When a cooling problem is an emergency

Not every issue needs an after hours truck roll. These do, and calling right away usually limits the damage.

No cooling at all during a heat advisory

If the indoor temperature is climbing and will not come back down overnight, treat it as urgent. This is the most common emergency call we take between June and September.

Burning smell or smoke from the equipment

Shut the system off at the thermostat and the breaker, then call. An overheating motor or scorched wiring is a safety issue, not a comfort issue.

Water actively leaking into the ceiling or living space

A backed up condensate line can do real damage quickly. Turn the system off to stop the water and call for service.

Loud grinding, screeching or a hard electrical hum

These usually mean a motor or compressor is failing right now. Continuing to run the unit tends to turn a repair into a replacement.

No heat on a cold desert night

Winter nights here drop into the 30s. A furnace or heat pump that will not produce heat is a legitimate after hours call, and we handle heating emergencies as well as cooling.

What to do before we arrive

A few minutes of prep often makes the visit shorter and sometimes solves it outright.

  • Switch the thermostat to off rather than leaving it calling for cooling
  • Check that the breaker for the air handler and condenser has not tripped
  • Look at the filter, a completely blocked filter can freeze a coil and stop cooling
  • Check for ice on the refrigerant line, if there is ice, run the fan only for a while
  • Confirm the outdoor disconnect near the condenser has not been pulled
  • Clear access to the attic hatch, closet or side yard equipment
  • Note exactly when the problem started and any noise or smell that came with it

What happens on an emergency call

The first goal is to get cooling running again safely. We diagnose the failure and explain what it will take to fix it before anything gets replaced.

If the repair needs a part that is not on the truck, we will say so directly and talk through the scheduling instead of leaving you guessing.

We do not create urgency to sell equipment. If the honest answer is that the system needs to be replaced, we will explain why and what your options are, including how to get through the next day or two.

Problems we solve most often

AC stops working in extreme heat

Failed capacitors, contactors, compressors and refrigerant loss are the usual culprits. We diagnose on site and explain what the repair involves.

Furnace or heat pump producing no heat

Ignition faults, flame sensors, blower failures and control board problems all show up on cold nights. We handle heating emergencies too.

Sudden total system shutdown

Tripped breakers, blown fuses, failed transformers and safety switch lockouts. We find the fault rather than just resetting it.

Emergency service across the Las Vegas valley

We respond throughout Las Vegas, Henderson, Summerlin, North Las Vegas and surrounding areas. Summer is our busiest season by a wide margin, so calling as soon as the system fails, rather than waiting to see if it recovers, gives you more scheduling options.

Frequently asked questions

Yes, we take emergency HVAC calls around the clock. How quickly a technician can get to you depends on the failure and how many emergency calls are already in progress, so call and describe the situation and we will give you an honest answer about timing.
