SEER Formula:
| From: | To: |
SEER (Seasonal Energy Efficiency Ratio) is a measure of air conditioning and heat pump cooling efficiency. It represents the ratio of cooling output in British Thermal Units (BTU) to energy input in watt-hours over a typical cooling season.
The calculator uses the SEER formula:
Where:
Explanation: The SEER rating indicates how efficiently an air conditioning system converts electrical energy into cooling power over an entire cooling season.
Details: Higher SEER ratings indicate more energy-efficient systems, leading to lower electricity bills and reduced environmental impact. Modern standards require minimum SEER ratings that vary by region.
Tips: Enter total cooling BTU and total watt-hours consumption. Both values must be positive numbers. The result shows the SEER rating in BTU per watt-hour.
Q1: What Is A Good SEER Rating?
A: SEER ratings typically range from 13 to 25+. A rating of 14-16 is standard efficiency, 17-21 is high efficiency, and 22+ is ultra-high efficiency.
Q2: How Does SEER Differ From EER?
A: SEER measures seasonal efficiency under varying conditions, while EER (Energy Efficiency Ratio) measures efficiency at a specific outdoor temperature (95°F).
Q3: Why Is SEER Important For Consumers?
A: Higher SEER units cost more initially but save money on energy bills over time. The payback period depends on local climate and electricity rates.
Q4: Are There Minimum SEER Requirements?
A: Yes, minimum SEER requirements are set by the Department of Energy and vary by region, typically ranging from 13 to 15 SEER depending on location.
Q5: How Often Should SEER Be Calculated?
A: SEER is typically calculated during system design and testing. For existing systems, it can be estimated through seasonal energy consumption monitoring.
