A Residential Fan Coil Unit (RFCU) is a heating and cooling system found in many homes. It’s one of the most efficient and cost-effective ways to keep your home comfortable year round. RFCUs work by circulating air through a series of coils that are heated or cooled, depending on the season. They provide reliable and consistent temperature control by leveraging the latest technology and a variety of features such as built-in fans and timers. RFCUs are great for saving money on energy bills and keeping your family comfortable – no matter what the weather brings!
