Best 5000 BTU Air Conditioners in 2021 [Top Rated]

An air conditioner is a system that removes heat from the moisture of the air to improve the comfort of the occupants in that certain space. It is also used to dehumidify rooms filled with heat-producing items or devices. This can be found in the air-conditioning units usually found in our homes or offices. These units come in several types or models.

AC Unit Models

There are six types of air conditioners available for commercial use. They are: the central units, ductless mini split units, window units, portable units, hybrid air conditioners, and the unit with geothermal heating and cooling. Each of the AC units have different purposes and for different locations as well. However, most of them are switched on via remote control.

Central Air Conditioners

Central AC is a type of AC unit. They circulate cool air through a system of supply and return ducts. Supply ducts and registers (openings in the walls, floors, or ceilings covered by grills) carry cooled air from the unit to the home. This cooled air becomes warmer as it circulates through the space; then it flows back to the unit through return ducts and registers.

Even these air conditioners have different types in this sub-category. In a split-system central AC, there is an outdoor metal cabinet that contains the condenser and compressor, and an indoor cabinet, which contains the evaporator.

In many split-system air conditioners, this indoor cabinet also contains a furnace or the indoor part of a heat pump. The air conditioner’s evaporator coil is installed in the cabinet or main supply duct of this furnace or heat pump.

A split-system is most practical if the home has neither a furnace, nor an AC. In a packaged central air conditioner, the evaporator, condenser, and compressor are all located in one cabinet, which usually is placed on a roof or on a concrete slab next to the house’s foundation.

This type of air conditioner also is used in small commercial buildings. Air supply and return ducts come from indoors through the home’s exterior wall or roof to connect with the packaged air conditioner, which is usually located outdoors.

Packaged air conditioners often include electric heating coils or a natural gas furnace. This combination of air conditioner and central heater eliminates the need for a separate furnace indoors. This is most sensible when the house has its own furnace.

Ductless, Mini-Split Air Conditioners

Considered as the most commercialized unit, these are the ones you may find most commonly used in households and offices. The ductless, mini-split AC works just like the central units but has different components. It has an outdoor compressor and an indoor air-handling unit.

Such ACs have a conduit connected to it from the outside to the inside, housing the power cable, refrigerant tubing, suction tubing, and a condensate drain. Although they are quite popular, here are some of the advantages and disadvantages that can be laid out.

One of the pros of this AC unit is, it consumes less space in the home, as it is usually attached to the top corner of one wall. Many models can have as many as four indoor units connected to one outdoor unit.

The amount of units relies on how much heating is required for the building. Each of the buildings or zones has its own thermostat, so you only need to condition on that space when it is occupied, saving energy and money.

Since it is smaller than other ACs, it would be a lot easier to install than those other types. Also, the outdoor unit can be 50 feet away from the indoor evaporator, due to connections with the conduits, which eases the hassle of installing the air conditioner.

This makes it possible to cool rooms on the front side of a building house with the compressor in a more advantageous or inconspicuous place on the outside of the building. Since mini-splits have no ducts, energy losses are decreased by more than half.

Duct losses account to 30% of the housing energy consumption, especially if the ducts are in an unconditioned space such as an attic. Last but not least, mini-split air conditioners ensure safety because from the outside to the inside, it only requires a small hole, which isn’t guaranteed by the window unit AC and the others.

However, even amazing products have disadvantages too, and one of them is the cost. This can be factored with the size, as well as the location of the installer.

All these require large investments for it to function properly over a long period of time. If placed or sized wrongly as well, the maintenance and usage would be very costly.

Window Units

A window unit air conditioner is sometimes referred to as a room air conditioner, whereby it is attached to a window, unlike ductless mini-split units. They are seen as bulky, but this is because all the components are cased inside.

This refrigeration unit has a double shaft fan motor with fans mounted on both sides of the motor. One at the evaporator side, and the other at the condenser side. The evaporator side faces into the room to release cool air, and the condenser side faces outside to release the hot draft of air from the air circulation.

Physically, it looks different from the other units as well, whereby all the components seem to look like they are packed together. The indoor components are: cooling coil, fan blower, capillary tube, operation panel, filter drier and the drain pan.

