1. What is Seasonal Energy Efficiency Ratio?

The Seasonal Energy Efficiency Ratio (SEER) measures the cooling efficiency of air conditioners and heat pumps. It represents the ratio of total cooling output (in BTU) to total energy input (in watt-hours) over a typical cooling season.

2. How Does the Calculator Work?

The calculator uses the SEER formula:

Where:

• Total Cooling Output — Total cooling provided during the season (BTU)
• Total Energy Input — Total electrical energy consumed during the season (Wh)

Explanation: Higher SEER values indicate more efficient cooling systems that provide more cooling per unit of energy consumed.

3. Importance of SEER Calculation

Details: SEER rating is crucial for evaluating energy efficiency of cooling systems, estimating operating costs, and meeting energy efficiency standards. Higher SEER ratings typically mean lower electricity bills and reduced environmental impact.

4. Using the Calculator

Tips: Enter the total cooling output in BTU and total energy input in watt-hours. Both values must be positive numbers. The calculator will compute the SEER ratio in BTU per watt-hour.

5. Frequently Asked Questions (FAQ)

Q1: What is a good SEER rating?
A: Modern air conditioners typically have SEER ratings between 13 and 21. Higher SEER ratings indicate better energy 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 (usually 95°F).

Q3: Are there minimum SEER requirements?
A: Yes, in the United States, the Department of Energy sets minimum SEER requirements that vary by region, with higher standards in southern states.

Q4: Does a higher SEER rating always mean better?
A: While higher SEER means better efficiency, the cost difference may not be justified in milder climates with shorter cooling seasons.

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.
