Considering this, how often should evaporator coils be cleaned?

To minimize energy usage and reduce utility costs, the A/C coils should be cleaned at least once a year. It is estimated that dirty evaporator and condenser coils can increase the energy usage of your air conditioning system by over 30 percent.

Also, what does a dirty evaporator coil do? Because it isn't absorbing enough heat, the refrigerant running through a dirty evaporator coil doesn't warm up as much as it should. This very cold refrigerant causes water vapor in your air to freeze rather than condense into a liquid. Eventually, the whole evaporator coil can frost over.

Keeping this in consideration, how much does it cost to clean an evaporator coil?

Evaporator coil cleaning costs $200 to $400. It costs more just because it's tough to access. You'll find it housed inside the air handler near your furnace (or inside your ductwork if you only have AC).

How do I access my evaporator coil?
