That's because they combine multiple energy-saving technologies to provide better performance with less wasted energy.
A major contributing factor in mini split efficiency is their use of inverter technology.
Inverter technology enables your system to generate only the amount of heating or cooling needed to maintain the desired temperature.
Inverter Technology for Comfort
Unlike traditional systems that just turn on and off, allowing temperature to fluctuate up and down, inverter-driven mini split systems continuously monitor inside temperature and adjust output to keep the temperature consistently where you want it to be.
This means you're consistently comfortable, instead of having moments where you're either too cold or too hot. Inverter-driven mini split systems are smart, so they know how much heating or cooling to put out at any given moment to maintain the desired temperature.
And because they have longer run times at lower speeds, they remove more moisture from the air, keeping your living space even more comfortable by reducing humidity.
Nearly all mini split systems on the market today feature inverter technology, and they've become the new standard in air conditioning efficiency.
Inverter Technology for Efficiency
Smart inverter technology enables your air conditioning system to be more conservative, lowering energy costs by using less electricity to serve the same purpose. In addition to being more conservative in their energy usage, they're also more effective at conditioning your living space.
Hypermiling Imagine you floor the gas peddle in your vehicle until you reach 70 mph, then completely take your foot off the gas until your vehicle slows to 50 mph, then floor the gas peddle again until you reached 70, and so on. That's like a central air system. It just turns on and off to keep indoor temperature in the ballpark of what you selected on your thermostat.
A mini split system is like varying your pressure on the gas pedal to keep traveling at a consistent 60 mph. You use less gas when you drive a constant speed than you do by repeatedly accelerating and slowing down. You limit energy costs by maintaining a stable temperature than you do by a constant cycling of running full blast, then shutting off.
Inverter-driven mini split systems accomplish this through the use of advanced control algorithms, inverter-driven compressors, and intelligent valves. These smart inverter technologies enable mini split systems to reach efficiency levels greater than 30 SEER. When comparing this to traditional central air systems, which generally top out at 18 SEER, you find that an inverter-driven mini split system can save you 30% or more on your electric bill!
