New Ruud 18 SEER System Cuts a DeLand Home's Energy Bill by 23% in One Month
We let the actual energy data do the talking. Here is what happened after we installed a Ruud 18 SEER2 high-efficiency system in March 2026.
We talk a lot about SEER ratings and energy efficiency. But nothing makes the case better than real numbers from a real home. This is that story.
The Situation: A DeLand Home With a Struggling Old System
In early 2026, a homeowner in DeLand reached out to us. Energy bills had been climbing for years. February 2026 was the final straw - the old system pulled nearly 3,400 kWh that month, working overtime just to keep up. After a full assessment, we recommended a Ruud 18 SEER2 high-efficiency system .
Ruud is one of the most reliable names in the HVAC industry - built tough, backed by strong warranties, and engineered for Florida's demanding year-round cooling climate.

What is SEER2? SEER2 is the updated federal efficiency standard introduced in 2023. It measures how much cooling your system delivers per unit of electricity consumed. An 18 SEER2 system is roughly 40% more efficient than the 10-13 SEER systems common in older Florida homes.
The Installation: March 2026
Our crew completed the full installation in March 2026 - right before Florida's heat season. New air handler, new outdoor condenser, new refrigerant lines, a proper load calculation, and a full commissioning to verify peak efficiency. Then we waited for the data.
The Results: The Numbers Speak for Themselves
Based on actual Duke Energy billing data from a DeLand, FL home. Customer identity withheld.
The chart shows the full picture. Usage climbed through summer 2025 as the old system struggled, spiked to nearly 3,400 kWh in February 2026, then dropped sharply the moment the new Ruud came online. April 2026 - the first full month on the new system - came in at 909 kWh , down from 1,177 kWh the prior April. A 268 kWh reduction, 23% less electricity , for the exact same home.
Why the Ruud 18 SEER2 Performs So Well in Florida
- Two-stage compressor - runs at lower capacity most of the time, ramping up only when demand requires. This is where most of the efficiency gain comes from.
- Variable-speed air handler - moves air more quietly and efficiently than single-speed systems
- Better dehumidification - you feel comfortable at a higher thermostat setting, saving even more
- Copper-fin condenser coils - more durable in Florida's humidity and salt air
- 10-year parts warranty when properly registered after installation
What Could This Mean for Your Home?
- Upgrading from 10 SEER to 18 SEER2: estimated savings of 35-45% on cooling costs
- Upgrading from 13 SEER to 18 SEER2: estimated savings of 25-35% on cooling costs
- Upgrading from 15 SEER to 18 SEER2: estimated savings of 15-20% on cooling costs
- In Florida's year-round climate, that can mean $400-$900 per year back in your pocket

The Bottom Line
A 23% reduction in electricity use in the first full month. A total April bill under $152. A system that will keep this DeLand family comfortable for the next 15 or more years while paying for itself through energy savings.
