How to Choose Best Low Profile Window Air Conditioners

To combat the heat and the summer heat, the portable air conditioner is an excellent alternative to fixed systems. It is preferred for its greater practicality and ease of installation, and the lower price.

However, despite being a less complicated appliance than the fixed ones, it still has several variables that must be carefully analyzed before purchasing and thanks to a guide like this it is possible to get a clearer idea on which portable air conditioner to choose.

Btu / Consumption

To make a comparison between the various portable air conditioners on the market and identify the one that is most suitable for your needs, first of all, evaluate its BTU (British Thermal Unit) and, that is, the unit of measurement that indicates their power.

You will need to choose the right appliance based on the size of the room you want to air-condition and other parameters (exposure to the sun, number of windows present, etc.) keeping in mind that a too-small machine will not be able to cool effectively.

On the contrary, a too-large unit will not be able to remove the right amount of moisture from the air. In the presence of a heat pump for heating, this will be accompanied by a separate BTU classification.

In the case of the portable air conditioner, this is not a simple evaluation because, unlike the fixed one, the rooms to be cooled can be different.

Closely related to the power of the portable air conditioner is its consumption. Today it is mandatory to indicate on the label the energy class in which each machine falls (ranging from A +++ to D), and this becomes one of the most relevant parameters to consider.

Portable air conditioners with more efficient energy class have a higher initial cost which is gradually amortized over time thanks to the energy savings they can guarantee.

Condensate Drain

To choose the appliance that best suits your needs, some compare prices, BTU and consumption and who, on the other hand, is most interested in its practicality and maintenance.

The portable air conditioner collects humidity from the air which, unlike the fixed ones, must then be managed. In units with containers.

The water is collected and then periodically emptied. When this fills up to its maximum limit, afloat switches off the air conditioner to avoid flooding.

But there are very comfortable systems on the market in which the condensate is not produced at all since it is evaporated internally, therefore leaving no water to be removed.

In other cases, the condensate is entirely or partially eliminated by evaporation outwards through the drainpipe, so it will rarely be necessary to empty the container.

There are not many units that can boast these functions and the best brand of portable air conditioners, for someone, maybe precisely that which offers the latest developments in technology.

Silent

For others, however, the best portable air conditioner on the market may be the quieter ones. Although the technology has gone a long way in this case too.

The machine cannot be expected to be extremely silent because the engine that cools/heats, unlike the fixed air conditioners, is located inside the house.

We must, therefore, pay attention to two critical parameters which are the minimum noise level and the maximum noise level declared.

A silently fixed air conditioner also reaches around 20 dB of noise, in the case of portable ones we are about 45 (minimum ventilation speed) up to 70 dB.

The Consumption

One of the first aspects that are evaluated when choosing the air conditioner to be installed in the home is that of consumption. Under the lens also the power of the appliance which must be able to cool and heat the house, according to the seasons.

This parameter is indicated in Btu, that is the British thermal unit. The selection between the appliances must also be made taking into account the cubic meters that the air conditioner must go to air-condition—the discourse changes when the environments are huge.

The Models

The choice of a quality air conditioner must be made, especially taking into account the needs of those who buy it and the environment in which this appliance will be installed.

Both in the home and at work, by now, the air conditioner has become a strong ally which it is difficult to do without in both the winter and summer seasons.

There are many models on the market according to the different needs and the location that will host the air conditioner.

On-Off and Inverter Technology

The air conditioners on the market are divided into two main categories: On-off and Inverter. The first group includes older products that are easier to use.

These are devices that have a lower cost but also higher consumption. Furthermore, these items do not always ensure proper comfort for tenants in the home.

A different matter for Inverter air conditioners that instead emit air – both hot and cold – according to a more intelligent system and which optimizes electricity consumption.

These devices manage to ensure excellent performance while using energy to a minimum. Another function almost always present in these types of systems, beyond dehumidification, is that of ventilation.

This type of option is advantageous when the external thermometer rises a lot, and the heat becomes unbearable. One does not buy a fan because the air conditioner performs its same function.

The inverter air conditioners are also equipped with a timer: it is possible to program the switching on and off and therefore finds the desired temperature when returning home.

Conclusion

For all these functions it will be useful to study the instruction booklet and of course the remote control.

The air conditioners with On-Off technology are therefore suitable for those who do not feel the need to keep the air conditioners always on and who may even live in smaller rooms. They certainly cost less, but the same savings will no longer be present on the bill.

The air conditioners with Inverter technology are instead recommended for those who want to air-condition their room at home for long periods.

Some keep it on at night, those during the day for all three summer months. Although these air conditioners remain on for several hours, consumption is not so high, and the savings on the bill will be evident when compared to that of an apartment in which an on-off air conditioner is used.
