What Are The Causes And Consequences Of Mold Due To AC?

causes of mold

Mold is a typical component of both indoor and outdoor environments. Mold rarely causes issues until it grows indoors in wet regions if inhabitants or tenants are allergic to it. However, Mold replicates by producing spores, which are dispersed by the water, the air, and other living things like dogs. Although some people are vulnerable to these spores, which are rather common in houses, even in modest concentrations, the risk increases when they find conditions where they may grow into moldy regions.

Dubai has extreme summer heat, with 90% humidity on average. The moisture and oxygen content is the primary factor in the development of mold. It’s possible that water leaks or moisture from humid inside air are to blame for the dampness in the walls.

Causes of Mold

One of the reasons for disagreements between the local rental company and its renters is mold growth. Mold contamination inside can result in nasal congestion, coughing, headaches, eye burning, shortness of breath, and headaches. According to studies, some children’s asthma may also be caused by mold infection. Others who come into touch with mold report experiencing skin rashes and discomfort.

Particularly air conditioning units may provide a lot of moisture for the growth of mold. This could occur due to leakage or even moisture on the evaporator coil. This problem is worsened by the fact that the mold spores are then dispersed around your house by the AC. Some of the causes are:

  • Leaking of cold AC supplies air into an unconditioned roof or crawl space.
  • an unsecured roof or crawl area where an open supply or return air duct from the structure has penetrated,
  • Filters that are improperly installed, access doors to the AC cabinet, or open duct connections at the AC unit.
  • Blocked or incorrectly fitted drainage plumbing on the condensation drain pans for AC unit cooling coils.
  • Insulated refrigerant lines that are not adequately secured or badly maintained.

Mold growth signals in air conditioners

Although mold within air conditioners isn’t usually immediately apparent, some symptoms can indicate it. Residents of the home typically experience health challenges as a result, such as respiratory issues. It could be time to contact a mold expert if someone living in the home has recently seen changes in their health without a clear cause.

A perceptible musty odor around the air vents in your home that gets stronger when the system is working is one more warning flag to look out for. Additionally, look for mold growth near drip pans, evaporator coils, and vents.

Cleaning and checking for leaks monthly will help you avoid this problem. Additionally, keep in mind that leaving your air conditioner on might increase humidity, which in turn promotes the growth of mold.

Excess moisture is caused by more than simply air conditioners. It’s also crucial to ensure sure holes around windows and other entry or exit points are sealed, given Dubai’s humid environment and the variations in temperature between indoors and outdoors. This includes keeping front doors closed in villas since condensation will undoubtedly form when chilly air from within meets warm, humid air from the outside.

Four components should be part of the cleaning procedure:

  • Removal of the fungus’ source may be contaminated dust, debris, or other unwanted materials.
  • The identification and correction of the mold’s underlying cause.
  • Control of the pollutant area to stop the fungus from transmitting.
  • Treatment of the affected areas with an antibacterial agent.

At last

Moisture, heat, and nutrition are necessary for the growth of mold spores. It’s imperative to act if you see visible mold growth or a musty stench. Ignoring the issue might endanger your health severely in the future. Filter replacement regularly, yearly HVAC maintenance, and maintaining proper humidity levels are all crucial steps in lowering the likelihood of mold formation in your house.
