Emergency HVAC Repair in Londonderry, NH

Emergencies Move at Phone Speed

If your Londonderry home is unsafe — freezing, sweltering, or smelling of gas — don't type, dial. Calls to (603) 506-4389 get answered and routed to an available tech ahead of every routine appointment.

Emergency Checklist

• No heat below freezing — act before pipes do
• No AC in dangerous heat with kids, seniors, or pets home
• Propane or gas odor — leave, call your supplier or 911, then arrange repair
• CO alarm — out of the house and 911 first, always
• Burning smell or visible smoke from HVAC equipment

While the Tech Is En Route

• No heat: confirm thermostat, switch, breaker — and check your propane gauge if you're on a tank
• No cool: breaker, filter, and fan-only mode if the lines have iced
• Never run a generator or grill indoors or in the garage
