No heat on a freezing night is the call this page exists for. Emergency triage in Trenton runs 24/7 — true no-heat situations jump the queue, and you will ask about actual appointment availability on the first call. Read this first if the boiler just quit: what counts as an emergency, what to check while you wait, and what the triage will ask.
General inquiries: 7 AM–7 PM · Emergency calls: 24/7 · (888) 766-1474
Call immediately — or call the diagnosis line instead.
Not every boiler problem is an emergency, and the honest version of triage says so. Emergencies: no heat when temperatures are at or near freezing, active water leaking from the boiler, a suspected gas leak (utility first, see below), or a boiler running with unusual smells or visible sooting. Not emergencies: strange noises with heat still working, pressure gauges creeping down over weeks, a single cold radiator, or lockouts you can clear and that stay clear for days — those belong on the diagnosis and repair page.
Trenton's freeze risk is real even in a "mild" mid-Atlantic winter: January nights in the teens, wet cold, and rowhouse basements with old windows and uninsulated outside-wall runs. A no-heat outage in a cold snap is a freeze risk for pipes in outside walls, which is why no-heat calls get priority triage around the clock. When you call, the triage will ask for your ZIP, the fuel type, what the unit is doing, and how long it has been down.
Five minutes of calm checks, in order.
This is a utility call, not a boiler call.
If you smell gas near the boiler — rotten-egg odor, hissing at a fitting, or a faint smell that is getting stronger — leave the building. Do not touch switches, do not reset the boiler, do not investigate. Call the gas utility from outside. Trenton is gas-served almost everywhere, so this is the emergency rule every gas household should know by heart.
Only after the utility has cleared the building does boiler repair enter the picture. The emergency triage line can talk through what happens next once you are safe — which components the utility typically red-tags, and what the restart path looks like. The national emergency boiler repair page covers the general process in more depth.
One call, routed by situation.
The emergency line is answered 24/7, every day. You describe the situation in plain language; the triage asks for your Trenton ZIP, fuel type, and the unit's behavior; then true no-heat emergencies are routed first and you ask about actual appointment availability. Non-emergency symptoms get routed to the diagnosis page path instead — honest routing is faster than an emergency dispatch for a problem that isn't one.
Have these ready: the pressure gauge reading, any error code, how long heat has been out, and whether anyone in the household is vulnerable to cold. Those details determine priority, not page-reading. General inquiries run 7 AM–7 PM; the emergency line never closes.
Straight answers before you call.
Call (888) 766-1474 — emergency triage runs 24/7. Check the thermostat, breaker, and red emergency switch, then try one reset if the unit shows a lockout. Brick rows lose heat quickly, so keep faucets trickling and do not keep resetting a unit that will not stay lit.
Leave immediately, do not flip switches or touch the boiler, and call your gas utility's emergency line first. Only after the utility clears the building should the heating side be approached. Never restart a boiler yourself after any gas smell, no matter how faint.
Do not fire it dry — a dry-fired steam boiler can crack sections. Add water slowly only if you know the proper procedure for your unit; if the glass was fully empty or you are unsure, call for emergency service instead of guessing. Waiting for the professional is the right move here.
Shut off the boiler and close the heating system's water feed to limit the flooding, then contain the water. Do not refire until the valve is replaced and the system is refilled. In a rowhouse, an upstairs leak becomes a downstairs problem fast — call for emergency service now.
Yes — leave the area, get fresh air, and call 911 or the fire department first. Trenton's old converted boilers with aging venting deserve extra caution on CO. Do not silence the detector and do not restart the boiler; once responders clear the building, call (888) 766-1474 before it fires again.
Shut off the boiler and close the water feed to the heating system — a burst pipe drains the system and the boiler must not fire dry. Contain the water, then call for emergency service. Mention the garage freeze so the visit also addresses freeze protection for the exposed piping.

Once the emergency is stabilized, the diagnosis and repair page covers the deeper work — why the unit failed and what keeps it from failing again. If the fault is fuel-specific, the gas boiler page covers ignition and flame-sensing failures, and the oil boiler page covers burner and tank issues. When the visit reveals the block is finished, the installation and replacement page walks through sizing and replacement math. Nationally, emergency boiler repair explains the general triage process.
