Blower Door Test Process
A specially-trained Perdue Heating & Cooling
Comfort and Indoor Air Quality Consultant will visit your home and - using
advanced diagnostic instruments and testing procedures - will identify problems
that affect your indoor living environment. Your Perdue Heating & Cooling consultant
will then provide you with a personalized plan to solve these problems,
permanently.
Initial Consultation
Your checkup starts with
an information interview to learn about your current situation. Your input
provides valuable information, such as whether any rooms feel clammy when the
air conditioner is running, or if any parts of the house need to be dusted more
often than others. We encourage all the adults in your home to participate in
this initial consultation since everyone's perception of comfort and indoor air
quality is unique.
Equipment Inspection
 The
inspection begins with your heating and cooling equipment. Your Perdue Heating & Cooling
consultant will visually inspect your equipment for any signs of
deterioration, improper installation, or insufficient maintenance. He or she
will let you know the average life span of your existing equipment. Your Perdue Heating & Cooling
consultant will also evaluate your system's air filtration and
purification efficiency, to determine if improvements would better clean your
indoor air.
Insulation Inspection
Even the best heating and
cooling system will have trouble keeping you comfortable or will cost more to
run if you don't have enough insulation. Your Perdue Heating & Cooling consultant
will visually inspect insulation levels throughout your home and determine if
they meet currently recommended levels. More importantly, he or she will look
for hidden defects, such as hollow wall cavities, that allow air and heat to
bypass your insulation. Attic ventilation levels will also be checked.
Infiltrometer™ Blower Door
Test
All houses should have some air leakage but most leak too much.
Symptoms of excessive leakage include uneven temperatures throughout the house,
wasted energy, excessive dust, cold drafts, dry air in winter, and clammy air in
summer. On the other hand, some homes are too airtight and may have unhealthy
indoor air.
To measure a home's air-tightness, Department of Energy
scientists at Princeton University invented the blower door instrument. It is
often featured in magazines and on television, including National Geographic,
Better Homes and Gardens, Popular Science, and This Old House.
Using an
Infiltrometer™ (a computerized blower door system), your Perdue Heating & Cooling
consultant will evaluate how leaky or airtight your entire home is,
and where improvements can be made.
Air Leakage Evaluation
Not
all air leaks are created equal. From an air quality standpoint, those around
your windows and doors are good leaks, since they let in fresh outdoor air. Bad
leaks let in dusty, moldy or polluted air from your attic, garage, or crawl
space. Leaky air ducts often bring in dirty air, and cause your heating and
cooling equipment to perform well below peak efficiency. As part of the
Infiltrometer™ blower door test, your Perdue Heating & Cooling consultant will
pinpoint where your home's worst air leaks are, and where improvements can be
made.
Air Flow Diagnosis
 If your
air duct system has hidden design flaws or blockages, your air flow will be
restricted or unevenly distributed. This wastes your money and can make your
home uncomfortable. Studies conducted for electric utilities nationwide show
that more than 66% of heat pumps and air conditioners suffer from air flow
problems. Your Perdue Heating & Cooling consultant will conduct "static
pressure" tests - like a blood pressure check for your ducts - to reveal
any hidden blockages or design problems.
Electronic Air
Flow Capture Hood Test
Do you have rooms that are hard to heat or cool?
There are economical solutions. Your Perdue Heating & Cooling consultant will use an air flow capture
hood to measure precisely how much conditioned air is getting to those rooms
(provided the supply vents are accessible). If air flow is low, the causes will
be determined, and appropriate solutions will be prescribed.
Personalized
Improvement Plan
Once the inspection and testing are complete, your
consultant will explain the results, and give you a prioritized plan of
recommended improvements. Many - such as adding insulation or weather-stripping
- can be performed by homeowners as weekend projects. Other improvements may
require professionals. Perdue Heating & Cooling has licensed, bonded and insured
professionals that can handle any of this work for you. This way you have one
company to hold responsible for all the work and any warranties that are
available on that work. |
