Emergency Call Protocol

Emergency Call Protocol for HVAC Technicians

When you do HVAC, “emergency” can mean anything from a dead AC in a July heatwave to a carbon monoxide alarm at 2 a.m. This protocol gives you a clear definition of what counts as an emergency, a fast triage script your dispatcher (or AI receptionist) can run, and a repeatable after-hours plan that protects safety, time, and profit. Use it to stop the chaos on the first 95°F day or the first 15°F night—and to prevent “false emergencies” from wrecking your schedule.

1) What Counts as an HVAC Emergency (and What Doesn’t)

Use these categories to decide if you roll a truck now or book the next available slot. The goal is simple: respond fast to safety and extreme-temp risk, but don’t let routine repairs get labeled “emergency” just because the customer is stressed. Category A — Life/Safety (Immediate): carbon monoxide (CO) alarm, gas smell, smoke/burning smell, electrical burning, visible arcing, melting wires, refrigerant leak in a tight space (nausea/dizziness), someone passed out or has symptoms, or a commercial unit causing a safety shutdown in an occupied space. These are “stop and make safe” calls. Category B — No Cooling/No Heat in Extreme Conditions (Same-day if possible): AC down during heat advisory/heatwave (especially with babies, elderly, medical conditions), furnace/boiler/heat pump down in freezing temps, or a home sitting above 85°F inside or below 55°F inside. Include “system short-cycling and won’t stay on,” “breaker keeps tripping,” or “unit froze into a solid block of ice and won’t cool.” Category C — Water Damage/Property Risk (Urgent): ceiling stain or water dripping from a return, condensate overflow, clogged drain causing pan overflow, frozen coil thawing and flooding, rooftop package unit leaking into tenant space. Not an emergency (schedule): tune-ups, noisy-but-working units, “my bill is high,” weak airflow that’s still cooling/heating, “second floor is warmer,” thermostat upgrades, ductwork estimates, and full system replacement quotes ($6,000–$15,000) unless you have a safety issue. These should be booked as standard service, not after-hours.

Frequently Asked Questions

If a customer says “CO detector is chirping,” is that an emergency?

Treat it as an emergency until you know it’s a low-battery chirp. Ask: “Does it say ‘FAULT’ or ‘END’ or is it a steady alarm?” If it’s alarming or anyone feels sick, tell them to leave and call 911/gas utility. If it’s a single chirp every minute and no symptoms, it may be battery/end-of-life—still recommend they follow the detector instructions and schedule a furnace safety check.

What’s the fastest way to tell “no cool” vs “not keeping up”?

Ask two things: “Is the outdoor unit running (fan spinning and humming)?” and “What’s the indoor temperature right now versus the thermostat setpoint?” Total no-cool usually means not running at all, breaker trip, bad capacitor/contactor, or safety lockout. “Not keeping up” often points to airflow (dirty filter/coil) or refrigerant issues.

Should you dispatch after-hours for a frozen coil?

Usually no if there’s no extreme indoor temperature or medical risk. Tell them to turn COOL off and FAN on to thaw, replace the filter, and book the next available slot. Dispatch after-hours only if indoor temps are unsafe or there’s risk of water damage when it thaws.

How do you prevent customers from labeling everything an emergency?

Set a clear rule: safety issues, active water leaks, and extreme-temp outages qualify. Quote the emergency diagnostic fee upfront; many “false emergencies” choose a scheduled slot when they hear after-hours pricing. Offer the next available appointment window and send it by text so they feel taken care of.

What do you do when you can’t answer because you’re handling refrigerant or working in a 140°F attic?

Route calls to a system that can triage and capture details, then send you a summary (address, issue, urgency, photos). That way you can finish the recovery/charge safely and return calls in batches without losing the customer to the next HVAC company.

How do you handle emergency pricing without sticker shock?

Be direct and consistent: state the after-hours diagnostic/dispatch fee first, then give realistic repair ranges ($200–$800 AC, $200–$600 heat) and explain it depends on parts and diagnosis. Customers accept emergency pricing more easily when they understand you’re sending an on-call tech immediately and you’re transparent before you roll.
