System Performance
HVAC equipment is only as good as the installation. Studies show that the majority of residential HVACR equipment is not installed to manufacturer specifications,
costing the consumer and the installation company money.
The System Performance Certification is designed to validate one has the knowledge required to properly set up an air conditioning or heating system to achieve the
equipment's desired efficiency ratings.
System Performance Certification is a four-part exam, covering:
- Refrigerant charging
- Psychrometrics
- Combustion efficiency
- Airflow

Residential Heat Load Analyst
Residential energy studies show that 72% of systems are improperly sized.
Determining the proper heating and cooling load for a structure is one of the most important processes before installing a new HVAC system.
A system that is too large or small can greatly impact not only the building occupant’s comfort and health but also the energy consumption of the structure and equipment life.
The Residential Heat Load Analyst Certification is a 100-question exam that measures one's ability to properly understand and determine what is required to perform
a heating and cooling load for a structure. This ensures optimal system performance, less energy consumption, longer equipment life, and greater customer satisfaction.
