Buying Guide For The Best Through The Wall Air Conditioner

As you have decided to get a through the wall air conditioner, you need to understand the basic properties of a through the wall AC and calibrate them regarding your needs. As you have already read about different options in our product description above, you must have gained a decent amount of knowledge already.

After reading the buying guide that we are presenting down below, we are sure that you can easily classify various choices and get the most suited option for yourself. Here are the key features that are needed in a through the wall air conditioner:

1. BTU Capacity

As you have read through our picks for the best through the wall air conditioners, you must have read the term BTU on almost every single product. This BTU unit represents the capacity of the air conditioner. This includes both the heating as well as cooling capacity of the air conditioner.

A single BTU unit stands for energy needed to raise the temperature by 1 degree Fahrenheit. This should give you a clearer idea about how much BTUs you require to heat up or cool down an entire room. For a better perception, consider 20 BTU is required to control a single square feet area. However, you should always choose the highest capacity possible for the best results.

2. Noise Level

Air conditioners require a compressor that pushes the refrigerant through the system for heating as well as cooling. As this compressor has moving parts, it is destined to make a certain amount of noise while operating. Now, air conditioners are generally used in bedrooms as well as living rooms, which are not suitable for a large noise as it would create discomfort in the regular use.

To avoid that, you need to choose the quietest option available for the most comfortable experience. Generally, high capacity air conditioners are louder as compared to the low capacity ones as they require a larger compressor to operate.

3. Energy Efficiency Rating

You will find a certain EE rating on every single air conditioner available in the market. This EE rating stands for energy efficiency rating, which displays a relation between the cooling capacity of the conditioner and the energy required to operate the conditioner per hour.

But, you can simply consider this rating as the representation of how much energy you will need in comparison to other options to give a certain amount of cooling. A high EE rating represents a higher cooling effect with comparatively lower energy consumption. But, such systems generally carry a much higher price tag. On the other hand, the air conditioners that have a lower EE rating are cheaper. But they eventually cost a lot more in the long run due to high energy consumption.

4. Input Requirement

The input required for each air conditioner is represented in the volts. The standard outlet available in every household is 115 volts. Therefore, if you get an air conditioner with a similar requirement, you can just plug it in your default socket and start using the system. But, if you decide to go with the higher capacity option, you will have to get a special outlet designed by an electrician that supports the required input. This generally happens with high capacity options that require 220 or even 230 volts input to operate.

5. Reliability

Reliability is possibly the most important aspect of an air conditioner as there are a lot of different parts in an air conditioner system, and there is a high chance of damage or failure over time. There can be various reasons for the damage, such as accidental use, sudden power surge, or electrical malfunction.

The easiest method to verify the reliability of the air conditioner is to check the warranty period allotted by the manufacturer. If you have a long warranty period, you can always have the option to avail free repairs or replacement from the manufacturer in case you face any sort of damage.

Conclusion

An air conditioner is a highly necessary electrical appliance in our day to day life. As these are hundreds of different options available in the market, you might get confused between a couple of products. To avoid that, we have shortlisted the best options available for you and provided a detailed analysis of each option. We have also provided a buying guide to make sure you get the perfect match according to your requirement. But, if you want a quick suggestion, take a look at our top recommendations down below:
