In this short video, Derek Cole outlines three key indicators that an HVAC system requires professional service. First, he notes that if it has been more than six months since the last service, the unit should be inspected, as HVAC systems benefit from biannual maintenance. Second, he warns that any unusual or unpleasant odors emanating from the vents signal a potential problem that needs a technician’s attention. Third, he points out that slower heating or cooling performance can stem from issues such as low refrigerant or a faulty fan, and should prompt a service call. Throughout, he emphasizes the importance of timely maintenance to prevent larger problems and ensure the system operates efficiently across seasons.
