FORWARD
[The Forward is not part of the standard. It is merely informative and does not
contain requirements necessary for conformance to the standard]
Verification activities associated with the ANSI/ACCA 5 QI – 2007 (HVAC Quality Installation
Specification), the QI Standard, involve validating that an HVAC installation adheres to the standard’s
requirements. Verification participants (Contractors, Verifiers, and Administrators) that follow this
document’s protocols will meet the minimum requirements for ensuring that outcome.
Verification participants will benefit from a complete understanding of the requirements in the QI
Standard. All are encouraged to address ancillary operational and business issues such as, but not limited
to:
Entry and training requirements
Installation requirements to the ACCA/ANSI QI Standard
Documentation processing, retention, and information confidentiality
Sampling and verification requirements that ensure credibility
Conflict resolution process
Customer service policies/procedures
Quality control/quality assurance plan
Applicable licensing and/or certifications
A strong, objective HVAC Quality Installation verification effort follows consistent, transparent, and
standardized procedures. The ACCA QI Verification Protocols are for those who intend to protect the
value and integrity of the QI Standard through qualified and objective examination of submitted HVAC
system installations.
It is recognized that a verification effort which conducts a thorough inspection of every HVAC system
installation for compliance to the QI Standard provides the greatest confidence. However, this level of
verification effort requires substantial resources and coordination activities; proving costly and
cumbersome. The intent of these protocols is to provide an approach to effectively evaluate HVAC
system installations while optimizing resources in terms of manpower and expenses.
NOTE: Verification participants using the QI Standard should be aware of the following:
No one may construe, claim or imply that their participation in ACCA/ANSI QI Verification constitutes
ACCA’s approval, acceptance, or endorsement. ACCA currently offers no endorsement of such parties or
services.
Everyone shall understand that the activities they undertake in connection with the ACCA/ANSI Quality
Installation Standard are voluntary.
ACCA reserves the right to actively pursue resolution of noncompliance related to the use of the ACCA
and ACCA/ANSI Quality Installation marks.

INTRODUCTION
INTRODUCTION
[The Introduction is not part of the standard. It is merely informative and does not
contain requirements necessary for conformance to the standard]
This document details the requirements, roles, and obligations for the participants in an organized effort
which ensures that HVAC installations comply with the ANSI/ACCA 5 QI – 2007 (HVAC Quality
Installation Specification) QI Standard. Those HVAC systems which comply with the QI Standard
provide several benefits to building owners including: increased comfort, improved indoor air quality and
proper equipment operation.
Part I of the QI Verification Protocols addresses the purpose, scope, definitions, and an overview of the
verification process for an HVAC system according to sampling and evaluation protocols. These steps
involve the review of an HVAC system installation file and an in-field verification of measurements taken
during the installation. A Verifier evaluates the installation file containing the system design elements,
documentation pertinent to the installation, and customer education elements. The Verifier also
coordinates the in-field verification, measures the different aspects of the HVAC system installation,
records the findings, and verifies that the installation meets the requirements in the QI Standard.
Part II of the QI Verification Protocols provides the general requirements for the primary participants.
The Contractor installs the HVAC system, the Verifier evaluates the HVAC system for conformity to the
QI Standard, and the Administrator provides oversight to the verification effort.
The appendices provide samples and recommendations for a verification effort. Appendix A offers
sample illustrations of forms, reports and other documentation. Appendix B outlines possible fee
considerations and Appendix C offers sample documentation which demonstrates a Verifier’s skill sets.

SAMPLING PROTOCOLS
SAMPLING PROTOCOLS
Recognizing that verifying every HVAC system would be resource intensive; these sampling
protocols provide the minimum requirements for installation file reviews and in-field
verifications.
4.1 Sampling Participation: The Administrator shall have the discretion to employ these
sampling protocols.
4.2 Sampling Criteria: HVAC systems shall be selected for installation file review or in-field
verification in an independent manner which:
4.2.1 Seeks a representative sample of the submitted HVAC systems.
4.2.2 Considers input from the Verifier’s review of the installation file or in-field
verification.
4.3 Sampling Strategy: Contractors may be advanced or demoted from level to level based on
the results of their cumulative performance.
4.3.1 Level 1 Verification:
4.3.1.1 100% of installation files shall be reviewed for compliance to the QI
Standard.
4.3.1.2 Each submitted installation shall receive in-field verification.

