If your mini split is low on Freon (also known as refrigerant), you might notice several signs. These include a decrease in cooling efficiency, longer system run times, ice formation on the refrigerant lines, or a hissing noise from the unit. However, detecting a Freon leak requires a professional’s expertise. At Carl J. Wendler Heating & Cooling, we offer mini split inspections to identify and rectify such issues, ensuring your system continues to serve you effectively.
