Understanding the Basics of Your⁣ AC’s Evaporator Coil

The ⁣core element of your cooling system is the evaporator coil. Composed mainly of copper tubes, the main function of the ⁤evaporator coil is to absorb‍ the ⁢heat from your indoor air. This ​is accomplished as ‌the refrigerant flowing in these coils evaporates under the effect of a heat source, hence the name ‘evaporator’. As ⁣the warm ‌vapor cools down, the dehumidified air is then‍ blown back into ‌your living space to maintain a comfortable temperature.

The necessary environment for mold growth includes ‌a moisture source, warmth, darkness, and ‌an organic ‘food’ source. Unfortunately, such conditions are ideal within your AC’s evaporator ⁣coil, which often comes in contact ​with⁢ dust and ⁤organic matter present in your indoor air. As part⁤ of your AC’s dehumidification ​process, water droplets ⁣collect on the evaporator⁢ coil. When combined with dirt particles and warmer ambient temperature, these moisture areas can become breeding grounds for mold.

Common signs of mold growth in your AC’s evaporator coil:
– Musty odour whenever AC is running
– Increased ⁣respiratory allergies
– Visible mold spots
– Unusual high energy bills

When it comes to mold growth prevention or ‌mold removal, regular maintenance plays a vital role. It includes⁤ checking on ⁢your evaporator coil on a routine basis for any signs of mold and other possible damages. It is also significant to ensure that your indoor humidity levels are controlled to decrease the‌ chances of‍ mold growth.
