Call dispatch tonight? Or wait?
Eight symptom questions. Three branches. Routes to call dispatch tonight, wait until morning, or try this one fix first. Built from real after-hours dispatch logic — saves you overtime when you can wait, gets you on the truck fast when you can't.
How we route an after-hours call.
Every after-hours AC call goes through the same three filters before we put a truck on the road. The tool above runs the same filters in the same order.
Filter 1 — Hard triggers
Burning smell, tripped breaker, active water damage, or medically heat-sensitive occupants in the house. Any of these is a call-now dispatch regardless of what the rest of the system is doing. The CDC's extreme-heat guidance identifies elderly, infants, and people with chronic conditions as high-risk groups whose comfort failures escalate to safety failures fast in Birmingham summer conditions.
Filter 2 — Comfort vs safety
Comfort failures (warm air, mild cooling loss, intermittent short-cycling) wait until morning. The system survives the night on fan-only mode. The technician arrives with a stocked truck instead of three hardware-store stops. The bill is half what after-hours dispatch costs.
Filter 3 — DIY-checkable
Some symptoms — blank thermostat, blown disconnect, choked filter, tripped float switch — are three-minute homeowner fixes. We route you there first because (a) it saves you a service call, (b) it saves us a dispatch, and (c) if the DIY fix doesn't work, the technician now has diagnostic information that speeds the morning call.
Source standards
Triage logic follows ACCA service standards for residential dispatch prioritization, and OSHA heat-exposure thresholds for occupant-safety escalation. The R-454B refrigerant transition guidance from U.S. EPA SNAP affects new installs but not emergency-repair triage.
Five-step process.
Stop and breathe
If anyone in the house is elderly, infant, or has a heart/respiratory/autoimmune condition, skip straight to calling dispatch. Don't troubleshoot through heat exposure.
Check for hard triggers
Burning smell, smoke, tripped breaker, water actively damaging drywall — these are call-now no matter what else the system is doing.
Answer the symptom questions
Each question is yes or no. The tool weights your answers against dispatch logic we use on real after-hours calls.
Read the verdict
Three branches: call dispatch tonight, wait until morning and book a slot, or try one DIY check first. Each comes with specific next-step actions.
Document what you tried
If you call dispatch, screenshot this verdict or note your answers. Saves diagnostic time on the truck.
Three services for the three branches.
Emergency AC Repair
24/7 east-corridor dispatch for true after-hours emergencies. Licensed Alabama HVAC, NATE-certified.
Same-Day AC Repair
Morning dispatch for the comfort failures the triage says can wait. Stocked truck, scheduled window.
Preventive Maintenance
The triage tool wouldn't exist if every system got a spring tune-up. Catch the failures before they become 2 AM calls.
Triage questions, answered straight.
When is an AC problem a real emergency?+
An AC failure becomes an emergency when (1) someone in the house is medically heat-sensitive — elderly, infant, or has a heart, respiratory, or autoimmune condition, (2) there is electrical evidence of failure like a tripped breaker, burning smell, or sparks, or (3) water is actively damaging drywall or ceilings from a condensate overflow. Comfort failures — warm but running, mildly cool, slow cooling — are not emergencies. They are next-morning dispatch.
Should I reset a tripped breaker on my AC?+
Once, carefully. If it trips again immediately, do not reset it a second time. A breaker that trips twice means the load on the circuit exceeds what the wire can carry — usually a shorted compressor winding, a stuck contactor, or a failed start capacitor. Resetting again can melt insulation and start a fire. Shut the system off at the disconnect and call dispatch.
My thermostat is blank. Is that an emergency?+
Almost never. The most common cause is dead batteries (most digital thermostats run on AA or AAA cells behind the faceplate). Second most common is a tripped float switch — a small plastic switch in the drain pan that kills the system when the condensate drain backs up. Third is a tripped indoor disconnect at the air handler. None of those are after-hours emergencies. Try them in order.
There is ice on my outdoor unit. Should I call right now?+
Ice on the outdoor lineset usually means the indoor coil is frozen. Shut the system off, switch to fan-only at the thermostat, and let it thaw — usually 2-4 hours. After it thaws, replace the air filter and check that the supply registers aren't closed. If the unit refreezes within 24 hours of thaw and filter change, that is a refrigerant-charge issue and needs a technician. Not an after-hours call unless heat-sensitive occupants.
Water is dripping from my indoor unit. How bad is it?+
Water = clogged condensate drain. The pan under the indoor coil fills, overflows, and damages drywall, ceiling tile, or flooring. Shut the system off, put a bucket under the drain, and call in the morning unless drywall damage is actively spreading. Quick DIY: take a wet/dry vacuum to the white PVC drain stub outside (next to the outdoor unit). Two minutes of suction clears most clogs.
Why is the system running but the house is not cooling?+
Three common causes, in order of likelihood: (1) refrigerant undercharge from a slow leak — needs a leak-search and recharge, technician work; (2) failed capacitor on the outdoor unit — the compressor or fan won't start under load; (3) failed contactor — same symptom as a bad capacitor. All three are next-morning calls unless medically heat-sensitive occupants are home.
What does "after-hours" cost vs morning dispatch?+
After-hours dispatch — 6 PM to 8 AM, weekends, holidays — runs at overtime rate for the technician and at limited parts availability since suppliers are closed. We do not publish flat numbers (every house is different), but routine repairs done at 11 PM cost noticeably more than the same repair done at 9 AM Monday. The triage tool above exists to keep you from paying overtime for a fix that can wait six hours.
Dispatch is open 24/7.
