Some Buildings Can't Wait Until Morning
Emergencies scale with buildings. A cold single-family is one miserable household; a dead boiler under a three-family is three, plus a landlord's obligations, plus every pipe in an old structure that was never insulated to modern standards. When the situation is genuinely urgent, skip the form and call (603) 506-4389. A phone call describes the building. It does not reserve a visit.
Call Right Now If
- Heat is down in freezing weather — in any building, but especially one with tenants, elderly residents, or a history of frozen pipes
- A rental or vacant unit is going cold — an unheated vacant floor can burst pipes and flood every unit below it
- Cooling has failed in dangerous heat with infants, elderly family, or anyone medically vulnerable on an upper floor
- You smell gas anywhere in the building — get everyone out first, call the gas utility or 911 from outside, and only then think about repairs
- A CO alarm is sounding — evacuate every unit and call 911 before anything else; old shared flues make this a whole-building event
- Anything around the boiler or furnace is smoking, sparking, or leaking hot water
While Help Is on the Way
- No heat: confirm the thermostat, the emergency switch at the top of the basement stairs (it looks like a light switch and gets bumped), and the breaker — then open faucets to a drip on any plumbing in outside walls
- Steam boiler acting up: check the sight glass — if no water is visible, shut the system off and leave it off; a dry-fired boiler is a destroyed boiler
- No cooling: check the breaker and the filter, and if the refrigerant lines have iced, switch to fan-only so the coil can thaw before the tech arrives
- Space heaters: plugged straight into wall outlets with clearance all around — never into a power strip, and never left running in an empty unit
