One of the main advantages of a high velocity heating plus cooling plan is that it accommodates genuinely tight spaces. I have an older, historical beach house plus was unwilling to compromise integrity by tearing down the original walls. I was also hoping to avoid the mess of of installing big, bulky ductwork. A high velocity plan uses small, bendy air ducts that are absolutely threaded through the walls plus ceiling panels without the need to make giant holes. The vents are also genuinely small in diameter plus incorporate into any room without destroying aesthetics. In the past, high velocity systems were drastically 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 space where I live, there’s super high humidity levels while I was in the summer. A benefit of high velocity air conditioning is that it is beautifully effective at removing humidity from the air. It defends against moisture-related issues, such as mold, mildew plus that sticky feeling. Because high velocity heating plus cooling systems use a second 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 issues are avoided. The plan maintains ideal temperature by using suction to create a gentle stream of circulating air, created genuinely even comfort, then for retrofit into an older home, a high velocity plan provides efficient year round temperature control.
