HVAC Service in Essex County
Essex heats with water. Behind the porches in Montclair, Glen Ridge and the Oranges sit cast iron radiators and boilers that have been converted twice and re-piped three times. HVAC in Essex County is mostly a hydronics job, and our shop is on Cortlandt Street in Belleville.
Hydronics Is the Local Trade
Steam and hot water are most of the heating stock here, and they fail in ways forced air never does.
Victorians, Radiators and a Century of Re-Piping
Montclair, Glen Ridge, South Orange, Maplewood and Essex Fells were built between the 1890s and the 1920s: balloon-framed, plaster over lath, three storeys with a finished attic, and not one duct chase anywhere in them. Heat came from a coal boiler in the cellar. That boiler became oil, then gas, and every conversion left its mark on the near-boiler piping. What we usually find is a header that no longer matches any manufacturer’s diagram, which is why the steam leaves the boiler wet and the radiators hammer.
Most of what gets blamed on an old boiler is not the boiler. A radiator at the far end of the main that never heats is a main venting problem. Banging is condensate trapped by a radiator pitched the wrong way or a wet return that has silted up. Short-cycling on pressure is a pressuretrol set for a building three times the size. Those are afternoons of work, not replacements, and we say so before we quote iron.
Belleville, Bloomfield, Newark and the older side of Nutley are a different problem: two- and three-family houses on one boiler, with the only thermostat in the first-floor apartment. The top floor bakes, the ground floor is cold, and nobody is wrong. Thermostatic radiator valves and correctly sized vents solve more of that than new equipment does. West of the ridge โ Livingston, Roseland, Cedar Grove, Verona โ the stock turns post-war and ducted, and the work turns back into load calculations and static pressure.
- One-pipe and two-pipe steam, hot water and hybrid systems
- Near-boiler piping rebuilt to the manufacturer’s drawing
- Cooling retrofitted into houses that never had ductwork
- Oil-to-gas conversions, including tank and chimney work
What Goes Wrong in Essex Houses
Our HVAC Services in Essex County
Weighted towards hydronics, because that is what the county is heated with.
Steam & Hot Water Boilers
Repair, replacement and the near-boiler piping that decides whether a new boiler behaves. Pressuretrols, low-water cutoffs, traps and vents.
Cooling for a Radiator House
Ductless heads, ceiling cassettes and small-duct high-velocity systems threaded through closets and joist bays, so a 1910 house gets air conditioning without losing its plaster.
AC Repair & Replacement
AC repair in Montclair, Nutley, Bloomfield and across the county, including the attic air handlers that the west-of-the-ridge splits and colonials all seem to have.
Oil to Gas Conversion
Plenty of Essex cellars still hold an oil burner and a tank. We handle the conversion, the venting and the chimney liner that the new appliance will need.
Humidity & Air Quality
Old houses run dry in a steam winter and damp in a July basement. Humidifiers, dehumidification and ventilation sized to the actual house.
People Who Actually Like Steam
Hydronics is a specialism, and it is thinning out. We kept it.
Steam Is Not a Side Line
Vents, traps, pitch, pressure and near-boiler piping. We diagnose the distribution before anyone talks about new iron.
Belleville Is the Base
Cortlandt Street sits in the middle of the county. Nutley, Bloomfield and Newark are a few minutes out; the Oranges and Livingston are a short run.
Careful in Old Houses
Plaster, original trim and finished third floors. Runs get planned so the cosmetic repair afterwards is small or nothing.
24/7 Emergency
A dead boiler in a three-family in February is not a next-week problem. The line is answered around the clock.
Read the System Before Replacing It
Call or Book
Tell us the fuel, the system type if you know it, and what the radiators are doing.
Survey the Distribution
Main vents, radiator pitch, trap condition, wet return and where the header actually goes.
Fix or Re-Pipe
Often venting and piping. Where the block really is done, we size the replacement from a room-by-room heat loss, not the old rating.
Balance and Verify
Pressure set low, every radiator brought up, and the building checked floor by floor before we leave.

What Essex Homeowners Ask
Can I get central air in a house with radiators?
Yes, and it is one of the most common jobs we do in Montclair and the Oranges. Two routes: small-duct high-velocity, where flexible two-inch tubing runs through closets and joist bays to small round outlets, or ductless heads and ceiling cassettes. High-velocity keeps the ceilings clean but needs a route for the air handler and trunk. Ductless costs less disruption and zones room by room. We walk the house and tell you which one it actually suits. See ductless systems.
Why do my radiators bang?
Condensate sitting where steam wants to travel. Usually a radiator that has lost its pitch back towards the valve, a sagged main, or a wet return that has silted up over the decades. Sometimes it is the boiler running at far higher pressure than a residential system needs. None of those are cured by a new boiler, and installing one without fixing them buys you the same noise on newer iron.
Do you do AC repair in Montclair, NJ?
Yes, throughout Montclair, Upper Montclair and Glen Ridge, on ducted systems, high-velocity systems and Mitsubishi ductless alike. A lot of the cooling in those neighbourhoods was retrofitted rather than original, so the diagnosis often starts with how it was installed rather than what failed. See the Montclair page.
My three-family has one boiler and nobody agrees on the heat.
Standard in Belleville, Bloomfield and Newark. One thermostat cannot represent three apartments with different exposures and different tenants. Thermostatic radiator valves on the upper floors, correctly sized vents on each radiator, and a properly vented main will even a building out without splitting the system. Where it genuinely needs zoning, we price that too.
Should I convert from oil to gas?
Depends on whether gas is already at the curb, what condition the tank and chimney are in, and how long you plan to stay. The conversion is rarely just the burner: an old masonry chimney serving a modern appliance usually needs a liner, and a buried tank needs proper decommissioning. We look at all three before recommending it, and we will also tell you when a heat pump makes more sense than either fuel.
Do you cover Nutley and the northern end of the county?
Yes. HVAC in Nutley, NJ is a short run from Belleville โ the two towns share a border, and our shop is minutes from Franklin Avenue. Bloomfield, Glen Ridge and Verona are the same neighbourhood as far as scheduling goes. See the Nutley page.
How old is too old for a boiler?
Cast iron sections outlive most other heating equipment, and a well-piped boiler from the 1980s can still be the right thing to keep. What ends them is a cracked or leaking section, a firebox that no longer holds, or a flue situation that cannot be made safe. Age alone is not a reason. A failing combustion test is.

Leaky ductwork can waste conditioned air before it ever reaches your rooms. Proper duct sealing helps improve airflow, reduce energy loss, and create more consistent temperatures throughout your home.

Indoor humidity affects more than comfort. Too much moisture can make your home feel sticky, while air that is too dry may cause irritation and discomfort.
Proper HVAC operation and humidity control can help create a healthier, more comfortable indoor environment throughout the year.

Your HVAC system often gives warning signs before a bigger problem develops. Test your thermostat, listen for unusual sounds, watch for moisture near drain lines, and keep the outdoor unit clear.
A quick response can help protect your comfort, prevent avoidable damage, and support reliable system performance all season long.
