Installation
An installation-first service page for homeowners who want better sizing, clearer planning, cleaner payment expectations, and a direct path into scheduling.
Installation Focus
Installation should feel like a planning page, not just a product page: explain why sizing matters, show why oversized equipment causes problems, and make it easy to schedule service.
What right-sized means
Right-sizing means matching the system to the real load of the home instead of overshooting for the sake of speed or sales pressure. Installation is about planning discipline, not just equipment swapping.
That means talking clearly about sizing, load calculations, walkthroughs, and why long-term comfort depends on choosing equipment that fits the house correctly.

Common scope
High velocity HVAC installation in Greater Boston. 2-inch flexible tubing routes through existing wall cavities with no soffits or major wall demolition. Ideal for Cambridge and Boston historic homes.
We own a two-family in Cambridge. When we renovated the second and third floor unit, we needed to add air conditioning. Traditional ductwork meant soffits: dropping the ceilings by six to eight inches in a building that already had lower ceilings than we wanted. Mini splits were an option, but we did not want wall-mounted units compromising an interior design we had worked to get right. We chose a Unico high velocity system. Two-inch flexible tubing routed through existing wall cavities and floor joist bays during the renovation. Small five-inch round ceiling outlets that blend into the architecture. No soffits. No visible wall units. Full central air conditioning on two floors.

Installation FAQs
A high velocity system uses 2-inch flexible tubing instead of traditional 6-8 inch rigid ductwork. The tubing routes through existing wall cavities, floor joists, and ceiling spaces without soffits or major wall demolition.
617 HVAC high velocity system installation in the Boston area typically ranges from $12,000 to $20,000+, depending on home size, system complexity, and routing requirements.
It depends on the home and priorities. High velocity provides central air with no visible wall units and small outlets that blend into the architecture. Mini splits are less expensive but require wall-mounted indoor units in each zone.
Yes. High velocity systems can be configured for heating, cooling, or both. Combined with a heat pump air handler, the system provides year-round climate control through the same tubing network.
Yes, but mid-renovation installation is usually cleaner. We assess routing options and tell you what access is required before starting.
