How does AC help in Heat Wave Conditions?

The air conditioner draws air into the ducts through the vents. This air is used to cool the gas in the evaporator and is cooled heat is removed from the air. A duct then sends the air back to your home. This process continues until the indoor air in your home or business comes to the desired level of temperature.

Why does AC require regular cleaning and maintenance?

The filter, coil, and fin of an AC need regular maintenance for the smooth and efficient functioning of an AC unit throughout its years of service. If you neglect the necessary maintenance of an AC, it would lead to a steady decline in air conditioning performance while electricity consumption steadily increases.

What does Evaporator Coil do?

The evaporator coil is a part of the AC system that is instrumental in absorbing the heat from the air inside your house. It is either connected to your furnace or attached to the air handler of the interior of your house. It works with a condenser coil completing the heat exchange process and producing cool air. The evaporator coil is always loaded with evaporated refrigerant which the compressor pushes into the metering device in the form of liquid and then into the evaporator. The air that is pushed into the coil from the blower fan rotates over the coil where the refrigerant in the evaporator absorbs the heat.

Cleaning and MaintainingEvaporator Coil

Cleanliness and maintenance of the evaporator coil are very important to maintain the efficiency of the system. Dirty coils can increase your air conditioner’s energy consumption by up to 30%. Poor maintenance of the coil can also cause other problems in the system, such as poor cooling performance due to poor heat transfer, frozen coils, and overheating of the compressor. Replacing your air filter at least once a month will keep your evaporator coil clean and improve its performance. If the filter is too clogged, dirt and dust will stick to the evaporator coil instead of the air filter. For this, you should take the help of the best AC service in Chennai.
