Gramercy’s heating and cooling work runs on older buildings, thick walls, and a lot of pre-war plumbing that was never designed for modern air conditioning. Coldharbour Heating & Air handles AC repair, furnace repair, and AC installation across the neighborhood, with written pricing handed over before any tool comes out and a live person answering the phone around the clock. If you need a technician who won’t disappear into a voicemail tree, call (934) 465-5501.
Why Gramercy Homes Are Different
Gramercy’s dense stock of pre-war co-ops and landmarked brownstones means HVAC work often requires navigating strict building board approvals, limited outdoor condenser space, and the need for high-velocity or ductless systems that preserve historic interiors. That’s a far more acute challenge here than in most of Manhattan, where newer construction at least left room for ductwork. Many of these buildings date to the late 19th and early 20th centuries, with thick masonry walls, original steam heat, and minimal or nonexistent duct runs.
In practice, that means a routine AC repair in a Gramercy brownstone can involve working around through-wall sleeve units, window lines, and condensation drains installed decades before today’s efficiency standards. Summers are hot and humid, pushing heavy cooling demand inside buildings that were designed before air conditioning existed. Winters require careful balancing of aging steam or hot-water heat with any newly added cooling system. Technicians who know Gramercy expect to match compressor replacements to exact sleeve dimensions, because a mismatched unit can mean costly masonry work no homeowner wants to open up.

Our Main Gramercy Services
These are the three jobs Gramercy homeowners call us about most, each with its own dedicated page and its own pricing details.
AC Repair in Gramercy
When a through-wall unit or split system stops cooling in July, the fix usually comes down to a failed capacitor, a refrigerant leak, or a compressor that’s finally given out after years of New York humidity. In Gramercy, access often means working inside tight mechanical closets or behind a sleeve that hasn’t moved in thirty years. We carry common parts for all the major brands and can typically diagnose and repair the same day. Read more about AC Repair in Gramercy.
Furnace Repair in Gramercy
Most Gramercy furnaces are tied into original steam or hot-water systems, which means a no-heat call in January is often a failed circulator pump, a stuck zone valve, or an igniter coated in years of dust. We work on all of it, from the boiler room to the radiator valve. Our technicians carry igniters, flame sensors, and pressure switches for every major brand, so the first visit usually gets heat back on. Read more about Furnace Repair in Gramercy.
AC Installation in Gramercy
Installing central air in a Gramercy co-op or brownstone is not a one-day job and we won’t pretend it is. The work requires a load calculation, building board approval paperwork, and often a ductless or high-velocity design that respects landmark restrictions and preserved interior walls. Some buildings only allow through-wall sleeves with exact dimensional limits, so compressor selection has to be precise. We quote a written fixed price before any work is scheduled and handle the paperwork with the board. Read more about AC Installation in Gramercy.

What Gramercy Customers Say
"Our upstairs never cooled right. He found the duct run was half blocked and the system low on charge, fixed both, and now the whole house is even. Explained every step."
- Deanna Boleyn"Signed up for a tune up before summer. He found a part starting to fail and showed me the reading, didn't just tell me to trust him. Fixed it then so we wouldn't get stuck in July."
- Sophia Tran"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."
