The main reason to get an air conditioner is to keep your home colder when it is warm outside. But this is a complex system of controlling the air temperature, humidity, and cleanliness, as well as the movement of air in conditioned spaces. Here, we will provide a buying guide for ACs. This short guide is created to help you understand the basics of how this system work and to help you choose the right AC for you.

Background on air conditioners :-

Do you know that in reality, an ac is making your home ‘less warm’? A simple description of the process is that when air gets cycled through this system, heat from the air is absorbed by this system, and the cooler air is blown back into the room and/or throughout the house. Since this guide is not for engineers, we will skip the technical discussion of how this happens; curious minds can find out easily enough elsewhere.

Features and functions to look for in air conditioners :-

AC come in many shapes and sizes, but there are two main types of air conditioner, split AC and window ac. These systems are either self-contained and designed for single or multi-room use, or they are designed to cool the entire house in conjunction with the furnace and ductwork system. The most important feature of any air conditioning unit is measured in cooling capacity.

Cooling capacity is measured in BTUs or British Thermal Units. This figure represents the amount of heat required to raise or lower the temperature of one pound of water one degree Fahrenheit. The heat that is extracted from your home by an AC is measured in BTUs.

Split Air Conditioner :-

These systems are designed to work in smaller spaces, such as one room or one level of a home. The size of The room for this is very small. They can be the perfect solution in a variety of situations: you want to keep the baby’s nursery room cool, one room in the house gets particularly warm, you live in a ranch and only need one level cool, etc., etc.


 Single or multi-room units are also known as ‘window A/C units’ because they are installed in windows to allow the movement of air from the inside to the outside of the home. These air conditioners come in different capacities, usually somewhere between 5,000 and 30,000 BTUs.

Window Air Conditioner :-

These ACs are designed to work in conjunction with your home’s furnace/heating system to cool your home. Typically, a unit is placed outside the home and additional equipment is installed in your furnace. This is so the cooler air can be blown throughout the home via the existing ductwork that is directly connected to the furnace. 


Additionally, the air conditioning system will have to be connected to the thermostat or other control device to give you some way of controlling the settings on the air conditioner system. It’s also come in ton ac. Whole-house air conditioning systems typically come in capacities of 18,000 to 60,000 BTUs.

How to find the best air conditioner for you :-

Researching online is the best place to start when shopping for an ac. You may or may not be sure which type of air conditioner would be best for your situation, so researching specific models will help you narrow down your choices by price and capacity. Many air conditioners can be financed, either directly with the manufacturer/dealer, or sometimes with large retail chains (usually by opening up a store credit card.)

Capacity

The most important component to consider when looking for an AC is capacity. Unlike other appliances in the home, it IS possible to get ‘too much power’! A unit that is too large is not only more expensive to purchase and operate, but it also won’t work as well. If any system has too much capacity for your home, the air will cool quickly, but this could be counter-productive.


 This is because the moisture is removed as the air is pulled across the cooling coil in the unit. If an oversized unit cools the air too quickly, the unit shuts back down and there isn’t enough time for the moisture to be removed from the air and the inside will remain humid.

 On the other hand, choosing a unit that is too small is bad because it may not be able to do the job on some of the hottest days. Some companies also provide star rating for better experience. It would be possible to run the unit all day long but never achieve your desired cooling temperature.

Many of the top air conditioning manufacturers recommend that you do not leave the decision of capacity to chance or guesswork. As each home is different in terms of its ductwork, heating patterns, and layout, they recommend that you have an experienced professional determine the proper capacity air conditioner.

Where to buy best AC 

Most of the whole-house air conditioning systems are sold nationwide through the company and independent dealers and the larger home improvement stores. They will provide installation as well. 


Many of these dealers have excellent web sites that can give you all the information you need and even schedule appointments for estimates and installation. The single and multi-room ac units can be found at major hardware stores and require minimal installation.

Efficiency

Beyond capacity, you should consider the efficiency of a unit because this can help save you money over the life of the air conditioner unit. The electricity bill also matter with efficiency of ac. It’s better to go for 1.5 ton capacity.


 Don’t be fooled by marketing terms like ‘high efficiency’, though. Only believe on bureau of energy efficiency. The only number to compare efficiency is the SEER number, and the higher the better.

Warranty

Make sure to compare warranties among competing brands carefully. Do they include the same components, or is there a significant difference in coverage? Are any labor costs included in the warranty?

Humidity

If humidity is a problem in your area, find out what (if any) additional accessories need to be installed to control humidity.

Control

ACs are controlled by thermostats, which simply measure the temperature of the air and either turn on or turn off the air conditioner once the ambient air temperature has reached a certain level. You may have the option of getting a programmable thermostat, which gives you the ability to program various ambient temperatures based on time of day or day of the week. In indoor units, it good to focus on power consumption. For example, if no one was at your home during the day on weekdays, you could program the temperature to be a little bit higher, then have the ac cool the house back down to your desired temp for when you get home. Some systems even incorporate humidity controls into your system. Programmable thermostats can save you operating costs because the system is on less often.

Multi-Speed

Air conditioning units that have more than one speed are generally more efficient than single-speed units because don’t have to use more energy than needed.

Sound

Some acs are noisier than others, and if this is a concern for you, make sure to hear the unit in action before settling on one model by considering noise level.

