When the summer comes, so does the high heat. While this can mean a time for adventure and relaxing by the pool, it can also mean a need to run the air conditioning just to stay comfortable. Traditionally, an in-house unit is expensive, requires professional installation, time to install, and a tremendous amount of maintenance.

For this reason, small window air conditioners were introduced. They got the job done, though they were very loud.Also, you had to be near the unit in order to enjoy the full benefits.

Recently we have been reviewing portable air conditioners, and those are a great solution.Often when it comes to a small room air conditioner, the compressor is built into the unit.This means that the loudest part of the air conditioner isin the room with you. And you may want a quieter option.

Mini split units help solve this problem and do a tremendous job of it.With a sleek design and slim profile, these units keep the compressor outside while blowing cool air inside. But not only cool air. Mini splits also allow dual functionality as heaters. As the summer months approach, we would suggest you take a look at a mini split unit as an option.

Product Information

The Pioneer Air Conditioner WYS018GMFI22RL Mini Split Heat Pump has an 18,000 BTU output for both cooling and heating functions. This mini split unit is rated to heat in temperatures as low as -12°F—exactly when you would need heating the most!

Though more complex than a portable unit, this small room air conditioner is ductless, comes with its own hose, and has a full team of customer support ready to answer any installation questions. The compressor sits outside of the swelling, but even then, it runs at only 61 decibels.The inside unit is much quieter and is connected to the outside unit by hoses that are included in the purchase.

For proper temperature control, there is a flat front panel with an LED display that is dimmable, so you don’t have to worry about annoying bright lights during the night.The Pioneer also comes with a remote control that has a large LCD display.You can control the unit without ever having to leave the couch!

The heating element has variable speeds and utilizes an ultra-high efficiency DC inverter compressor. With copper piping, insulation, and overheating protection, you can be comfortable in any climate.

There are multiple fan modes and an advanced night mode that modulates the temperature at night. This saves energy during the night and matches the body’s natural temperature fluctuations for optimal comfort.Combined with air discharge louvers that swing automatically, this small room air conditioner has everything you need to keep your room comfortable all day and night.

Since the outside unit and compressor sit outside, it is very important to read the installation specifications and instructions carefully. You will need to make sure to install the exhaust hoses properly and to make sure you do not ink or block them.Other than that, the directions are straight forward and the installation does not require a professional.

This is a more expensive option than an inside portable unit but has far more functionality and power with far less of the noise and drainage issues than a portable unit.Serious cooling and heating needs require a serious unit and the Pioneer Mini Split is just that.
