Signs of an AC Emergency

Some AC problems can wait for standard AC repair. A few can't. Weak cooling in a comfortable house can wait for morning, but the signs below mean it's time to call now.

Outdoor AC unit that won't turn on

AC won't turn on

The system is unresponsive when it should be cooling. Common causes are a tripped breaker, a thermostat setting issue, a failed capacitor, or a failing compressor. A breaker that trips repeatedly means there's a short, a bad capacitor, or a compressor problem. Frostline finds which one instead of just resetting it.

Home AC blowing warm air and not cooling

AC blowing warm air or not cooling

The fan runs but the air isn't cold. Usually low refrigerant from a leak, a frozen coil, or a failing compressor. In a Florida heat wave the house heats up fast, which makes this an emergency.

Evaporator coil in an indoor AC unit, where ice forms

AC frozen or iced over

Ice on the coil or refrigerant lines stops cooling and puts the compressor at risk. Running a frozen system can flood the compressor with liquid refrigerant (liquid slugging) and damage it. The system should be shut off until a technician arrives.

Water leaking and pooling around an indoor AC unit

AC leaking water or pooling

Water at the indoor unit, on the floor, or on a ceiling usually means a clogged condensate drain line. On most systems a float safety switch trips and shuts the AC down to prevent flooding, which is why a leaking AC sometimes won't turn on. Left alone, the leak causes drywall and mold damage.

Technician checking an AC after a burning smell from the unit

Burning or hot-plastic smell

A burning or melting-plastic smell indicates an electrical fault, typically overheating wiring or a failing motor. The system should be shut off at the thermostat and the breaker before a technician arrives. Running it risks a fire.

Emergency AC Repairs We Handle

These are the failures behind most after-hours and 24-hour emergency calls. Common parts are stocked on every service truck, so most are completed on the first visit.

Capacitor & Electrical Repair

The capacitor gives the compressor and fan motor the jolt they need to start. When an AC won't turn on, the cause is usually a failed capacitor, a burned contactor, or a tripped breaker, not the full system. Capacitor replacement is the most common emergency repair and is typically a same-night fix. When a breaker trips repeatedly, Frostline locates the short or the failing component rather than resetting it.

Refrigerant Leak Repair

AC blowing warm air usually means refrigerant is low, and low refrigerant means a leak. Frostline locates the leak, seals it, and recharges the system to spec. A simple top-off bleeds back out within a week. Running low on refrigerant causes the compressor to overheat, so Frostline addresses these calls quickly.

Frozen Coil & Compressor Protection

Ice on the coil restricts airflow and puts the compressor at risk. Compressors are built to pump gas, not liquid, so a frozen coil can cause liquid refrigerant to slug back into the compressor and damage it. Frostline thaws the system, identifies the airflow or refrigerant cause, and protects the compressor before failure.

Drain Line & Water Damage Prevention

A clogged condensate drain line backs water into the pan, then onto the floor or into a ceiling below. On most systems a float safety switch trips and shuts the AC off to prevent flooding, which is one reason a leaking AC sometimes won't turn on at all. Frostline performs drain line cleaning, tests the float switch, and confirms the system drains correctly.

Electrical Diagnosis & Shutdown

A burning smell, visible sparking, or a breaker that won't reset is an electrical hazard. Frostline shuts the system down safely, isolates the fault, and keeps the system off until the fault is fixed.

Our Process

How Emergency AC Repair Works

1

Call Frostline

Frostline answers 24/7 and dispatches a technician the same day when possible. Describe what the AC is doing when you call.

2

Phone guidance and dispatch

While the technician is en route, you get over-the-phone guidance. If there's something safe to do in the meantime, like shutting off a frozen unit or killing a smoking breaker, Frostline walks through it on the call.

3

Diagnosis and upfront price

On arrival, the technician inspects the system, finds the cause, and gives the full price before any work begins.

4

Repair completed on the same visit

Most emergency repairs are finished on the first visit. Common parts are stocked on every service truck, and the technician tests the system before leaving.

Emergency AC Repair Questions

Answers to the questions homeowners ask most during an AC emergency.

Is a broken AC an emergency?

It depends on the situation. If the home isn't cooling and the temperature is in the 90s, that qualifies as an emergency. A burning smell, water leaking from the unit, or a frozen AC also count as emergencies, since each gets worse the longer the system runs. Weak airflow or slow cooling in a comfortable home usually can wait for standard AC repair.

My AC won't turn on. What should I check?

Start at the thermostat: set it to COOL, several degrees below room temperature, with fresh batteries. Then check the breaker and reset it once. If the breaker trips again, leave it off. A breaker that won't reset points to a short, a failed capacitor, or a compressor problem. Also check the disconnect box at the outdoor unit and the air filter, since a heavily clogged filter can shut the system down. If none of that restores operation, the system needs a technician.

AC is blowing warm air. Is that an emergency?

In a Florida heat wave, usually yes. Warm air means the system isn't cooling, which is typically low refrigerant from a leak, a frozen coil, or a failing compressor. The home heats up quickly in these conditions, making it an emergency call. Frostline diagnoses the actual cause rather than topping off refrigerant that will leak back out within days.

Should I keep running the AC until morning?

If the system is frozen or blowing warm, no. Running a failing AC can turn a small repair into a full compressor replacement, and a frozen coil can flood the compressor with liquid refrigerant and finish it off. Also avoid rapidly cycling the system on and off. This is the 3-minute rule: a compressor needs several minutes for internal pressures to equalize before restarting, or it overheats. Most thermostats build that delay in. If the home is comfortable and the cooling is only slow, the repair can wait for a daytime visit.

How fast can Frostline get there?

Frostline answers 24/7 and dispatches a technician as quickly as possible, same-day on most calls, including evenings, weekends, and after-hours. When you call, Frostline provides a realistic arrival window.

What should I do while waiting for the technician?

Shut the AC off if it is frozen, leaking water, or smells like burning. Running it makes the damage worse. Close blinds against direct sunlight, run fans for air circulation, and stay hydrated.

My AC is old. Should I repair or replace it?

Even during an emergency call, Frostline provides the repair-versus-replace math. Two rules apply: the $5,000 rule (multiply the unit's age by the repair cost; if the total exceeds $5,000, replacement should be considered) and the 50% rule (if a single repair costs more than half the price of a new system, it's time to look at AC replacement). A 12-year-old unit needing a significant repair typically clears both thresholds. Frostline provides the numbers and lets the homeowner decide.
