Home / Services / Ductless Mini-Split Installation
Astello puts ductless mini-splits into old Capital Region homes that were never built for ductwork — 1920s colonials, brownstones, farmhouses, even buildings mid-renovation. No tearing open walls, no window units. Each indoor head runs on its own, so every room gets the temperature it actually needs, and the cold-climate models heat all winter and cool all summer. We size it off the real house, run it clean, and file your NY Clean Heat rebate paperwork.

NY Clean Heat rebate paperwork handled
Most older homes around here run on radiators or steam heat, with no ductwork — and the walls won’t take it. Balloon framing, solid brick, knob-and-tube in the cavities: there’s nowhere to run a duct without opening the place up. A mini-split skips all of that. We drill one 3-inch hole per line set, and the indoor head ties to an outdoor condenser through copper refrigerant lines, a drain, and a communication wire — that’s the whole footprint.
What people worry about is how it looks. On a 1925 house in Ballston Spa we ran eight zones off two condensers and tucked the line sets into paintable covers matched to the siding — from the street you’d barely spot them. Done right, the plaster, the trim, and the brick stay exactly as they were.

Real Astello installs
A 1925 two-story on a 6-acre waterfront lot — original plaster and wood-frame walls, light on insulation. We ran a Manual J, sized it for the coldest day, and put in eight zones off two condensers, one on each side of the house. The line sets disappear into paintable covers matched to the siding.
We even added a ceiling cassette in the basement to keep the pipes from freezing in winter and pull moisture in summer. The oil system came out, they got the maximum rebate — paperwork handled end to end — and the house feels fresh: better air, and worth more than it was.
A 3-story building being converted to apartments — the kind of city job where a clumsy install ruins the look. Every unit got its own concealed 4-way ceiling cassette on a hyper-heat system, with the condensers up on the roof. The line-set runs and wall penetrations were the hard part, and we hid all of it — the building keeps its historic face, and every apartment controls its own heat and cooling.
Heat rises, so old houses cook upstairs in summer and leave back rooms cold in winter. Put a head in each space and every room runs on its own setpoint — you’re not blasting the whole house to fix one bedroom.
We hide the line sets in paintable covers matched to your house and set the condensers where they stay out of the way. On historic buildings in Rensselaer we’ve concealed the entire run to keep the original look intact.
One head in the hallway can’t cool four bedrooms; it just runs flat-out and runs up your bill. But if you’ve got central air and one tricky bonus room or addition, a single zone is the right call. We size to the job, not the invoice.
We visit, figure out whether it’s really a single-zone or a multi-zone job, and run a Manual J load calc — so the system’s sized to your actual house, not a square-footage chart.
You get a flat, all-in quote with equipment, labor, and rebate savings spelled out. No surprises.
Our crew installs your mini-split — usually in a day or two — and cleans up when we’re done.
We test everything, show you how it runs, and file your NY Clean Heat paperwork for you.

Senville Pro ContractorCost depends on how many rooms you want to condition, the size and brand of the system, and your home’s layout. Because every home is different, we give you a free in-home estimate with a flat, all-in price — and we apply any NY Clean Heat rebates you qualify for. Financing is available.
Yes. Modern ductless heat pumps are built for cold climates and keep heating efficiently well below 0°F, so a single system handles both winter heat and summer cooling for homes throughout the Albany–Schenectady–Troy area.
No — that’s the whole point of ductless. The indoor units mount on your wall or ceiling and connect to the outdoor unit through a small line set. It’s ideal for older homes, additions, and rooms that are always too hot or too cold.
Most installs are done in one to two days, depending on how many zones you’re adding. We schedule around you and clean up when we’re finished.
Astello is a NY Clean Heat participating contractor, so we file your rebate paperwork for you and the savings come right off your project — you don’t have to chase anything down.
Depends on the job, and we’ll tell you straight. If you’ve got central air and just one trouble spot — a bonus room, a laundry room, an addition that’s freezing in winter or baking in summer — a single-zone unit is often all you need. But one head in a hallway won’t cool four upstairs bedrooms; it’ll run flat-out, draw more power, and still leave rooms uncomfortable. When the load’s spread across the house, a multi-zone system actually costs less to run, because each head only works as hard as its room needs. We size to the result, not the number of heads.
We install Mitsubishi Electric, Cooper & Hunter, and Senville ductless systems, and we’ll recommend the right fit for your home and budget. We also service most major brands.
