Air Duct Cleaning Charlotte NC - Is Duct Cleaning
Necessary?
3
Many HVAC repair and maintenance companies also
offer air duct cleaning services, which typically
cost from 300 to 500.
4
There are also companies that only do duct
cleaning, and they generally recommend having air
ducts cleaned every 3 to 5 years, or even more
frequently to reduce pollutants in the air.
5
However, the U.S. EPA (Environmental Protection
Agency) warns that there is no scientific
evidence that cleaning air ducts regularly
improves air quality
6
and some HVAC professionals will tell you it is a
waste of money, although some allergy sufferers
have reported that having their ducts cleaned has
led to reduced allergy symptoms and cleaner air.
7
Although the EPA does not recommend routine duct
cleaning, it does suggest it be done when there
are specific reasons for doing so. This would
include factors such as
8
You see substantial quantities of visible mold
growth within the heating ducts or present on
other parts of your home's HVAC system.
9
Excessive amounts of dust or debris clog the duct
system and release dust or debris into the home
through the vent registers when the system
operates.
10
Pests such as mice, rats or insects have
infested portions of the duct system.
11
According to the NADCA, consider the following
when making a decision whether or not to clean
your home's air ducts
12
The National Air Duct Cleaners Association agrees
with most of the EPA's stance on air duct
cleaning with one exception -- it does recommend
routine cleanings every few years.
13
Smokers in the household
Pets that shed excessive amounts of hair and
dander
Water contamination or damage to the home or HVAC
system
14
Residents with allergies or asthma who might
benefit from a reduction in the amount of indoor
air pollutants in the home's HVAC system
15
After home renovations or remodeling
Prior to occupancy of a new home
16
Avoid duct-cleaning scams
17
When you hire someone to paint or build a stone
patio, it's easy to see whether they've done a
good job.
18
But with services like duct-cleaning, there's
much more risk of fraud because the homeowner
can't easily verify the work.
19
A disreputable company may not have the proper
equipment to do the job correctly, could
overcharge you, or might actually leave the ducts
dirty or filled with debris that could cause
costly damage to your home's HVAC system.
