The Best Window Air Conditioners in 2022

A win­dow air con­di­tion­er is the most effi­cient way to cool a room for lit­tle mon­ey. KP and expert Kir­ill Aksen­ov tell how to choose the best win­dow air con­di­tion­ers in 2022

Win­dow air con­di­tion­ers are an excel­lent option for inex­pen­sive cli­mate con­trol equip­ment. Air con­di­tion­ers of this type are able to main­tain the opti­mum tem­per­a­ture in rooms rang­ing from 10 to 40 sq.m. They are com­pact and easy to oper­ate. The dimen­sions of most win­dow air con­di­tion­ers cor­re­spond to the size of a stan­dard win­dow.

The main dif­fer­ence between win­dow-type air con­di­tion­ers and split sys­tems is the design, which con­sists of one work­ing unit (monoblock), which is eas­i­ly mount­ed in the win­dow. Win­dow air con­di­tion­er eas­i­ly turns into a mobile one, it is enough to remove the device from the win­dow of the apart­ment and install it in the win­dow frame, for exam­ple, of a coun­try house.

The monoblock is divid­ed into two parts, one of which goes out­side, and the sec­ond is inside the room. Parts of the win­dow split air con­di­tion­er are sep­a­rat­ed by a sealed par­ti­tion. The prin­ci­ple of oper­a­tion is quite sim­ple: the monoblock pass­es air through itself, cool­ing or heat­ing it. To install the device, it is often not nec­es­sary to resort to the help of a spe­cial­ist, but it is worth remem­ber­ing that a win­dow air con­di­tion­er can­not be installed in a mod­ern dou­ble-glazed win­dow if an appro­pri­ate hole has not been pre­pared in it in advance.

Win­dow air con­di­tion­ers dif­fer from their more mod­ern coun­ter­parts, split sys­tems, in high noise lev­el, often in a small area of ​​the refrig­er­at­ed room and a small set of func­tion­al­i­ty. The noise lev­el varies from 43 dB to 61 dB. Win­dow air con­di­tion­ers are quite pow­er­ful and heavy struc­tures: the aver­age cool­ing flow pow­er is 1460 W, the aver­age weight is 25 kg.

In addi­tion to the pos­si­bil­i­ties direct­ly relat­ed to the main pur­pose, mod­ern air con­di­tion­ers can also pro­vide very spe­cif­ic func­tions: fresh air intake, ver­ti­cal blinds dri­ve, self-diag­no­sis, auto-restart, etc. For ease of con­trol, a remote con­trol pan­el and a mon­i­tor with tech­ni­cal data can be pro­vid­ed. .

It is worth pay­ing atten­tion to the most com­mon refrig­er­ants used in air con­di­tion­ers: R22 and R410A. So, for exam­ple, the R22 refrig­er­ant most com­mon in win­dow air con­di­tion­ers is envi­ron­men­tal­ly unsafe (it harms the ozone lay­er), but it is prac­ti­cal — in case of a leak, you do not need to change the entire refrig­er­ant, just add the right amount. Its com­peti­tor — R410A com­bines three key advan­tages: effi­cien­cy, envi­ron­men­tal friend­li­ness and uni­for­mi­ty. How­ev­er, this type of refrig­er­ant is quite expen­sive.

Kom­so­mol­skaya Prav­da com­piled a rat­ing of the best win­dow air con­di­tion­ers in 2022 and ana­lyzed in detail the fea­tures of each.

Gree GJC12AF-E3NMNC1A. Pho­to: yandex.market.ru

Monoblock Gree GJC12AF-E3NMNC1A is designed for large rooms up to 35 sq.m. Due to the high pow­er of the cool­ing flow, the air con­di­tion­er quick­ly cools the air in the apart­ment.

The device is equipped with an auto-on timer and an auto-restart func­tion. After the pow­er is restored, the device will start oper­at­ing in the same mode as before the pow­er out­age. Thanks to auto-mov­ing ver­ti­cal lou­vers and four-sided dis­tri­b­u­tion, the air flow in a large vol­ume is dis­trib­uted even­ly through­out the room.

>

>

The device con­sumes a lot of elec­tric­i­ty due to the high pow­er con­sump­tion dur­ing cool­ing. The refrig­er­ant used is R410A, an expen­sive, envi­ron­men­tal­ly friend­ly mate­r­i­al with high oper­at­ing pres­sures that requires a robust and reli­able cool­ing cir­cuit.

Sam­sung AW 05 NOB. Pho­to: yandex.market.ru

The Sam­sung AW 05 NOB win­dow air con­di­tion­er is a light­weight and com­pact unit with medi­um room cool­ing capac­i­ty and low pow­er con­sump­tion. The air con­di­tion­er is designed for rooms with a small area — up to 15 sq.m. This mod­el has an opti­mal set of nec­es­sary func­tions: cool­ing, dehu­mid­i­fi­ca­tion, oper­a­tion in the exhaust ven­ti­la­tion mode.

