Definition: This calculator estimates the potential savings from upgrading to a more efficient HVAC system with a higher SEER rating.
Purpose: It helps homeowners and businesses evaluate the financial benefits of upgrading their air conditioning systems.
The calculator uses the formula:
Where:
Explanation: The formula calculates the difference in energy consumption between the old and new SEER ratings, then converts it to dollar savings.
Details: SEER (Seasonal Energy Efficiency Ratio) measures air conditioning efficiency. Higher SEER means better efficiency and lower operating costs.
Tips: Enter your current energy use (kWh), current SEER rating (default 10), new SEER rating (default 16), and electricity rate (default $0.12/kWh).
Q1: What's a typical SEER rating for older units?
A: Units installed before 2006 typically have SEER ratings between 8-10.
Q2: What's the minimum SEER rating today?
A: As of 2023, the minimum is SEER 14 in northern states and SEER 15 in southern states.
Q3: How do I find my current energy use?
A: Check your electricity bills for annual cooling kWh or use your total kWh if cooling is your main electric load.
Q4: Do higher SEER units cost more?
A: Yes, but the energy savings often offset the higher initial cost over time.
Q5: Are there other benefits to higher SEER units?
A: Yes, they often provide better comfort, quieter operation, and may qualify for rebates.
