One of the main advantages of a high velocity heating plus cooling plan is that it accommodates unquestionably narrow spaces. I have an older, historical beach home plus was unwilling to compromise integrity by chopping down the original walls. I was also hoping to avoid the mess of of installing big, bulky HVAC duct. A high velocity plan uses small, flexible air ducts that are truly threaded through the walls plus ceiling panels without the need to make big holes. The vents are also unquestionably small in diameter plus incorporate into any room without destroying aesthetics. In the past, high velocity systems were severely noisy. Although air is pushed through the ducts at an accelerated speed, new high velocity systems are designed to provide whisper-quiet performance. There are none of the mechanical fan noises that are often a concern with ductless systems. In the area where I live, there’s super high humidity levels during the summer. A benefit of high velocity a/c is that it is appealingly effective at removing humidity from the air. It defends against moisture-related complications, such as mold, mildew plus that sticky feeling. Because high velocity heating plus cooling systems use a third of the space necessary for a conventional system, there is less surface area, which means less leakage! Drafts plus uneven temperatures are a frequent complaint with traditional central cooling units. With high velocity units, these complications are avoided. The plan maintains ideal temperature by using suction to create a gentle stream of circulating air, created unquestionably even comfort; For retrofit into an older home, a high velocity plan provides efficient year round temperature control.
