 What Counts as an HVAC Emergency?

Not every HVAC issue is a true emergency—but some situations should be treated as urgent, especially when safety, extreme temperatures, or potential property damage are involved. Common HVAC emergencies include:

• No heat during cold weather

• No cooling during extreme heat

• Burning smell, smoke, or electrical odor

• Carbon monoxide (CO) alarm or suspected venting issue

• Significant water leaks that could damage ceilings, floors, or electrical components

• Repeated breaker trips when the system starts

• Loud mechanical noises that suggest a failing motor or blower
  If you’re unsure, call—an emergency visit may prevent additional damage.

If you suspect a safety issue, prioritize safety first. Here are a few safe steps you can take while waiting for service:

• If you smell burning or see smoke: turn the system off at the thermostat; if safe, shut off power at the breaker.

• If a CO alarm is sounding: leave the home immediately and contact emergency services.

• If you see water leaking: turn the system off and contain the leak with towels/buckets; avoid standing water near electrical components.

• If the AC is not cooling and you see ice: turn cooling off and run the fan to help thaw, then call for service.

• If you have no heat: confirm thermostat settings and power, then call us if the system still won’t run
