HVAC Emergency? We're On the Way.
No heat in January or no AC in July isn't inconvenient — it's dangerous. NSX runs a real 24/7 emergency dispatch line answered by real people, not voicemail.
When to call the emergency line.
Any of these situations — day or night, weekend or holiday — call us right away.
No heat in cold weather
Furnace out when outside temps are below 40°F is a true emergency, especially with children or elderly.
No AC in a heat wave
When indoor temps climb above 85°F, it stops being uncomfortable and starts being dangerous.
Gas smell
Suspected gas leak from a furnace or boiler — leave the home immediately and call us and 911.
Carbon monoxide alarm
CO detector going off near your HVAC — evacuate, ventilate, and call us for immediate inspection.
Major water leak
AC or boiler leaking into ceilings or walls — call us before damage compounds.
Electrical burn smell
Anything electrical burning from your HVAC — shut off power at the breaker and call us right away.
