Every emergency HVAC situation we respond to across California
AC failures, heating emergencies, and water damage from HVAC systems all require immediate attention — but each situation is different and each one gets worse with every hour it goes unaddressed.
Complete AC system failure — no cooling
System runs but produces no cool air, or won’t turn on at all. Most common causes: failed capacitor, failed contactor, compressor failure, or complete refrigerant loss.
AC running constantly — home won’t cool down
System runs all day but can’t reach the set temperature — common in Fresno and Bakersfield when temps exceed 110°F. Causes include low refrigerant, dirty condenser coil, or an undersized system pushed past its capacity.
Ice forming on the AC unit
Ice on the evaporator coil or refrigerant lines signals low refrigerant or restricted airflow. Turn the system off immediately — running a frozen system damages the compressor rapidly.
AC tripping the circuit breaker repeatedly
A system that trips the breaker when it tries to start has an electrical fault — usually a failed capacitor, a failing compressor drawing excess amperage, or a wiring issue. Do not keep resetting the breaker. Each reset attempt with an electrical fault risks damaging the compressor further.
Furnace not producing heat
Furnace failures include igniter failure, gas valve issues, flame sensor fouling, and heat exchanger cracks. Carbon monoxide safety is assessed on every furnace emergency call.
Carbon monoxide concern — furnace
If your CO detector has alarmed or you smell gas near your furnace — leave the building immediately and call 911 first. Once the building is cleared, call Grandmark. A cracked heat exchanger in a gas furnace is a life-safety issue. We assess every furnace emergency call for CO risk as standard procedure.
Unusual noises — grinding, banging, squealing
Mechanical noises from an HVAC system are not something to ignore and monitor. Grinding is bearing failure. Banging is a loose component or failed part inside the system. Squealing is a belt or motor bearing.
Water leaking from HVAC system
Water pooling under your air handler or dripping from ducts means the condensate drain system has failed. Water accumulation inside an air handler creates mold growth conditions within 24–48 hours in California’s climate. It also activates safety shutoffs that cut cooling entirely.
What happens when an HVAC emergency goes unaddressed in California’s heat
Every hour of delay in a California summer HVAC emergency costs more than the hour before it. Here’s what the timeline actually looks like.
1-6 HOURS
Indoor temperatures climb to 85–95°F within the first few hours of AC failure in California’s heat. Manageable for most healthy adults initially but heat stress risk increases significantly for elderly residents, young children, pets, and anyone with cardiovascular or respiratory conditions. By hour 6, the situation has moved from uncomfortable to dangerous.
6-24 hOURS
A failed capacitor or low refrigerant situation — if the system is still attempting to run — causes progressive compressor damage during this window. A $300 capacitor repair becomes a $2,500 compressor replacement if the system continues to struggle through multiple start attempts.
24-48 HOURS
For water-related failures, mold growth conditions develop within 24–48 hours in California’s climate. For complete system failures, continued operation in extreme heat accelerates damage to other system components beyond the original failure point.
1 week
A delayed repair that progressed to compressor failure now requires a full system replacement — at emergency pricing, with 1–2 week equipment lead times in peak season. What started as a $300–$800 repair is now a $6,000–$12,000 replacement on an emergency timeline.
