Air Duct Cleaning

Q: How long does a duct cleaning job take?

A: Normally 3-4 hours.  We schedule all jobs at 8:30am and 12:00 noon to 4:00pm Monday-Saturday.
Q: Why do people need to clean thier air ducts?

A: Building debris such as sheetrock dust, saw dust and insulation are found in newer homes while hair, skin flakes, mold, mildew and bacteria are found in older systems.


 

Air Purifiers: CAP600

Q: How do I know when I need to change CAP filters and lamps?

A: To keep the system running at peak efficiency, the furnace blower and the CAP unit must be run in the continuous mode.  Prefilters should be chaged when the amber "change filter" lamp illuminates; UV and UV Plus lamps should be changed yearly; HEPA filters about every two to three years.
Q: Won't portable HEPA units provide the same air cleaning benefits?

A: No.  Studies have shown that air cleaners attached to the main ventilation system are generally much more effective tahn free-standing air cleaners.  Portable units can also be noisy and take up space, and purchasing units for every room would be costly.
Q: Are "HEPA type" filters the same as true HEPA filters?

A: No.  By definition, "true HEPA" filters can allow no more than 3 out of 10,000 0.3-micron particles to pass through.  "HEPA type" filters may allow leakage of as many as 4,500 of 10,000 0.3-micron particles.
Q: Why do the CAP600 and CAP1200 units have blowers?

A: The more efficient a filter is, the higher its resistance to airflow and the greater the loss of HVAC efficiency and performance.  The powerful blower ensures that peak HVAC system performance is maintained.  
Q: I've heard and seen advertisements for allergy filters for under $100.  Why would I buy a CAP HEPA system?

A: You get "what you pay for."  These ads are generally for 1" thick "passive" filters with an electrostatic charged media.  When clean, this type of filter typically catches less than 20% of 0.3-micron particles.  When dirty, almost all particles can pass right through.  HEPA filtes start at 99.97% and actually get more efficient as filters get dirty.
Q: Are the benefits of HEPA filtration recognized by the scientific and healthcare communities?

A:

Numerous CAP units have been purchased as a direct result of physician recommendations.  According to the 1997 ALA publication, "Blueprint for Health," 'Because of its high efficiency at filtering out tiny particulates, HEPA filtration is highly recommended for those individuals who suffer from allergies, asthma, or other respiratory problems.'



 

Filters

Q:

How long do the Clean Air allergy filters last?



A:

The filters should be replaced every 3-4 months.  >>Best way to tell:  There is a yellow side and a white side.  Dirt will almost immediately show on the white side but it does not need to be changed until a haze of dirt is visible on the yellow side.  Filters contine to work at optimal effeciency until this point.
