When the summer heat peaks in East Tennessee, the last thing you want is for your air conditioner to break down unexpectedly. Unfortunately, AC failures often happen at the worst possible times — during heatwaves or busy weekends when HVAC technicians are in high demand. Knowing what to do during an AC emergency can save you time, money, and discomfort. At Advanced Heat, AC & Plumbing, we specialize in emergency HVAC services across East TN to keep your home cool and your family safe when you need it most.

Let’s walk through what you should do when your AC suddenly stops working, how to assess the situation, and when to call the pros.

Common Causes of Air Conditioner Breakdowns

Before you panic, it’s helpful to understand the typical reasons why air conditioners fail, especially during the summer months in East TN:

  • Clogged Air Filters: A dirty filter restricts airflow and forces your system to work harder, leading to overheating.
  • Refrigerant Leaks: Low refrigerant levels cause your AC to lose cooling efficiency.
  • Electrical Failures: Capacitor or breaker issues can cause sudden shutdowns.
  • Frozen Evaporator Coils: Poor airflow or low refrigerant can cause the coils to freeze, halting the cooling process.
  • Thermostat Malfunctions: Incorrect readings or dead batteries can make the system appear broken.
  • Blocked Condensate Drain Line: A clogged drain can cause the system to shut off to prevent water damage.

Understanding these issues can help you troubleshoot quickly.

Step 1: Check Basic Components Before Calling for Emergency AC Repair

When your AC stops working, try these basic troubleshooting steps:

✅ Check the Thermostat

Make sure the thermostat is set to “cool” and that the temperature setting is lower than the current room temperature. If it’s battery-operated, try replacing the batteries.

✅ Inspect the Circuit Breaker

Sometimes, the circuit breaker may trip due to a power surge or system overload. Check your breaker box and reset any tripped switches.

✅ Examine the Air Filter

A severely clogged filter can restrict airflow and even cause the system to shut down. If the filter is dirty, replace it immediately.

✅ Look for Ice Build-Up

Inspect the AC unit’s coils for ice. If you see ice accumulation, turn off the system and let it thaw. Running the system with frozen coils can cause severe damage.

If these quick fixes don’t restore your cooling, it’s time to call Advanced Heat, AC & Plumbing for emergency AC repair.

Step 2: Know When It’s a True HVAC Emergency

Not every AC issue qualifies as an emergency. Here's when you should seek immediate help:

  • Complete System Failure: When the AC won’t turn on despite trying all basic troubleshooting steps.
  • Unusual Sounds: Grinding, screeching, or banging noises indicate mechanical failure.
  • Burning Smell or Smoke: This can signal an electrical issue that could become a fire hazard.
  • Refrigerant Leaks: These can be dangerous to your health and harmful to the environment.
  • Severe Water Leaks: A clogged condensate line can overflow and damage your home.

If you experience any of these symptoms, call Advanced Heat, AC & Plumbing’s emergency HVAC team immediately.

Step 3: Stay Safe and Minimize Heat Exposure

While waiting for the repair technician, take these steps to keep your family comfortable and safe:

  • Use Fans: Circulate air with ceiling or box fans to help with immediate cooling.
  • Close Curtains: Block direct sunlight to keep indoor temperatures lower.
  • Stay Hydrated: Drink plenty of water to prevent heat-related health issues.
  • Relocate if Needed: If indoor temperatures become dangerously high, especially for children, pets, or elderly family members, consider moving to a cooler location temporarily.
