1. What is the 13 SEER vs 15 SEER Savings Calculator?

The 13 SEER vs 15 SEER Savings Calculator estimates the potential cost savings when comparing air conditioning units with different Seasonal Energy Efficiency Ratio (SEER) ratings. It helps determine the financial benefits of choosing a higher efficiency unit.

2. How Does the Calculator Work?

The calculator uses the savings formula:

Where:

• \( BTU \) — Cooling capacity in British Thermal Units
• \( h \) — Operating hours
• \( C \) — Cost per kilowatt-hour ($/kWh)

Explanation: The formula calculates the energy savings difference between 13 SEER and 15 SEER units, then converts it to dollar savings based on electricity cost.

3. Importance of SEER Comparison

Details: Comparing SEER ratings helps consumers make informed decisions about HVAC system purchases by quantifying potential energy cost savings with higher efficiency units.

4. Using the Calculator

Tips: Enter the BTU capacity of your unit, estimated annual operating hours, and your local electricity cost per kWh. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does SEER stand for?
A: SEER stands for Seasonal Energy Efficiency Ratio, which measures air conditioning and heat pump cooling efficiency.

Q2: How significant are the savings between 13 and 15 SEER?
A: A 15 SEER unit is approximately 15% more efficient than a 13 SEER unit, which can translate to significant savings over the system's lifetime.

Q3: Are there other factors to consider besides SEER rating?
A: Yes, installation quality, proper sizing, maintenance, and local climate all affect overall efficiency and savings.

Q4: What's the typical payback period for upgrading to higher SEER?
A: Payback periods vary but typically range from 2-7 years depending on usage patterns, local energy costs, and climate.

Q5: Are there rebates or incentives for higher SEER units?
A: Many utility companies and government programs offer rebates for installing high-efficiency HVAC systems, which can improve ROI.
