How Much Does Emergency AC Repair Cost?
An emergency AC repair call with Galaxy Heating & Air Conditioning typically costs $250 to $1,500, depending on the problem. Sometimes the repair is easy and obvious — a filter needs to be changed or a capacitor needs to be replaced. Our phones are answered by a real person 24/7 and technicians are dispatched as soon as possible. We don't charge extra for weekends or morning/evening calls, and the diagnostic fee is always the same.

What Counts as an HVAC Emergency?
Any of these situations qualifies for our 24/7 emergency dispatch. Don't wait until business hours — call us now.
No Heat in Winter
Temperatures below 50°F indoors are a health risk. We treat no-heat calls as top priority, especially for households with elderly residents or young children.
No AC During Heat Wave
When outdoor temps exceed 90°F, a failed AC becomes a medical emergency. We prioritize cooling calls during PG&E heat advisories and extreme heat events.
Gas or Burning Smell
A sulfur or burning smell from your furnace or HVAC system requires immediate attention. Turn off your gas supply and call us — do not wait.
Ice on AC or Heat Pump
A frozen evaporator coil or outdoor unit indicates a refrigerant leak or airflow failure. Running the system while frozen can destroy the compressor.
Complete System Failure
Thermostat showing no response, system won't turn on, or breaker keeps tripping — these are total failures requiring same-day diagnosis.
Water Leak from HVAC
A backed-up condensate drain or cracked heat exchanger can flood your home. Shut off the system and call us immediately to prevent structural damage.

Emergency HVAC FAQ
Do you really answer calls 24/7?
Yes — a real person answers our line any time you call, day or night, including weekends and holidays. You will never reach voicemail or an automated system. Call (925) 578-3379 at any hour.
What counts as an HVAC emergency?
No heat when it's below 50°F, no AC during a heat wave above 90°F, a gas smell from your furnace, ice on your AC unit, a failed heat pump, flooding from a condensate line, or any complete system failure.
How quickly will a technician arrive?
We dispatch technicians as soon as one is available. For calls received during business hours, we aim to respond that same day. For overnight calls, we prioritize you for the earliest available appointment — typically first thing in the morning.
Is emergency service more expensive?
No. Galaxy does not charge extra for weekend, early morning, or evening calls, and the diagnostic fee is always the same regardless of when you call. A typical emergency AC repair runs $250 to $1,500 depending on the problem, and we give you a full upfront estimate before any repair work starts.
What if my furnace stops working overnight in winter?
Call us at (925) 578-3379 — a live person will answer and help you assess the situation. We'll get a technician to you at the earliest available time. In the meantime, we can walk you through safe steps to stay warm.
Can I get emergency AC repair in the summer heat?
Absolutely. Summer heat emergencies — especially during heat advisories — are our most common call type. We prioritize households with elderly residents or infants.
