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 total cooling output (in BTU) to total energy input (in watt-hours) over a typical cooling season.
The calculator uses the SEER formula:
Where:
Explanation: Higher SEER ratings indicate more efficient systems that provide more cooling per unit of energy consumed.
Details: SEER rating is crucial for evaluating energy efficiency of cooling systems, estimating operating costs, and making informed purchasing decisions. Higher SEER ratings typically mean lower electricity bills and reduced environmental impact.
Tips: Enter total cooling output in BTU and total energy input in watt-hours. Both values must be positive numbers. The calculator will compute the SEER rating in BTU/Wh.
Q1: What is a good SEER rating?
A: Modern systems typically range from 13 to 25 SEER. Higher numbers indicate better efficiency. The current U.S. minimum standard is 14 SEER for most regions.
Q2: How does SEER differ from EER?
A: SEER represents seasonal efficiency under varying conditions, while EER (Energy Efficiency Ratio) measures efficiency at a specific outdoor temperature (95°F).
Q3: Can I calculate SEER for a single day?
A: While technically possible, SEER is designed as a seasonal measurement that accounts for varying temperatures and operating conditions throughout a cooling season.
Q4: Does higher SEER always mean better?
A: Higher SEER systems are more efficient but also more expensive. The optimal choice depends on your climate, usage patterns, and budget.
Q5: How can I improve my system's SEER rating?
A: Regular maintenance, proper sizing, clean filters, and ensuring good ductwork can help maintain optimal efficiency. For significant improvements, consider upgrading to a higher SEER rated system.
