Room Air Conditioners

Room air conditioners, sometimes known as window air conditioners, control the air circulation in a room rather than the entire building or home. If required to provide air conditioning when they are needed, room air conditioners are more affordable to maintain than central air conditioners rating, although their efficiency is virtually lower than that of central units.

Smaller room air conditioners such as those using less than 7.5 amps of energy can be charged into any 20 amp/115-volt circuit that is not combined with any appliances. Complex room air conditioners (drawing more than 7.5 amps) require their own 115-volt circuit.

Even though a central AC unit may be the best for most households, they are expensive and require a complicated set-up. They also cost more to maintain than a smaller room air conditioner. For that reason alone, when only a specific room or place of your home needs air conditioning, getting the best portable air conditioner is the best option. However there are several appropriate units for cooling a room or a place as well as other factors, so your purchase of a room air conditioner should not be in a hurry.

Types of Room Air Conditioners

The kind of room air conditioner you need depends on how much installation you are willing to do. This could be a very easy decision if you own your place but if you are renting, it will require a necessary approval from your landlord. The most popular and practical air conditioner is the window-mounted unit, see window air conditioner ratings. On the other hand, the wall mounted unit has a complex set-up, and the window/wall units allow either installation.

Most room air conditioners employ the split ductless or mini air mechanism. However, most AC units with this kind of system are more expensive, but are less disturbing than a full-blown central air conditioner unit.

Other types are the portable air conditioner and window air conditioners. It is important to compare portable air conditioners before making your selection in order to choose the best one for your needs.

Room Air Conditioner AC Capacity to Cool a Certain Coverage Area

Manufacturers of room air conditioners normally provide a detailed recommended cooling area for a given AC model and purchasing a unit that powerful enough to cool that room is very essential.

Purchasing an undersized AC unit is not a wise choice if you want comfort from heat and buying an oversized unit is a bad idea also. You will spend for a feature that you will not likely use and you might have some trouble getting just the right kind of air conditioning, as a very cold environment is not comfortable. You should take measurements of the room before you go buying and think as to whether combining rooms should be included.

Suggested Cooling Capacity & Coverage Area

Although the specifications might be different, these are the standard BTUs for a cooling area:

100-300 sq. ft. - 5,000 ?6,000 BTU
250-550 sq. ft. - 7,000 ?8,200 BTU
350-950 sq. ft. - 9,800 to 12,500 BTU

The capacity with the corresponding coverage area will give you a baseline and when you find the room air conditioner you need, confirm the coverage area with the recommended specifications for your unit.

Energy Efficiency to Save in Electricity Costs

Most appliances have the EnergyStar seal, which means you can save less in energy consumption over non-qualifying models. You should think about the EER rating. Air conditioning units for homes that have been verified by the AHAM or the Association of Home Appliance Manufacturers have an energy efficiency rating (EER).

The higher the rating, the less in maintenance cost. Thus, an air conditioner with an EER rating of 15 is cheaper to operate than with a rating of 7. Include a high EER rating with the EnergyStar seal and your new room air conditioner will be less expensive to maintain than other AC units, because its home air conditioning parts will last longer.

The required cooling capacity for a room air conditioner is based on the size of the room. Room air conditioners; basically have cooling capabilities that vary from 5,500 BTU per hour to 15,000 BTU per hour.

Proper consideration of the size is very essential for efficient air conditioning. A bigger and more complicated Ac unit is not needed because a unit that is too big will not cool a room evenly. A smaller unit operating for an extended time operates more effectively and is quite efficient at dehumidifying than a larger model that cycles on and off too often.
