Kelvinator JS4BE-018KA Split System Air Conditioner Review

As far as split systems are concerned, the Kelvinator JS4BE-018KA ticks all the boxes with regard to cooling capacity, efficiency, convenience, and design. Simply put, this device is ideal for getting the job done. As always, we advise our readers to follow set precautionary measures before investing in a unit of this type, such as measuring your living space in order to ascertain what size of air conditioner is required, and hiring an experienced specialist for installation.


Cooling Performance

This unit is capable of providing up to 18,000 BTUs of cooling power, making it suitable for large living spaces within a range of approximately 1,000 square feet. It is absolutely imperative that you select a unit that provides the optimum amount of BTUs if you want to maximise the efficiency and operational capacities of your air conditioner. There are numerous guides available online that will lay out how many BTUs your  home requires, however you can also hire a specialist to assess your home prior to purchase.


Efficiency / Certifications

The Seasonal Energy Efficiency Ratio is generally the measure by which we gauge how efficient a unit will perform while in operation. In principle, the higher the figure, the better, as the higher the figure the more efficient the unit, and the more efficient the unit, the more money you save on bills. However, oddly enough, the figure being relatively low is  often not a significant issue, as in certain climates, obtaining a unit with a high SEER rating is simply not necessary. Additionally, units with a very high SEER rating are often more expensive than those with a lower rating, so the buyer must ask themselves; are they are really saving any money by opting for a more expensive, ‘efficient’ unit?

In addition, since 2015, a set of regional SEER minimums have been set in place in the United States, therefore some units are simply not suitable for your area, as they may dip slightly below the minimum requirement. However, with the Kelvinator JS4BE-018KA scoring a SEER of 14 (the highest minimum regional requirement), you needn’t worry.

Moving onto certifications, this unit comes ETL certified, which is a significantly positive aspect of the Kelvinator JS4BE-018KA. This guarantees that this product adheres to federal rules and regulations regarding this type of product. Meanwhile, this product also benefits from an AHRI certification, which testifies that the SEER ratings listed are indeed accurate, which is always a nice reassurance with any air conditioning unit.



Unfortunately, the Kelvinator JS4BE-018KA lacks most, if not all of the convenient design aspects we would usually look for in a home air conditioning unit. These include features such as the wireless remote control, programmable timer, and a range of operational modes such as sleep mode, fan only mode, etc.



Kelvinator employed some innovative thinking in the design of this product, including equipping the condenser with micro-channel coils which are made of aluminium. This results in the hardware being highly resistant to corrosion. In addition, a metal wrapper will shield the condenser coil from outdoor hazards and weather conditions. The unit produces 74dBs of noise pollution, however this is emitted from the outdoor component of the unit, so operation of the Kelvinator JS4BE-018KA will not disrupt home life while indoors.

We strongly advise hiring a specialist to assess your home before investing in a permanent air conditioning fixture. This will ensure that you make the right decision based on the size of your home, the local climate, and any other variable conditions that might affect your air conditioners performance. Additionally, as the Kelvinator JS4BE-018KA weighs a formidable 223lbs (shipping), we insist that, should you choose this unit, you hire an experienced contractor for installation. This is to ensure that proper installation is carried out without damaging your home, or violating federal regulations. As surprising as it may be, botched home air conditioner installations are common, far too common, and quite expensive to remedy.

To conclude our Kelvinator JS4BE-018KA buyers guide, this device is perfectly suitable for implementation in a family residential setting.