Advancing Proficiency Level: The Administrator shall have the discretion to advance the
Contractor to subsequent sampling level (if the administrator supports such levels):
4.4.1 From Level 1 to Level 2: After a minimum of three consecutive installations
have been verified to meet the QI Standard.
4.4.2 From Level 2 to Level 3: The Administrator shall set the policy for advancing to
this level.
Decreasing Proficiency Level: Contractors shall be reduced to the next lower sampling
level using the following protocols.
4.5.1 Installation file reviews: If the Contractor fails three consecutive installation file
reviews.
4.5.1.1 An installation file withdrawn from inspection because it does not meet
the QI Standard shall count against the consecutive review file count.
4.5.1.2 An installation file that has deficiencies, and is corrected shall not
count against the consecutive review file count.
4.5.2 In-field verification: If the Contractor fails an in-field verification, then two
additional verifications shall be coordinated (see 4.6). If either of those two infield verifications fails, then the Contractor shall return to the next lower level.
Subsequent testing of HVAC systems:
4.6.1 Testing for an anomaly: If an HVAC system fails an in-field verification, then
another HVAC system shall be selected to determine if the failed verification was
an anomaly. If either of the subsequent HVAC systems fails the in-field
verification then the other HVAC systems associated with that sampling group of
installations (e.g., the other 27 of 30 HVAC systems) shall be deemed to have
failed as well.
4.6.2 Associated failures in a sampling group: HVAC systems associated with a failed
sampling group, and those which have no in-field verification, must pass the infield verification to achieve QI status.
4.6.3 Evaluation expenses: An Administrator is not obligated to authorize, or bear the
cost of evaluation for associated HVAC systems. Re-evaluation fees may also
be assessed for failed installation file or in-field verifications (see Appendix B).
Expert Systems
The Administrator shall have the discretion to use other sampling strategies which include
expert systems, given that the expert system can adequately evaluate the relationship of
multiple data points, to ensure the applicable installation elements of the QI Standard are
met.
4.7.1 Use of expert systems: The Administrator shall have the discretion to use expert
systems to supplement in-field verifications but shall not reduce the minimum
required in-field verifications.
4.7.2 Requirements for expert systems: Expert systems shall evaluate the relationship
between the following applicable factors and correlate compliance to the QI
Standard:
4.7.2.1 Operating conditions inside and outside,
4.7.2.2 Equipment capacity at those conditions,
4.7.2.3 Refrigerant charge,
4.7.2.4 On-rate tests,
4.7.2.5 Airflow across the heat exchanger,
4.7.2.6 Supply and return air volume (from Test and Balance report), and
4.7.2.7 Duct leakage.

EVALUATION PROTOCOLS
EVALUATION PROTOCOLS
HVAC systems shall be evaluated on two criteria: installation file review and in-field
verification. An HVAC system that passes both portions of the verification review shall be
in compliance with the QI Standard. One criterion shall not prevent the evaluation of the
other. After the evaluation, the Verifier shall notify the Administrator of the verification’s
final disposition.
5.1
Installation file review:
A complete installation file must be submitted by the Contractor to the Verifier for each
HVAC system installation to meet the QI Standard.
The Verifier shall review the
installation file to ensure it conforms to the QI Standard and shall notify the Contractor if
the installation file passes or fails its review. The Contractor shall provide the necessary
documentation to correct the non-conformities or withdraw the installation for verification.
5.1.1
Installation file requirement: The installation file must pass the Verifier’s review
in order to meet the requirements of these protocols.
5.1.2
Installation file completeness: The Verifier shall review the documentation
within the HVAC system installation file and ensure that the pertinent
information is present.
5.1.3
Installation file accuracy: The Verifier shall review the installation file to ensure
the correctness of the following items: load calculation, correct equipment
selection, and system matching.
5.1.3.1
Load calculation (Reference §3.1 of the QI Standard): The Verifier shall
review the load calculation and determine if it is a reasonable
approximation of the building’s load. The Verifier will document the
following information (see the Load Calculation section of Table 2:
Required Information Reported by the Verifier):
a. Design temperatures: In accordance with the load calculation’s
design weather data, or other approved design weather data by the
authority having jurisdiction.
b. Occupants: For residential load calculations, the number of
occupants equals the number of bedrooms plus one3. For
commercial load calculations, refer to the occupancy schedule.
c. Infiltration: Verify use of blower door or other test data. Verify the
load calculation procedure was followed to estimate the infiltration
if infiltration is unknown.
d. Ventilation: Rate is in accordance with codes, standards, and load
calculation procedure or equivalent. Adjust the load calculation for
heat or enthalpy recovery or ventilating dehumidifier.
e. Building orientation: Building component’s exposure on plans or
drawings matches those used in the procedure.
f.
Altitude: Value used is within 500 feet of the altitude for the city
selected for weather data or actual survey data.
g. Latitude: Value used is the same as the city selected for weather
data or actual survey data.
3
Abnormal occupancy requirements (e.g., those differing from 5.1.3.1.b.) will be documented and justified in the
installation file.
HVAC Quality Installation Verification Protocols
EVALUATION PROTOCOLS

