1. What is SEER?

SEER (Seasonal Energy Efficiency Ratio) is a measure of air conditioning and heat pump cooling efficiency. It represents the ratio of cooling output (in BTU) to 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 — Total cooling output in British Thermal Units (BTU)
• Total Electricity — Total electrical energy consumption in watt-hours (Wh)

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

3. Importance of SEER Calculation

Details: SEER rating is crucial for evaluating HVAC system efficiency, estimating energy costs, and making informed decisions when purchasing or maintaining cooling systems.

4. Using the Calculator

Tips: Enter total cooling output in BTU and total electricity consumption in watt-hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good SEER rating?
A: Modern systems typically range from 13-25 SEER. Higher SEER ratings indicate better energy efficiency.

Q2: How does SEER differ from EER?
A: SEER represents seasonal efficiency, while EER (Energy Efficiency Ratio) measures efficiency at a specific outdoor temperature.

Q3: Are there minimum SEER requirements?
A: Yes, in many regions there are government-mandated minimum SEER ratings for new HVAC installations.

Q4: Does higher SEER always mean better?
A: While higher SEER indicates better efficiency, the optimal SEER rating depends on climate, usage patterns, and budget considerations.

Q5: How can I improve my system's SEER?
A: Regular maintenance, proper sizing, clean filters, and upgrading to a higher efficiency system can improve SEER performance.
