Can you Oversize an evaporator coil?

If you oversize the evaporator coil a little, the air will spend more time in the vicinity of the coil, giving it more opportunity to transfer heat to the coil. You'll get both additional sensible and latent heat transfer (more capacity overall).

Regarding this, what happens if your AC is oversized?

The thing that wears equipment out is starting up and shutting down. The more it happens, the shorter the life of the equipment. When an air conditioner is oversized, it starts up and shuts down a lot more because it runs for only a short time to meet the thermostat setpoint.

Additionally, how do you know if the evaporator coil is bad? If the airflow feels weak or doesn't turn on right away, you might have a refrigerant leak. Other signs include warm air coming through the vents, hissing noises from the outdoor A/C unit, frozen evaporator coils on the outdoor unit, and unpleasant odors when you turn on the heating or cooling system.

In this way, why condenser is bigger than evaporator?

For example, an evaporator coil that is smaller than the condenser coils might, in some cases, provide better dehumidification but it can't cool the home as well. On the other hand, an evaporator coil that's larger than the condenser coils will cool the home well but will remove little to no moisture from the air.

How do you fix an oversized air conditioner?

  3. Replace the air conditioner.
