Fujitsu HVAC Installation & Service in NYC
Fujitsu makes the quietest residential ductless on the market and the smallest concealed-duct air handlers in the industry — both real advantages in NYC apartments and pre-war buildings where neighbors are 12 inches away through a wall and the parlor floor ceilings clear at 8'6". Our team has installed Halcyon and Airstage systems across the city for over a decade.

TEAM EXPERIENCE
Why our team is the right Fujitsu installer in NYC
Fujitsu has two technical advantages over the rest of the residential ductless catalog: the quietest indoor units in the industry and the smallest concealed-duct air handlers anyone makes. Both translate directly to better NYC installs — but only if the contractor knows when to use them. Here is what a decade with the brand looks like in practice.
From Halcyon residential ductless to Airstage VRF — we work the full Fujitsu catalog
Fujitsu product lines we install and service
Halcyon residential ductless
Fujitsu's flagship residential line — Halcyon RLS single-zone wall-mounted units (the quietest in the industry), AOU/AOUM multi-zone outdoor units feeding up to 8 indoor heads, and a full range of indoor unit styles for any room type.
Custom Slim Duct concealed-duct
The smallest concealed-duct air handler in the industry — fits soffit chases that Mitsubishi and Daikin cannot. Our go-to for NYC pre-war buildings where central-air-style hidden ductwork is the goal but ceiling clearance is the constraint.
Halcyon Hyper Heat & Extra Low Temp
Cold-climate variants rated for capacity at low ambient temperatures — full operation down to -15°F on Extra Low Temp models. For NYC homeowners who want to retire a gas furnace and run heat pump only.
Airstage VRF (J-Series, V-Series)
Fujitsu's commercial VRF lineup — J-Series for small to mid commercial buildings, V-Series for full commercial heat pump and heat recovery systems. The smaller-scale alternative when full Daikin VRV or Mitsubishi City Multi is overkill for the building.
We install Mitsubishi, Daikin, and LG far more often than Fujitsu by raw volume. But two specific NYC scenarios point to Fujitsu first. First: pre-war buildings with low ceilings — Manhattan brownstone parlor floors, walk-up apartments, finished basements — where hidden ductwork is the goal and Mitsubishi PEAD or Daikin FXFQ concealed-duct units physically do not fit. Custom Slim Duct fits, and the install looks invisible from below. Second: party-wall apartments and noise-sensitive homes — Brooklyn brownstone bedrooms next to a neighbor, doorman building units with sound-conscious boards. Halcyon RLS at 19 dB minimum is quiet enough that the unit disappears from awareness. If neither constraint applies, Mitsubishi or Daikin is usually a better fit.

OUR PROCESS
How we install Fujitsu systems
Same workflow every Fujitsu install — load calc first, fit-and-noise verification second, equipment from the catalog third. Order matters: the building tells us whether Fujitsu is the right brand, not the catalog page.
Site visit, fit & noise check
We walk the building, measure ceiling clearance for any concealed-duct considerations, check party walls and adjacent rooms for noise sensitivity, and run a real Manual J load calc. If the building points to Fujitsu (Slim Duct fit or noise constraint), we say so honestly.
Equipment selection from the catalog
We match the building to the right Fujitsu line: Halcyon RLS for quiet single-zone, AOU multi-zone for whole-house, Custom Slim Duct for low-ceiling concealed installs, Halcyon Hyper Heat for cold-climate, Airstage J/V-Series for commercial. Itemized quote with rebate math.
Permits, rebates, scheduling
DOB mechanical permits, Con Edison NYC Clean Heat filing, federal 25C tax credit documentation, board approval package (co-op/condo work), and freight elevator coordination — all before install day.
Install, commission, warranty registration
Clean install, full commissioning with documented startup readings (refrigerant charge, line-set pressures, FGLair Wi-Fi setup), and Fujitsu warranty registration filed on your behalf within the 60-day window.
FUJITSU-SPECIFIC ANSWERS
Fujitsu HVAC FAQ
Questions we get every week from NYC homeowners considering Fujitsu Halcyon, Slim Duct, and Airstage systems.
Fujitsu wins on two specific dimensions: noise level (Halcyon RLS at 19 dB is quieter than any competitor in residential ductless) and concealed-duct profile (Custom Slim Duct fits chases that Mitsubishi PEAD and Daikin FXFQ cannot). For party-wall NYC apartments, noise-sensitive bedrooms, or pre-war low-ceiling brownstone retrofits, Fujitsu is often the right pick. For cold-climate single-source heating, Mitsubishi Hyper-Heat and Daikin Aurora are equally strong choices. For commercial VRF, Daikin VRV and Mitsubishi City Multi tend to outperform Fujitsu Airstage. We model the choice during the load calc, honestly.
Halcyon is Fujitsu's residential ductless line — wall-mounted, ceiling-cassette, and floor-mounted indoor units paired with single or multi-zone outdoor condensers. Custom Slim Duct is the residential concealed-duct variant — small-profile air handlers designed to fit hidden in soffits and ceiling chases. Airstage is the commercial VRF lineup — J-Series for small-to-mid commercial buildings, V-Series for full commercial heat pump and heat recovery systems. Most NYC residential work is Halcyon or Slim Duct; commercial work is Airstage.
Yes, by published manufacturer specs. Halcyon RLS indoor units run as low as 19 dB on minimum fan speed — Mitsubishi M-Series typically rates 22-25 dB minimum, Daikin FTXS 23-26 dB, LG Art Cool around 24-27 dB. The 3-5 dB advantage is small in absolute terms but noticeable in real rooms — particularly in NYC apartments with thin party walls and downstairs neighbors who pick up vibration through the floor. For bedrooms and quiet living spaces, the difference is real.
Custom Slim Duct air handlers are physically smaller — typically 7-8 inches deep versus 9-12 inches for Mitsubishi PEAD or Daikin FXFQ equivalents. For pre-war NYC buildings with original ceiling heights and limited soffit depth above kitchens or hallways, that 2-4 inch difference is the line between 'fits invisibly' and 'requires dropping the ceiling.' We measure the available chase before quoting, and Slim Duct gets specced when the constraint is real.
Standard Halcyon residential warranty is 12 years on the compressor and 7 years on parts when the system is registered with Fujitsu within 60 days of installation by a qualified contractor. We register every install on your behalf as part of project closeout. Owners who skip this step often discover only a 5-year warranty later, when something fails. Commercial Airstage warranties run 5-7 years depending on product line.
Yes — most of our Fujitsu service work is on systems we did not install. We carry the diagnostic tools and refrigerant equipment needed for the full Fujitsu catalog: Halcyon RLS controller diagnostics, AOU multi-zone refrigerant rebalancing, Slim Duct airflow troubleshooting, FGLair Wi-Fi connectivity, R-410A and R-32 work. We honor the manufacturer warranty if the system is still in coverage and provide a clean diagnostic report you can take to the original installer if the issue points back to install error.
