Best Basement Window Air Conditioners Buyer Guide

To make a comparison between the various portable air conditioners on the market and identify the most suitable one for your needs, first evaluate its BTU (British Thermal Unit) and, that is, the unit of measurement indicates its 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. This will be accompanied by a separate BTU classification in the presence of a heat pump for heating.

In the case of the portable air conditioner, this is not a simple evaluation. 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 classes have a higher initial cost, which is gradually amortized over time thanks to the energy savings they can guarantee. A guide to choosing the best inexpensive portable air conditioner may be useful.

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, in fact, collects humidity from the air, which, unlike the fixed ones, must then be managed. In units with containers, the water is collected, and then it must be emptied periodically. When this fills up to its maximum limit, afloat switches off the air conditioner to avoid flooding.

But there are very convenient systems on the market in which the condensate is not produced at all since it is evaporated internally, 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. In fact, although the technology has gone a long way in this case too, the machine cannot be expected to be extremely quiet 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 portable ones, we are about 45 (minimum ventilation speed) up to 70 dB.

Eco-Friendly and Low Consumption

The advantages of the AN112 Silent are manifold; first of all, as can be seen from the name, its noise level is decidedly contained compared to other portable air conditioners of other brands, thanks to a maximum level of 50 decibels of sound emission.

As regards electricity consumption, however, the AN112 Silent stands on a solid A + in the energy efficiency class, helping to keep operating costs low; a further advantage is also given by the little environmental impact of this air conditioner, which uses propane R290.

A high-efficiency natural gas which, among other virtues, has to be completely free of CFC, HCFC and HFC, all substances highly polluting and harmful to the atmosphere, with the consequence of completely eliminating the detrimental impact on the ozone layer.

Efficient and Versatile

The De Longhi AN112 Silent portable air conditioner absorbs a power of 950 Watts and offers a maximum yield of 11,000 BTU / hour, just enough to adequately cover a medium-sized domestic environment, up to 110 cubic meters; it has various operating modes, including pure ventilation and dehumidification.

Also integrates an exclusive condensate recirculation system, which improves efficiency and reduces consumption, a thermostat, an electronic timer programmable up to 24 hours and a new CLI LED display, which allows immediate feedback on the comfort status.

The ease of use is also increased by the practical remote control, which allows you to control it remotely.

Conclusions

It is essential to focus attention on the most relevant characteristics to make the right purchase which, we repeat, are the power expressed in BTU, the consumption and the way the condensate is discharged; in this way, you can draw up a personal ranking of the best products on the market.

We have produced our ranking that you find listed below and consists of the five portable air conditioners, in our opinion, most valid of 2020, each accompanied by a review.
