Daikin DX20VC: Ultra High Efficiency System

Are you enjoying the Texas summer heat yet? Once the temperatures began to climb into the typical August triple digits, you may have started hearing about Ultra High Efficiency AC systems (UHE). We are on a mission to educate you about the benefits that these systems provide, so you can stay cool and collected in this hot weather. In a recent post, we briefly compared two UHE systems, the Daikin DX20VC and the Lennox XC25. You can view the post and video here, if you haven’t gotten a chance to see it yet. Today, we will be covering the Daikin DX20VC on a deeper level, and take a detailed look at the core features and benefits of the system.


The Daikin DX20VC is one of the most advanced air conditioning units on the market today. Equipped with Daikin’s top technologies, the DX20VC is energy-efficient and intelligently designed to keep you comfortable all day long. Quiet operation, reliability, and consistent comfort levels, are just a few of the many benefits you will receive from the DX20VC. Let’s discuss these features more in depth, so you can find out how the DX20VC can help you stay cool.

Daikin Inside Variable-Speed Compressor

The Daikin Inside variable-speed compressor is extremely energy efficient, and boasts a 24.5 SEER rating. The variable-speed compressor helps you save energy by allowing the system to use only the minimum amount of energy required to keep the temperature consistent. How does the variable-speed compressor compare to single speed compressors? To make this concept easier to understand, we will compare the compressor to the engine in a car.

If your car only had one available speed, and your options were to be completely still or going 60mph, your car would be very inefficient. Your fuel economy would suffer, and there's no way that you or your passengers would be comfortable. This is how a single-speed compressor works. The system will kick on, cool your room and then shut off completely. This process will repeat throughout the day to keep your home cool. This inefficiency results in higher energy expenses and inconsistent comfort levels. 

A variable-speed compressor is comparable to a car that's cruising at a comfortable speed, with no abrupt stops and starts, providing a smooth and comfortable ride. Instead of shutting off and then on to cool your home, a variable-speed compressor will stay on, only using the necessary amount of power to keep your home's temperature consistently cool.

Noise Levels

Although the DX20VC is a powerful system, it manages to operate with very low noise levels. The unit comes with a sound blanket that is designed specifically for reducing noise levels. Coupled with the high-efficiency ECM condenser fan motor, these sound reduction features keep the noise level of the DX20VC to around 58dba. That’s nearly the equivalent to hearing your dishwasher in the next room!

The DX20VC is also compatible with the ComfortNet™ Communicating System, which provides continuous monitoring of the system’s performance, and also has the ability to remotely control the AC unit.
