Florida Cooling Cost Math

SEER2 Energy Savings Calculator

How much can I save by upgrading my AC SEER2 rating?

SEER2 savings depend on the old efficiency, new efficiency, system size, cooling hours, and your electric rate. In Broward County, the rate should usually start with FPL or the cents-per-kWh on your bill, then be edited for your actual utility and plan.

Calculator Inputs

Annual kWh = tons x 12,000 BTU divided by SEER2 divided by 1,000 x cooling hours. Savings = old kWh minus new kWh x electric rate.

Turn SEER2 ratings into Florida dollar math

SEER2 is easiest to understand when it is translated into kWh and dollars. The calculator uses system tonnage, old efficiency, new efficiency, cooling hours, and an editable electric rate so the result is tied to the homeowner's bill instead of a national average.

Broward County homeowners should treat the default rate as a planning starting point. The strongest input is the cents per kWh from the current bill, because utility charges and plan details can change over time.

  • Higher SEER2 lowers estimated cooling kWh for the same tonnage and runtime.
  • Use the electric rate from the current bill whenever possible.
  • Savings should be compared with repair risk, comfort, and replacement cost.

When efficiency savings matter most

SEER2 upgrades tend to matter most when the old system is inefficient, oversized, running long hours, or already being replaced for reliability reasons. Efficiency alone may not pay for a project, but it can change the best equipment option when replacement is already on the table.

If the home has duct leakage, weak airflow, low insulation, or a thermostat schedule that forces long recovery cycles, those issues can affect the real savings. Use the number as a planning answer, then confirm the house conditions that influence runtime.

  • Longer cooling runtime makes efficiency gains more visible.
  • Duct and airflow problems can reduce real-world savings.
  • Compare multiple SEER2 options before choosing equipment.

What makes a SEER2 answer useful for Florida homeowners?

A useful SEER2 answer converts efficiency into estimated kWh and dollars using system size, runtime, cooling hours, and an electric rate the homeowner can edit from the current bill.

Next step: Use the bill rate instead of a national average whenever possible.

Why might the real savings differ from the calculator?

Real savings can change when ducts leak, returns are undersized, insulation is weak, thermostat recovery is long, or the home has humidity and airflow problems that keep runtime high.

Next step: Pair SEER2 math with duct, airflow, and comfort review.

Local answer target

When should SEER2 savings influence replacement?

Savings should influence replacement when the old unit is inefficient, runs long hours, or is already being replaced for age and reliability. Efficiency is one part of the project, not the only reason to buy.

Next step: Compare several equipment options with the same home conditions.

SEER2 Energy Savings Calculator FAQs

Why does the rate field stay editable?

Electric bills include fuel, base, recovery, taxes, and plan-specific charges. The editable field keeps the math useful even when rates change.

Does SEER2 savings pay for a new AC by itself?

Usually it is only one part of the decision. Comfort, reliability, repair risk, humidity, financing, and installation scope also matter.

What if my old unit uses SEER instead of SEER2?

Use the rating you know as a planning input. Abraham AC can help compare actual equipment options during the estimate.