Thanks to the “air mix­ing” func­tion, Sam­sung AW 05 NOB mix­es fresh air from out­side with the air passed through the air con­di­tion­er, thus not only chang­ing the tem­per­a­ture and humid­i­ty of the air, but also refresh­ing it. This func­tion is quite rare, since the admix­ture com­pli­cates both the design of the air con­di­tion­er itself and its instal­la­tion. The dis­ad­van­tages of this win­dow air con­di­tion­er include non-envi­ron­men­tal­ly friend­ly and cheap R22 refrig­er­ant.

Main characteristics

Room area 15 sq. m.
Cool­ing flow pow­er 1470 W

TCL TAC-05CW/A. Pho­to: yandex.market.ru

The win­dow TCL TAC-05CW/A is suit­able for a room with a small area — 15 sq.m. The mod­el pro­vides cool­ing and dehu­mid­i­fi­ca­tion as stan­dard. The pow­er of the device is low, so the pow­er con­sump­tion is low, the advan­tages are: low weight, mul­ti-speed fan and the “auto-restart” func­tion.

Night mode pro­vides cool­ing dur­ing the late hours, while the vol­ume of the device will be low­er than usu­al. The air con­di­tion­er uses R410A refrig­er­ant, which is safe for the ozone lay­er.

Main characteristics

Room area 15 sq. m.
Cool­ing flow pow­er 1500 W
Pow­er con­sump­tion in cool­ing 536 W

KRAFT AW-12 GW/H. Pho­to: yandex.market.ru

The com­pact and light­weight KRAFT AW-12 air con­di­tion­er does not effec­tive­ly cool the room, since the pow­er of the cool­ing flow is quite small. How­ev­er, the device is equipped with two impor­tant func­tions — nor­mal and forced ven­ti­la­tion. At least the air in the room will be well ven­ti­lat­ed.

The main dis­ad­van­tage is the high noise lev­el — 61 dB (sim­i­lar to a TV oper­at­ing at an aver­age vol­ume lev­el). The cheap refrig­er­ant R22, which is unsafe for the ozone lay­er, is used.

Main characteristics

Cool­ing flow pow­er 1465 W
Pow­er con­sump­tion in cool­ing 570 W
Max­i­mum noise lev­el 61 dB
Air flow 3.67 cu. m/min
The weight 20 kg
Dimen­sions 41 x 30 x 34 cm

The device is suit­able for rooms up to 18 sq.m., does not cre­ate a lot of noise and does not take up much space. It is quite easy to con­trol the air con­di­tion­er: in the arse­nal of the device there is an LCD dis­play and a remote con­trol. The undoubt­ed advan­tage of the air con­di­tion­er is the auto-adjust­ment of hor­i­zon­tal blinds.

The device itself diag­noses mal­func­tions and errors in its work, cleans the air of dust and dirt thanks to wash­ing and dust fil­ters, and also main­tains the opti­mum tem­per­a­ture in the room with­out the inter­ven­tion of the own­er. The dis­ad­van­tages include the lack of an on and off timer, although the pres­ence of a “night mode” will smooth out these short­com­ings.

How to choose a window air conditioner

Win­dow air con­di­tion­ers are not in high demand these days, so don’t expect a vari­ety of col­ors and shapes on the shelves of hard­ware stores. How­ev­er, this has a sig­nif­i­cant plus — you do not have to stand at the counter for a long time in thought. How­ev­er, some of the tips from the arti­cle are still bet­ter to use.

Accord­ing to KP, the ide­al win­dow air con­di­tion­er:

  • Cools effec­tive­ly and quick­ly. It is also desir­able that he him­self “under­stands” at what point to stop, and at what point to increase the pow­er to full.
  • Com­pact and light­weight. The main advan­tage of a monoblock is its mobil­i­ty. So that you can use one device to cool the apart­ment and, for exam­ple, take it with you to the coun­try house for the week­end. Remote con­trol, LCD dis­play, var­i­ous auto­mat­ic mode set­tings will save valu­able time.

For a deep analy­sis of the key char­ac­ter­is­tics, Kom­so­mol­skaya Prav­da turned to an expert in the field of real estate repair, the host of the Bad Repair pro­gram on the Aksen­ov-TV YOUTUBE chan­nel Kir­ill Aksen­ov.

