In pursuit of an ideal air conditioner, Haier is a company to consider, as it’s one of the largest manufacturers of appliances and consumer electronics in the world. Haier air conditioners are all about achieving a soothing, chilled atmosphere conditioned to a perfect, cool temperature.

After considering several options, we recommend the Haier ESAQ406P Serenity Series model. Its top features include four operating modes for optimum performance, a 24-hour timer with sleep mode, a dual motor for maximum air control, and a compressor blanket that ensures whisper quiet operation. While this one claims the best Hair air conditioner as the Editor’s Choice, there are two more models herein that you can also compare and decide which one will suit your needs best.

Mostly, people buy air conditioners based on their respective thermal capacity and control which is often measured in BTU (British Thermal Unit), their fan cooling speed, energy efficiency, size, and coverage area, etc. These features are key attributes that determine the quality and work efficiency of an air conditioner. For instance, every model mentions the size of area it can cool effectively, and paying attention to this number can help you pick the right one for your space. Now, this post is divided into a product comparison table, in-depth product reviews, and dedicated buying guide with essential information about how to choose an air conditioner.

Haier ESAQ406P Serenity Series

  • Type: window AC
  • BTUs: 6,050
  • Coverage area: 151–250 sq. ft
  • Dimensions: 21.25 x 9 x 12.44 in

Other features: 4 modes: Cool, Fan, Energy Saver, and Dehumidify; 11.2 EER efficiency; 24 h timer; dual-motor design; compressor blanket reducing noise; cross-flow fan; 43 dBA

The ESAQ406P Serenity Series Haier air conditioner comes with a compact design housing and four operating modes. This AC is from Haier window air conditioner collection which uses a 115 volts outlet and operates at 6,000 BTU. The BTU refers to the amount of temperature or heat that an air conditioner can cool down.

The coverage area for cooling ranges from 151 to 250 sq. ft, making it a suitable choice for a quiet air conditioner with a window installation option. Some of the customers suggested that it would be better to include paddings to muffle the vibrations produced by the side hinges, however, the air conditioner’s overall performance is quite satisfactory as per the reviews we analyzed.

The most important feature that everyone liked about this air conditioner is its multifunctionality. Featuring a muffling compressor for quiet operation, it offers a comfortable experience and easy installation ideal for small window openings.

It should be noted that the air vent and wing panel must be cleaned and filtered from time to time for smooth airflow and proper, regular cleanup. Though the wings are thin and bendable to access and dust out the dirt and debris easily, it is advisable to exercise caution while doing so.

Using an air cleaning gun to blow out the dust with pressure without having to touch can be a proper way of cleaning the air vent. With an energy efficiency ratio (EER) of 11.2, the Serenity Series Haier window AC is a highly efficient product with a competitive edge over its other rival units available on the market.

    What stands out?
  • Multiple fan modes: cool, fan, energy saver and dehumidify
  • Quiet operation
  • High energy efficiency; 11.2 EER
  • Accurate temperature display
  • Dual motor design for excellent air control
  • 24hr timer feature plus sleep mode
  • Includes compressor blanket for reduced sound
  • Compact and comfortable design
    What cons did we manage to find?
  • A part of the front panel doesn’t get fitted inside the window completely and sticks out a little

  • Type: portable AC
  • BTUs: 13,500
  • Coverage area: 600 sq. ft
  • Dimensions: 15.2 x 17.8 x 29.4 in

Other features: 3 modes: Cool, Fan, and Dehumidify; dual-hose design; digital control panel; full-function remote control; 24 h timer

The Haier Dual-Hose Portable Unit has a BTU rating of more than 13,000 and is a medium-sized dual-hose air conditioner.

The Dual-Hose houses a 115 V potential voltage support and an electronic control panel installed in the middle of the frontal face of the unit. These two hoses enable a quick cooling effect without exhausting the system by venting out the inner air. They are long enough to be extended outside the windows in any room, something that increases the efficiency and the overall capacity of the unit.

With sturdy caster wheels attached to the base, the easily movable Haier 13,500 BTU air conditioner becomes a go-to choice for those who are looking to buy something between Split AC and the window AC unit. Often known as chillers, these types of air conditioning equipment are ideally used during cozy dinners and family meetups scaling a small area up to 600 sq. ft. You can also move it within the house from room to room, wherever needed.

This Haier AC comes with a fully operational remote to control the thermostat, and offers three different functionality modes including fan, dehumidifier, and cooling mode, It also has built-in storage and a memory mechanism to remember the last-set mode in case of a power outage. With a 190 cfm capacity of airflow, the fan feature of the unit is responsible for air circulation and redirection in a smooth manner.

The only hiccup is that this model is not as quiet for you to sleep while it’s running. Apart from that, it’s a great product in the budget end.

    What are its best features?
  • Dual-Hose design to speed up cooling
  • Portable and easy to move thanks to caster wheels
  • Multi-functional with three modes: cool, fan and dehumidify
  • Electronic display for viewing temperature and time
  • Remote controlling mechanism
  • Integrated memory storage
  • Cleanable air filters
    What could be improved?

Things to Consider

Making a decision can be easier if provided with some guiding pointers and useful information. We have written this buying guide to answer your questions and concerns regarding the purchase of Hair air conditioning systems.

Why Haier?

