The more options you get to choose from, even more difficult it becomes to choose the best among them. It is very important to know the technical terms, what to look into deeper and what to focus lesser.

Like any other system air conditioning system has got its own glossary of terminologies. If you are planning to buy an ac it is very important to get familiar with day to day words being used.

Consequently, you will be able to compare two air conditioners. You will be able to to converse easily with mechanics during the maintenance of your air conditioner.

We are listing it below. Brush your knowledge.

1. Split System

The air conditioner unit is split into two units. One unit is called Indoor Unit and positioned in the room. The Second unit is called the Outdoor Unit and fitted outside the room.

These types of air conditioners are very popular for home use. Because they produce less noise and consume less energy.

The split air conditioners are easy to maintain and easily portable. Their fitment is also easier and doesn’t need ductwork.

2. Inverter Technology

An ac with inverter technology controls the speed of its compressor motor to increase or decrease the room temperature. In other words, it provides a variable speed compressor motor.

The compressor needs not to switch Off and On frequently to adjust the room temperature. Hence, the ac consumes lesser energy and you save money.

3. Thermostat

It actually a sensor that senses the temperature in the room. Thereafter, as per this temperature, the air conditioner decides whether to increase or decrease the temperature.

Accordingly, the compressor will adjust speed. It increases the speed for faster cooling and decreases the speed for slower cooling.

4. Refrigerant

Refrigerant is a compound found in a fluid or gaseous state. Most of the time it is converted to gas and then back to liquid.

The refrigerant collects heat from indoor coil and releases it at the outdoor coil. Alongwith compressor it plays crucial role in reducing the air temperature.

The most common refrigerant includes R-134A, R-407C, R-404A, R-410A, R-32, R-22 etc.

5. R-32 And R-410A

R-32 and R-410 both are non-ozone depleting refrigerants. R-32 is the successor to R-410. It causes less global warming than R-410. Energy-efficient air conditioners use R-32 gas.

6. EER (Energy Efficiency Ratio)

It is a measurement of the cooling output of an air conditioner divided by its energy usage. EER is calculated under specific test conditions that represent peak load. Higher the number, more energy-efficient is the air conditioner.

7. SEER (Seasonal Energy Efficiency Ratio)

SEER measures the efficiency of cooling equipment, calculated based on a seasonal average instead of at specific laboratory conditions. A higher the SEER rating means the unit is more energy efficient.

8. HSPF (Heating Seasonal Performance Factor)

HSPF measures the efficiency of the system’s heat pump. Again, a higher number means a more efficient unit.
