Ductless mini-splits for houses that were never built for ducts
Most homes around Lowell went up before central air was invented. Mini-splits heat and cool them anyway — room by room, no ductwork, no gut renovation.
Built for this housing stock
Lowell houses are our home turf.
This city runs on triple-deckers, mill-era rowhouses, and colonials with steam radiators and horsehair plaster. Beautiful buildings, zero ductwork. For a century the only cooling option was a window unit in every room, dripping onto the sidewalk from June to September.
A ductless system changes the math. A quiet indoor unit mounts high on the wall in each space you want conditioned, connected to an outdoor unit through a hole about the size of a baseball. The same equipment that cools in July is a cold-climate heat pump in January — so a house heated by an aging boiler can add real heating capacity and cooling in one project, without touching the radiators.
- Triple-deckers and two-families — a zone per floor, separate control for each unit.
- Boiler and radiator homes — keep the radiators, add cooling and backup heat.
- Additions, attic rooms, and converted porches the furnace never reached.
- That one bedroom that's always freezing — a single-zone unit fixes exactly that.
Sizing it
One zone or the whole house
Single-zone
One outdoor unit, one indoor unit, one problem solved. This is the right tool for an addition, a finished attic, a home office over the garage, or the bedroom that never keeps up. It's a one-day install in most cases.
Multi-zone
One outdoor unit feeding several indoor heads, or several separate systems — which is better depends on the building, and we'll show you the trade-offs in the quote. Whole-house ductless is how a lot of Lowell homes are going fully off oil.More on whole-home heat pumps.
The details we sweat
A clean install on an old house takes care.
- Head placement chosen for airflow and looks — not just wherever the line run is easiest.
- Line-set covers routed straight and painted-ready, so the outside of your house doesn't look like an afterthought.
- Condensate drains that actually pitch downhill. It sounds obvious. It gets skipped.
- Careful penetrations through old clapboard, brick, and plaster — sealed against weather and mice.
- Cold-climate rated equipment only. A bargain unit that quits at 10°F is no bargain in Massachusetts.
