Your air conditioner’s coils are key players in cooling your Cincinnati home or business. When they are clean and clear of debris, they can easily absorb heat from inside your home and cast it off outside – when your coils are dirty and caked with grime, they will not function as expected. Below, we’ll tell you more about how your coils work and why it’s important they be kept clean.
How AC coils work
Your air conditioning system has two sets of coils: the indoor evaporator coils and the outdoor condenser coils. Refrigerant flows through the system, from the expansion valve which lowers its pressure, to the evaporator coil. As it moves through the evaporator coil, the refrigerant becomes a gas and absorbs excess heat from the air passing over the coil. Next, the refrigerant is pressurized in the compressor and moves to the condenser coil. The condenser coil transforms the heated refrigerant gas into liquid, allowing it to release heat into the surrounding outdoor air.
Air conditioners cool homes and businesses through heat exchange, rather than creating chilled air. The surface area of each coil is utilized to absorb and release heat. Clean coils allow heat exchange to occur uninhibited, whereas the available surface area of a dirty coil is restricted, so heat exchange cannot occur as effectively or efficiently.
Dirty coil problems
When your system’s coils are dirty, the air conditioner won’t be able to conduct heat exchange properly.
• The system is forced to overwork to exchange heat, consuming excess energy which lowers system efficiency. This places more stress on system components, which can cause breakdowns.
• When the heat exchange process is hindered, your air conditioner may not be able to keep your home or business at the desired temperature.
Keeping coils clean
To prevent dirt and debris from impacting the heat exchange process, your air conditioner coils should be professionally cleaned on a yearly basis. You can help prevent debris and grime from building up on your outdoor condenser coil by trimming away nearby trees, shrubs, and other vegetation.
