, there’s no reason a consumer can’t observe how a job is done,” he says.
