The Brownstone Problem
A Brooklyn brownstone is one of the hardest homes in the country to heat and cool well — and one of the most expensive to get wrong. Most were built before central air existed, with no room for ductwork, plaster-on-lath walls you can't casually open, and parlor floors, garden levels, and top-floor bedrooms that all want different temperatures. Layer on a historic-district facade you can't alter at will, and the off-the-shelf answer — a noisy condenser bolted to the front and a window unit in every room — is exactly what a careful owner is trying to avoid.
Done right, climate control in a landmark home is something you feel and never see. That is the work we specialize in: discreet, quiet, multi-zone comfort that respects the architecture and the neighbors.
Three Ways to Cool a Brownstone — Honestly Compared
There is no single right answer; the best system depends on your floor plan, your ceilings, your budget, and how much disruption you will tolerate. Here is how the real options compare.
High-Velocity Small-Duct
Systems like Unico and SpacePak push air through flexible 2-inch mini-ducts that snake through wall cavities, closets, and chases — no soffits, no dropped ceilings. The supply outlets are small round or slotted vents you will barely notice. It is the most discreet way to get true central air into a finished period home, and the most cost-effective time to install it is while walls are already open during a renovation.
Best for: whole-home central air during a gut or partial renovation; owners who want minimal visible equipment.
Concealed Ducted Mini-Split
A compact air handler hides above a closet, hallway soffit, or dropped section of ceiling and feeds a few rooms through short duct runs and flush grilles. You get the zoning and efficiency of a heat pump with almost none of the visible hardware — an excellent middle path, floor by floor.
Best for: per-floor comfort, heating and cooling from one system, homes where full small-duct is not practical.
Wall-Mounted Mini-Split
The familiar ductless head on the wall. It is the least invasive and least expensive to install, highly efficient, and genuinely quiet — the trade-off is a visible indoor unit. With thoughtful placement it disappears into the room better than most people expect, and it is often the right call for a single room or a rear addition.
Best for: single rooms, additions, tighter budgets, or homes where opening walls is not on the table.
We install and service all three. We will walk your home, look at how the floors are actually used, and recommend the approach that fits — not the one that is easiest for us. Estimate your load or book a consultation to start.
Landmark & Historic District Work
If your home sits in a Landmarks Preservation Commission (LPC) historic district, what goes on the facade, roof, and rear yard is regulated — and that is usually exactly where the condenser and exterior equipment want to go. We design the equipment side so it is straightforward to approve:
- Condensers placed and screened at the rear or below the parapet, out of sight from the street wherever possible
- Line-set routing planned to avoid penetrations through protected facade elements
- Clean, reversible mounting that respects the building fabric
To be clear about what we do and do not do: we coordinate with your architect or expediter on the HVAC portion of an LPC submission — equipment specs, locations, and screening details — so the mechanical side does not hold up your approval. We do not file LPC applications on your behalf; that is your architect's role. What we promise is to make the equipment easy to say yes to.
Why Owners Trust Fixar With a Landmark Home
One Accountable Craftsman
In a multimillion-dollar home, who actually does the work matters. You get Egor on the job — the same person who designed it — not a rotating crew learning your house for the first time.
Quiet, Discreet Installs
Vibration isolation, careful placement, and right-sizing so the system runs low and quiet. See how we build for quiet →
Salt-Air Discipline
On the Brooklyn and Greenpoint waterfront, salt air eats equipment early. We bring the same corrosion-aware precision from our marine and yacht work to waterfront homes.
Respect for the Home
Shoe covers, drop cloths, careful protection of finishes, and a clean site every day. We work in homes where the floors and plaster are part of the value.

Can you put central air in a brownstone with no ductwork?
Yes — that is a core part of what we do. The two best routes are high-velocity small-duct systems (Unico/SpacePak), which thread flexible mini-ducts through existing wall cavities and closets, and concealed ducted mini-splits that serve a floor from a hidden air handler. Both deliver true central comfort without the soffits and dropped ceilings a conventional system would require.
Will the work damage my plaster or historic details?
Minimizing that is the entire point of how we design these systems. We route through existing cavities, closets, and chases wherever possible, plan access points carefully, and protect finishes throughout. Choosing the least-invasive option for your specific home is part of the consultation.
My home is in a historic district. Can you handle the Landmarks side?
We design and place the equipment so it is LPC-friendly — discreet rear or below-parapet condensers, screening, and routing that avoids protected facade elements — and we coordinate the HVAC details with your architect's submission. We do not file LPC applications ourselves; your architect does that. Our job is to make the mechanical side easy to approve.
When is the best time to install?
If you are renovating, plan HVAC early — while walls and ceilings are open, small-duct and concealed systems go in far more cheaply and cleanly than after the finishes are back. If you are not renovating, ductless and concealed options still work well; we design around your finished home.
Do you work on the Brooklyn waterfront?
Yes — Williamsburg, Greenpoint, DUMBO, and the brownstone belt. On the waterfront we spec and protect equipment for salt-air corrosion, applying the same discipline we use on marine and yacht systems.
