1. What is SEER?

SEER (Seasonal Energy Efficiency Ratio) is a measure of air conditioning efficiency that represents the cooling output during a typical cooling season divided by the total electric energy input.

2. How Does the Calculator Work?

The calculator uses the SEER formula:

Where:

• \( BTU \) — British Thermal Units (cooling capacity)
• \( W \) — Watts (power consumption)
• \( h \) — Hours (operating time)

Explanation: The formula calculates the efficiency ratio by dividing the total cooling output (BTU) by the total energy input (watt-hours).

3. Importance of SEER Calculation

Details: SEER rating helps consumers compare the energy efficiency of different air conditioning systems. Higher SEER ratings indicate more efficient systems that consume less energy for the same cooling output.

4. Using the Calculator

Tips: Enter BTU (cooling capacity), watts (power consumption), and hours (operating time). All values must be valid positive numbers.

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 is a seasonal efficiency rating that accounts for varying temperatures throughout a season, 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 efficiency standards in southern states.

Q4: Can SEER be used for heating systems?
A: No, SEER is specifically for cooling efficiency. Heating systems use HSPF (Heating Seasonal Performance Factor) to measure efficiency.

Q5: How much can a higher SEER rating save?
A: Upgrading from SEER 10 to SEER 14 can reduce cooling costs by about 30%, while upgrading to SEER 20+ can save up to 50% compared to older units.