3 Best Haier Air Conditioners for Those Who Are Looking for a Reliable AC Unit

Haier has been a renowned name in the home appliance industry and has emerged as a successful competitor for its rival brands. Established in 1984, they believe in making life beautiful by providing useful solutions to home necessities.

Their product range is quite diverse and has an extensive range of products to choose from in any particular category. Similarly, their range of air conditioners comprises user-friendly products with easy functionality and efficient performance. Haier is taking the initiative to introduce IoT technology in its major line of appliances including the Haier AC units.

Features to consider when choosing a Haier conditioner

Planning to buy a Haier AC unit? Below is your checklist to help you understand the quality and performance efficiency of a potential air conditioner.


Air conditioners are generally available in different types such as central AC units, window ACs, portable small-sized units, ductless split ACs, etc.

The central AC is used for spacious areas and open spaces such as living rooms, auditoriums, malls, offices, dining halls, and hotels. On the other hand, window ACs are mostly used in enclosed spaces such as houses or offices.

Portable models, such as the Haier 14000 BTU portable air conditioner, are also a favorite for moving between rooms due to their small, easy-to-handle and compact design. These can be placed anywhere where instant cooling is required without having to go for a large-scale buy.

Ductless AC units are split air conditioners which can be used in a windowless room by being mounted on the wall. Before buying a particular unit, you should know your requirements and area availability to understand which type would suit you best.


The BTU is a thermal unit for measuring the cooling capacity of the air conditioners. It is highly recommended to consider this feature before making your choice. The main purpose of any AC unit is to eliminate heat and bring a cooling effect to the desired area. So, it is important to select an AC unit with a high BTU capacity only if you have a larger area to cool.

On the other hand, if you only want to use the unit in a small apartment room or study area, you should select those with average BTU capacities such as Haier HPP08XCR 8000 BTU Portable Air Conditioner because you might not want to spend much on the extra billing the high capacity unit will charge or the over efficient performance that might go to waste.

Coverage area

3 Best Haier Air Conditioners for Those Who Are Looking for a Reliable AC Unit

The coverage area capacity of an air conditioner is one of the deciding factors for purchasing a particular air conditioning unit. You should know how much of an area can be cooled down by the AC unit and how much is your own requirement. Compare them both and see what suits you. For instance, an AC covering an area of about 600 sq. ft such as Haier 13,500 BTU 115V Dual-Hose Portable Air Conditioner, might be suitable for your 500 sq. ft sitting area but may not be deemed ideal for your 1,000 sq. ft gym room. Similarly, a small portable unit having a maximum coverage area of 250 sq. ft such as Haier ESAQ406P Serenity Series unit, may not be sufficient for your 600 sq. ft studio apartment.

Fan speed and cooling

The fans in air conditioners work to maintain the airflow and cooling effect without letting the unit exhaust itself. They are essential elements to keep the air conditioner from getting over-worked. Make sure that whichever product you buy has a dedicated fan mechanism to circulate the cool in the entire room with ease and efficiency. It also helps in low power consumption and decreases the energy load.

Operation modes

AC units usually have multiple operation modes such as fan or ventilation mode, the heating mode used as a heater in winters, cooling, or chill mode for hot weather, and dry mode for dehumidification. Most units facilitate multiple modes for added functionality just like what we have in Haier ESAQ406P Serenity Series, that is, four different operating modes, to maintain the desired temperature and switch over whenever needed.


The size of an AC unit is also a determinant in choosing the most suitable product according to the available space you have where you wish for the air conditioner to be installed. Whether you are going to buy a window AC or a ductless split system that can be installed on the wall, make sure to measure the dimensions of your space beforehand to be able to compare them with the size or your to-be-purchased unit.

AC size also helps determine the possible capacity, compressor size, and vent area of the unit which in turn will help you understand the potential work performance and efficiency of the product.


Hair offers a standard 2-year warranty for all their appliances. Any part which is found to be defective within the warranty period will be repaired or replaced without extra cost.


How long is the warranty for a Haier conditioner?

According to Haier’s official website listings, the warranty for Haier AC units is one year while the compressor’s warranty is 5 years. The one-year warranty includes free parts repair and replacement along with the engineering support service.

What is the best way to clean the air conditioner?

You can clean up your Haier air conditioner by first applying some coil cleaning liquid and spraying lightly on the vent to cool down the temperature in hot weather. Then proceed with the pressure-air-cleaning technique in order to dust off the gathered dirt particles on the air pane and panel area of your unit. Some would use a vacuum cleaner hose pipe for this purpose. Next, you try cleaning the airflow area from inside by taking out the air vent if it is removable.

Our verdict

The more we explore, the more endless the possibilities become. This guide only has our three best Haier air conditioners but there are certainly plenty of AC models that you can buy from this leading manufacturer. We sum up as follows.

Our very best Hair model is the Haier ESAQ406P Serenity Series. Perfect for small-medium range spaces up to 250 sq. ft, it boasts a 6,000 BTU capacity, high energy efficiency, and comes with plenty of modes for customized output.

If you are looking for a portable choice with quiet operation and a superb venting system supported by two hoses, you can go for the Haier 13,500 BTU 115V Dual-Hose Portable Air Conditioner. Moreover, it’s an inexpensive option.

On the lower scale of things, the Haier HPP08XCR 8000 BTU Portable Air Conditioner is perfect for small spaces. It can either mounted to the window or put on a raised surface in an easy-to-handle manner.

We hope that one of the Haier air conditioners above will meet your needs.
