Murray Hill HVAC work runs into a problem most Manhattan neighborhoods don’t have: pre-war buildings with original steam heat, add-on cooling, and mechanical rooms squeezed into spaces never designed for modern equipment. That changes how a repair is diagnosed, how an install gets planned, and who should do the work. Coldharbour Heating & Air handles AC repair, furnace repair, and AC installation across Murray Hill with written pricing handed over before any tool comes out, and a 365-day guarantee on every repair. Call (934) 465-5501 and a live person answers, day or night.
Why Murray Hill Homes Are Different
Most of Murray Hill’s housing stock went up in the 1920s and 1930s: elevator buildings and rowhouses, many still running the original steam heat. That means radiators, risers, and building-wide controls rather than individual furnaces in every unit. When one apartment loses heat, the problem often lives in the basement, in a riser loop that serves twelve other units. Diagnosing it means reading the whole system, not just the cold radiator in front of you.
Cooling is its own puzzle. Ductwork is rare in Murray Hill. What you find instead are through-wall AC sleeves and window units that work hard in July and often still leave apartments humid. The East River sits a few blocks east, pushing damp summer air into buildings that were never sealed for it. In winter, the same river funnels wind down the numbered streets, and uninsulated steam pipes bang and sweat inside walls. Technicians who work Murray Hill regularly learn to expect tight mechanical closets, co-op board rules about hours and noise, and basements where old steam mains run inches from newer electrical panels. None of that is unusual to us; it’s just what the neighborhood is.
Styles & brands we work with
Our Main Murray Hill Services
These are the three jobs Murray Hill homeowners call us for most. Each has its own page with pricing detail, what to expect, and answers to the questions that come up in pre-war buildings specifically.
AC Repair in Murray Hill
Window units and through-wall ACs fail differently than central systems, and in Murray Hill the humidity makes a weak cooling coil obvious fast: the apartment drops to 74 but feels like 80. We diagnose compressor issues, refrigerant leaks, failed thermostats, and clogged condensate lines that drip into the apartment below. Most repairs run $150 to $650, and the quote is written down before we touch anything. If the fix doesn’t hold, we return at no charge for a full year. AC Repair in Murray Hill
Furnace Repair in Murray Hill
In Murray Hill, furnace repair often means working on the building’s steam boiler or the unit in a converted townhouse, not a suburban basement furnace. A single building-wide thermostat can leave top-floor tenants roasting while the garden level stays cold, and the fix is usually in the basement: adjusting the riser loop, replacing a stuck vent, or repacking a valve. Repairs typically fall between $150 and $700. We carry common parts for Carrier, Trane, and Lennox boilers so the first visit often finishes the job. Furnace Repair in Murray Hill
AC Installation in Murray Hill
Full AC installation in Murray Hill usually means one of two projects: replacing a dead through-wall unit, or retrofitting a pre-war apartment that never had central air. Without ductwork, the right answer is often a ductless mini-split system, sized to the room and installed around co-op board rules about condenser placement. A complete installation runs $3,500 to $7,500 depending on the number of indoor heads and the building’s constraints. The price is fixed in writing before the install date, not after the walls are open. AC Installation in Murray Hill

What Murray Hill Customers Say
"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."
- Doug Feeney"New mini split for the addition. Clean install, on time two days running, and the price matched the written quote to the dollar."
- Yvonne Prewitt
