Temperature and humidity control are two main advantages of modulating HVAC systems, but these concepts are sometimes too abstract for homeowners during the HVAC system purchasing process.
It is important to demonstrate how temperatures and humidity can affect daily life.
While a fixed speed HVAC system can only run at full speed, a modulating system can have two or more speeds. In terms of temperature, this means a modulating system will provide consistent air conditioning that is commensurate with the need in the home, as opposed to fixed speed’s all or nothing method. A homeowner would notice this difference most in the rooms that receive the least airflow and leads to hot and cold spots. A fixed speed system can cause a homeowner to be both too hot and too cold. A modulating system can provide a longer lasting and less intense airflow, keeping your rooms at a more precise temperature and providing better comfort control while you are asleep. In modulating HVAC systems, more air is cycled through, which removes moisture and lowers indoor humidity. This saves energy and keeps your humidity level lower than 50 percent. A modulating system prevents harmful mold growth as well. It’s important to evaluate how important in home comfort and livability are. Purchasing a modulating HVAC system can provide tangible benefit to the way you live and sleep and for some people, can be priceless!
