We are specialists in PTAC installation and repair, fan coil unit services, water source heat pump (WSHP) systems, ductless mini splits, and central HVAC – purpose-built for the unique demands of NYC’s dense urban buildings.
Based at 175 Pearl St, Brooklyn, NY, our certified technicians operate across Manhattan, Brooklyn, Queens, The Bronx, and Staten Island, delivering efficient, code-compliant HVAC solutions with same-day and 24/7 emergency response capabilities.
At Flow HVAC NYC, our mission is to deliver superior HVAC services that enhance year-round indoor comfort for New York City property owners while prioritizing energy efficiency, transparent pricing, and lasting workmanship. We don't just install systems; we build long-term comfort relationships with every client we serve, from a single PTAC unit in a Brooklyn apartment to full commercial HVAC systems in Manhattan office buildings.
As a full-service AC contractor and HVAC contractor in Brooklyn, Flow HVAC NYC covers the complete spectrum of heating, cooling, and ventilation needs for NYC's residential, commercial, and mixed-use properties:
Packaged Terminal Air Conditioners are the standard climate control solution for NYC hotels, apartment buildings, condos, and co-ops. Our PTAC contractors are trained on all major brands including Friedrich, LG, GE, and Amana — handling new installations, sleeve replacements, full unit repairs, and preventive maintenance.
We install, repair, clean, and replace fan coil units across NYC's high-rise residential and commercial buildings. Services include drain line cleaning, airflow balancing, coil cleaning, and full system upgrades for maximum efficiency.
Our WSHP-certified technicians provide complete water source heat pump installation, repair, water loop inspection, and energy efficiency upgrades for NYC condos and commercial buildings with shared water loop systems.
We design and install ductless mini split systems from leading brands including Daikin, Fujitsu, Mitsubishi, LG, and Carrier, ideal for NYC apartments, brownstones, and commercial spaces that lack existing ductwork.
From rooftop packaged units to full central air systems, our team provides custom ducted HVAC solutions for commercial buildings, retail spaces, healthcare facilities, schools, and large residential properties.
New York City buildings demand more from HVAC contractors than anywhere else in the country. Dense urban construction, aging building infrastructure, strict NYC building codes, and the extreme seasonal swings from freezing winters to sweltering summers mean that experience, licensing, and local knowledge are non-negotiable. Here's why hundreds of residential and commercial clients across all five boroughs trust Flow HVAC NYC:

A PTAC unit is also called a through-the-wall air conditioner, wall sleeve unit, packaged terminal unit, or hotel air conditioner.
In NYC co-ops and apartment buildings it is sometimes referred to simply as a wall unit or sleeve AC. The term "packaged terminal" refers to the fact that both heating and cooling are packaged into a single terminal unit installed through the wall.
You can self-install a PTAC only if an existing wall sleeve and dedicated 208–230V circuit are already in place. Everything else requires a licensed contractor in NYC.
If the job involves cutting a new wall opening, pouring masonry support, or running new electrical wiring, NYC law requires a licensed HVAC contractor and electrician. Unlicensed electrical work can result in fines and failed building inspections. Contact (212) 731-8383 for PTAC Installation anywhwere in NYC
Multiply the unit's age (years) by the repair cost. If the result exceeds $5,000, replace rather than repair.
For example, a 9-year-old PTAC needing a $600 repair scores 9 × $600 = $5,400 - suggesting replacement is the smarter financial choice. This rule applies to PTAC units, central AC, and heat pumps alike. Call (212) 731-8383 to get your unit evaluate today!

We work with all major HVAC brands including Carrier, Trane, Lennox, Goodman, and more. Our technicians are trained to service a wide variety of systems.
If your PTAC unit is over 10–15 years old, requires frequent repairs, or causes high energy bills, replacement may be more cost-effective.
Grinding, rattling, buzzing, or banging sounds may indicate loose components, motor issues, airflow restrictions, or worn mechanical parts needing attention.
