Emergency HVAC FAQs

What constitutes an HVAC emergency?

HVAC emergencies include: complete system failure during extreme temperatures (heat over 90°F or cold under 40°F), gas leaks or smells, burning smells or smoke, electrical issues like sparking, refrigerant leaks with hissing sounds, and water leaks causing property damage. These situations can be dangerous and require immediate professional attention.

How much does emergency HVAC service cost?

Emergency HVAC service typically costs 1.5-3x normal rates. After-hours calls (nights/weekends) usually run $150-$250 for the service call plus parts and labor. Holiday rates can be higher. Many companies charge $100-$200 diagnostic fees for emergency calls, applied to the total repair cost.

How is commercial HVAC different from residential?

Commercial HVAC systems are larger, more complex, and designed for different usage patterns. They often use rooftop units (RTUs), chillers, and complex ductwork systems. Commercial systems require specialized zoning, higher capacity, and must meet different building codes. They also need more frequent maintenance due to constant operation and typically have different efficiency requirements.

Why is my AC unit freezing up?

Air conditioners freeze due to: restricted airflow from dirty filters or blocked vents, low refrigerant levels, dirty evaporator coils, or malfunctioning blower motors. Turn off your AC immediately if you notice ice buildup and allow it to thaw completely before calling a technician to diagnose the underlying cause.
