EER (Energy Efficiency Ratio)
EER (Energy Efficiency Ratio) is a standard measurement used in the air conditioning industry to show how efficiently an AC unit works. Think of it like a miles-per-gallon rating but for air conditioners. The higher the EER number, the more energy-efficient the unit is. This term is important for HVAC technicians and contractors because customers often want energy-efficient solutions to save money on their electricity bills. When reviewing resumes, you might see this mentioned alongside other efficiency ratings like SEER (Seasonal Energy Efficiency Ratio) or COP (Coefficient of Performance).

Q: How do you calculate potential energy savings when upgrading from a lower to higher EER unit?
Expected Answer: They should demonstrate knowledge of comparing EER ratings, energy consumption calculations, and ability to estimate cost savings over time while considering factors like local climate and usage patterns.
Mid Level Questions
Q: What factors can affect an AC unit's EER rating in real-world conditions?
Expected Answer: Should discuss maintenance, installation quality, environmental conditions, and proper sizing of units, showing practical field experience with efficiency ratings.
Q: What's the difference between EER and SEER ratings?
Expected Answer: Should explain that EER is measured at a single operating condition while SEER considers seasonal variations, demonstrating understanding of different efficiency measurements.
Junior Level Questions
Q: What does EER stand for and what does it measure?
Expected Answer: Should be able to explain that EER stands for Energy Efficiency Ratio and measures how efficiently an AC unit converts electricity into cooling power.
Q: What is considered a good EER rating?
Expected Answer: Should know that ratings above 12 are considered good, with higher numbers indicating better efficiency, showing basic knowledge of industry standards.
