Guide For Those Shopping for Air Conditioners
Here are some concerns to help you purchase the right A/C:
What room space
Before
you purchase an air conditioner it is right to understand the dimension
of the space to be trained. A assess of the room locality can help you
work out needed air conditioners capacity. The larger the room space the
more capacity required from the A/C. You need to take this space
information to the electrical devices shop.
If you are to buy a
floor standing A/C, you must furthermore determine the space it will be
climbed on on. assess the maximum space allowed for the air conditioner;
take it along with you to the Electronic shop. purchase floor standing
air conditioners that can fit inside the assessed space.
If you
propose buying window mounted air conditioners, assess the dimension of
the window. Take along your estimation with you to the electrical
devices shop. Ensure that the dimension of the A/C will fit into your
window dimension with little or no civil work.
What type and use
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 two main types of Air Conditioners. These are
- unit air conditioners
- central cooling system
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 homes that do not need too many air conditioning
points use unit Air conditioners. They are more economical if few air
conditioning points are required.
However, as the number of points required for cooling increase, the
merits of a remotely 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 larger houses.
If you live in a small apartment or a small house, you will not be interested in a central cooling air conditioning system.
Unit air conditioners come in different types.
There are window mounted air conditioners models. These air conditioner
models are usually cubic in shape, but are increasingly taking more
attractive shapes. As their name implies, window air conditioners are
mounted on the window.
There are also the High wall split air conditioners units. These models
are usually cuboids they are more classy than the window models. They
can be mounted on a window but are usually mounted higher than
conventional window A/Cs.
The floor standing (or cabinet) air conditioners models are mounted on the floor.
Ceiling mounted air conditioners are also available.
What Capacity BTU HP EER
You need to know the right capacity of air conditioner required to
adequately cool and condition the measured space. It is very important
to buy air conditioners with the right capacity. An air conditioner with
a larger capacity than required will meet its targets too soon leading
to intermittent on/off switching of the AC with negative wear and tear
on the A/C parts.
On the other hand, an air con of a lower capacity than required will struggle to cool the space.
The capacity of an air conditioner is a measure of its ability to cool a
given space. 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 A/C can remove from a
given space. Scientifically Btu is the quantity of heat required to
raise the temperature of one pound of water by one degree Fahrenheit.
The higher the Btu capacity of an air conditioner, the stronger it is.
Btu capacity of air conditioners, range from 5000Btu to more than
90,000Btu.
Btu may be popular in countries like the US and UK, but in others like
Nigeria it is not usually used to describe air conditioners.
A popular rating used by retailers in Nigeria is the hp (horse power).
This is a measure of the strength of an air conditioner and is somewhat
related to the Btu. The hp rating of an air conditioning system is all
about the power of the motor (compressor) inside the A/C. The more
powerful the motor of an air conditioner the greater its capacity to
cool a given space.
Popular air conditioner HP capacities in Nigeria are 1 hp, 1.5 hp and 2 hp.
There are a number of recommendations for determining the air conditioner Btu or hp capacity required.
A small room of about 12 square metres (130 square feet) or less requires about 5,000 Btu/hour or 1 hp.
A medium sized room of about 18 square metres (200 square feet) or less will require about 6,000 Btu/hour or 1.5 hp.
A large room of about 30 square metres (325 square feet) or less will require between 7000 and 8000 Btu/hour or 2 HP.
Another important rating to consider for air conditioners is the EER
(energy efficiency ratio). EER is a measure of how efficiently the air
conditioner operates. EER is the Btu of heat removed by an A/C per watt
of power consumed.
Mathematically,
EER = Btu/Power (in watts)
An A/C with higher EER will have a lower operating cost compared with an
air conditioner with lower EER. However EER comes at a cost. High EER
means you will have to spend more money. In other words, high EER air
conditioners are more expensive.
You must strike a balance between running cost and purchase cost. If the
air conditioner will be on always, buy one with high EER otherwise high
EER may not be worth it.
Power Requirement
It is important to ensure that the A/C you intend to buy conform to
local electrical standard. One of the most important power ratings is
the Voltage supply.
In the US the power supply voltage rating is 110-115V, 60Hz. Any air
conditioner for the US must meet these criteria. In the UK, Nigeria and
most African country the voltage supply is 220-250V, 50Hz.
Air conditioners require large amount of power so you may need to
install a dedicated power switch for it. Buy a socket or switch that can
handle the power requirement of the air conditioner.
Some air conditioners are smart enough to sense the voltage level and can operate over a wide range of voltage (say 90-250v).
Brands of Air conditioners
There are lots of
A/C brands
in the world and their popularity varies from country to country. In
the US and UK there are popular brands like Sharp, Whirlpool, Amana,
General Electric and so on. These brands are not so popular in Nigeria.
Some popular brands of air conditioners
with good reputation in Nigeria are Panasonic, Kingsmen, Samsung, LG,
Midea, Haier Thermocool, Airflow, Newclime, dizengoff and so on.
other A/C features to consider
Here are some other features to consider in air conditioners
- Bacteria/germ/odour elimination (clean safe air): example Silver Nano from Samsung, Nano Titanium from Hitachi
- Adjustable thermostat
- Variable Fan speed
- Slide out filter: for easy maintenance and cleaning
- Digital temperature control
- Sleep settings
What Price
Once you have a fair idea of the air conditioner you want to buy, you should then find out the
price.
Prices of air conditioners increase as capacity and number of features
increase. You need to do a market survey to determine the price options
available to you.
Call or visit an authorised air conditioner dealer to determine prices. Note that
prices of air conditioners also vary across brands.

Prices of most popular cooling systems in Nigeria range from N30,000 to 80,000 Naira.
Consumer Financing
Now you know the price of your A/C, you need to determine how to finance
it. Air conditioner financing may be available to assist you in buying
the new product. Enquire from your bank about financing options
available to you. In countries like the US and UK product financing is
more common than those in Africa like Nigeria. However, today consumer
financing is now increasingly available in most of the leading banks in
Nigeria.
Product financing is flexible and convenient but comes at the cost of
interest. So you may choose to buy with no credit financing.
Important Notes
Once you are sure of what you want to buy and you have a good idea on
price, you can then visit an authorised dealer shop to make your air
conditioner purchase. You may buy from any of the same shops you did
your market survey preferably the one with the best deal.
However, wherever you buy make sure it is from an authorised air conditioner dealer shop.
Authorised A/C dealers
deal directly with air conditioner manufacturers and will often offer
you a one to three years warranty. The warranty often involves repair or
outright replacement of the air conditioner if it develops any fault
during the tenor of the warranty. The fault must not be as a result of
your carelessness or abuse. The warranty is often limited so clarify
what the warranty includes and excludes (terms and conditions).
