Emergency AC Repair in Chicago, IL
AC quit during a heat wave? 24/7 emergency cooling repair with same-day dispatch to get your home safe again fast.
When your air conditioner dies during a Chicago heat wave, indoor temperatures can climb into dangerous territory fast — a real health risk for older adults, young children, and anyone with a medical condition. Polar Refrigeration & Air Control provides 24/7 emergency AC repair across Chicago and the suburbs, with same-day dispatch whenever the weather and our schedule allow.
Our emergency technicians carry the parts behind most sudden cooling failures — capacitors, contactors, fan motors, and the tools to diagnose refrigerant and airflow problems — so a large share of calls are solved on the first visit. We give you upfront pricing before any work starts.
If your home is dangerously hot and you have vulnerable residents, tell us when you call. We prioritize those situations, and we can offer guidance on staying safe until we arrive.
Safety first
If you smell gas, see smoke, or suspect carbon monoxide, leave your home immediately and call 911 or your gas utility first — then call us at (831) 461-3437.
AC Emergencies We Respond To
- The AC has completely stopped and the home is overheating
- Warm air only, during a heat advisory
- The outdoor unit hums but won't start (often a capacitor)
- Burning or electrical smell from the system
- The breaker keeps tripping when the AC runs
- A frozen system leaving you with no cooling
- Water flooding from the air handler or furnace
Why AC Fails During Heat Waves
Air conditioners fail during heat waves for a simple reason: that's when they work hardest. A marginal capacitor, a weak contactor, low refrigerant, or a dirty condenser coil that struggled along on mild days finally gives out under peak load. Extended run times also freeze coils when airflow is restricted by a dirty filter.
Because these failures cluster on the hottest days, we staff up for summer emergencies and carry the common parts. Fast, correct diagnosis is what separates a same-day fix from days without cooling.
- Failed run capacitors and contactors
- Refrigerant loss from leaks
- Frozen evaporator coils from airflow restriction
- Fan and blower motor failures
- Tripped breakers and electrical faults
Staying Safe Until We Arrive
If your home is dangerously hot, move to the lowest, shadiest level, close blinds against direct sun, run fans, and stay hydrated. Check on elderly neighbors and anyone with health conditions. If someone shows signs of heat illness, treat it as a medical emergency and call 911. Let us know the situation when you call so we can prioritize appropriately.
Our Emergency AC Response
24/7 answer & triage
We pick up around the clock, assess how urgent your situation is, and commit to a 60-minute call-back with a dispatch window.
Same-day dispatch
A technician heads out equipped for the most common cooling failures, prioritizing homes with vulnerable residents during heat advisories.

Verify cooling
We confirm proper temperature split and airflow so your home is actually cooling before we leave.
What Affects the Cost
Emergency AC repair is quoted upfront before work begins. These factors shape the cost.
Time of call
Nights, weekends, and holidays carry an after-hours premium over scheduled service.
The failed component
A capacitor is inexpensive; a compressor or coil repair is a major job. Diagnosis determines the category.
Refrigerant needs
Leak repair and recharge — especially on older R-22 systems — adds to the cost.
Access and conditions
Rooftop, high-rise, and tight-lot units take more time than a standard ground-level condenser.
