⚠️ Warning Signs You Need Emergency HVAC Service

  • ⚠ Total AC failure when outdoor temperatures exceed 95°F — immediate health risk for elderly, children, pets
  • ⚠ Furnace failure when indoor temperatures drop below 55°F — pipe freeze risk begins
  • ⚠ Carbon monoxide detector alarming — evacuate immediately and call 911 and your gas company
  • ⚠ Burning smell or smoke visible from HVAC equipment — shut off system and call fire department if smoke is significant
  • ⚠ Refrigerant leak — hissing noise, ice on refrigerant lines, or sharp chemical smell from AC unit
  • ⚠ Electrical sparking or burning smell from air handler or outdoor unit — shut off power immediately

What to Do: Step-by-Step

  1. 1 If temperatures are dangerous (above 100°F inside or below 40°F inside), call emergency services or go to a public cooling/warming center
  2. 2 Call multiple HVAC companies simultaneously — during heat waves and cold snaps, the first available technician wins
  3. 3 Check that the issue isn't something simple: circuit breaker, thermostat batteries, clogged filter, tripped emergency switch
  4. 4 Ask the dispatcher for an ETA and whether the technician will have common parts on the truck
  5. 5 Document the symptoms clearly for the technician — when it started, unusual sounds or smells, what you've already checked
  6. 6 Be prepared to approve repair costs on the spot — technicians need authorization to proceed
  7. 7 After the emergency repair, schedule a full diagnostic to ensure no underlying issues contributed to the failure
