One of the first things to consider when choosing an HVAC system for high humidity is the size and capacity of the unit. It’s crucial to select a system that is properly sized for your space in order to effectively control humidity levels. An undersized unit may struggle to remove excess moisture, in the course of an oversized unit may cool the space too quickly, resulting in inadequate dehumidification. Consult with a professional to determine the appropriate size and capacity for your specific needs.
2. Energy efficiency ratings to look for
Another important aspect to consider is the energy efficiency of the HVAC system. Look for units that have high SEER (Seasonal Energy Efficiency Ratio) ratings, as these indicate better energy efficiency. Higher SEER ratings mean that the system can provide the same cooling or dehumidification output whilst consuming less energy. This not only helps to reduce your environmental impact but also saves you money on your energy bills.
Additionally, pay attention to the EER (Energy Efficiency Ratio) ratings, which specifically measure the cooling efficiency of the system at a constant outdoor temperature. A higher EER rating indicates better performance in high humidity conditions, ensuring that the system can effectively remove moisture from the air.
Consider models that are ENERGY STAR certified, as they meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. These units not only provide superior performance but also come with additional features such as variable-speed compressors or smart thermostats, further enhancing their efficiency and humidity control capabilities.
