High Velocity Explained

A High Velocity HVAC system uses small, flexible ducts (piping) to deliver hot and cold air at high-speed rates. The 2" circular ducts cause the air to move very quickly from your furnace / air conditioner through your home. This results in better airflow with less energy usage. The superior sealing of the small ducts cuts down on air loss by roughly 90%, also resulting in energy efficiency. This type of system eliminates dust build-up in ducts (due to the fast airflow) and reduces humidity by up to 30% compared to traditional HVAC systems.



When should I replace my High Velocity system instead of repairing it?

  • Expired Warranty: If your system is older, it may no longer be under warranty. Also, many replacement parts are slow to come in (due to supply chain issues or extreme weather conditions) or are no longer available.
    Our technicians will diagnose, check parts availability, and explain both options.
  • Expensive Repairs: If your system requires repairs that exceed 1/3 of the price of a replacement, we recommend replacement over repair. Other parts (not associated with performed repairs) often break shortly after repair, so those parts would result in additional expenses as well.
  • Save Money: If you can save money on utilities by buying a new system, consider it. Newer or higher rated equipment can save you money on energy consumption, perhaps with better heating performance. Those savings can pay for your new system over the life of the system.
