What is quality?

What makes a quality installation?

ACCA worked with dozens of contractors and industry leaders to quantify quality. This nationally approved specification, ANSI/ACCA 5 Q1-2007: HVAC Quality Installation Specification, Residential and Commercial Heating, Ventilating and Air Conditioning (HVAC) Applications, meets the needs of:

• Contractors – to differentiate their ability to install residential and commercial HVAC systems which satisfy the occupant and increase energy savings.
• Home Owners – identifies tasks and practices that lead to healthy homes, long equipment life, and reduce utility bills.
• Building Owners separate line?
• HVAC trainers – to assist in the ongoing development of appropriate course curricula and training programs.
• Utilities – to integrate the recommendations into their incentive programs.
• Equipment manufacturers – to highlight and encourage quality installation practices, resulting in better equipment performance and durability

• Design Aspects (i.e., building heat gain/loss load calculations, proper equipment capacity selection, matched systems).
• Equipment Installation Aspect (i.e., airflow, refrigerant charge, electrical requirements, on-rate gas-fired equipment, combustion venting system, and system controls).
• Duct Distribution Aspect (i.e., duct leakage and airflow balance).
• System Documentation and Owner Education Aspects.

• Building heat gain/loss load calculations
• Proper equipment capacity selection
• Matched Systems (splits only)

• Airflow across the indoor coil
• Refrigerant charge
• Electrical requirements
• On-rate for gas-fired equipment
• Combustion venting system
• System controls

• Duct leakage
• Airflow balance

• Proper system documentation to the owner
• Owner/operator education
