Brooklyn Homes Were Never Built for Central Air more than you think
Tearing into plaster walls and ceilings of a Brooklyn brownstone to run ductwork costs a fortune and destroys the character of the home.
Walls you can't touch
Your pre-war Brooklyn brownstone has plaster and brick, so central ducts mean weeks of demolition and a brutal repair bill.
That one stubborn room
The top-floor or rear Brooklyn room bakes in August and freezes in January because heat and old radiators never reach it.
Window units every fall
Hauling heavy window ACs out each October and back each May is a Brooklyn ritual, and theft risk only makes it worse.
Bills that keep climbing
Old window units in a Brooklyn row house each pull their own power, and the combined summer bill shocks even veterans.
OUR SERVICES
Mini-Splits Built for Brooklyn
Brooklyn brownstones and row houses were built before central air existed. We install ductless systems that fit your home without tearing up walls.
Single-Zone Mini-Split
One Room, Addition or Office
One outdoor unit, one indoor head — perfect for the Brooklyn parlor floor that never gets enough heat, a garden-level home office, or a rear addition the ductwork never reached.
Multi-Zone Mini-Split System
Whole-Home Comfort, No Ducts
Run up to eight zones from one outdoor unit across your Brooklyn row house. Each floor or room keeps its own temperature without sharing ductwork that does not exist.
Commercial Ductless Systems
Shops, Server Rooms & Offices
Brooklyn storefronts, offices, and server rooms need reliable spot cooling. We size and install commercial ductless units that run quietly without disrupting your business day.

How We Install in Brooklyn
No hassle, no surprises. We handle everything so you can sit back and enjoy a perfectly climate-controlled space.
Home Visit & Zone Planning
We walk Brooklyn brownstone layouts room by room, noting ceiling heights, party walls, and window placement to determine how many zones you need and where each indoor head will sit without looking forced.
System Design & Quote
We specify BTU capacity, SEER2 rating, and line-set routing through Brooklyn tight interior walls. The written quote shows unit model, placement sketch, and total cost with no estimates that drift at install.
Clean Mini-Split Installation
Line sets run through interior walls or along conduit channels sized to match your Brooklyn home trim. We make one small penetration per zone, seal it against moisture, and leave no exposed wiring or open gaps.
Testing & Walkthrough
Each Brooklyn zone is pressure-tested, charged, and run through heating and cooling modes before we leave. We walk you through the remote, app controls, filter care, and your warranty terms in plain language.

FAQ
Questions We Hear Every Day
Honest, engineer-level answers — no sales fluff.
Knowing how to size a mini split hvac system starts with a Manual J heat-load calculation for each Brooklyn zone — square footage, ceiling height, window area, and wall insulation all factor in. Most Brooklyn brownstone floors run 350–600 sq ft, mapping to 9,000–18,000 BTU indoor heads. Oversizing a ductless mini-split causes short-cycling and humidity problems, while undersizing leaves rooms uncomfortable. Get the math right before purchasing equipment.
How long does ductless hvac installation take in a typical Brooklyn brownstone? A single-zone system is usually complete in four to six hours. Multi-zone installs with two or three indoor heads take eight to twelve hours, depending on line-set routing through masonry walls. Brooklyn's landmarked facades can add time if penetrations need to be planned carefully. Most homeowners have heat and cooling the same day the crew arrives.
How much is refrigerant for hvac systems? R-410A runs about $6–$10 per pound; newer R-32 systems cost slightly more. A standard ductless mini-split holds two to four pounds from the factory and arrives pre-charged. Brooklyn homeowners rarely pay refrigerant costs at installation — only at service if a leak has occurred. Topping off without finding the leak is a waste of money and illegal under EPA Section 608.
What does seer stand for in hvac? Seasonal Energy Efficiency Ratio — it measures cooling output per watt of electricity over a full season. Ductless mini-split systems routinely hit SEER 20–30, compared to 14–18 for central systems, because they eliminate duct losses. In Brooklyn row houses with no ductwork, that efficiency gap is even more pronounced. Higher SEER means lower Con Edison bills every summer month.
how to bypass low pressure switch on ac unit hvac is a search that leads to a firm answer: don't. That switch protects the ductless mini-split compressor from running without adequate refrigerant pressure — bypassing it risks catastrophic compressor failure. In Brooklyn, a replacement compressor plus labor runs $1,200–$2,000. A low-pressure fault means diagnosing the root cause — low charge, blocked filter, or faulty sensor — not circumventing the safety protection.
How much does a home hvac system cost for a Brooklyn brownstone with ductless mini-splits? A single-zone system installed runs $3,500–$5,500. A whole-home three-zone multi-split typically costs $9,000–$16,000 installed. Brooklyn homeowners can offset that with the federal 25C heat-pump tax credit (up to $2,000) and NYSERDA Clean Heat rebates. Compared to adding central ductwork through plaster walls, ductless is almost always the more affordable retrofit.
