Emergency HVAC Repair: What to Do Before You Call
When your furnace fails during a freezing night or your air conditioner shuts down in summer heat, immediate action can prevent safety hazards and costly damage. As Vancouver's 24/7 emergency HVAC service leader, Equinox HVAC has responded to hundreds of emergency calls. Based on our field experience, here's exactly what homeowners should do before technicians arrive.
Safety First: Critical Immediate Actions
Check for Gas Leaks: If you smell rotten eggs or gas, this is a life-threatening emergency. Evacuate immediately, call 911 from outside, and contact your gas provider. Do not use electrical switches or light any flames inside. Gas leaks can cause explosions and carbon monoxide poisoning—only emergency responders should handle this.
Carbon Monoxide Alarm: If your CO detector sounds, evacuate your home immediately and call 911 from outside. Carbon monoxide is invisible and odorless but deadly. Don't re-enter until professionals give clearance.
Burning Smells or Smoke: Shut down your system, turn off power at the circuit breaker, and call emergency services. These indicate potential electrical fire hazards.
Actionable Troubleshooting You Can Do
Check Your Thermostat Settings: This solves approximately 30% of emergency calls we receive. Verify the mode is set to "Heat" in winter or "Cool" in summer. Confirm the temperature setting is several degrees from current room temperature. If your thermostat has dead batteries, replace them immediately with the correct type (usually AA or AAA). Wait 30 seconds for the system to reset before adjusting temperature again.
Reset Your Circuit Breaker: Locate your electrical panel and find the breaker labeled "HVAC" or "Furnace." If it's in the OFF position or between ON and OFF, it's tripped. Switch it fully OFF, wait 10 seconds, then flip it back ON. Listen for your system to restart. If the breaker trips again immediately, leave it OFF—this indicates an electrical problem requiring professional diagnosis. Don't repeatedly reset a tripping breaker, as this can cause equipment damage.
Inspect Your Air Filter: A clogged filter restricts airflow and forces your system to shut down as a safety measure. Locate your filter (usually near the furnace or in a return air vent). Hold it up to light—if you barely see light through it, it needs replacement. Purchase the same size (typically 16x25x1, 16x25x4, or 20x25x1) and install it with the arrow pointing toward the furnace. This simple fix resolves heating and cooling problems in many cases. Replace or clean filters every 1-3 months.
Clear Blocked Vents: Walk through your home and ensure all supply vents and return air grilles are unobstructed. Move furniture, curtains, and storage items blocking vents. Clean visible dust from registers with a dry cloth. For outdoor AC units, remove leaves, debris, and snow blocking the condenser. Restricted airflow makes systems seem non-functional even when operating properly.
Complete System Reset: Turn off your thermostat, switch OFF the circuit breaker, wait 5 minutes, switch the breaker back ON, and turn the thermostat on. Set your desired temperature and wait 30 minutes. This power cycle often clears internal errors.
What NOT to Attempt
Never attempt gas line repairs, refrigerant handling, electrical component work, or opening sealed HVAC components yourself. These require EPA certification, specialized training, and proper equipment. Mistakes create safety hazards and void equipment warranties.
Avoid repeatedly cycling the system on and off, setting extreme thermostat temperatures, or using duct tape as a temporary fix. These damage components and create fire hazards. Don't use space heaters near your furnace—maintain at least 3 feet clearance and never leave portable heaters unattended.
Minimize Damage While Waiting
For Heating Emergencies: Layer up with sweaters and thermal clothing. Close off unused rooms to concentrate warmth. Use electric space heaters safely (away from flammable materials). Insulate windows with closed curtains. Critically, wrap exposed water pipes in insulation or blankets—frozen pipes burst within hours and cause thousands in water damage. Keep basement doors slightly open to allow furnace heat circulation.
For Cooling Emergencies: Close blinds and curtains to block solar heat. Use fans positioned near outward-facing windows to push hot air outside. Stay hydrated and avoid using heat-generating appliances. Basements stay naturally cooler—move there if possible. Open windows at night if outdoor temperatures drop below indoor levels.
Prepare for Technician Arrival
Clear pathways to your furnace, air handler, and outdoor units. Ensure thermostat accessibility. Have your system's model number and serial number ready. Know where main electrical panels and HVAC shut-off switches are located. Secure pets in a separate area. Be present to answer questions about when problems started and any unusual noises or smells you noticed.

Prevention: The Best Strategy
Schedule annual furnace inspections every fall and pre-summer AC checks in spring. Replace air filters every 1-3 months. Maintain 3 feet of clearance around all HVAC equipment. Install and test carbon monoxide detectors monthly. Watch for early warning signs: performance changes, unusual noises, strange smells, or unexplained energy bill increases. Catching these early prevents costly emergencies.
Summary
HVAC emergencies are stressful, but systematic action protects your family and home. Prioritize safety by evacuating if you smell gas or see fire. Check simple solutions first—thermostat settings, circuit breakers, filters, and vents. Know your limits and don't attempt professional-grade repairs.