The first ques­tion to answer when choos­ing a win­dow air con­di­tion­er is: in which room will the air con­di­tion­er be installed, what is its area? The answer to this ques­tion depends on the dimen­sions and pow­er of the struc­ture. For a 15 sq. m, you can use an air con­di­tion­er with a capac­i­ty of 1.5 kW., but if the win­dows face the sun­ny side, then it is worth increas­ing this fig­ure by 15%. When choos­ing an air con­di­tion­er, it is worth pay­ing atten­tion to the ener­gy effi­cien­cy class: always choose an A + device and above.

If the room is small, then the size of the equip­ment is impor­tant: installing a large monoblock in a small room is fraught with the dis­com­fort of being in the room when the mode is on, and dis­so­nance in appear­ance. Par­tic­u­lar atten­tion should be paid to the instal­la­tion process of the struc­ture: fol­low the man­u­fac­tur­er’s rec­om­men­da­tions dur­ing instal­la­tion. Pay atten­tion to the archi­tec­ture of the build­ing, its appear­ance: is it pos­si­ble to use a win­dow air con­di­tion­er.

>

>

Next, you need to decide where do you plan to install the struc­ture? Inside the win­dow open­ing or the bot­tom of the win­dow? Depend­ing on the answer, the func­tion­al char­ac­ter­is­tics of dif­fer­ent mod­els can be dis­tin­guished.

For exam­ple, if you plan to install an air con­di­tion­er in a win­dow open­ing, it will be con­ve­nient to use a remote-con­trolled mod­el to switch oper­at­ing modes and reg­u­late oper­a­tion in gen­er­al.

When installed at the bot­tom of the win­dow, use with­out a remote con­trol is pos­si­ble.

Mod­ern designs of win­dow air con­di­tion­ers have dif­fer­ent ven­ti­la­tion modes, humid­i­ty lev­els, remote con­trol (smart home sys­tem), up-to-date design and the abil­i­ty to heat the room, thanks to the reversible com­pres­sor option (but at a “gen­tle” out­door tem­per­a­ture, up to ‑3 degrees Cel­sius) .

Accord­ing to the expert, the main para­me­ters when choos­ing:

  1. Room area
  2. Power/cooling capac­i­ty
  3. Noise lev­el
  4. Ener­gy effi­cien­cy class
  5. Mount­ing
  6. Addi­tion­al options

Popular questions and answers

What are the advantages and disadvantages of a window air conditioner?

Advan­tages: Win­dow air con­di­tion­ers are usu­al­ly installed in a win­dow open­ing (hence the name) or a build­ing wall, the width of which is no more than 30 cm. Their essen­tial plus is ease of instal­la­tion and use. Demand for an afford­able price (usu­al­ly 30% low­er than the cost of a split sys­tem) and sim­ple main­te­nance.

Anoth­er plus: sup­ply ven­ti­la­tion (in split sys­tems this func­tion is very rare and increas­es the cost of the prod­uct), the absence of main ele­ments, unpre­ten­tious oper­a­tion, refrig­er­ant leak­age is prac­ti­cal­ly exclud­ed.

Flaws: Oper­a­tion in the “warm” peri­od; increased noise lev­el; instal­la­tion is not pos­si­ble in all win­dow frames; aes­thet­ic com­po­nent, not every­one likes such designs. If you like silence and do not allow extra­ne­ous noise, then it is bet­ter to choose a split sys­tem.

When does it make sense to install a window air conditioner, and not a split system?

A win­dow air con­di­tion­er will save a fam­i­ly bud­get and be rel­a­tive­ly easy to install, which is suit­able for those who want to do the instal­la­tion them­selves, accord­ing to Kir­ill Aksen­ov. But the choice is always indi­vid­ual.

How to maintain a window air conditioner?

From the out­side, keep the struc­ture clean: remove leaves in autumn, snow in win­ter — elim­i­nate the effects of bad weath­er and the result­ing debris. For clean­ing, you need to open the exter­nal unit, if you can’t get to the met­al blades, then at least gen­tly wipe the sur­face. Every­thing should be clean and free of for­eign objects, the expert rec­om­mends.

Fol­low the man­u­fac­tur­er’s instruc­tions for use. Fil­ter clean­ing should also be described in the prod­uct instruc­tions: as a rule, it is cleaned in the spring and the monoblock is reg­u­lar­ly wet cleaned. Heat exchang­er plates made of met­al are best washed with water. When clean­ing the struc­ture, be care­ful not to dam­age the parts.

As a rule, win­dow air con­di­tion­ers do not require “refill­ing”, due to the design fea­tures in gen­er­al. To check the con­di­tion of the device, as well as main­te­nance, it is bet­ter to con­tact a spe­cial­ist. It will not work to fill the air con­di­tion­er on your own, all con­nec­tions are sol­dered, and if a leak occurs, then only the mas­ter will iden­ti­fy the leak and fix the prob­lem.
