Shoppers have the problem of making choice. They are confronted with the dilemma
of what kind of product to buy. That is why we have created this guide to help our
shoppers in making the right buying choice from their stand-point.
Here are key factors to consider so as to buy the right Air-conditioners (AC)
One of the things to consider when you want to buy an Air Conditioner is size of
where you want to use the AC for. You need measure the room area and this in
turn will determine the capacity of the Air conditioner to use.
The larger the room space the more capacity required from the AC. This you can
take to any SPAR shop and get the determined specification.
Before you buy an air conditioner it is right to know the dimensions and size of the
space or building to be conditioned. A measure of the room area can help you
determine required air conditioners capacity.
The type of building may also determine the type of air conditioner you will buy.
Understand that different air conditioners have different cooling capacities. In your
calculation, consider If there’s no wall or door separating the space where you want to cool
from an adjoining room, ensure these factor is included in the calculation because the air
conditioner will have to cool that space as well.
Hence, to cool a building with a lot of rooms, it is recommended to use a central air
conditioner than buying lots of units of Windows or Split unit air conditioners. But
then This is very expensive.
If you consider using a floor standing AC, determine the space it will be mounted on.
Measure the maximum space allowed for the air conditioner so as to buy floor
standing air conditioners that can fit within the measured space.
Also, If it is Window AC you wish to buy, measure the dimension of the window.
Ensure that the dimension of the AC will fit into your window dimension with little or
There are different types of air conditioners in the market today. You need to
determine the type of air conditioner that you need. The type of Air Conditioner can
be determined by the use.
There are four main types of Air Conditioners. These are
Unit Air Conditioners
Central Cooling System (Central Air Conditioners)
Portable Air conditioner (Floor Air conditioner)
Ceiling cassette air conditioners
Unit Air conditioners are self-contained. Once installed, it can operate independently.
These are the type of air conditioners you will usually see in homes.
Small and medium sized homes that do not need too many air conditioning points
use unit Air conditioners. They are more economical if few air conditioning points are
However, as the number of points required for cooling increase, the merits of a
remotely (or centrally) controlled cooling system become obvious.
In a Central cooling system, vents replace unit Air Conditioners. These vents are
then connected to a central cooling system. Central cooling systems are used in
If you live in a standard apartment or a small house, you will not be interested in a
central cooling air conditioning system.
Your interest will be on Unit Air Conditioners. Here are the different types of unit air
From the name, window Ac unit, it is mounted on windows. These air conditioner
models are usually cubic in shape, but are increasingly taking more attractive
shapes. They come in different capacities ranging from small to large 5,000
BTU (British thermal unit) which about 1.96Hp up to 12,000 BTU (4.72Hp)
Small Capacity window unit: Has capacity of 5,000 BTU-6,500 BTU. This
AC cools approximately 100 to 300 square feet. It the smallest, lightest and
Medium—Capacity windows unit: Ranges from 7,000 to 8,200 Btu. This Size
of AC cools approximately 250 to 400 square feet.
Large—Capacity window unit: Ranges from 9,800 to 12,500 Btu. This AC
cools between 350 and 650 square feet. Best for cooling a large room,
Price ranges from 55,000 Naira to 189,000 Naira. For latest models and prices of
Windows Air Conditioner visit any SPAR store nation wide.
Split Air conditioners came as a modification to the windows unit. They are called
split because its component is split into two. It has a part called the indoor unit and
the other part which is the out-door unit.
The two split parts are connected together by drilling a hole through the wall. Split
air conditioners allows the installation of air conditioning without blocking off your
Price for this units range from 65,000 Naira to 250,000 Naira. For latest models and
prices of Windows Air Conditioner visit any SPAR store nation wide.
Portable Air conditioners are intended for places in which window
configurations or building designs prevent installation of window units. The
portable air conditioners in our tests range from 9,000 to 15,500 BTU.
They need to be placed near a window or semi-outdoor location in order for the hot
air to be released out and away while the cool air is blown into the house.
The floor standing air conditioners (or portable air conditioners) models are mounted
on the floor. Though they are called portable air conditioners, they are actually
There portability is as a result of not being fixed (or attached) to a wall or window.
Their position can easily be changed at any time. Some may even come with wheels
to make movement easy.
Price for portable units range from 150,000 Naira to 1,900,000 Naira. For latest
models and prices of Split Air Conditioners, visit any SPAR store nation wide.
Most people do not know about this type of air conditioners. They are mounted on the ceiling with the vents facing the ground. From top, they can circulate air more efficiently.
Ceiling cassette air conditioners come in high capacities and are designed for larger rooms.
Due to its design nature and bulkiness, they require expert installation. The duct from the air conditioner has to be run through the wall to the condenser unit located outside.
Capacities can range from 18,000 BTU to 55,000 BTU.
After knowing the room space size, you need to determine the capacity of Air
conditioner to efficiently and effectively cool and condition the required space.
An air conditioner with a larger capacity used for a small space will cool it’s target
space too soon leading to intermittent on/off switching of the AC. This has negative
wear and tear on the AC parts.
If you use a small Air conditioner of lower capacity to cool a larger space than
required, such AC will struggle to cool the space.
In addition a big air conditioner will consume more electricity than required
unnecessarily increasing your energy bill.
Some capacity ratings used for air conditioners include Btu (British thermal unit) and
Horse Power (hp).
BTU is a measure of the quantity of heat that an AC can remove from a given space.
The higher the Btu capacity of an air conditioner, the stronger it is. Btu capacity of
air conditioners, ranges from 5000 BTU to more than 90,000 BTU.
Btu may be popular in countries like in the United Kingdom, but in Nigeria it is
Horse-power that is used to describe air conditioners capacity.
The hp rating of an air conditioning system is about the power of the compressor of
the AC. The more powerful the compressor of an air conditioner, the greater its
capacity to cool (or remove heat from) a given space.
Popular air conditioner HP capacities in Nigeria are 1 hp (~2,500 BTU/h), 1.5 hp
(~3,900 BTU/h) and 2 hp (~5,000 BTU/h).
There are a number of recommendations for determining the air conditioner Btu or
hp capacity required.
A small room of about 12 square meters (130 square feet) or less requires about
2,500 Btu/hour or 1 hp.
A medium sized room of about 18 square meters (200 square feet) or less will
require about 3,900 Btu/hour or 1.5 hp.
A large room of about 30 square meters (325 square feet) or less will require
between 5,000 and 8000 Btu/hour or 2 HP.
It is important to ensure that the AC you intend to buy conform to local electrical
standard. One of the most important power ratings is the Voltage supply.
In Nigeria and most African country the voltage supply is 220-250V, 50Hz.
Other countries like Uk have power supply voltage rating of 110-115V, 60Hz.
Some air conditioners are smart enough to sense the voltage level and can operate
over a wide range of voltage (say 90-250v).

are varies from country to country. Here in Nigeria, we got brands like Midea, Haier
