High-Velocity Air Conditioner Vs. Mini Split

How Much Clearance Must Be Left Around Outdoor HVAC Unit?


Homes aged over 150 years often lack central air conditioning, necessitating considerations for duct insulation. For those averse to duct installations, alternatives like mini-split and high-velocity air conditioners come into play. This article delves into a comparative analysis of these two systems; High-Velocity Air Conditioner Vs. Mini Split, highlighting their differences and similarities.

Ductless Mini-Split Air Conditioners:


1. Efficiency: Minisplit systems boast highly efficient technology, swiftly converting high-voltage electricity with minimal energy consumption. A system with a SEER rating over 25 ensures significant energy savings.

2. Varied Zoning: Mini-splits allow users to create zones in their homes, tailoring temperature settings based on occupancy. This zoning flexibility enhances overall comfort and energy efficiency.

3. Noise Reduction: Operating quietly compared to traditional window and central air conditioners, minisplits provide a noise-free cooling experience.

4. No Duct Installation: The absence of ducts in mini-split systems eliminates the need for costly installations. The indoor unit installation is quick and straightforward, requiring minimal effort.


1. Filtration Capacity: While mini-split systems have air filters, their filtration capacity may not be the most robust. Users often resort to adding carbon inserts to enhance filtration.

2. Cost: Initial costs for mini-split systems are typically higher than high-velocity systems. However, long-term savings on electricity bills can offset this initial investment.

3. Multiple Units Required: To efficiently cool multiple rooms, each room usually requires a separate mini-split unit. This can impact the system’s aesthetic appeal and increase installation costs.

High-Velocity Air Conditioners:


1. Unobtrusive Placement: High-velocity units, often located in basements, have discreetly placed vents that are small and inconspicuous in walls and closets.

2. Single Unit Requirement: Unlike minisplits, high-velocity systems require only one unit for the entire house, reducing installation costs.

3. Fast Cooling: Known for quickly distributing air at high velocity, high-velocity units expedite the cooling process, eliminating the need for extended wait times.


1. Noise Levels: The forced air circulation through small vents may result in increased noise levels. Some brands are working on soundproofing technology, but noise remains a potential concern.

2. Physical Discomfort: The high-velocity air stream may cause physical discomfort when directed at occupants. Strategic vent placement is recommended to alleviate this issue.


Before choosing between a ductless minisplit and a high-velocity air conditioner, thorough consideration of factors such as current insulation, home square footage, layout, and occupancy is crucial. Additionally, understanding budget constraints and consulting with a licensed HVAC expert can help streamline the decision-making process and plan for a suitable installation.
