1. What is the Split System Running Cost?

The Split System Running Cost calculates how much it costs to operate your HVAC split system based on its power consumption, operating time, and your electricity rate. This helps homeowners estimate energy expenses.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Power \) — System power consumption in kilowatts (kW)
• \( Time \) — Operating time in hours
• \( Rate \) — Electricity cost per kilowatt-hour ($/kWh)

Explanation: The formula multiplies the system's power draw by how long it runs and the cost you pay for electricity.

3. Importance of Running Cost Calculation

Details: Understanding your HVAC system's operating costs helps with budgeting, comparing system efficiency, and making informed decisions about usage patterns.

4. Using the Calculator

Tips:

• Find your system's power rating on the nameplate or manual
• Estimate daily or monthly usage hours
• Check your electricity bill for the current rate
• All values must be positive numbers

5. Frequently Asked Questions (FAQ)

Q1: How can I reduce my split system running costs?
A: Regular maintenance, proper insulation, using programmable thermostats, and upgrading to energy-efficient models can reduce costs.

Q2: Is this calculation accurate for all split systems?
A: It provides an estimate. Actual costs may vary based on system efficiency, temperature settings, and environmental factors.

Q3: Where can I find my exact electricity rate?
A: Check your utility bill - rates may include supply charges, delivery charges, and vary by time of use.

Q4: Should I use peak or off-peak rates?
A: For most accurate estimates, use the rate that applies when your system runs most frequently.

Q5: Does this account for startup power surges?
A: No, this calculates steady-state operation. Startup surges may add slightly to actual costs.
