Airflow Of A Evaporator Coil In A Attic Hvac Unit

An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.

Airflow of a evaporator coil in a attic hvac unit.

In fact the evaporator coil often fails due to issues with the condenser coil. So if your evaporator coil has sprung a leak and your unit uses r 22 it could get very expensive to replace the coil and then recharge your unit with more r 22. It s critical to have your evaporator coil inspected annually and most dyi ers are more than capable of cleaning the external surfaces facing the duct airflow. R 22 is so expensive in fact that most hvac professionals would advise replacing the entire unit not just the evaporator coil if you have a refrigerant leak anywhere in the system.

The external surfaces of the evaporator coil that face the airflow in the duct are accessible and cleaning is generally within the skill level of most do it yourselfers. As the condenser fan spins it attempts to draw air across the condenser coil and through to the evaporator coil. Attic hvac systems save space. Well mainly it s a way to save space.

Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. The evaporator coil can be a magnet for dust debris and other contaminants this is because it is installed within the airstream of your hvac system. Your evaporator coil is an a shaped web of copper coils that sits inside your indoor ac unit. The condenser coil on the outside unit is just as important as the evaporator coil on the indoor unit.

However if dust or dirt contamination is so extensive that the inside coil surfaces are affected too schedule a more extensive heavy duty cleaning procedure with your hvac.
