Friedrich – CP18G30B

Friedrich’s CP18G30B is part of a series of the premium window/wall air conditioners that are meant to cater to customers with extra-large rooms.

While wall air conditioners look and offer the same things as their window counterparts there are are few key differences that we shall expound later.

This is a best-in-class model meant to offer not only power but also noise-free experience.

Let’s dive straight to its features and see what this cool-looking premium air conditioner is designed to offer.

Description of the CP18G30B by Friedrich

First, we shall look at its capacity. Freidrich CP18G30B is designed to produce about 19000BTUs of cooling power. This enough power to cool multiple rooms of up to 1000 sq. ft. If you want to cool two rooms that are adjacent to each other, like a kitchen that is connected to a living room, be sure to measure the spaces separately and add the square footage together.

One rule of thumb that you should always remember when calculating your rooms’ requirement is that every square footage would require about 25BTUs of cooling power. This, of course, depends on how well your indoor space is insulated.

In terms of its efficiency, this window/wall air conditioner does fairly well to ensure all-electric energy is converted into cooling power. it is, therefore, an Energy Star rated unit with an EER of 11.2 which is well above the minimum requirements of 10.0 EERs.

However, there is still a very big room for improvement as there are competing models in the market with efficiency ratios as high as 12EER. Nonetheless, according to Energy Guide, it is still able to bring down yearly costs to about $144 through your costs may vary depending on your utility rates and use.

This unit is able to cut operation noise to a minimum which is a good thing especially if you are looking to place it in a room where you are going to spend most of your time like a bedroom or your home office. A noise level of 52dB is pretty low considering this is a heavy-weight machine that needs to move a lot of air.

The filter is antimicrobial and washable to ease the maintenance. You just have to slide it out and vacuum clean it or scrub the mesh and it should be good for use. You should ensure though that it is completely dry before putting it back in the machine.

If you don’t feel like sacrificing a window in order to install an air conditioner, this unit is built to be used in both windows and wall openings. There are no drafts to creep in since the design allows the unit to slide in a sleeve inside your wall which helps secure them safely.

This is important especially to those who are worried about kick-in intrusion by burglars. This is unlike many window air conditioners that can easily be pushed inside and dislodged from the window.

Airflow is 4-way to allow even and faster cool air distribution. There is also an additional Auto Air Sweep swing louvers that oscillate to enable the air to be distributed even further in the room which is important especially in large spaces.

Freidrich CP18G30B also doubles as a heater which makes it useful even in the winter. It will surely save you some money that you could have otherwise used to buy two separate appliances.

Users' feedback

Users quotes on Amazon.comI bought this unit over a year ago and, during this heat wave, I have been so thankful for it that I thought I should give a review. We have a 1600 square foot ranch house. The A/C is in a window at one end, in the living room. It keeps the living room and kitchen perfectly cool even after multiple 90+ days. But what's really impressive to me is that our bedroom at the other end of the house, while warmer than the nearer rooms, is not too warm to sleep. I had no expectations that a window unit could affect the bedroom's temp, but it does a really nice job. And, as A/C units go, this one isn't annoyingly loud. I'm very happy with the purchase."

Users quotes on Amazon.comI own 3 of this model- It is relatively quiet. One lasted 4 years & died unexpectedly. The compressor would not come on. I guess 4 years in this day & age is a good thing. The other 2 are 1 & 2 years old so fingers crossed."
