1. What is the SEER Rating?

The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning cooling efficiency. Higher SEER ratings indicate more efficient units that consume less energy to produce the same cooling effect.

2. How the Calculator Works

The calculator uses the formula:

Where:

• \( Capacity \) — Cooling capacity in kilowatts (kW)
• \( Hours \) — Operating hours per time period
• \( Rate \) — Electricity cost per kilowatt-hour ($/kWh)
• \( SEER \) — Seasonal Energy Efficiency Ratio

Explanation: The formula calculates energy consumption adjusted for the unit's efficiency (SEER) to determine operating costs.

3. Understanding Your Results

Details: The result shows the estimated cost to run your air conditioner for the specified period. Actual costs may vary based on temperature settings, maintenance, and environmental factors.

4. Energy Saving Tips

Tips:

• Set thermostat to 78°F (26°C) when home, higher when away
• Use ceiling fans to complement AC
• Seal air leaks in windows and doors
• Clean or replace filters monthly
• Consider upgrading to a higher SEER unit if yours is below 14

5. Frequently Asked Questions (FAQ)

Q1: What's a good SEER rating?
A: Modern units range from 14-25 SEER. 14-16 is standard efficiency, 17-21 is high efficiency, and 22+ is ultra-high efficiency.

Q2: How much can I save with a higher SEER unit?
A: Upgrading from 10 SEER to 16 SEER can reduce cooling costs by about 38%, though savings depend on usage patterns and climate.

Q3: Should I run my AC continuously or cycle it?
A: For most efficient operation, set a comfortable temperature and let the thermostat control cycling. Frequent on/off cycles reduce efficiency.

Q4: Does this calculator work for heat pumps?
A: Yes, for cooling mode. Heating efficiency is measured by HSPF (Heating Seasonal Performance Factor).

Q5: How often should I service my AC unit?
A: Professional maintenance annually, plus regular filter changes and coil cleaning as needed.
