Higher SEER ratings indicate increased energy efficiency. Let’s consider a scenario where we compare a traditional AC unit with a SEER rating of 13 to an inverter AC with a SEER rating of 20.

To calculate the energy savings and payback period, we need to determine the difference in energy consumption between the two systems. The formula is as follows:

Energy Savings = (Energy consumed by traditional AC – Energy consumed by inverter AC) * Electricity rate

Let’s assume the traditional AC unit consumes 1200 kWh per year, and the inverter AC consumes 800 kWh per year.

If the electricity rate is $0.12 per kWh, we can plug these values into the formula:

Energy Savings = (1200 kWh – 800 kWh) * $0.12/kWh

Energy Savings = 400 kWh/year * $0.12/kWh

Energy Savings = $48/year

Now, to calculate the payback period, we divide the upfront cost difference between the two systems by the annual energy savings. Let’s assume the inverter AC unit costs $1000 more than the traditional AC unit:

Payback Period = Cost difference / Energy Savings

Payback Period = $1000 / $48/year

Payback Period 20.8 years

In this example, it would take approximately 20.8 years for the energy savings of the inverter AC to offset the $1000 upfront cost difference when compared to a traditional AC unit.

Although the payback period may seem lengthy, it’s important to consider the long-term benefits of energy savings and the overall comfort provided by the inverter AC system.