h. Duct loads: Ensure load calculation procedure includes the system
loads associated with the duct distribution system.
i.
Total heating load: Sum the different heating component loads and
ensure that the value equals the design load calculation.
j.
Total cooling load: Sum the different sensible, latent, and total
cooling component loads and ensure that the value equals the
design load calculation.
k. Building components: The Verifier shall, as a minimum, randomly
select one (1) room or three (3) to five (5) building components
from the load calculation worksheet (e.g., one window, one door,
one wall or partition, one floor, and one ceiling) for verification.
The Verifier shall calculate, record, and compare their results with
the Contractor’s results. For example:
5.1.3.2
Select one window, and evaluate the correctness of selecting
that component for the procedure observed,
Ensure the correct heating and cooling factors were selected,
Ensure the area (size) of the building component is correct,
If applicable, as with a window, ensure the orientation,
overhang, and internal shading are correct, and
Validate the mathematical calculation’s correctness for the
component’s load.
Excessive deviations in the random selections shall be the
basis to inspect more load components until the Verifier can
determine if the load estimate does or does not approximate
the expected building load. An inaccurate load estimate (see
Table 4: Examples of Deficiencies and Nonconformities) shall
negate the load calculation and fail the HVAC installation.
Equipment Capacity Selection (Reference §3.2 of the QI Standard): The
Verifier shall review the equipment selection reference(s) and
document the necessary information (see the Equipment Selection
section of Table 2: Required Information Reported by the Verifier).
a. Verify that the manufacturer’s performance data meets the load
calculation and design conditions in accordance with ACCA
Manual S, Manual CS or other approved procedure by the authority
having jurisdiction.
b. Verify that the equipment is sized within the tolerance specified in
the QI Standard.
5.1.3.3
System Matching (Reference §3.3 of the QI Standard): The Verifier shall
ensure the equipment has an AHRI or CEE directory certificate or is
matched in accordance with OEM performance data. The Verifier shall
document the necessary information (see the Matched Systems section
of Table 2: Required Information Reported by the Verifier).
5.1.3.4
System documentation to owner: (Reference §6.1 of the QI Standard) The
Verifier shall review the installation file for information pertinent to the

APPENDIX C – SAMPLE DOCUMENTATION THAT DEMONSTRATE VERIFIER COMPETENCY
APPENDIX C │ SAMPLE DOCUMENTATION THAT DEMONSTRATE VERIFIER COMPETENCY
[This Appendix is not part of the standard. It is merely informative and does not
contain requirements necessary for conformance to the standard]
The credibility of a verification effort depends on the Verifiers ability to confidently and professionally
interact with Contractors and building owners. Figures C1 and C2 offer examples of certificates which
demonstrate knowledge in the skills needed to verify HVAC system installations. Administrators may
accept these examples as an indication of a Verifier’s proficiency in each of the following aspects of the
QI Standard. These forms of acceptable documentation are not required; this list is neither exhaustive nor
comprehensive.
The accreditation of any education program providing documentation should be evaluated to ensure it is
valid, reliable, and defensible. Documentation is preferred from organizations or education programs that
meet or are in the process of meeting ISO 17024. ISO 1724 demonstrates an approved level of
accreditation.
