As this blog is being written, the humidity here in Warwick, Rhode Island, is 90%. According to research by Building Science Corporation, an elevated relative humidity of 70% or higher can lead to structural problems with mold, corrosion, decay, and other moisture-related surface deterioration. If you also live in a region with high levels of humidity, it is important to understand the effects these conditions have on your HVAC system and what you can do to prevent them.
The Ideal Humidity Level
For health and comfort, the humidity in an indoor space should be between 30% and 50%. You can use a hygrometer to gauge the moisture levels in your home or business and use that information to adjust accordingly. When measuring the humidity throughout your home, it is also helpful to know where that moisture is coming from.
Why Humidity Levels Are Important
On top of general issues that arise in buildings with high humidity levels, there are problems that can directly affect your HVAC system. There are some preventative steps you can take to avoid such issues from arising:
Clogged Air Filters: Air filters collect particles such as dust, debris, and other pollutants. When the environment is more humid, these particles can stick together and block the filtration system more quickly. When this happens, it decreases the effectiveness of your HVAC system, raises utility bills, and reduces air quality. To remedy this, change your filter more frequently. The recommended frequency of changing air filters is dependent upon the type of filter you have. We recommend you check the filter manufacturer’s recommendations or ask your HVAC technician.
Condensate Drainage Issues: Too much condensation can cause the drainage system to become clogged, which in turn can cause your unit to break down due to a backlog of water. You must have your system regularly inspected to ensure that this doesn’t occur so your system can maintain peak efficiency and avoid water damage, as well as mold growth.
Frozen Evaporator Coils: If too much moisture restricts airflow, your evaporator coils won’t be able to absorb heat which can cause damage to the compressor. Call an HVAC technician to clean your frozen coils and inspect your system if you notice that warm air is blowing out of your air conditioner.
Living in humid climates comes with unique challenges homeowners must take into consideration. We hope this blog has helped identify some of those concerns when it comes to your HVAC systems.
