Key points to consider before buying an Ac
The total volume required to cool a room depends on the size of that room. For instance, a 1ton AC for a compact room of upto 120 sq.ft. is more than enough as the heat load is manageable
However, in a average medium-sized room, a 1-ton AC is likely to be overloaded
Noise is an important point which needs to be considered when designing HVAC equipment because of its disturbing factor.
Air conditioner noise is controllable and can be minimized with the use of insulator, rubber and other noise absorbing materials.
Good equipment design and layout plays an important factor in the air conditioner noise emitted by the machine.
3.Temperature / weather
The weather temperature is also critical factor in determining the type of AC you will need for your space. If you live in a place with hot summers, then you may require a 1.5 AC even for average sized rooms .
4.Number of people
Another important factor to consider before purchasing an air conditioner unit the number of people in a space .
This means that if a room is filled with lots of people then you need a stronger unit to cool the space.
What is an Air conditioner
It is a system which removes heat from the space or room cools down the entire room at desired temperature. The heat is extracted outside the room by the help of the unit. The cool air is transmitted through the machine extracting the outer air with the help of the compressor through proper ventilation.
How does it works
- Step 1: Warm air is absorbed by the evaporator coil. The air inside your room is extracted through a vent and blows over the cold evaporator coil.
- Step 2: Compressor raises the refrigerant temperature.of the unit
- Step 3: Heat is transmitted outside of the unit
- Step 4: The air in the unit gets cold and passes down the unit into the room.

Condenser Coil Aluminum Vs Copper
Transfer of heat
The main purpose of the coil is of transferring heat Copper has the higher capacity of transferring heat than that of aluminium. Therefore copper coil is better when it comes to transfer heat .
Copper is more costly than aluminium.. Therefore, an AC having copper coils is more expensive as compared to aluminium which can lead to more expensive AC. Hence, aluminium coils are cheaper better when it comes in comparison the cost factor.
Copper is more long lasting and durable than aluminium coils.. When aluminium coils get damaged you have to replace it.. It is not the same case with the copper coils. You can again repair and reuse Them if it gets damaged. Hence, copper is more long lasting and durable than aluminium coil
The maintenance of coil depends on the durability and has direct effect on it . As copper is more long lasting , the maintenance of its not much needed. Aluminium Coils on the other hand need more maintain and it can be expensive. Therefore, copper is more opted that in comparison of aluminium coil in terms of maintenance.
