Furnace Repair in Galloway, NJ

Furnace Repair in Galloway

The systems we see in Galloway tend to share a history — a heating system replaced once or twice, cooling added later, and ductwork extended as rooms were added rather than designed for the house as it now stands. Most comfort complaints here start there.

81% of homes in Galloway heat with natural gas, so furnace and boiler work is the bulk of what comes up here. (US Census ACS 2022)

Why has my furnace stopped?

Modern furnaces are conservative — they shut themselves down rather than run in a state they do not like. That makes most no-heat calls a matter of finding which safety tripped and why.

A failed igniter

Hot-surface igniters glow to light the burners and they are consumable — most last five to ten years and then crack. The symptom is a furnace that goes through its sequence, the inducer runs, and then nothing lights. It is one of the cheapest parts on the appliance and one of the most commonly replaced.

A dirty flame sensor

A thin metal rod sits in the flame and confirms it is actually burning. It accumulates a film of oxide, stops sensing reliably, and the control board shuts the gas valve within seconds as a safety response. The classic symptom is a furnace that lights, runs for three to five seconds, and shuts off — repeatedly. Cleaning it takes minutes.

A blocked condensate line

High-efficiency condensing furnaces produce acidic water as a by-product and drain it. When that line blocks or freezes, a float switch shuts the furnace down. This is a common New Jersey call in a cold snap, particularly where the line runs to an exterior wall or an unheated garage.

A limit switch tripping on airflow

This is the one worth knowing about. If airflow across the heat exchanger is restricted, the furnace overheats and the limit switch cuts it out. The symptom is a furnace that heats, then stops before the house is warm, then restarts a few minutes later. Nine times in ten the restriction is a filter nobody has changed. Check that before you call anyone.

A cracked heat exchanger, and why it ends the argument

The heat exchanger is the metal barrier between the combustion gases and the air circulating through your house. It is the entire reason a furnace is safe. When it cracks, combustion products — including carbon monoxide — can pass into the supply air.

Why it is not repaired

Nothing is welded or patched. A cracked exchanger means the furnace is condemned, and a technician finding one will red-tag the appliance and shut off the gas. That is the correct response and not an upsell, though it is worth understanding the difference: a genuine finding is demonstrable. Ask to be shown the crack, or the combustion analysis reading, or the camera image. A contractor who has found one will have no difficulty showing you.

Get a second opinion if you are unsure

This is an expensive diagnosis and it is occasionally made loosely. If the furnace is not obviously at end of life and you were not shown evidence, a second inspection costs a fraction of a replacement. Any reputable firm expects this on a condemnation.

Working CO alarms are not optional

New Jersey requires carbon monoxide alarms in homes. On any level with a fuel-burning appliance or an attached garage, and outside sleeping areas. They are the backstop for exactly this failure and they expire — most have a service life stamped on the back.
