For houses built around radiators

Ductless Mini-Splits in Belmont, MA

Quiet heating and cooling for rooms the old system never reached, placed with care and routed tidily along the outside of the house.

Comfort for Houses That Were Built Around Radiators

A great many older homes were designed around a boiler and a run of cast-iron radiators, which means there is no ductwork for central air and no easy way to add it. Ductless mini-splits solve that neatly. Outside sits a condenser; a pair of refrigerant lines passes through a hole no wider than a fist to one or more indoor heads, each with its own controls, so a bedroom, a home office or a whole floor can be heated and cooled on its own schedule. They also suit the rooms that have never behaved: the finished attic that roasts in August, the sunroom that is useless from December to March, the addition someone tacked onto the back in the eighties. For two-family owners, ductless heads let each unit run independently, which keeps tenants and owner-occupants from arguing over one thermostat. The quality of a ductless job lives in the details, so we spend time on placement. A wall head too close to a corner leaves half the room stale; a line set dropped straight down the front of the house can spoil the look of a colonial. We walk through each location with you, agree on where every line will travel and put the plan in writing before anything is ordered. If a Belmont Light rebate is part of the plan, the equipment is chosen with that program's rules in mind.

What a Ductless Project Includes

From a single attic head to a full house of them, the job runs through these steps.

  • Capacity per room

    Each head matched to the room it serves, so small rooms are not overpowered and large ones are not left short.

  • Head style choice

    Wall, floor-console or ceiling cassette units chosen for the room's layout and furniture.

  • Placement walk-through

    Every indoor and outdoor location agreed with you on site before the plan is written.

  • Tidy exterior routing

    Line sets run in covers along discreet paths that suit the look of the house.

  • Condensate handled

    Drain lines planned so water leaves the head cleanly, through gravity or a quiet pump.

  • Separate controls

    Remotes or thermostats for each zone, so rooms and units can run on their own settings.

  • Startup and walkthrough

    Testing every head, then showing you the modes, schedules and filter cleaning.

How a Ductless Job Moves Along

  1. Pick the rooms

    On the phone we talk about which spaces need help and who lives where. During the visit we measure those rooms and look at outside wall space.

  2. Agree on the layout

    Head locations, outdoor units and line-set routes go into a written proposal with the price and any rebate details.

  3. Install and test

    The crew mounts the units, runs and covers the lines and tests every head, then stays until each remote makes sense to you.

Why Owners Trust Us With Ductless Work

  • Placement over speed

    We take the extra time to put each head where it will actually reach the whole room.

  • Houses kept handsome

    Line sets are routed with the street view in mind, not just the shortest path.

  • Units kept independent

    Two-families get a separate setup per unit, so households stay comfortable on their own terms.

  • Heads sized per room
  • Locations agreed first
  • Covered line sets
  • Zone controls
