⚠️ HVAC Emergency? Stay Calm and Follow These Steps
When your heating or cooling system fails unexpectedly, knowing what to do in the first few minutes can prevent further damage, save money on repairs, and help you get service faster.
Your HVAC system failing is never convenient, but it always seems to happen at the worst possible time—during a Texas heat wave, a surprise cold front, or late at night when service calls are most expensive. While you wait for professional help, there are several important steps you can take to protect your system and potentially solve the problem yourself.
Step 1: Ensure Safety First
🚨 Safety Warning - Stop Immediately If You Notice:
- Burning smells or visible smoke - Turn off system and call fire department if necessary
- Gas odors - Leave immediately, call gas company from outside
- Electrical sparks or buzzing - Turn off power at breaker panel
- Water leaking near electrical components - Turn off power before investigating
- Carbon monoxide alarm - Evacuate immediately, call 911
If none of these dangerous conditions exist, proceed with the troubleshooting steps below.
Step 2: Basic System Assessment
Check the Thermostat
Verify the thermostat is set to the correct mode (heat/cool/auto) and temperature. Check if the display is working—dead batteries are a common culprit. Try adjusting the temperature 5 degrees to see if the system responds.
Examine the Air Filter
A severely clogged filter can cause system shutdown for protection. If the filter is visibly dirty or hasn't been changed in months, replace it immediately. This alone resolves many "emergency" service calls.
Check Circuit Breakers
Look at your electrical panel for tripped breakers. HVAC systems typically have separate breakers for indoor and outdoor units. Reset any tripped breakers by turning them fully off, then back on.
Inspect the Outdoor Unit
Check for obvious obstructions like debris, leaves, or ice buildup. Ensure the disconnect switch near the unit is in the "ON" position. Look for any visible damage to the unit or refrigerant lines.
Listen and Observe
Note any unusual sounds (grinding, squealing, clicking), smells (burning, musty, chemical), or visible issues (ice, water leaks, unusual vibration). This information helps technicians diagnose problems faster.
Quick Troubleshooting Checklist
Before Calling for Service, Verify:
Common Texas HVAC Emergencies and Solutions
Summer Cooling Failures
Problem: AC running but not cooling during 100°F+ days
Common Causes:
- Frozen evaporator coil (turn off system, let thaw 2-4 hours)
- Dirty outdoor condenser coil (gently clean with hose)
- Low refrigerant (requires professional service)
- Clogged air filter restricting airflow
Winter Heating Failures
Problem: No heat during unexpected Texas cold fronts
Common Causes:
- Heat pump ice buildup (normal during defrost cycle)
- Gas supply issues (check other gas appliances)
- Ignition problems (pilot light or electronic ignition)
- Thermostat incorrectly set to emergency heat
Complete System Failure
Problem: No response from heating or cooling
Check First:
- Electrical power at panel and disconnect switches
- Thermostat power and settings
- Emergency shutoff switches (often near furnace)
- GFCI outlets that may have tripped
When to Call for Emergency Service Immediately
- Safety hazards: Gas leaks, electrical sparks, carbon monoxide alarms
- System damage: Water leaks, unusual noises, visible damage
- Extreme weather: Temperatures above 95°F or below 35°F with no heating/cooling
- Health concerns: Family members with medical conditions affected by temperature
- Troubleshooting failed: Basic steps didn't resolve the issue
What NOT to Do During an HVAC Emergency
- Don't ignore safety warnings - Strange smells, sounds, or sights require immediate attention
- Don't repeatedly restart the system - This can cause additional damage
- Don't adjust internal components - Leave repairs to qualified technicians
- Don't use alternative heating/cooling unsafely - Space heaters and generators require proper ventilation
- Don't force stuck switches or components - You could worsen the problem
Temporary Comfort Solutions
While waiting for repairs, these strategies can help maintain comfort:
Cooling Emergencies
- Close blinds and curtains to block sunlight
- Use fans to circulate air and create wind-chill effect
- Stay hydrated and wear light, loose clothing
- Limit heat-generating activities (cooking, laundry)
- Create cross-ventilation by opening windows if outdoor temperature drops
Heating Emergencies
- Layer clothing and use blankets
- Gather family in one room to share body heat
- Open curtains on sunny windows during the day
- Use safe backup heating (ensure proper ventilation)
- Protect pipes from freezing with cabinet doors open
