FAQs

Many New England homes were built before central air existed, with plaster walls that leave little room for ductwork. High velocity air conditioning uses small, flexible tubes that fit where standard ducts don’t. Ace Hardware Home Services installs, repairs, and maintains these systems for older homes across the greater Boston area.

Overview

What Is High-Velocity Air Conditioning?

A high velocity system is central air conditioning that uses 2-inch-wide insulated tubes in place of large rectangular ductwork. It’s designed for older homes that lack the wall cavities normally required to hide air ducts.

The system moves air through the tubes at high speed to compensate for carrying less air than standard ductwork. This gives you whole-home cooling like conventional central air, but with small, manageable tubes instead of ductwork.

Why High Velocity Systems Work Well in Older Boston Homes

Century-old triple-deckers, Victorians, and brownstones were built with radiator heating, so few have the ductwork needed for forced-air systems. In most cases, high velocity air conditioning is the best way to enjoy central air for older homes in Boston.

Here’s why:

• Minimal wall and ceiling disruption: Flexible tubing threads through existing wall cavities, closets, and floor joists. Installers usually need only small access holes.
• Preservation of original trim and plaster: Small duct AC needs no bulky soffits to hide large air ducts, so crown molding and plaster ceilings stay intact.
• Even cooling in every room: One central system cools your whole house, just like conventional central air.
• Lower humidity: Manufacturer Unico reports that its systems remove up to 30% more humidity than regular central air conditioners. Drier air makes humid Boston summers more comfortable.
• Quiet operation: Sound-dampening tubing at each outlet reduces the noise of blowing air.
• Hidden equipment: The air handler is installed in the attic, basement, or utility closet, so nothing hangs on your walls or blocks your windows.

Ductless

High Velocity vs. Ductless Systems

High velocity AC isn’t the only option for air conditioning in older Boston homes. Ductless AC is another viable choice. This system includes one or more wall-mounted air handlers connected to a single outdoor condensing unit. Each air handler has its own thermostat and remote for room-by-room temperature control.

Ductless systems work well for additions, finished basements, and rooms that run hotter than the rest of the house. However, if you’re concerned about keeping historic details untouched, you may prefer the more discreet nature of high velocity AC.

Ace Hardware Home Services installs both options. We’re happy to walk you through how each might fit your layout and budget.

Our High Velocity AC Services

Ace Hardware Home Services can take care of your high velocity system for throughout its whole life. Our services include:

• Installation: We size the system, map tube routes, and discreetly place outlets. We finish with a final walkthrough to make sure you know how to use your new system.
• Repair: Our technicians repair SpacePak and Unico systems in Boston and other high velocity AC brands. Weak airflow, warm rooms, and water around the air handler are common reasons to call.
• Maintenance: We recommend yearly tune-ups to improve efficiency and lower the risk of breakdowns.

Did you know you can pair a high velocity air handler with an outdoor heat pump? This lets you use the same tubes for central cooling in the summer and heating in the winter.

Integrating high velocity AC with a heat pump makes sense if you want to retire an old boiler or heat rooms without their own radiators. We’ll help you decide if this setup is right for your home and show you which heat pumps qualify for rebates.

FAQs
High-Velocity AC Service FAQs

Can I get central air without ductwork?

Expand content
Yes. A high velocity system delivers central air through 2-inch flexible tubes that fit inside existing walls. Ductless mini-splits are another option that provides room-by-room air conditioning with no ductwork at all.

How much wall damage does a high velocity installation cause?

Expand content
Installation usually causes very little damage. Technicians route tubing through existing cavities and closets, so most work involves small access holes and 5-inch outlet openings. We’ll explain where patching may be needed before work begins.

Is high velocity AC better than a ductless mini-split?

Expand content
Neither system is inherently better. High velocity works well for whole-house cooling with hidden outlets, while ductless AC offers room-by-room control. Our team will help you decide what fits your needs best.

Do you service existing high velocity systems?

Yes, if you already have a high velocity air conditioning system, our team can provide repairs and routine maintenance.
