For Emergencies, Always Call
The form is for problems that can wait until tomorrow. A Merrimack home with no heat in January or no AC during a heat emergency should call (603) 506-4389 — calls are answered and dispatched ahead of all routine work.
Emergency Situations
- No heat in freezing temps — especially overnight with children in the house
- No AC during heat advisories with infants, seniors, or medical conditions
- Gas odor anywhere — evacuate first, call Liberty/911, then repair
- CO alarm sounding — out and 911, no exceptions
- Burning smells from vents or equipment
Meanwhile, at the House
- No heat: thermostat batteries, the switch that looks like a light switch, the breaker — check all three before assuming the worst
- No cool: breaker and a fresh filter solve more than you'd think; iced lines mean fan-only
- Bundle the vulnerable rooms: close doors, gather everyone in one heated/cooled space if needed
