Is no AC in July an emergency?

Usually not, unless someone in the house is at risk of heat illness. It is uncomfortable, and a same-day call is priced as emergency labour. Check the filter and the breaker first.

What do I do if I smell gas?

Leave. Call the gas utility from outside. Do not switch lights or phones inside.

The outdoor unit is iced over. Emergency?

Urgent for the machine, not 911. Turn it off. Running an iced system is how a $200 airflow problem becomes a compressor.

Is this an emergency, or an uncomfortable Tuesday

Gas smell and a carbon-monoxide alarm mean leave the house. Ice on the suction line means turn it off and call. No cooling on a hot day is miserable and is priced as emergency labour if you book it that way — it is not 911 unless heat illness is a risk in the house.

Leave if you can smell gas or the CO alarm is sounding Those two are not HVAC bookings. Call the gas utility or emergency services from outside. HyreHVAC is not an emergency service and does not dispatch technicians.

Pick the symptom. Gas or CO: leave. Burning electrical smell: shut it off at the disconnect. Ice on the line: shut it off before the compressor dies. No heat when pipes can freeze is time-critical; no cooling is usually not. After-hours labour is commonly 1.5 to 2× and a call-out fee — ask the rate before the van is rolling, except when the instruction was already to leave.
