Pressure per square inch Atmospheric pressure, at sea level, is 14.7 psia. When one rises into the atmosphere, the atmospheric pressure decreases by 1 psi for every_________________. Vaporization can be increased by _____________ the pressure on a liquid. Every mechanical refrigeration system has __________ different pressure levels. Pressure on the high pressure side of a mechanical refrigeration unit is called _______________. b. discharge or head pressure c. differential l pressure The exertion of pressure on a substance with a constant temperature increases its volume in proportion to the increase in pressure. HVAC technician certification and licensing exams test knowledge and skills related to specific HVAC processes and applications. Many states require technicians who work on heating, ventilation, cooling and refrigeration equipment to be licensed.

This course will provide the training required for a Certified HERS Rater to verify homes under the ENERGY STAR program. The course includes the exam which must be passed to achieve this certification. Successful completion of this course will earn the student 18 RESNET CEU's.
Most ENERGY STAR training programs use a checklist by checklist, item by item approach. We found that method leaves a lot to be desired when you try to apply it in the real world. The “Thermal Enclosure System Rater Checklist” if completed from top to bottom requires you to traverse the same path up to six (6) times - we counted 538 total steps! The ARN optimized training method instead teaches you what to verify inspection by inspection rather than checklist by checklist.

When you look at a window, you are prepared to verify everything needed for that window at one time. This reduces the number of steps to 138 and this is just for one of four (4) checklists which must be completed for ENERGY STAR. Save the steps for the gym. When you are working, every step impacts your profits. Where you choose to get your training can make a significant difference in the amount of time spent on-site and at your computer. ENERGY STAR Program Requirements This module will provide an overview of the ENERGY STAR Program requirements for all participants, the Builder, the Rater and the HVAC contractor. Included is an overview of ENERGY STAR certification paths, the target HERS Index, the Benchmark Home Size and Size Adjustment Factor, and trade-off limitations.
