Excessive humidity can cause mould and algae to grow in ductwork, impacting air quality

High humidity can cause a range of issues for air conditioning systems, and it can be challenging to define and manage. HVAC experts recommend keeping indoor humidity levels below 60% for optimal comfort and AC efficiency. However, maintaining this level can be difficult due to changing weather conditions. High humidity can make a room feel warmer, leading to increased AC usage and higher energy costs. This puts additional stress on the AC unit, resulting in more frequent breakdowns and reduced lifespan.

Excessive humidity can also negatively impact the cooling efficiency of an AC system. The AC unit has to work harder to achieve the desired temperature, often leading to inconsistent cooling across different areas. This issue is more prevalent in older AC models that lack integrated dehumidifiers, which are common in newer units. Single-speed AC units that can only run at one speed may also struggle to remove humidity effectively.

Furthermore, high humidity can create an environment conducive to the growth of mould and algae within the ductwork. This growth can significantly deteriorate indoor air quality, potentially causing allergies, respiratory issues, and exacerbating asthma symptoms. To address these issues, homeowners can consider installing a dehumidifier to maintain healthy moisture levels and improve AC efficiency. Regular maintenance of the dehumidifier is crucial, including cleaning the air filter monthly and checking the reservoir.

Older air conditioners may lack dehumidifiers, reducing their effectiveness in humid conditions

Air conditioners are designed to cool the air and, as a result, reduce some moisture in the air. However, older air conditioners may lack the integrated dehumidifiers that are common in newer units. Traditional models of air conditioners may not be able to properly dehumidify the air, especially at colder temperatures.

Air conditioners with only one speed can have problems with HVAC humidity control. When the unit can only run at one speed, it runs at full blast until the air reaches the set temperature, and then turns off. This means that the unit does not run consistently enough to remove humidity.

The coil on a dehumidifier is significantly colder than the coil on a typical air conditioner. When the air passes over the coil, water below the coil temperature's dew point condenses onto the coil and drips off into the drain pan. As a result, dehumidifiers can remove a high amount of moisture at a given time. In contrast, the volume of moisture removed by an air conditioner is not as great.

High humidity can make temperatures feel warmer than they are, leading to increased use of air conditioning and higher electricity bills. It can also create an environment conducive to the growth of mould and algae within the ductwork, which can cause health problems such as allergies and respiratory issues.

In some cases, using both a dehumidifier and an air conditioner can provide a more balanced approach to temperature and humidity control.