Finding a dealer or model
OK, you’ve done your research, you’ve found what you think is the type of air conditioner that you want, know the features that are important to you, what range of capacity you’ll need and what price range you’re probably in. What next?

To find the specific model or dealer, it might pay to ask your friends and colleagues if they have had any experience with dealers or if they like or dislike their conditioning system. Instead of or in conjunction with personal referrals, you can find out if any of the ac.
manufacturers, dealers, or models have earned the endorsement of any legitimate, third-party rating entity. Finally, you may consider a brand name as a criterion. Generally, the best-known and most successful businesses are those that do a good job, earn a good reputation and earn repeat business.

Split Air Conditioner – Operating Tips:

To save electric energy and keep rooms cool do the following when using a room air conditioner:

Turn off any light and electric equipment that are not required as they generate heat.

Make sure that doors and windows are closed to keep the cool air inside the house.

Select the thermostat setting as desired. A temperature of 25.5Β°C is usually recommended.

The air conditioner should be shut off if the room is to be kept unoccupied for more than 24 hours.

During hot days keep the house closed tightly, and use natural or forced ventilation at night when the air is cooler. Use the “ventilate” or “outside air” control on the room ac sparingly.

Do not block the system vents with furniture and other household.

Use the continuous air conditioner fan operation only when the resulting air movement is required to maintain comfortable conditions in the room.

Insulating your home for the summer is as good an idea as for winter. A well-insulated house will not let in hot humid air and will keep your house cooler.

Power / BTU’s of air conditioners is measured by COP known as Coefficient of Performance . The output of the ac is about three times that of the input.
Room Air Conditioners efficiency:

Efficiency of this system depends upon area, space and capacity of air conditioner. An air conditioner that is too big for an area will be less efficient and less effective than a smaller and required unit.Energy Efficient Room ac:

High-efficiency room air conditioners save money on your utility bills.
High-efficiency room air conditioners result in fewer environmentally harmful emissions.

On an average air conditioned home consumes more than 2000 kilowatt-hours of electricity per year for cooling, causing about 3,500 pounds of carbon dioxide and 31 pounds of sulfur dioxide to be emitted by the power plant. At average electricity prices costs about Rs.6000. A high-efficiency AC unit can reduce energy consumption (and environmental emissions) by 20% to 50%.About Air Conditioner Efficiency

Room ac use electric energy to pump heat out of your home. They distribute cooled air throughout your house and remove moisture form indoor air. EER is used to measure efficiency of air cooler. This is defined as the cooling output (in Btu per hour) divided by its energy input (Watts) at specified indoor and outdoor temperatures. Higher energy efficiency rating are better. The minimum eer should vary between 8 and 9, depending on the capacity and type of unit. For the best usage it should be 13.Tips for Lowering Your Room Air Conditioner’s Energy Usage

During winter or mild summer replace AC with fans even though fans cannot replace air conditioning, they can provide supplemental cooling. Substituting fans for air conditioners can reduce energy use by 60% or more.

Install a programmable thermostat unit with invertor ACs, if you do not have one. You can save as much as 10 to 15% on your cooling bill by simply turning your thermostat back 10 to 15 degrees for 8 hours. You can do this easily using it.

Set your thermostat as high as comfortably possible in the summer with higher energy efficiency ratio. The less difference between the indoor and outdoor temperatures will result in lowering your overall cooling bill.

Don’t set your Thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.

Room ac must be installed on a flat, even surface so that the inside drainage system and other mechanisms operate efficiently.

Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will make for a more comfortable home by removing more moisture from the air.

Using an interior fan in conjunction with your window air conditioner which has aluminum coil or copper coil to spread the cooled air more effectively through your home without greatly increasing electricity use.

Don’t place lamps or televisions near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.

It is important to install the unit in a shaded spot on the home’s north or east side because direct sunshine on the unit’s outdoor heat exchanger decreases efficiency. A unit operating in the shade uses as much as 10% less electricity than the same one operating under sunlight.

Room air conditioners should not be used in winter unless required.

Check your unit’s air filter once a month and clean or replace filters as necessary. Keeping the filter clean reduces load on compressor and can lower your air conditioner’s energy consumption by 5% to 15%.

Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.

Inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit’s metal case. Holes in the seal between the air conditioner and the window frame allow cool air to escape from your home.Tips for Buying a New Room AC.

There are three types of room air conditioners available:

window models which can be installed in most windows
casement models which are used in narrow, vertical windows, usually requiring the removal of a window panel for installation.
built-in models that are encased in a sleeve installed in the wall.

A small unit running for an extended period operates more efficiently and is more effective at cooling than a large unit that cycles on and off too frequently. Proper sizing is very important for efficient air conditioning. A bigger unit is not necessarily better because a unit that is too large will not cool an area uniformly.

When determining the appropriate size ac for your home important factors to consider are room height, local climate, shading, window size, etc. Also consider the dimensions of the area to be cooled. Based on size alone, an air conditioner generally needs 20 Btu for each square foot of living space.

Verify that your home’s electrical system can meet the unit’s power requirements. Room units operate on 220-volt circuits. The standard household receptacle is a connection for a 220-volt branch circuit. Large room units may require a dedicated circuit and special circuit depending on rating.

If you are mounting your air conditioner near the corner of a room, look for a unit with airflow in the desired direction for your room layout.
