Gas or propane smell
Don't use switches, appliances, or a phone inside. Get outside and call from a safe location.
A gas smell, carbon monoxide alarm, smoke, water near electrical equipment, or a home with unsafe indoor temperatures changes the next step. Don't troubleshoot through a safety event.
Leave for gas or propane odor and alarms, then call 911 or emergency services from outside. For an equipment failure without those hazards, tell us the symptom and turn off a system that's icing, leaking, smoking, or tripping again and again.
Don't use switches, appliances, or a phone inside. Get outside and call from a safe location.
The furnace may not be the source. Leave, call emergency services, and don't operate fuel-burning equipment until the home's cleared.
Shut the equipment off if it's safe. Water near electrical parts, smoke, scorching, and a breaker that trips more than once all need prompt attention.
Losing heat or cooling can turn urgent once the indoor conditions are unsafe for the people in the home. A system that still runs but is underperforming needs a diagnosis, but a safety alarm or active damage comes first.
Tell us what you can see and hear without opening the equipment. The difference between no heat, no cooling, odor, alarm, smoke, water, and a breaker trip matters.
For no heat without an odor or alarm, check the thermostat mode and its batteries, then the furnace switch and breaker once. Don't keep resetting a furnace that locks out.
For no cooling, close the blinds, move people to a cooler room, and turn off a system that's icing, leaking, or tripping. Don't use a portable heater near curtains, bedding, or an unattended room.
Once the home's safe, an HVAC visit can trace combustion, venting, electrical, airflow, drainage, or control problems. Our recommendation should state what caused the immediate issue and what work's needed.
Longer-term maintenance or replacement can wait until the safety question's settled.
Leave right away and call 911 or the utility from outside. Don't relight the pilot, use switches, or investigate from inside.
Leave and have the home checked anyway. A stopped alarm doesn't prove the source is gone or that the air's safe.
It turns urgent once the indoor conditions are unsafe or someone in the home can't safely relocate. Share the temperature, household risk, and any odor or alarm.
No. Check the thermostat and power once when there's no odor or alarm. Repeated lockouts need diagnosis from us.
Leave for gas, propane, smoke, fire, or a carbon monoxide alarm. For other failures, call with the symptom and what the system's doing.