Then, the outdoor components are: the compressor, condenser coil, propeller fan, and the fan motor. Window units are still in use today, but there are some pros and cons regarding the usage of them. Some pros are they are more popular, and price comparisons are easier to find.

Other than that, window units tend to produce lesser noise, which meant lesser energy wastage, making it more energy efficient. Water drains from the unit to the exterior with no intervention needed, and also sends all hot air to the exterior as the warm air is exchanged for cold.

Smaller ones are able to adequately cool a space of 100-300 sq ft, and larger units can cool up to 650 sq ft of space. If carefully placed by the right window or wall, the AC can cool up to more than one room.

However, this compact device also carries several setbacks. The window used will be fully blocked, preventing view to the outside, and not all windows actually support the AC unit. As the water drips from the unit, it could be a disturbance to the pedestrians.

It is also a hassle to move the AC unit from one place to another. Some windows do not have an external support, which can be a hazard, whereby the window unit can fall off, or can be removed, bringing in another of a security problem.

Then, the panels that come with these units can let in a lot of hot air. Last but not least, the window unit does not help to improve the decoration or the aesthetics of the rooms.

Portable Units

A portable air conditioner is a unit that does not require permanent installation. It can be moved around the house,unlike the units mentioned prior. Commonly, portable units have wheels connected to them for ease of movement, and are generally very lightweight. They are most ideal for cooling single rooms.

Also, just as it looks, using a portable AC isn’t as complex as the others, and also it functions the same, which is to exchange warm air for cool air. The setup is also considered simpler than the other models. Usually, the unit comes with a window kit.

A window kit has a window slider and exhaust hose, to expel the heat outwards. Some select model ACs can also be vented into a drop ceiling or through a wall. Since portable units are connected to ducts usually, it has several ways to drain water. One of them is the fully self-evaporative method.

This is for advanced portable ac units. It automatically removes moisture by evaporating it out the hose along with warm air, which makes it more convenient, without needing to remove the condensed water. Another way is the gravity drain and condensate pump.

This requires a drain hose to be connected to the appliance, in order to collect the moisture from condensation, and direct the water into a drain. Lastly, it is the manual removal method, which is when buckets attached to the AC have to be emptied as often as every eight hours, one month once.

Buckets have to be emptied each time before using, which can be a hassle to users in general. Although portable units seem to be the best and most innovative version of the AC units, there are some setbacks as well.

The noise produced by the air conditioning is considered more disturbing than that of the window or central units, where it can drown out other noises, such as the television, or conversation. As mentioned, it is when water needs to be cleared out before using the air conditioner.

Just like its size, the portable unit is capable of cooling a room, but unlike the other units which can cool larger areas of space.

Hybrid Units

What does it mean by hybrid? It means that several forms of technology are being used to run an appliance. Generally, hybrid units run on solar power and electricity, hence called as solar-powered air conditioners too.

Hybrid units are said to be the ideal model for promoting eco-friendly usage, as it is energy efficient, and replaces battery power. Other than that, it also provides warm air during winter, portraying the dual method of the typical AC.

Since it is considered a new form of technology, it is likely that prices for each hybrid unit would be very costly, around $2000 per unit. It is also suitable for home use, but by price, other units would have proved to suffice.

Geothermal Heating and Cooling

Geothermal heating and cooling utilize a two-in-one HVAC system. A HVAC system stands for heating, ventilation and air conditioning. This system is well-known for household usage of providing heat or using air from the outside to cool your homes.

Since it is quite advanced, you should know that the system is not easy to install, as it is considered one of the most extensive house systems. There are nine parts in the HVAC system: air return, filter, exhaust outlets, ducts, electrical elements, outdoor unit, compressor, coils and blower.

The air return part involves air ventilation, the filter removes dust from the air, the exhaust outlet is where heat is removed, the ducts are where heated or cooled air passes, electric elements are the power supply for the HVAC, the outdoor unit is where the fan is for the air flow, compressors are where the gas will be converted to liquid to be passed to the coils, and last but not least, the blower, where warm air is drawn into the main unit. HVAC systems can last for several years.
