AfterFast, Reliable Furnace Repair Across Newark
Furnace repair in Newark typically costs $150-$700, and most calls are completed same day when you reach us before early afternoon. Our Furnace Repair in Newark crews work the Ironbound, North Ward, and Downtown neighborhoods daily, so we know the narrow stairwells and basement mechanical rooms that come with pre-WWII brick row houses and tenements.

Call (817) 402-2972 and a live person answers, 24 hours a day, every day of the year.
Why Coldharbour Heating & Air Is Newark’s Preferred Furnace Repair Company
We’ve been part of the Kingswell network since 2003, and our independently owned operation has built a reputation in Newark by doing what we say we’ll do. Homeowners and landlords here have been burned by no-shows and price jumps, so we put four promises in writing every time: the price before the work starts, a firm arrival window, a clean job site, and our 365-Day Done Right Promise.
Our technicians are background-checked, uniformed, and trained on nine major brands including Rheem, York, and Daikin. They carry the parts that fail most often on Newark’s aging steam and forced-air systems, which means fewer return trips and less waiting for tenants who need heat tonight. We’re not the cheapest outfit that advertises in Essex County. We’re the one that comes back for free if the repair fails within a full year.
Heating Repair in Newark
Heating Repair in Newark means something different than it does in suburban towns with new construction and forced-air furnaces in clean basements. Here, you’re often dealing with cast-iron steam boilers from the 1960s through 1980s, serving two to four tenant units in a brick row house with no ductwork and a mechanical room the size of a closet. We handle everything from failed pilot assemblies and cracked heat exchangers to complete control replacements on systems that have been jury-rigged by three previous contractors.
Most heating repairs in Newark run $150-$700, depending on whether we’re replacing a $180 ignitor or rebuilding a gas valve and controls on a commercial-grade boiler. We hand you the written price before touching a tool.
Steam Boiler Diagnosis and Balancing
One-pipe steam systems develop water hammer, uneven heat, and radiator knocking when condensate can’t drain back to the boiler. Our techs check pipe pitch, air vent function, and boiler pressure before recommending any replacement. We’ve saved landlords thousands by re-pitching a main that another company wanted to tear out.
Emergency No-Heat Calls
A failed boiler in a multi-unit building is a code violation in Newark, not a tomorrow problem. We prioritize these calls, and our trucks carry universal replacement parts for the most common steam and hot-water boiler models found in Essex County.
Boiler Repair in Newark
Boiler Repair in Newark is the core of what we do, even when homeowners call it our Furnace Repair in Newark. The city’s housing stock, overwhelmingly built between 1890 and 1940, relies on cast-iron steam boilers that heat multiple units through one-pipe radiator systems. These boilers live in cramped basements, narrow utility closets, or rooftop mechanical sheds with access ladders that would make a suburban HVAC tech turn around.
Boiler repairs in Newark fall in that same $150-$700 range for most common failures. A cracked heat exchanger on a small residential boiler might run toward the higher end. A failed pressure relief valve or circulator pump stays on the lower side. We diagnose first, price second, and start work only when you’ve approved the written estimate.
Multi-Tenant System Access and Coordination
Landlord-owned buildings with one boiler serving multiple units create complications most single-family HVAC companies don’t encounter. We coordinate entry, document which units are affected, and provide written findings the owner can use for insurance or code compliance. Our guarantee covers the repair regardless of which tenant calls it in.
Rooftop and Closet Installations
Newark’s dense construction means equipment gets stuffed wherever it fits. We’ve pulled failed boilers through 28-inch doorways and repaired gas valves on units mounted to roof parapets with nothing but a ladder and a hand truck. These jobs take longer. We build that into the estimate upfront.
Trusted Brands We Service in Newark
Our technicians train continuously on Rheem, York, Daikin, Bryant, and five other major residential brands. We stock the ignitors, blower motors, gas valves, and control boards that fail most often on equipment installed in Newark’s 1980s and 1990s housing renovations, plus the universal retrofit parts that keep 1960s steam boilers running another season. Because we carry inventory rather than ordering everything next-day, most repairs finish in a single visit. That’s the difference between a tenant sleeping with heat tonight and waiting 48 hours for a parts delivery.
Common Furnace Repair Problems We See in Newark Homes
- Water hammer in one-pipe steam systems. In the Ironbound’s wall-to-wall row houses, decades of foundation settlement shift pipe pitch so condensate pools in mains instead of draining back. Tenants call it “the furnace banging” and assume the boiler is shot. Usually it’s a $150-$280 vent and pitch correction.
- Failed heat exchangers on aging boilers. A cracked exchanger on a 1970s cast-iron boiler can dump carbon monoxide into living spaces. We test every boiler with a combustion analyzer, and if the exchanger is compromised, we show you the readings and price a replacement before any work begins.
- Inaccurate thermostats in closet-mounted systems. When a furnace or air handler lives in a hallway closet, the thermostat often sits in the return air path or catches radiant heat from the unit itself. We relocate or shield sensors so the system responds to actual room temperature, not mechanical room temperature.
- Gas valve and control failures on landlord-maintained boilers. Deferred maintenance on multi-family boilers leads to erratic firing, pilot outages, and safety lockouts. We replace valves, rebuild controls, and document the repair for code inspectors who increasingly require written service records.

FAQs About Furnace Repair in Newark
It’s almost always repairable. That banging is water hammer, caused by condensate trapped in one-pipe steam mains that have lost their pitch as the foundation settled. We re-pitch the main, replace failed air vents, and balance the system so all units heat evenly. Full replacement is only necessary if the boiler block itself is cracked or the heat exchanger has failed. Call (817) 402-2972 and we’ll diagnose it properly.
Yes, regularly. Downtown Newark and the North Ward have equipment crammed into mechanical closets, former coal bins, and rooftop sheds that were never designed for modern HVAC. We bring the tools and rigging for tight spaces, and we build the extra labor into our upfront written estimate.
Yes, and we handle the access coordination that single-family techs won’t touch. We document which units are affected, provide written findings for your records, and guarantee the repair for 365 days regardless of which tenant reports the problem. A failed boiler in a multi-unit building is a housing code emergency in Newark, and we treat it that way.
The thermostat is likely sensing return air temperature or radiant heat from the unit itself rather than actual room temperature. We relocate or shield the sensor, verify calibration with a digital thermometer, and sometimes install a remote sensor in a representative room. It’s a common fix in Newark’s converted row houses where equipment was shoehorned into spaces never intended for it.
Yes. Because Newark’s pre-WWII housing stock has zero ductwork, ductless mini-splits are often the only practical way to add cooling. We repair and maintain Daikin and other major-brand mini-splits, including refrigerant leaks, compressor issues, and control failures. If your building has steam heat and no ducts, AC Installation in Newark via mini-splits is probably your best cooling option, and we service them with the same upfront pricing and 365-day guarantee.
